240 # SYNOPSIS
241 #
242 # AX_GCC_ARCHFLAG([PORTABLE?], [ACTION-SUCCESS], [ACTION-FAILURE])
243 #
244 # DESCRIPTION
245 #
246 # This macro tries to guess the "native" arch corresponding to the target
247 # architecture for use with gcc's -march=arch or -mtune=arch flags. If
248 # found, the cache variable $ax_cv_gcc_archflag is set to this flag and
249 # ACTION-SUCCESS is executed; otherwise $ax_cv_gcc_archflag is is set to
250 # "unknown" and ACTION-FAILURE is executed. The default ACTION-SUCCESS is
251 # to add $ax_cv_gcc_archflag to the end of $CFLAGS.
252 #
253 # PORTABLE? should be either [yes] (default) or [no]. In the former case,
254 # the flag is set to -mtune (or equivalent) so that the architecture is
255 # only used for tuning, but the instruction set used is still portable. In
256 # the latter case, the flag is set to -march (or equivalent) so that
257 # architecture-specific instructions are enabled.
258 #
259 # The user can specify --with-gcc-arch=<arch> in order to override the
260 # macro's choice of architecture, or --without-gcc-arch to disable this.
261 #
262 # When cross-compiling, or if $CC is not gcc, then ACTION-FAILURE is
263 # called unless the user specified --with-gcc-arch manually.
264 #
265 # Requires macros: AX_CHECK_COMPILER_FLAGS, AX_GCC_X86_CPUID
266 #
267 # (The main emphasis here is on recent CPUs, on the principle that doing
268 # high-performance computing on old hardware is uncommon.)

455 # SYNOPSIS
456 #
457 # AX_GCC_X86_CPUID(OP)
458 #
459 # DESCRIPTION
460 #
461 # On Pentium and later x86 processors, with gcc or a compiler that has a
462 # compatible syntax for inline assembly instructions, run a small program
463 # that executes the cpuid instruction with input OP. This can be used to
464 # detect the CPU type.
465 #
466 # On output, the values of the eax, ebx, ecx, and edx registers are stored
467 # as hexadecimal strings as "eax:ebx:ecx:edx" in the cache variable
468 # ax_cv_gcc_x86_cpuid_OP.
469 #
470 # If the cpuid instruction fails (because you are running a
471 # cross-compiler, or because you are not using gcc, or because you are on
472 # a processor that doesn't have this instruction), ax_cv_gcc_x86_cpuid_OP
473 # is set to the string "unknown".
474 #
475 # This macro mainly exists to be used in AX_GCC_ARCHFLAG.
