PATCH 1/1 gcc: Add GCC 5.2.x option
Cyril,
Quoted 9 lines · Cyril Bur
GCC 5.3.x introduces a regression with PowerPC Altivec/VSX code generation.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69969
Signed-off-by Cyril Bur <[email protected]>---
I'm not sure if this patch is worth the trouble. By the looks of it the GCC guys are aiming to have a fix in 5.4 and it is unlikely most users are doing things that would result in them hitting the bug.
Like we did for previous gcc versions, we only want to support one minor version at a time for a given major branch.
So at the gcc 4 era, it meant we would only package one gcc 4.8, one gcc 4.9, etc.
At the gcc >= 5 era, it means we want to package only one 5.x version, one 6.x version, etc.
If you want to fix the problem without waiting for gcc 5.4, what I can suggest is to backport the fixes for the regression you are experiencing.

No fix exists yet but yeah upstreaming this patch is definitely more headache in the long run, I just thought I'd put it out here - it's probably the easiest fix to this problem (for now) so in the unlikely event that anyone else hits it, hopefully they'll find this.
Thanks for the response,
Cyril
