Bug #75300 [Opn]: SLJIT_CACHE_FLUSH: The builtin "__builtin___clear_cache" is not supported

Edit report at https://bugs.php.net/bug.php?id=75300&edit=1 ID: 75300 Updated by: pollita@php.net Reported by: kaplan@php.net Summary: SLJIT_CACHE_FLUSH: The builtin "__builtin___clear_cache" is not supported Status: Open Type: Bug Package: Compile Failure Operating System: Linux/POWER8 PHP Version: 7.2.0RC3 Block user comment: N Private report: N New Comment: 275 #if __has_builtin(__builtin___clear_cache) 276 277 #define SLJIT_CACHE_FLUSH(from, to) \ 278 __builtin___clear_cache((char*)from, (char*)to) 279 280 #endif /* __has_builtin(__builtin___clear_cache) */ Seems like a bug in whatever compiler you're using since that define is guarded by an #if __has_builtin check.
