aclocal.m4 (libiberty_AC_FUNC_C_ALLOCA): New.

Browse Source 
libiberty:
	* aclocal.m4 (libiberty_AC_FUNC_C_ALLOCA): New.
	* configure.in: Replace all alloca logic with a simple use of
	the above new macro.
	* config.table: Kill *-*-beos* entry.
	* config/mh-beos: Delete.
	* configure, config.in: Regenerate.

	* Makefile.in (ALLOCA, HFILES): Kill.
	(REQUIRED_OFILES): Add alloca.o.
	(alloca.o): Depend on libiberty.h.
	(argv.o): Don't depend on alloca-conf.h.
	* alloca-conf.h: Delete.
	* alloca.c: Include libiberty.h.  Kill all #ifdef emacs
	blocks.  Provide the C alloca unconditionally.  Use PTR where
	appropriate.  Make i00afunc static.
	* argv.c: Don't include alloca-conf.h.

include:
	* libiberty.h: Prototype C_alloca; define alloca to either
	__builtin_alloca or C_alloca as appropriate.

gcc:
	* aclocal.m4 (AM_GNU_GETTEXT): Don't AC_REQUIRE
	AC_FUNC_ALLOCA.
	* configure, config.in: Regenerate.
	* config.gcc: Remove references to deleted files.

	* genattr.c, genattrtab.c, genextract.c, genoutput.c,
	genrecog.c, rtl.c: Do not use alloca anywhere.

# The svr4 reference port for the i860 contains an alloca.o routine
# in /usr/ucblib/libucb.a, but we can't just try to get that by
# setting CLIB to /usr/ucblib/libucb.a because (unfortunately)
# there are a lot of other routines in libucb.a which are supposed
# to be the Berkeley versions of library routines normally found in
# libc.a and many of these Berkeley versions are badly broken. Thus,
# if we try to link programs with libucb.a before libc.a, those
# programs tend to crash.
# Also, the alloca() routine supplied in early version of svr4 for
# the i860 is non-ABI compliant. It doesn't keep the stack aligned
# to a 16-byte boundary as the ABI requires.
# More importantly however, even a fully ABI compliant alloca() routine
# would fail to work correctly with some versions of the native svr4 C
# compiler currently being distributed for the i860 (as of 1/29/92).
# The problem is that the native C compiler generates non-ABI-compliant
# function epilogues which cut back the stack (upon function exit) in
# an incorrect manner. Specifically, they cut back the stack by adding
# the nominal *static* frame size (determined statically at compile-time)
# to the stack pointer rather than setting the stack pointer based upon
# the current value of the frame pointer (as called for in the i860 ABI).
# This can cause serious trouble in cases where you repeatedly call a
# routine which itself calls alloca(). In such cases, the stack will
# grow continuously until you finally run out of swap space or exceed
# the system's process size limit. To avoid this problem (which can
# arise when a stage1 gcc is being used to build a stage2 gcc) you
# *must* link in the C language version of alloca() which is supplied
# with gcc to your stage1 version of gcc. The following definition
# forces that to happen.
