dnl GMP_PROG_AR
dnl -----------
dnl GMP additions to $AR.
dnl
dnl A cross-"ar" may be necessary when cross-compiling since the build
dnl system "ar" might try to interpret the object files to build a symbol
dnl table index, hence the use of AC_CHECK_TOOL.
dnl
dnl A user-selected $AR is always left unchanged. AC_CHECK_TOOL is still
dnl run to get the "checking" message printed though.
dnl
dnl $AR_FLAGS is set to "cq" rather than leaving it to libtool "cru". The
dnl latter fails when libtool goes into piecewise mode and is unlucky
dnl enough to have two same-named objects in separate pieces, as happens
dnl for instance to random.o (and others) on vax-dec-ultrix4.5. Naturally
dnl a user-selected $AR_FLAGS is left unchanged.

dnl
dnl For a native build, meaning $cross_compiling == no, we require that the

dnl a CC/CFLAGS combination that it rejects.
dnl
dnl sparc-*-solaris2.7 can compile ABI=64 but won't run it if the kernel

dnl GMP_ASM_X86_MCOUNT
dnl ------------------
dnl Find out how to call mcount for profiling on an x86 system.
dnl
dnl A dummy function is compiled and the ".s" output examined. The pattern
dnl matching might be a bit fragile, but should work at least with gcc on
dnl sensible systems. Certainly it's better than hard coding a table of
dnl conventions.
dnl
dnl For non-PIC, any ".data" is taken to mean a counter might be passed.
dnl It's assumed a movl will set it up, and the right register is taken
dnl from that movl. Any movl involving %esp is ignored (a frame pointer
dnl setup normally).
dnl
dnl For PIC, any ".data" is similarly interpreted, but a GOTOFF identifies
dnl the line setting up the right register.
dnl
dnl In both cases a line with "mcount" identifies the call and that line is
dnl used literally.
dnl
dnl On some systems (eg. FreeBSD 3.5) gcc emits ".data" but doesn't use it,
dnl so it's not an error to have .data but then not find a register.
dnl
dnl Variations in mcount conventions on different x86 systems can be found
dnl in gcc config/i386. mcount can have a "_" prefix or be .mcount or
dnl _mcount_ptr, and for PIC it can be called through a GOT entry, or via
dnl the PLT. If a pointer to a counter is required it's passed in %eax or
dnl %edx.
dnl
dnl Flags to specify PIC are taken from $lt_prog_compiler_pic set by
dnl AC_PROG_LIBTOOL.
dnl
dnl Enhancement: Cache the values determined here. But what's the right way
dnl to get two variables (mcount_nonpic_reg and mcount_nonpic_call say) set

dnl
dnl BITS_PER_MP_LIMB, BYTES_PER_MP_LIMB and BITS_PER_ULONG are needed at

dnl conditionals.
dnl
dnl BITS_PER_MP_LIMB is also wanted as a plain constant for some macros in
dnl the generated gmp.h, and is instantiated as BITS_PER_MP_LIMB.
dnl
dnl If some assembler code depends on a particular type size it's probably
dnl best to put explicit #defines for these in gmp-mparam.h. That way if
dnl strange compiler options change the size then a mismatch will be
dnl detected by t-constants.c rather than only by the code crashing or
dnl giving wrong results.
dnl
dnl None of the assembler code depends on BITS_PER_ULONG currently, so it's
dnl just as easy to let configure find its size as to put explicit values.
dnl
dnl The tests here assume bits=8*sizeof, but that might not be universally
dnl true. It'd be better to probe for how many bits seem to work, like
dnl t-constants does. But all currently supported systems have limbs and
dnl ulongs with bits=8*sizeof, so it's academic. Strange systems can
dnl always have the right values put in gmp-mparam.h explicitly.

# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory. The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run. This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
# fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
# fails if $ac_aux_dir is absolute,
# fails when called from a subdirectory in a VPATH build with
# a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir. In an in-source build this is usually
# harmless because $srcdir is `.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
# MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.

# absolute PATH. The drawback is that using absolute paths prevent a
