When including 2754dnl configuration header, warnings about redefined symbols are emitted for such 2755dnl symbols if they are defined by multiple libraries. This disables all 2756dnl PACKAGE_* symbols in the generated configuration header template FILE. For 2757dnl example, main/php_config.h.in for PHP or config.h.in for PHP extensions. 2758dnl 2759AC_DEFUN([PHP_PATCH_CONFIG_HEADERS], [ 2760 AC_MSG_NOTICE([patching $1]) 2761 2762 $SED -e 's/^#undef PACKAGE_[^ ]*/\/\* & \*\//g' < $srcdir/$1 \ 2763 > $srcdir/$1.tmp && mv $srcdir/$1.tmp $srcdir/$1 2764]) 2765 2766dnl 2767dnl PHP_CHECK_AVX512_SUPPORTS 2768dnl 2769AC_DEFUN([PHP_CHECK_AVX512_SUPPORTS], [ 2770 AC_MSG_CHECKING([for avx512 supports in compiler]) 2771 save_CFLAGS="$CFLAGS" 2772 CFLAGS="-mavx512f -mavx512cd -mavx512vl -mavx512dq -mavx512bw $CFLAGS" 2773 2774 AC_LINK_IFELSE([AC_LANG_SOURCE([[ 2775 #include <immintrin.h> 2776 int main(void) { 2777 __m512i mask = _mm512_set1_epi32(0x1); 2778 char out[32]; 2779 _mm512_storeu_si512(out, _mm512_shuffle_epi8(mask, mask)); 2780 return 0; 2781 }]])], [ 2782 have_avx512_supports=1 2783 AC_MSG_RESULT([yes]) 2784 ], [ 2785 have_avx512_supports=0 2786 AC_MSG_RESULT([no]) 2787 ]) 2788 2789 CFLAGS="$save_CFLAGS" 2790 2791 AC_DEFINE_UNQUOTED([PHP_HAVE_AVX512_SUPPORTS], 2792 [$have_avx512_supports], [Whether the compiler supports AVX512]) 2793]) 2794 2795dnl 2796dnl PHP_CHECK_AVX512_VBMI_SUPPORTS 2797dnl 2798AC_DEFUN([PHP_CHECK_AVX512_VBMI_SUPPORTS], [ 2799 AC_MSG_CHECKING([for avx512 vbmi supports in compiler]) 2800 save_CFLAGS="$CFLAGS" 2801 CFLAGS="-mavx512f -mavx512cd -mavx512vl -mavx512dq -mavx512bw -mavx512vbmi $CFLAGS" 2802 AC_LINK_IFELSE([AC_LANG_SOURCE([[ 2803 #include <immintrin.h> 2804 int main(void) { 2805 __m512i mask = _mm512_set1_epi32(0x1); 2806 char out[32]; 2807 _mm512_storeu_si512(out, _mm512_permutexvar_epi8(mask, mask)); 2808 return 0; 2809 }]])], [ 2810 have_avx512_vbmi_supports=1 2811 AC_MSG_RESULT([yes]) 2812 ], [ 2813 have_avx512_vbmi_supports=0 2814 AC_MSG_RESULT([no]) 2815 ]) 2816 CFLAGS="$save_CFLAGS" 2817 AC_DEFINE_UNQUOTED([PHP_HAVE_AVX512_VBMI_SUPPORTS], 2818 [$have_avx512_vbmi_supports], [Whether the compiler supports AVX512 VBMI]) 2819]) 2820 2821dnl 2822dnl PHP_CHECK_VARIABLE_ATTRIBUTE(attribute) 2823dnl 2824dnl Check whether the compiler supports the GNU C variable attribute. 2825dnl 2826AC_DEFUN([PHP_CHECK_VARIABLE_ATTRIBUTE], 2827[AS_VAR_PUSHDEF([php_var], [php_cv_have_variable_attribute_$1]) 2828AC_CACHE_CHECK([for variable __attribute__(($1))], [php_var], 2829[AC_COMPILE_IFELSE([AC_LANG_PROGRAM([m4_case([$1], 2830 [aligned], 2831 [unsigned char test[32] __attribute__(($1(__alignof__(int))));], 2832 [ 2833 m4_warn([syntax], [Unsupported variable attribute $1, the test may fail]) 2834 int var __attribute__(($1)); 2835 ])], 2836 [])], 2837dnl By default, compilers may not classify attribute warnings as errors 2838dnl (-Werror=attributes) when encountering an unknown attribute.
