Rename compiler-warning-disable variables from
GCC_NO_warning
to
CC_WNO_warning
where warning is the full warning name as used by the compiler.
GCC_NO_IMPLICIT_FALLTHRU is CC_WNO_IMPLICIT_FALLTHROUGH
Using the convention CC_compilerflag, where compilerflag
is based on the full compiler flag name.
Cherry-picked from upstream:
https://git.savannah.gnu.org/gitweb/?p=config.git;a=commit;h=1c4398015583eb77bc043234f5734be055e64bea
Everything except external/apache2/llvm/dist/llvm/cmake/config.guess
is patched, which is under vendor tag and cannot be modified. I expect
that this file is not actually used as we use hand-crafted version of
configure script instead of cmake for building LLVM.
Note that external/apache2/llvm/autoconf/autoconf/config.guess has
already been committed on Oct. 20, but commit message disappeared as
cvs aborted due to "permission denied" when trying to modify the file
mentioned above. Sorry for confusing you.
Also note that GMP uses its own config.guess Patch for
external/lgpl3/gmp/dist/config.guess is provided by ryo@. Thanks!
GCC_NO_FORMAT_TRUNCATION -Wno-format-truncation (GCC 7/8)
GCC_NO_STRINGOP_TRUNCATION -Wno-stringop-truncation (GCC 8)
GCC_NO_STRINGOP_OVERFLOW -Wno-stringop-overflow (GCC 8)
GCC_NO_CAST_FUNCTION_TYPE -Wno-cast-function-type (GCC 8)
use these to turn off warnings for most GCC-8 complaints. many
of these are false positives, most of the real bugs are already
commited, or are yet to come.
we plan to introduce versions of (some?) of these that use the
"-Wno-error=" form, which still displays the warnings but does
not make it an error, and all of the above will be re-considered
as either being "fix me" (warning still displayed) or "warning
is wrong."

* src/flex.skl: scanner: Mention %# comments are removed when
building skel.c
2017-05-02 Demi Obenour <demiobenour@gmail.com>
* src/flex.skl: Honor user definitions of yy_* macros The user may have defined the yy_* macros themselves. In that case,
don't clobber them.
2017-05-02 Demi Obenour <demiobenour@gmail.com>
* src/flex.skl, src/main.c: Don't leak macro definitions into header
files This allowed unnamespaced definitions to leak into header files,
breaking client code. Fixes#142
2017-05-03 Demi Obenour <demiobenour@gmail.com>
* src/scan.l: scanner: Check for 0 bracecount when EOL ends quoted
literal. This can happen in the case of // comments (which Flex doesn't
handle specially).
2017-05-03 Demi Obenour <demiobenour@gmail.com>
* src/scan.l: scanner: when bracelevel is negative, treat as zero. This really should never happen, but this at least fixes the
breakage on Verilator.
2017-04-02 Jeff Smith <whydoubt@gmail.com>
* tests/Makefile.am, tests/tableopts.am, tests/tableopts.sh: test:
enable more silent building of tests. When running 'make V=0 check', some compile and link steps are made
less verbose and some are not. This cleans up most steps that are
not. These have no effect if V=0 is not specified.
2017-05-03 Demi Obenour <demiobenour@gmail.com>
* src/Makefile.am, src/misc.c, src/mkskel.sh: build: Delete comments
from skeleton file. Since the comments in flex.skl are, by hypothesis, not needed in
skel.c, we remove them. THis reduces the size of the resulting
executable somewhat.
2017-05-03 Explorer09 <explorer09@gmail.com>
* Makefile.am, configure.ac, lib/Makefile.am: build: do not generate
lib/Makefile.in. Files in lib/ are picked up and built using makefile directives in
src/Makefile.am. Remove the need to generate lib/Makefile.in and the
stub lib/Makefile.am.
2017-05-02 Will Estes <westes575@gmail.com>
* po/POTFILES.in: gettext: revert listing generated .c files
2017-04-10 Jeff Smith <whydoubt@gmail.com>
* src/filter.c: FLEX_EXIT() is the preferred way to exit flex
2017-04-11 Explorer09 <explorer09@gmail.com>
* src/misc.c: Fix myesc() 'sptr' conditionals * Don't call isascii() here. It's deprecated in POSIX and not needed for myesc's case. * The check of the character class and range here should match
what's defined as {ESCSEQ} in scan.l, so for [[:xdigit:]] we use
isxdigit(); for [0-7] we check '0' <= c <= '7' (not isdigit(c)
because isdigit is locale-dependant in standard's sense) * Add missing length limit for "\x<hex>" (<hex> is at most 2 digits)
2017-04-11 Explorer09 <explorer09@gmail.com>
* src/flexdef.h, src/misc.c: Obsolete htoui() and otoui(); use
strtoul(). No sense to keep these two function when libc's strtoul() can do the
same job, but better.
2017-04-12 Todd C. Miller <Todd.Miller@courtesan.com>
* src/flex.skl: scanner: update yy_buf_size after yyrealloc()
2017-05-02 Simon Sobisch <simonsobisch@web.de>
* configure.ac: build: use lowest versions for gettext, automake.
2017-05-02 Simon Sobisch <simonsobisch@web.de>
* po/Makevars, po/Rules-getpo, po/update_linguas.sh: gettext: more
recent makevars; new script to update po files. Previously, "make dist" and similar commands would cause the po
files to be updated, which is incorrect. The more recent version now
used should not do this. Replaced Rules-getpo by extra script to manually update and rebuild
all po files.
2017-05-02 Simon Sobisch <simonsobisch@web.de>
* po/POTFILES.in: gettext: list generated files instead of flex,
bison sources in POTFILES.in. Listing the flex and bison sources -- as the gettext manual suggests
-- causes warnings. Listing the generated C files for the lexer and
parser removes the warnings. Since both files contain line
directives, any translator who needs to refer back to those files
should be able to find the context in which strings are needed.
2017-05-02 Simon Sobisch <simonsobisch@web.de>
* autogen.sh: build: only touch ChangeLog if it does not exist
2017-05-02 Simon Sobisch <simonsobisch@web.de>
* configure.ac, doc/Makefile.am: build: list earliest useable
versions for automake
2017-05-02 Simon Sobisch <simonsobisch@web.de>
* autogen.sh: build: check for how to call libtoolize. Previously, we would call libtoolize and if that failed, we would
call glibtoolize since some platforms have the libtoolize program
under that name. Instead, we check to see if the environment variable LIBTOOLIZE is
set and use that if so. Otherwise, we try to find a program
"libtoolize" on the path and failing that glibtoolize. We alert the
user if no suitable program can be found.
2017-01-06 Alastair Hughes <hobbitalastair@gmail.com>
* configure.ac, m4/ax_prog_cc_for_build.m4, src/Makefile.am: build:
support cross compiling. Check for cross compiling. If cross compiling, build stage1flex
using a custom link command. We also override LDADD since that adds
the replacement implementations that are cross compiled, and instead
always use the replacement library implementations. We don't use BUILD_OBJEXT and BUILD_EXEEXT since it seems that
automake does not support these. Fixes#78.
2017-02-17 Explorer09 <explorer09@gmail.com>
* configure.ac, src/flexdef.h: build: Include <strings.h>; add
strcasecmp() check to configure. strings.h (not string.h) is the standard-defined include header for
strcasecmp(). Include <strings.h> for portability (even though glibc
exposes strcasecmp() declaration also in <string.h> by default).
2017-02-17 Explorer09 <explorer09@gmail.com>
* configure.ac, src/flexdef.h: build: Let configure error if missing
required functions, headers.. `configure` will now error if a required header or function is not
found on the system. Also add comments on optional functions checks. Add sys/stats.h and sys/wait.h to list of required headers in
configure. This fixes issue #180.
2017-02-12 Explorer09 <explorer09@gmail.com>
* src/dfa.c, src/flexdef.h: scanner: compute powers of two faster. Replace the naive "for" loop in determining power of two with a
clever bitwise solution. This code is around the Internet already
and is in Public Domain.
2017-02-07 Explorer09 <explorer09@gmail.com>
* configure.ac, tests/Makefile.am, tests/pthread.l: test: skip
pthread test when needed files missing. "Unlisting" the pthread test when libpthread is not available is
never a good idea. Should let it compile into a stub program that
returns the "skip" status. configure.ac and tests/Makefile.am are edited so that pthread test
can be built anyway, but only works (not as the stub) when both
pthread.h and libpthread are detected on the system. Also fix a small typo in tests/pthread.l comments.
2017-02-16 Will Estes <westes575@gmail.com>
* src/Makefile.am: build: mv scan.c when building dist. Revert change to copy scan.c when building the distribution archive.
Move it instead. This satisfies automake's notions of what should be
clean and ensures that the distribution archive contains a
just-built copy of scan.c. Fixes#186
2017-02-06 Will Estes <westes575@gmail.com>
* src/Makefile.am: build: don't assume distdir/scan.c is writeable
2017-01-02 Explorer09 <explorer09@gmail.com>
* src/Makefile.am: build: Add dist-hook to force remake scan.c. This will ensure the flex scanner included in release tarball being
generated by exactly the flex version to be released. Here's one catch after this change: You may not run "make dist" or
"make distdir" if you configure the flex source to be
cross-compiled.
2017-01-02 Explorer09 <explorer09@gmail.com>
* src/Makefile.am: build: respect '--localedir' from configure. Makefile shouldn't overwrite the 'localedir' variable, because
that's what '--localedir' option in 'configure' is for.
2017-01-02 Explorer09 <explorer09@gmail.com>
* src/Makefile.am: build: Remove "-I$(top_srcdir)/intl" from
CPPFLAGS. Revert commit e02c3d27eeb6b53ec82532ab080c23ce26813fd4 ("include the intl/ subdirectory when searching for include files") Flex doesn't come with libintl source code, so inclusion of
$(top_srcdir)/intl subdirectory during compiling is unnecessary. This flag seems to be left after "remove intl from dist" (commit
8f45da06adbd7dbcdfdbdd5c20ff4c47fc504f35) without someone cleaning
this up. Users who need to build with gettext functionality from libintl
would use the '--with-libintl-prefix' configure option.
2017-02-03 Explorer09 <explorer09@gmail.com>
* src/regex.c: scanner: fix regcomp's error reporting, double
malloc. Fix unneeded double malloc - let regerror(). Write its message after
our "regcomp for (regex) failed: " string. Also, errbuf cannot be free()'d because of flexfatal containing a
longjmp.
2017-01-03 Explorer09 <explorer09@gmail.com>
* tests/Makefile.am, tests/no_bison_stub.c: test: Skip bison tests
if bison is not available
2017-01-03 Explorer09 <explorer09@gmail.com>
* configure.ac: build: remove repeated bison detection from
configure. AC_PROG_YACC already detects the bison program. We can just use it,
and make notice if [ $YACC != 'bison -y' ] Remove unused AC_SUBST([BISON], ...). Add AM_CONDITIONAL([HAVE_BISON], ...) so that we can skip bison
tests in testsuite when bison is absent. We don't make any attempt to detect other yacc implementations since
flex is developed with bison. While it would be possible, the need
isn't there right now. It would be possible to add a --with-parser
option that defaulted to bison if such a need cropped up.
2017-01-01 Explorer09 <explorer09@gmail.com>
* src/Makefile.am: build: fix Makefile parse.h dependency clauses. The current clauses stating "main.c: parse.h" and "yylex.c: parse.h"
do not work as expected. Make did not try to build parse.h upon
building flex-main.o as it would think main.c exist already and
ignore the clause. Fix this by explicitly stating that the .o files
depend on parse.h instead. This dependency bug only happens if user builds flex from a
checked-out repository.
2017-01-03 Explorer09 <explorer09@gmail.com>
* tests/Makefile.am: test: Remake *_scanner.c if *_scanner.h is
missing. If a ${foo}_scanner.c exists but the respective ${foo}_scanner.h is
missing, then 'make' can halt. Fix this by deleting the
${foo}_scanner.c file and then remake it. This rule is the same as
the automake-generated rule for .c files that require LEX or YACC
(except automake will use ylwrap).
2016-12-31 Explorer09 <explorer09@gmail.com>
* tests/Makefile.am: test: remove BUILT_SOURCES; add missing
dependencies. Without BUILT_SOURCES in Makefile, no test sources in tests/ will be
built when using the default "make all" target. This is desireable
for people who are just building flex but who do not want to run,
and therefore, build any part of the test suite. Also fix missing sources dependencies: bison_nr_scanner.$(OBJEXT): bison_nr_parser.h bison_yylloc_scanner.$(OBJEXT): bison_yylloc_parser.h bison_yylval_scanner.$(OBJEXT): bison_yylval_parser.h
2017-01-19 Explorer09 <explorer09@gmail.com>
* configure.ac, lib/reallocarray.c, src/flexint.h, src/misc.c:
build: detect overflow for [re]allocate_array. Use reallocarray() when we have it (i.e. in OpenBSD system). When we
don't, use equivalent overflow detection for our allocate_array and
reallocate_array functions. Remove lib/reallocarray.c from our LIBOBJS as we no longer need it. Provide a fallback SIZE_MAX macro definition in flexint.h (not
preprocessor friendly, but enough for our reallocate_array use
case).
2017-01-23 Will Estes <westes575@gmail.com>
* NEWS, configure.ac: doc: v2.6.4
2017-01-23 Thomas Klausner <wiz@NetBSD.org>
* src/Makefile.am: build: more BSD make and vpath build fixes. BSD make doesn't like $< with more than one source specified.
Additionally, make sure to specify srcdir when referring to source
files since vpath builds depend on this.
2017-01-22 Thomas Klausner <wiz@NetBSD.org>
* src/Makefile.am: build: Fix skel.c generation with BSD make
2017-01-22 Christos Zoulas <christos@zoulas.com>
* src/flex.skl: Add more defines in the non-reentrant part. Fix the reentrant part; don't "#define yyfoo yyfoo" because it
breaks code that does #ifndef yywrap ..
2017-01-22 Christos Zoulas <christos@zoulas.com>

* src/misc.c: scanner: Use array instead of pointer
2017-01-22 Christos Zoulas <christos@zoulas.com>
* src/main.c: scanner: manage path to m4 better. Avoid alloca() for SSP; it is better anyway; since we don't need to
strdup the path.
2017-01-22 Christos Zoulas <christos@zoulas.com>
* src/gen.c: scanner: Avoid creating unused label
2017-01-22 Christos Zoulas <christos@zoulas.com>
* src/buf.c: Cast argument to avoid arithmetic on void *.
2017-01-22 Christos Zoulas <christos@zoulas.com>
* src/scan.l: scanner: Use strncpy
2017-01-22 Christos Zoulas <christos@zoulas.com>
* src/main.c: scanner: Use prefix when defining yywrap to avoid
redefinition. Fixes regression introduced in v2.6.3.
2017-01-22 Christos Zoulas <christos@zoulas.com>
* src/flexdef.h, src/misc.c: scanner: Include stdarg.h for va_list
2017-01-22 Christos Zoulas <christos@zoulas.com>
* src/flexdef.h, src/main.c, src/parse.y: scanner: Rename warn to
lwarn. This avoids a naming conflict in NetBSD's libc.
2017-01-01 Explorer09 <explorer09@gmail.com>
* tests/README: test: document automake convention for skipped exit
status.
2017-01-03 Explorer09 <explorer09@gmail.com>
* tests/Makefile.am: test: let testwrapper scripts be run by
${SHELL}. This allows user to use a different shell if /bin/sh has problems.
The use of $SHELL (variable) to run scripts is already an Automake
convention. All shell scripts in build-aux are run by $SHELL.
2017-01-02 Explorer09 <explorer09@gmail.com>
* tests/options.cn, tests/tableopts.sh,
tests/testwrapper-direct.sh, tests/testwrapper.sh: test: Remove test
scripts bashisms. They now all work under a POSIX compliant sh. Specifically, 'dash'
can now be used for running "make check" tests. Note that none of these scripts has ever been using a pipe, so `set
-o pipefail` is unnecessary and removed.
2017-01-02 Explorer09 <explorer09@gmail.com>
* tests/testwrapper.sh: test: exit on '-1' test non-zero status. If a '-1' test program returns a non-zero status, don't go further
and compare it's (numeric) output values. This allows a '-1' test to
indicate a "skip" status or an otherwise error. (Currently no such
'-1' test would skip like this, though.) Shell syntax note: `set -e` will not exit with the syntax like this
`test $(false) = $(false);`. The exit statuses of `false` in the
example will be ignored instead. But putting the output in a
variable, such as `VAR=$(false)`, DOES exit.
2017-01-02 Explorer09 <explorer09@gmail.com>
* Makefile.am, src/Makefile.am: build: Fix 'make indent' target This 'make indent' target has not been working since the directories
reorganization in flex 2.6.0. Now make it work again. Note that the current indent profile breaks many styles of existing
code. The indent target should not be used until the .indent.pro
options are reviewed for desireability.
2017-01-01 Explorer09 <explorer09@gmail.com>
* configure.ac: build: Simplify indent program detection
2017-01-12 Tobias Klauser <tklauser@distanz.ch>
* src/filter.c: filter: Don't emit #line if %option noline set One place emitting a #line directive to the generated header was
missed in commit 647a92b9f4 when resolving #55. Fix it to respect
gen_line_dirs as well.

2017-01-10 Harald van Dijk <harald@gigawatt.nl>
* src/flex.skl: c++: Fix yyrestart(NULL) SEGV. Binding a reference to a dereferenced null pointer is invalid and
compilers optimise away the &file == 0 check. We need a real stream. yyin is available already, and yyrestart(NULL) is only supported
when yyin will not be used, so there is no harm in just passing in
that. Since we now always have a valid stream, we can skip the null
check too. Fixes#98.
2017-01-09 luistung <dongliang1986@gmail.com>
* src/scan.l: scanner: join symbol list. Removed a newline that caused a problem building the scanner in some
circumstances. Specifically: 'bad character' error when executing /bin/sh ../build-aux/ylwrap scan.l lex.yy.c scan.c -- flex
2017-01-11 Will Estes <westes575@gmail.com>
* src/flex.skl: scanner: remove void cast before fprintf
but only weird code?):
amd's amfs_program_exec() has a missing {} issue.
flex's check_options() has odd inconsistent identation that
trips the new ident checker.
ntpd's oncore_check_leap_sec() and oncore_set_traim() have
missing {} issues.
sntp's optionLoadNested() an identation weirdness that
trips the new ident checker.
vi's cl_attr() has a wrong {} issue, and its vs_paint() has
an identation weirdness that trips the new ident checker.
introducing since release of software to be recognised. This should hopefully
allow the builds to progress a littles further on systems such as the POWER8
which features a little endian 64-bit PowerPC CPU identified as ppc64le.
* NEWS: doc: update NEWS for 2.6.3 release
2016-11-26 Explorer09 <explorer09@gmail.com>
* configure.ac, src/Makefile.am: build: New configure option
'--disable-bootstrap'. If configure is run with '--disable-bootstrap', then stage1flex
won't be built and stage1scan.c will be generated by sed'ing scan.c. This option is intended to workaround bootstrap bugs rather than to
fix the bootstrapping issues which are proving subtler and harder to
fix than anyone would like.
2016-11-26 Explorer09 <explorer09@gmail.com>

2016-11-26 Explorer09 <explorer09@gmail.com>
* configure.ac, src/Makefile.am: build: allow building libfl even

configure has been run with the --disable-libfl option. This is
possible, now, via 'make -C src libfl.la'.

* src/main.c: scanner: allocate correct buffer size for m4 path. Flex did not check the length of the m4 path which could lead to a
buffer overflow in some cases. Additionally, not all platforms
believe in PATH_MAX, so stop relying on it. Fixes#138

* NEWS, doc/Makefile.am: Only regenerate the man page when required. Make the flex binary an order-only prerequisite, and add back the
prerequisites from before 7cfb440. This prevents rebuilding the man
page whenever the flex binary is rebuilt, which causes problems if
help2man is not installed and will never work when cross compiling. Fixes#108.

* NEWS, src/Makefile.am: build: no longer build PIC version of
libfl. The PIC version of libfl was not being built correctly. From the
lack of bug reports around this problem, we conclude that the PIC
version of libfl is not used and so we drop it from the build build
targets for flex.

section 3 of the input file only) and character literals. The new
quotation method is also less brittle and faster. Tests that relied on the old behavior were fixed. Also, `yyconst` is no longer defined; use `const` (which it
unconditionally was defined to) instead.

escape sequences and character constants. Tests were added to verify the behavior in section 3 with respect to
quoting. Both escaping of quotes and quoting of potential
macro-start characters are tested. Existing tests were also fixed to
account for the new -- and now correct -- behavior. Many tests
relied on the old behavior of expanding M4 macros in section 3.
They needed to be updated for the new behavior.

* src/scanflags.c: Avoid realloc on every call of sf_push() Currently, every call to sf_push() realloc()'s _sf_stack, even if
the maximum size _sf_max wasn't changed. As the indentation beneath
the "if" clause already indicates, the realloc() should only be
executed if _sf_max was increased. Found by compiling flex with the -Wmisleading-indentation flags of
gcc, which leads to the following warning: scanflags.c: In function âsf_pushâ: scanflags.c:42:5: warning:
this âifâ clause does not guard... [-Wmisleading-indentation] if
(_sf_top_ix + 1 >= _sf_max) ^~ scanflags.c:44:9: note: ...this

gen_line_dirs. Fix them, so they also respect gen_line_dirs. Signed-off-by: Tobias Klauser <tklauser@distanz.ch>

* lib/lib.c, src/gen.c, src/misc.c, src/scan.l: Converted K&R style
function definitions to ANSI C style Consistently make use of the ANSI C function definition style
instead of the K&R style.
2016-01-29 Tobias Klauser <tklauser@distanz.ch>
* src/flex.skl: Used NULL constant instead of plain integer for NULL
pointer. The sparse static checker warns about using plain integer 0 as NULL
pointers in the generated lexer code. Fix this by using NULL
consistently for pointers.
2016-01-29 Tobias Klauser <tklauser@distanz.ch>
* src/flex.skl: Marked declaration and definition of yy_fatal_error
as noreturn. Only the declaration of yy_fatal_error is marked with
__attribute__((__noreturn__)) in case GCC >= 3 is used, but not the
definition. This leads to the sparse static checker to complain
about function declaration mismatch. Fix it by defining a macro yynoreturn and using it for both the
declaration and the definition of yy_fatal_error.
2016-01-27 Tobias Klauser <tklauser@distanz.ch>
* src/flex.skl: Fixed declaration mismatch in yy_fatal_error. The prototype declares yy_fatal_error parameter as "const char
msg[]" while the definition uses "const char* msg" (introduced by
commit e9d5fc713f61b) which causes the sparse static checkers to
produce an error. Fix this by adjusting the definition to use "const char* msg" as
well. Also change the C++ version accordingly so it matches the
declaration in FlexLexer.hpp.

* configure.ac, src/flexdef.h: Removed no longer needed header
checks
2015-12-27 Will Estes <westes575@gmail.com>
* configure.ac: Checked for reallocarray() with AC_REPLACE_FUNCS
2015-12-27 Will Estes <westes575@gmail.com>
* src/flexdef.h, src/main.c: include libgen.h from flexdef.h, not
main.c
2015-12-25 Michael Reed <m.reed@mykolab.com>
* src/main.c: Replace basename2() with basename(3). Given the following program: \#include <libgen.h> \#include <stdio.h> /* extracts basename from path, optionally stripping the extension
"\.*" * (same concept as /bin/sh `basename`, but different handling
of extension). */ static char *basename2 (char *path) { char *b; for (b = path; *path; path++) if (*path == '/') b = path + 1; return b; } static void basename_compare(char *path) { printf("basename: %s\n", basename(path)); printf("basename2: %s\n\n", basename2(path)); } int main (int argc, char *argv[]) { // From http://pubs.opengroup.org/onlinepubs/9699919799/ // ``Sample Input and Output Strings'' basename_compare("/usr/lib"); basename_compare("/usr/"); basename_compare("/"); basename_compare("///"); basename_compare("//usr//lib//"); return 0; } ... and the program's output: basename: lib basename2: lib basename: usr basename2: basename: / basename2: basename: / basename2: basename: lib basename2: ... we can see that basename2() behaves the same as basename(3) in
the average use case, but messes up pretty severely in others.
Besides that, basename(3) is mandated by POSIX so should be present
on modern Unix-like systems, so we shouldn't define it ourselves. Some notes: - it doesn't appear to be mentioned in POSIX, but OpenBSD's
basename(3) returns NULL if the returned path componenet is >
PATH_MAX, so add a check for that - basename(3) shouldn't return an empty string, so remove the program_name[0] != '\0' check
2015-12-25 Michael Reed <m.reed@mykolab.com>
* src/main.c: Simplify basename2(). It's only call site does not activate the `strip_ext` code path, so
the function can be simplified a lot. While here, remove a double
assignment.
2015-12-25 Michael Reed <m.reed@mykolab.com>
* src/flex.skl, src/misc.c: Cleaned up __STDC__ #ifdefs. Assuming a compiler conforming to the ISO C standard is used, i.e.,
__STDC__ is defined to 1, YY_USE_CONST is always defined and can be
eliminated.

* src/gen.c, to.do/unicode/gen.c: Removed macros for indentation
level. Just increment or decrement the indentation counter. That's less to
remember and makes the code more readable. w# Please enter the commit message for your changes. Lines starting
2015-12-12 Mike Frysinger <vapier@gentoo.org>
* tests/Makefile.am, tests/testwrapper.sh: tests: fixed paths to
input files. The current test wrapper works only when the inputs are specified
using relative paths. If they're specified with absolute paths, the
driver fails to detect the inputs because it always prepends the
input dir name which itself is a relative path: $ cd tests $
./testwrapper.sh -d . -i $PWD/reject.txt -t ./reject_ver.table
<fails to open inputs> This normally doesn't show up because people run `./configure` or,
for out of tree builds, `../configure`. But if you happen to run
configure with an absolute path, then automake tends to generate
absolute paths as well leading to test failures. Fix all of this by dropping the implicit input directory prepending. - INPUT_NAME is often a list of files, not just a single one - the input directory is used to find the testname tables which are usually generated, so it's impossible to use files from both
source and build directories - most of the time, the full/correct path is already specified
2015-12-12 Mike Frysinger <vapier@gentoo.org>
* configure.ac: configure: fixed realloc test. The [] characters are used for quoting in m4, so the attempt to use
them in place of `test` fails yielding the warning at build time: .../flex/configure: line 20222: no: command not found
2015-12-12 Michael McConville <mmcco@mykolab.com>
* src/flexdef.h: Started removal of PROTO macro. The PROTO macro is no longer needed. Additionally, its usage is
inconsistent, so we began removing it.
2015-12-12 Michael Reed <m.reed@mykolab.com>
* Makefile.am, src/main.c: Removed SHORT_FILE_NAMES preprocessor
symbol. As a relic of MS-DOS, we don't need this. It's never defined; see 13b5b214f53d1c3354a7ab910bd160c126df1331. Removed additional MSDOS ifdef.
2015-12-11 Michael McConville <mmcco@mykolab.com>
* configure.ac, lib/reallocarray.c, src/flexdef.h: Added new
function reallocarray. This is taken from OpenSSH Portable, which in turn takes it from
OpenBSD. reallocarray wraps the stdlib's realloc function. It takes two size
arguments and checks for overflow, like calloc, but doesn't zero the
memory. Therefore, it allows us to do overflow-safe array
reallocations and overflow-safe unzeroed array allocations, which
the stdlib allocation functions don't. We have a bunch of specific array allocation macros, none of which
check for overflow. reallocarray should be able to replace them.
2015-12-11 Michael McConville <mmcco@mykolab.com>
* src/flexdef.h: Removed MS-DOS, VMS macros. Given the age of the MS-DOS and VMS platforms, it's likely that no
one is building flex on them any more. Additionally, the preferred
approach is to test for particular platform features rather than to
test for particular platforms.

2015-12-09 Michael McConville <mmcconville@mykolab.com>
* src/flexdef.h: Removed implementation of isascii(). POSIX defines isascii(), so it's likely present on anything
weactually build flex on these days.
2015-12-09 Michael McConville <mmcconville@mykolab.com>
* src/main.c, src/scanopt.c, src/tables.c: Removed NULL-checks

* src/buf.c, src/dfa.c, src/flexdef.h, src/gen.c, src/scan.l,
to.do/unicode/flexdef.h, to.do/unicode/scan.l: Removed flex_free()i,
corrected buf_destroy logic. As with flex_alloc(), replace with direct calls to free(). The function buf_destroy is now null safe and the logic was
corrected to free() correctly.

src/scanflags.c, to.do/unicode/flexdef.h, to.do/unicode/misc.c,

just a wrapper around realloc().

* src/buf.c, src/filter.c, src/flexdef.h, src/main.c, src/misc.c,
src/regex.c, src/scan.l, src/scanflags.c, src/sym.c,
to.do/unicode/flexdef.h, to.do/unicode/misc.c, to.do/unicode/scan.l:
Removed flex_alloc; cleaned up style. The function flex_alloc() was just a wrapper around malloc(). Since
this only added unclarity, and the flex_alloc() function is likely a
legacy of olden times, remove it in favor of calls to malloc()
directly. Style elements cleaned up: * superfluous spacing around parentheses * non-constant initialization in variable declarations * needless casts * almost all uses of assignments as subexpressions

2015-12-07 Will Estes <westes575@gmail.com>
* src/.gitignore, src/Makefile.am: Built flex with itself. Changes in scan.l need to be built into flex with the same version
of flex in some cases. Since this build requirement is minimal, we
simply bootstrap flex unconditionally. We intentionally exclude from version control the bootstrap
artifacts as the extra copy of the lexer, the intermediate scanner
and the bootstrap executable are not of interest.

* src/flexdef.h, src/misc.c, src/sym.c, to.do/unicode/flexdef.h,
to.do/unicode/misc.c: Replace copy_unsigned_string() with xstrdup(). Like copy_string(), copy_unsigned_string() is just a clone of the
stlib's strdup(). We only use it twice. I'm pretty confident that
char signedness is irrelevant in this case.

* examples/testxxLexer.l, src/FlexLexer.h, src/flex.skl, src/main.c:
Replaced FLEX_STD macro with std::. The std:: construct exists as of C++98, so we can simply assume it
is supported.
2015-12-04 Akim Demaille <akim@lrde.epita.fr>
* src/Makefile.am: Generated skel.c explicitly in srcdir. Rewrote the target for skel.c to explicitly mention the srcdir. This
should help when building flex from a directory outside the flex
tree. Spread the rule out over several lines to enhance readability.
2015-12-04 Akim Demaille <akim@lrde.epita.fr>
* autogen.sh: Called glibtoolize if libtoolize run fails. On Mac OS X, libtoolize is known as glibtoolize. In cases where
libtoolize is not present, then calling glibtoolize when
bootstrapping the build system gives more folks a shot at getting
flex built from the ground up.
2015-12-02 Mightyjo <mightyjo@gmail.com>
* configure.ac: Checked for (g)texi2dvi. Better bison, help2man
checks. Added test for presence of (g)texi2dvi program. Gave notice if
texi2dvi is unavailable and set TEXI2DVI=: to avoid giving users
headaches. Enhanced tests for bison and help2man with notices when the programs
aren't found. Set their program variables to use the missing script
in build-aux since it's compatible with them.

src/tables.c, to.do/unicode/flexdef.h, to.do/unicode/misc.c,
to.do/unicode/scan.l: Made string copying more standard. copy_string() was a clone of the stdlib's strdup(). For safety,
simplicity, and speed, we should use that instead. We introduce
xstrdup() which wraps strdup() in a failure upon memory allocation
errors.
2015-11-30 Serguey Parkhomovsky <sergueyparkhomovsky@gmail.com>
* src/scan.l: Error on unbalanced parentheses in rules section.
2015-11-29 Will Estes <westes575@gmail.com>

* src/ecs.c, src/flexdef.h, src/main.c, src/misc.c, src/scan.l,
src/scanopt.c, src/sym.c, src/tblcmp.c: Replaced CHAR macro with
unsigned char type. Thanks to Michael McConville for pointing out that the old Char
macro causes problems with static analysis. The macro has been
removed and replaced with 'unsigned char' throughout the flex
sources. The macro is not needed at best and was confusing at worst.
It was not used in any of the example files nor was it mentioned in
the manual at all.
