# Table of compilers, options, and mpn paths. This code has various related
# purposes
#
# - better default CC/CFLAGS selections than autoconf otherwise gives
# - default CC/CFLAGS selections for extra CPU types specific to GMP
# - a few tests for known bad compilers
# - choice of ABIs on suitable systems
# - selection of corresponding mpn search path
#
# After GMP specific searches and tests, the standard autoconf AC_PROG_CC is
# called. User selections of CC etc are respected.
#
# Care is taken not to use macros like AC_TRY_COMPILE during the GMP
# pre-testing, since they of course depend on AC_PROG_CC, and also some of
# them cache their results, which is not wanted.
#
# The ABI selection mechanism is unique to GMP. All that reaches autoconf
# is a different selection of CC/CFLAGS according to the best ABI the system
# supports, and/or what the user selects. Naturally the mpn assembler code
# selected is very dependent on the ABI.
#
# The closest the standard tools come to a notion of ABI is something like
# "sparc64" which encodes a CPU and an ABI together. This doesn't seem to
# scale well for GMP, where exact CPU types like "ultrasparc2" are wanted,
# separate from the ABI used on them.
#
#
# The variables set here are
#
# cclist the compiler choices
# xx_cflags flags for compiler xx
# xx_cflags_maybe flags for compiler xx, if they work
# xx_cppflags cpp flags for compiler xx
# xx_cflags_optlist list of sets of optional flags
# xx_cflags_yyy set yyy of optional flags for compiler xx
# xx_ldflags -Wc,-foo flags for libtool linking with compiler xx
# ar_flags extra flags for $AR
# nm_flags extra flags for $NM
# limb limb size, can be "longlong"
# path mpn search path
# extra_functions extra mpn functions
# fat_path fat binary mpn search path [if fat binary desired]
# fat_functions fat functions
# fat_thresholds fat thresholds
#
# Suppose xx_cflags_optlist="arch", then flags from $xx_cflags_arch are
# tried, and the first flag that works will be used. An optlist like "arch
# cpu optimize" can be used to get multiple independent sets of flags tried.
# The first that works from each will be used. If no flag in a set works
# then nothing from that set is added.
#
# For multiple ABIs, the scheme extends as follows.
#
# abilist set of ABI choices
# cclist_aa compiler choices in ABI aa
# xx_aa_cflags flags for xx in ABI aa
# xx_aa_cflags_maybe flags for xx in ABI aa, if they work
# xx_aa_cppflags cpp flags for xx in ABI aa
# xx_aa_cflags_optlist list of sets of optional flags in ABI aa
# xx_aa_cflags_yyy set yyy of optional flags for compiler xx in ABI aa
# xx_aa_ldflags -Wc,-foo flags for libtool linking
# ar_aa_flags extra flags for $AR in ABI aa
# nm_aa_flags extra flags for $NM in ABI aa
# limb_aa limb size in ABI aa, can be "longlong"
# path_aa mpn search path in ABI aa
# extra_functions_aa extra mpn functions in ABI aa
#
# As a convenience, the unadorned xx_cflags (etc) are used for the last ABI
# in ablist, if an xx_aa_cflags for that ABI isn't given. For example if
# abilist="64 32" then $cc_64_cflags will be used for the 64-bit ABI, but
# for the 32-bit either $cc_32_cflags or $cc_cflags is used, whichever is
# defined. This makes it easy to add some 64-bit compilers and flags to an
# unadorned 32-bit set.
#
# limb=longlong (or limb_aa=longlong) applies to all compilers within that
# ABI. It won't work to have some needing long long and some not, since a
# single instantiated gmp.h will be used by both.
#
# SPEED_CYCLECOUNTER, cyclecounter_size and CALLING_CONVENTIONS_OBJS are
# also set here, with an ABI suffix.
#
#
#
# A table-driven approach like this to mapping cpu type to good compiler
# options is a bit of a maintenance burden, but there's not much uniformity
# between options specifications on different compilers. Some sort of
# separately updatable tool might be cute.
#
# The use of lots of variables like this, direct and indirect, tends to
# obscure when and how various things are done, but unfortunately it's
# pretty much the only way. If shell subroutines were portable then actual
# code like "if this .. do that" could be written, but attempting the same
# with full copies of GMP_PROG_CC_WORKS etc expanded at every point would
# hugely bloat the output.
# abilist needs to be non-empty, "standard" is just a generic name here

# FIXME: We'd like to prefer an ANSI compiler, perhaps by preferring
# c89 over cc here. But note that on HP-UX c89 provides a castrated
# environment, and would want to be excluded somehow. Maybe

# we don't need to worry.
