Bug ID: 156337
Summary: S390X and PPC64 architectures detection is wrong
Classification: Unclassified
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: Web Template Framework
Assignee: webkit-unassigned at lists.webkit.org
Reporter: tpopela at redhat.com
After the https://bugs.webkit.org/show_bug.cgi?id=156015 was committed it showed that the PPC64 detection is wrong as on the CPU(PPC) path was activated even for PPC64. The thing is that GCC defines __ppc__ even on PPC64 and not just on PPC(32). The same applies for S390X.
$ gcc -dM -E - < /dev/null | grep PPC
#define _ARCH_PPCGR 1
#define __PPC64__ 1 <---
#define _ARCH_PPCSQ 1
#define _ARCH_PPC 1
#define __PPC__ 1 <---
#define _ARCH_PPC64 1
