Bug ID: 2787
Summary: Incorrect bitness detection for JIT on AIX with newer
xlc compilers.
Product: PCRE
Version: 10.37 (PCRE2)
Hardware: Other
OS: AIX
Status: NEW
Severity: bug
Priority: medium
Component: Code
Assignee: Philip.Hazel@???
Reporter: osubboti@???
CC: pcre-dev@???
The XL C compiler's _ARCH_* macros are based on the -qarch setting and
do not necessarily imply the object mode. In particular the _ARCH_PPC64
macro only indicates that the compiler is targeted to run on a Power
processor with 64-bit support. The __64BIT__ macro is needed to detect
that the compiler is actually in 64bit mode.
The fix is:
