 libcpp/lex.c includes ../gcc/config/i386/cpuid.h, and is picked up
 by the system compiler during stage1. Recently, cpuid.h was changed to
 account for %ebx changes and now uses b asm constraint for i686 even
 with __PIC__.

Attached patch is what I have committed to mainline SVN.

[PATCH, i386]: Fix PR 63966, inconsistent operand constraints compiling libcpp

2014-11-19 Thread Uros Bizjak
Hello!

libcpp/lex.c includes ../gcc/config/i386/cpuid.h, and is picked up
by the system compiler during stage1. Recently, cpuid.h was changed to
account for %ebx changes and now uses b asm constraint for i686 even
with __PIC__.

Attached patch solves this issue by including system cpuid.h for GCC  5.0.

PR target/63966
* lex.c [__i386__ || __x86_64__]: Include system cpuid.h for
GCC_VERSION  5000.

Patch was bootstrapped on x86_64-linux-gnu, Fedora 20. Patch will be
committed to mainline in a day or two, preferably after someone tests
it on Darwin.

Uros.
