# 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

# 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.
|

|
|
# 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

# single instantiated mpir.h will be used by both.
