. this function cannot have _PROF_PROLOGUE
. this function cannot be called via PLT
Change ENTRY to NENTRY for the former.
XXX: The latter is important in the gcc3 world, that have shared
libraries. We will need to play tricks with .hidden to make sure
every shared library gets its own private __udivsi3 that it can call
directly, without going through the PLT.
context-to-restore instead of always using pt_uc.
Fixes a problem with signal handlers for synchronous signals noted by
Matthias Drochner on current-users.
for that file to not be built with profiling. This makes it reasonable to
use pthread_{set,get}specific() to implement thread-safe profiline call counts.
Previously dlsym resolved to the version in crt0.o or libc which would
mean that the caller's shared object couldn't be determined correctly
using __builtin_return_address(0).
Mainly from FreeBSD, but adapted by me. Benefits of this solutions are:
- backward comptibility maintained
- existing broken binaries are fixed with a new ld.elf_so
- __mainprog_obj can be removed from crt0.o
- we do the same thing as FreeBSD
Fixes PR 22067.
OKed by Jason and Christos.
Posix requires that adding '\n' does clrtoeol() and 'x = 0'.
(Making "\r\n" erase the text that has just been displayed.)
Remove __NONL test from addbytes, __NONL is a property of the output device.
a 32 bit one with two 32 bit operations with two temporaries later
combined.
This avoids the strict alias violating magic used before, thereby
probably fixing PR bin/22313.
SYMLINKS to install symlinked header files. INCSYMLINKS are installed with
'make includes'. This avoids using SYMLINKS and hacks with the 'linkinstall'
target in <bsd.links.mk>, as linksinstall occurs in 'make install' and hacks
to get it to occur in 'make includes' weren't robust, as seen in lib/libdes.
Yet more improvements to bsd.README.
It can't be obsoleted because that causes builds with an old
${DESTDIR}/usr/include/kerberosIV/des.h to fail in directories which
have CPPFLAGS+=-I${DESTDIR}/usr/include/kerberosIV so that their #include
of <krb.h> works (and any subsequent #include <foo.h> by <krb.h>).
(Note: gcc3 won't work with a hack such as prepending -I${DESTDIR}/usr/include
before -I${DESTDIR}/usr/include/kerberosIV.)
Affected directories include lib/libkafs, and any thirdparty source
which used a similar -I/usr/include/kerberosIV hack to use <krb.h>.
* DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES.
This is a change of behaviour. If a Makefile wants the clean semantics
it must specifically append to CLEANFILES.
Resolves PR toolchain/5204.
* To recap: .d (depend) files are generated for all files in SRCS and DPSRCS
that have a suffix of: .c .m .s .S .C .cc .cpp .cxx
* If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES
* Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d depend upon ${DPSRCS}
* Deprecate the (short lived) DEPENDSRCS
Update the various Makefiles to these new semantics; generally either
adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing
specific .o dependencies with DPSRCS entries.
Tested with "make -j 8 distribution" and "make distribution".
