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 mpir.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.
