possibly other built-in functions). Another solution would be to add:
#ifdef __GNUC__
#define alloca(a) __builtin_alloca(a)
#else
void *alloca(size_t);
#endif
in stdlib.h, since we have assembly support for some architectures on
non-gcc environments, and we can add the rest.
programs -- doesn't affect current host tools build (groff is built the
Makefile.gnuhost way).
Provides {.cc,.cpp,.cxx,.C}.lo rule, associated variables, and HOSTPROG_CXX
support (mirroring PROG_CXX in bsd.prog.mk).
Tested with from-scratch `build.sh tools' and full system build.
it there.
The vax port's va_start() macro uses a cast, so for the moment disable
the -Wold-style-cast warning flag for the old GCC as well (as vax is
the only remaining port using this compiler).
as gcc3 generates much less false positives for -Wuninitalized and I
have found genuine bugs with this warning enabled.
Tested by building a full release of NetBSD/i386.
:M-[IDU]*
with
:C/-([IDU])[ ]*/-\1/Wg:M-[IDU]*
so that arguments with whitespace after them work correctly.
Resolves [toolchain/18248] from Andrew White at Motorola.
Be consisent in this syntax; previously we'd sometimes we'd just have :M-[ID]*
which would ignore -Ufoo ...
(This needs :C///W support in make(1) that Simon Gerraty added for me :)
* Don't bother prefixing commands with a line of ${_MKCMD}\
and instead rely upon "make -s". This is less intrusive on
all the Makefiles than the former. Idea from David Laight.
* Rename the variables use to print messages. The scheme now is:
_MKMSG_FOO Run _MKMSG 'foo'
_MKTARGET_FOO Run _MKMSG_FOO ${.TARGET}
From discussion with Alistair Crooks.
${_MKMSG} " ... {$.TARGET}" and use appropriately.
Provide _MKMSGLINK.m to provide "link" message by itself (without ${.TARGET})
Replace _MKSHCMD with _MKSHECHO
Supported values:
0 Minimal output ("quiet")
1 Describe what is occurring
2 Describe what is occurring and echo the actual command ("verbose")
This is the default, and is equivalent to the previous behaviour.
COPTS.<fn> Additional flags to the compiler when creating the C objects
for <fn>.
CPUFLAGS.<fn> Additional flags to the compiler/assembler for <fn>.
CPPFLAGS.<fn> Additional flags to the C pre-processor for <fn>.
(For <fn>.[ly], "<fn>.c" must be used.)
This replaces the previous .if defined (MANZ) behaviour, although the latter
will set MKMANZ=yes for compatibility purposes.
Don't bother with -P-bou in TOOL_ROFF_HTML; it doesn't appear to be
necessary with groff 1.19.
Fix NOHTML implementation to be consistent with other NOxxx / MKxxx
variables, and expose the user-tweakable MKHTML.
