They have different -dnl instruction sets. -dnl * 'sparc' and 'sparc64' are different canonical names, because code for -dnl 'sparc' and code for 'sparc64' cannot be linked together: 'sparc' code -dnl contains 32-bit instructions, whereas 'sparc64' code contains 64-bit -dnl instructions. A process on a SPARC CPU can be in 32-bit mode or in 64-bit -dnl mode, but not both. -dnl * 'mips' and 'mipsn32' are different canonical names, because they use -dnl different argument passing and return conventions for C functions, and -dnl although the instruction set of 'mips' is a large subset of the -dnl instruction set of 'mipsn32'. -dnl * 'mipsn32' and 'mips64' are different canonical names, because they use -dnl different sizes for the C types like 'int' and 'void *', and although -dnl the instruction sets of 'mipsn32' and 'mips64' are the same. -dnl * The same canonical name is used for different endiannesses. You can -dnl determine the endianness through preprocessor symbols: -dnl - 'arm': test __ARMEL__. -dnl - 'mips', 'mipsn32', 'mips64': test _MIPSEB vs. _MIPSEL. -dnl - 'powerpc64': test _BIG_ENDIAN vs. _LITTLE_ENDIAN. -dnl * The same name 'i386' is used for CPUs of type i386, i486, i586 -dnl (Pentium), AMD K7, Pentium II, Pentium IV, etc., because -dnl - Instructions that do not exist on all of these CPUs (cmpxchg, -dnl MMX, SSE, SSE2, 3DNow! etc.) are not frequently used. If your -dnl assembly language source files use such instructions, you will -dnl need to make the distinction. -dnl - Speed of execution of the common instruction set is reasonable across -dnl the entire family of CPUs. If you have assembly language source files -dnl that are optimized for particular CPU types (like GNU gmp has), you -dnl will need to make the distinction. -dnl See <https://en.wikipedia.org/wiki/X86_instruction_listings>. -AC_DEFUN([gl_HOST_CPU_C_ABI], -[ - AC_REQUIRE([AC_CANONICAL_HOST]) - AC_REQUIRE([gl_C_ASM]) - AC_CACHE_CHECK([host CPU and C ABI], [gl_cv_host_cpu_c_abi], - [case "$host_cpu" in - -changequote(,)dnl - i[34567]86 ) -changequote([,])dnl - gl_cv_host_cpu_c_abi=i386 - ;; - - x86_64 ) - # On x86_64 systems, the C compiler may be generating code in one of - # these ABIs: - # - 64-bit instruction set, 64-bit pointers, 64-bit 'long': x86_64. - # - 64-bit instruction set, 64-bit pointers, 32-bit 'long': x86_64 - # with native Windows (mingw, MSVC). - # - 64-bit instruction set, 32-bit pointers, 32-bit 'long': x86_64-x32. - # - 32-bit instruction set, 32-bit pointers, 32-bit 'long': i386. - AC_COMPILE_IFELSE( - [AC_LANG_SOURCE( - [[#if (defined __x86_64__ || defined __amd64__ \ - || defined _M_X64 || defined _M_AMD64) - int ok; - #else - error fail - #endif - ]])], - [AC_COMPILE_IFELSE( - [AC_LANG_SOURCE( - [[#if defined __ILP32__ || defined _ILP32 - int ok; - #else - error fail - #endif - ]])], - [gl_cv_host_cpu_c_abi=x86_64-x32], - [gl_cv_host_cpu_c_abi=x86_64])], - [gl_cv_host_cpu_c_abi=i386]) - ;; - -changequote(,)dnl - alphaev[4-8] | alphaev56 | alphapca5[67] | alphaev6[78] ) -changequote([,])dnl - gl_cv_host_cpu_c_abi=alpha - ;; - - arm* | aarch64 ) - # Assume arm with EABI. - # On arm64 systems, the C compiler may be generating code in one of - # these ABIs: - # - aarch64 instruction set, 64-bit pointers, 64-bit 'long': arm64. - # - aarch64 instruction set, 32-bit pointers, 32-bit 'long': arm64-ilp32. - # - 32-bit instruction set, 32-bit pointers, 32-bit 'long': arm or armhf. - AC_COMPILE_IFELSE( - [AC_LANG_SOURCE( - [[#ifdef __aarch64__ - int ok; - #else - error fail - #endif - ]])], - [AC_COMPILE_IFELSE( - [AC_LANG_SOURCE( - [[#if defined __ILP32__ || defined _ILP32 - int ok; - #else - error fail - #endif - ]])], - [gl_cv_host_cpu_c_abi=arm64-ilp32], - [gl_cv_host_cpu_c_abi=arm64])], - [# Don't distinguish little-endian and big-endian arm, since they - # don't require different machine code for simple operations and - # since the user can distinguish them through the preprocessor - # defines __ARMEL__ vs. __ARMEB__. - # But distinguish arm which passes floating-point arguments and - # return values in integer registers (r0, r1, ...) - this is - # gcc -mfloat-abi=soft or gcc -mfloat-abi=softfp - from arm which - # passes them in float registers (s0, s1, ...) and double registers - # (d0, d1, ...) - this is gcc -mfloat-abi=hard.
