67 dnl Automake "no-dependencies" is used because include file dependencies
68 dnl are not useful to us. Pretty much everything depends just on gmp.h,
69 dnl gmp-impl.h and longlong.h, and yet only rarely does everything need to
70 dnl be rebuilt for changes to those files.
72 dnl "no-dependencies" also helps with the way we're setup to run
73 dnl AC_PROG_CXX only conditionally. If dependencies are used then recent
74 dnl automake (eg 1.7.2) appends an AM_CONDITIONAL to AC_PROG_CXX, and then
75 dnl gets upset if it's not actually executed.
77 dnl Note that there's a copy of these options in the top-level Makefile.am,
78 dnl so update there too if changing anything.

339 # Table of compilers, options, and mpn paths. This code has various related
342 # - better default CC/CFLAGS selections than autoconf otherwise gives
343 # - default CC/CFLAGS selections for extra CPU types specific to GMP
344 # - a few tests for known bad compilers
345 # - choice of ABIs on suitable systems
346 # - selection of corresponding mpn search path
348 # After GMP specific searches and tests, the standard autoconf AC_PROG_CC is
349 # called. User selections of CC etc are respected.
351 # Care is taken not to use macros like AC_TRY_COMPILE during the GMP
352 # pre-testing, since they of course depend on AC_PROG_CC, and also some of
353 # them cache their results, which is not wanted.
355 # The ABI selection mechanism is unique to GMP. All that reaches autoconf
356 # is a different selection of CC/CFLAGS according to the best ABI the system
357 # supports, and/or what the user selects. Naturally the mpn assembler code
358 # selected is very dependent on the ABI.
360 # The closest the standard tools come to a notion of ABI is something like
361 # "sparc64" which encodes a CPU and an ABI together. This doesn't seem to
362 # scale well for GMP, where exact CPU types like "ultrasparc2" are wanted,
363 # separate from the ABI used on them.
366 # The variables set here are
368 # cclist the compiler choices
369 # xx_cflags flags for compiler xx
370 # xx_cflags_maybe flags for compiler xx, if they work
371 # xx_cppflags cpp flags for compiler xx
372 # xx_cflags_optlist list of sets of optional flags
373 # xx_cflags_yyy set yyy of optional flags for compiler xx
374 # xx_ldflags -Wc,-foo flags for libtool linking with compiler xx

379 # extra_functions extra mpn functions
380 # fat_path fat binary mpn search path [if fat binary desired]
381 # fat_functions fat functions
382 # fat_thresholds fat thresholds
384 # Suppose xx_cflags_optlist="arch", then flags from $xx_cflags_arch are
385 # tried, and the first flag that works will be used. An optlist like "arch
386 # cpu optimize" can be used to get multiple independent sets of flags tried.
387 # The first that works from each will be used. If no flag in a set works
388 # then nothing from that set is added.
390 # For multiple ABIs, the scheme extends as follows.
392 # abilist set of ABI choices
393 # cclist_aa compiler choices in ABI aa
394 # xx_aa_cflags flags for xx in ABI aa
395 # xx_aa_cflags_maybe flags for xx in ABI aa, if they work

402 # limb_aa limb size in ABI aa, can be "longlong"
403 # path_aa mpn search path in ABI aa
404 # extra_functions_aa extra mpn functions in ABI aa
406 # As a convenience, the unadorned xx_cflags (etc) are used for the last ABI
407 # in ablist, if an xx_aa_cflags for that ABI isn't given. For example if
408 # abilist="64 32" then $cc_64_cflags will be used for the 64-bit ABI, but
409 # for the 32-bit either $cc_32_cflags or $cc_cflags is used, whichever is
410 # defined. This makes it easy to add some 64-bit compilers and flags to an
411 # unadorned 32-bit set.
413 # limb=longlong (or limb_aa=longlong) applies to all compilers within that
414 # ABI. It won't work to have some needing long long and some not, since a
415 # single instantiated gmp.h will be used by both.
417 # SPEED_CYCLECOUNTER, cyclecounter_size and CALLING_CONVENTIONS_OBJS are
418 # also set here, with an ABI suffix.
422 # A table-driven approach like this to mapping cpu type to good compiler
423 # options is a bit of a maintenance burden, but there's not much uniformity
424 # between options specifications on different compilers. Some sort of
425 # separately updatable tool might be cute.
427 # The use of lots of variables like this, direct and indirect, tends to
428 # obscure when and how various things are done, but unfortunately it's
429 # pretty much the only way. If shell subroutines were portable then actual
430 # code like "if this .. do that" could be written, but attempting the same
