`#pragma GCC target("+nothing+crc")` is means clear outs aarch64_isa_flags.
However, `#pragma clang attribute
push(__attribute__((target("+nothing+crc")` is not means any, then
displays ignore feature. (Not reproduce Linux on ARM (ex: Raspberry Pi))
Therefore, Compiling on M1/M2 macOS add new `#pragma`.

Does this need backporting to 8.1? |
I think master branch is enough. |
|
I may say maybe at least 8.2 what do you think ? |
Thanks for checking. I confirmed on PHP 8.2. I think good. |

There was a problem hiding this comment.
Personally I would just remove this - it doesn't make much sense - just unnecessary code duplication but it's a NIT really..

I think this should go to master only - this is not breaking build, right? |
Yes, This is not breaking build. |
|
I m good with that. |
