Bug #76429 [NEW]: zend_accelerator_util_funcs.c error: unknown register name ‘%ymm0’ in ‘asm

From: eva2000 at centminmod dot com Operating system: centos 7.5 PHP version: 7.3.0alpha1 Package: opcache Bug Type: Bug Bug description:zend_accelerator_util_funcs.c error: unknown register name ‘%ymm0’ in ‘asm Description: ------------ Test source compile of PHP 7.3.0alpha1 results in failure at opcache section but only on Intel Xeon Gold Skylake server with CentOS 7.5 64bit (running in Ubuntu 18.04 LTS with LXD 3.1 based CentOS 7.5 container https://github.com/centminmod/centminmod-lxd). PHP 7.3.0alpha + Zend Opcache successfully compiles on Xeon E3-1270v1 Sandybridge system though.
