Hello danack@
I hope that you are going good.
Please stop decide what exactly I want. It is just my bug report, not my wants. I faced with it on
Travis CI by testing on it on latest GCC/LLVM.
Thank you
Have a nice day

Supposedly we are checking this at configure time already: https://github.com/php/php-src/blob/c718970e9e48d49c19933f2e4d2cd680094be79f/configure.ac#L767-L778.
What version of Clang are you using?

The asm goto is wrapped inside a #if defined(HAVE_ASM_GOTO)
Asking a project to avoid using a construct to support a particular compiler is unlikely to get the
result you want.
You (or someone else) who cares about compiling on LLVM would be better off asking for (or even
better submitting) a patch to the build configuration to stop HAVE_ASM_GOTO being defined for the
LLVM compiler.

There are a few places with code like __asm__ goto. For example Zend/zend_operators.h:532
__asm__ goto(
"decq (%0)\n\t"
"jo %l1\n"
:
: "r"(&op1->value)
: "cc", "memory"
: overflow);
return;
Please avoid using 'asm goto' as it not supported by LLVM.
