- # 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.
