Bug 653320 – x11-drivers/xf86-video-intel CFLAGS=-flto - .../work/xf86-video-intel-9999/src/sna/blt.c: In function ‘to_memcpy’: /usr/include/bits/string_fortified.h:31:1: error: inlining failed in call to always_inline ‘memcpy’: target specific option mismatch

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description n05ph3r42 2018-04-16 17:34:29 UTC]

Emerging x11-drivers/xf86-video-intel-xx with CFLAG "-flto"  causes "inlining failed in call to always_inline ‘memcpy’: target specific option mismatch" 



Reproducible: Always

Steps to Reproduce:
1. set CFLAGS to use LTO (-flto)
2. emerge x11-drivers/xf86-video-intel
3.
Actual Results:  
emake failed
"inlining failed in call to always_inline ‘memcpy’: target specific option mismatch"


Here i used 9999, but stable and unstable versions gives same result

Fedora has a hacky patch to work around this, or a similar problem:

https://src.fedoraproject.org/rpms/xorg-x11-drv-intel/blob/master/f/intel-gcc-pr65873.patch

Seems like the real bug is in GCC: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65873
