2012-04-24  Sam Steingold  <sds@gnu.org>

	Never build shared libraries: --enable-shared has no effect.
	* avcall/Makefile.in (libavcall.la): pass -static to LIBTOOL_LINK
	* callback/Makefile.in (libcallback.la): ditto
	* callback/trampoline_r/Makefile.in (libtrampoline.la): ditto
	* callback/vacall_r/Makefile.in (libvacall.la): ditto

2010-09-03  Sam Steingold  <sds@gnu.org>

	* configure.in: call AC_CONFIG_AUX_DIR(build-aux)

2010-09-03  Sam Steingold  <sds@gnu.org>

	* Makefile.devel (gnulib-imported): also import host-cpu-c-abi
	* avcall/configure.in, callback/configure.in:
	* callback/trampoline_r/configure.in, callback/vacall_r/configure.in:
	* trampoline/configure.in, vacall/configure.in:
	use gl_HOST_CPU_C_ABI instead of FFCALL_CANONICAL_HOST_CPU
	* m4/general.m4: remove FFCALL_CANONICAL_HOST_CPU,
	FFCALL_CACHE_EGREP_CPP, FFCALL_SET_CPU_ABI
	* glm4/host-cpu-c-abi.m4: add
	* avcall/Makefile.in, callback/Makefile.in:
	* callback/trampoline_r/Makefile.in, callback/vacall_r/Makefile.in:
	* trampoline/Makefile.in, vacall/Makefile.in,
	use @HOST_CPU_C_ABI@ instead of @host_cpu_abi@
	* callback/trampoline_r/configure.in, trampoline/configure.in:
	* m4/codeexec.m4: use $HOST_CPU_C_ABI instead of $host_cpu_abi

2010-07-20  Sam Steingold  <sds@gnu.org>

	* callback/trampoline_r/trampoline_r.h.in, trampoline/trampoline.h.in:
	add autoconf CPU detection block; this fixes trampoline on sparc64/linux
	Suggested by Valeriy E. Ushakov <uwe@netbsd.org>

2010-07-20  Valeriy E. Ushakov  <uwe@netbsd.org>

	https://savannah.gnu.org/bugs/?22081
	support sparc64 for solaris & *bsd
	* avcall/avcall-sparc64.c, avcall/avcall.h.in:
	Kill callee (%g2). Sparc64 doesn't need that code.
	Delete space[] - gcc optimizes it away anyway, and it doesn't
	guarantee correct operation even if it's not removed - if compiler
	allocs it below other local vars on the stack, then calling
	function with enough arguments will clobber local vars.
	Instead i've changed the code to use alloca, see the comment in
	the code for details on why this works. It also doesn't waste 2K
	of stack on each call, we only grab the space we actually need.
	I nuked farg_mask. It's not necessary for float args, marking
	them in darg_mask does the right thing (new av_float). And they
	just hurt structure passing, where, again, marking up darg_mask
	does the right thing.
	* avcall/avcall-saprc64.S: Regenerated with NetBSD gcc4
	* vacall/vacall-sparc64.S, callback/vacall_r/vacall-sparc64.S:
	New binutils on sparc64 insist on having global registers properly
	declared with .register. I've just added the declarations manually
	w/out actually regenerating the files to demonstrate that's the
	only change needed there. IF the files are regenerated with a
	newer compiler you will get them automatically.

2009-11-10  Sam Steingold  <sds@gnu.org>

	* vacall/Makefile.in (vacall-armel.o): vacall-armel.s is in $(srcdir)
	* callback/vacall_r/Makefile.in (vacall-armel.lo): ditto

2009-10-16  Sam Steingold  <sds@gnu.org>

	the final fix for LIBFFCALL_VERSION
	* Makefile.devel (vacall/vacall.h.msvc, vacall/vacall.h.mingw32)
	(callback/vacall_r/vacall_r.h.msvc)
	(callback/vacall_r/vacall_r.h.mingw32): depend on VERSION
	* avcall/avcall.h.in, callback/callback.h.in,
	* callback/trampoline_r/trampoline_r.h.in, vacall/vacall.h.in,
	* callback/vacall_r/vacall_r.h.in, trampoline/trampoline.h.in:
	use @LIBFFCALL_VERSION@ instead of @PACKAGE_VERSION@
	* avcall/configure.in: additional processing for avcall.h to
	substitute @LIBFFCALL_VERSION@
	* callback/configure.in: ditto for callback.h
	* callback/trampoline_r/configure.in: ditto for trampoline_r.h
	* callback/vacall_r/configure.in: ditto for vacall_r.h
	* trampoline/configure.in: ditto for trampoline.h
	* vacall/configure.in: ditto for vacall.h
	* callback/vacall_r/Makefile.devel (vacall_r.h.msvc)
	(vacall_r.h.mingw32): depend on ../../VERSION;
	substitute @LIBFFCALL_VERSION@
	* vacall/Makefile.devel (vacall.h.msvc, vacall.h.mingw32): depend
	on ../VERSION; substitute @LIBFFCALL_VERSION@

2009-10-16  Sam Steingold  <sds@gnu.org>

	* glm4/longlong.m4, glm4/nocrash.m4: update from gnulib

2009-10-16  Sam Steingold  <sds@gnu.org>

	* Makefile.devel (update-gnulib): use git when available

2009-10-16  Sam Steingold  <sds@gnu.org>

	* avcall/configure.in, callback/configure.in,
	* callback/trampoline_r/configure.in, callback/vacall_r/configure.in,
	* trampoline/configure.in, vacall/configure.in: list the main generated
	header (avcall.h et al) in AC_CONFIG_HEADERS, not in AC_CONFIG_FILES
	fixes the bug#27706 (introduced on 2009-04-24)

2009-04-28  Sam Steingold  <sds@gnu.org>

	* m4/general.m4 (FFCALL_CACHE_EGREP_CPP, FFCALL_SET_CPU_ABI):
	abstracted out of FFCALL_CANONICAL_HOST_CPU
	(FFCALL_CANONICAL_HOST_CPU): use them

2009-04-27  Max Lapan  <max.lapan@gmail.com>
	Sam Steingold  <sds@gnu.org>

	* avcall/Makefile.devel, avcall/Makefile.in, avcall/avcall.h.in,

	Add ARMel support <https://savannah.gnu.org/bugs/?22492>
	* m4/general.m4 (FFCALL_CANONICAL_HOST_CPU): use AC_EGREP_CPP to
	distinguish between arm and armel

	* callback/trampoline_r/cache-armel.c,
	* callback/trampoline_r/cache-armel.s,

	new files

	* Makefile.in, avcall/Makefile.in, callback/Makefile.in,
	* callback/trampoline_r/Makefile.in, callback/vacall_r/Makefile.in,

dnl From Bruno Haible and Sam Steingold.

dnl Sets the HOST_CPU_C_ABI variable to the canonical name of the CPU with its
dnl C language ABI (application binary interface).
dnl Also defines __${HOST_CPU_C_ABI}__ as a C macro in config.h.
dnl
dnl This canonical name can be used to select a particular assembly language
dnl source file that will interoperate with C code on the given host.
dnl
dnl For example:
dnl * 'i386' and 'sparc' are different canonical names, because code for i386
dnl   will not run on SPARC CPUs and vice versa. They have different
dnl   instruction sets.
dnl * 'sparc' and 'sparc64' are different canonical names, because code for
dnl   'sparc' and code for 'sparc64' cannot be linked together: 'sparc' code
dnl   contains 32-bit instructions, whereas 'sparc64' code contains 64-bit
dnl   instructions. A process on a SPARC CPU can be in 32-bit mode or in 64-bit
dnl   mode, but not both.
dnl * 'mips' and 'mipsn32' are different canonical names, because they use
dnl   different argument passing and return conventions for C functions, and
dnl   although the instruction set of 'mips' is a large subset of the
dnl   instruction set of 'mipsn32'.
dnl * 'mipsn32' and 'mips64' are different canonical names, because they use
dnl   different sizes for the C types like 'int' and 'void *', and although
dnl   the instruction sets of 'mipsn32' and 'mips64' are the same.
dnl * 'arm' and 'armel' are different canonical names, because they use
dnl   different memory ordering for the C types like 'int', and although
dnl   the instruction sets of 'arm' and 'armel' are the same.
dnl * The same name 'i386' is used for CPUs of type i386, i486, i586
dnl   (Pentium), AMD K7, Pentium II, Pentium IV, etc., because
dnl   - Instructions that do not exist on all of these CPUs (cmpxchg,
dnl     MMX, SSE, SSE2, 3DNow! etc.) are not frequently used. If your
dnl     assembly language source files use such instructions, you will
dnl     need to make the distinction.
dnl   - Speed of execution of the common instruction set is reasonable across
dnl     the entire family of CPUs. If you have assembly language source files
dnl     that are optimized for particular CPU types (like GNU gmp has), you
dnl     will need to make the distinction.
