# 09a36812	22-Mar-2024	Remi Collet	Fix AX_GCC_FUNC_ATTRIBUTE failure
# 0a47fdf5	03-Jun-2022	David Carlier	Revert "Fix detection of unknown gcc function attributes" This reverts commit 813d942bac2b604bb7f6b80aefac6e4aa69b3491.
# 813d942b	02-May-2022	Athos Ribeiro	Fix detection of unknown gcc function attributes As described in autoconf-archive upstream [1], from where `build/ax_gcc_func_attribute.m4` is forked, the old unknown func attr detec Fix detection of unknown gcc function attributes As described in autoconf-archive upstream [1], from where `build/ax_gcc_func_attribute.m4` is forked, the old unknown func attr detection method would throw a false negative anytime an unrelated warning was raised. This results in `ax_cv_have_func_attribute_target` being set to `no` whenever certain compiler Warning flags are switched on. Namely, having `-Wall` on, which is a default CFLAG for some linux distributions, will result in ``` warning: ‘bar’ declared ‘static’ but never defined [-Wunused-function] ``` when evaluating support for the `target` function attribute. With that configuration value set to `no`, the compiled php binaries will not support x86_64 v3 instructions such as avx2 and sse2, which should speed up specific tasks ran by PHP. This issue was originally reported in Ubuntu [2].
