965122 - Build and deploy a patched gcc 4.7.3

Status: RESOLVED FIXED

(Infrastructure & Operations Graveyard :: CIDuty, task)

Description

[Mike Hommey [:glandium]]

Bug 964641 has unveiled a sneaky bug in GCC that affects PGO only, only in some circumstances. While the bug can be circumvented with the patch in that bug, it would be better to have a patched gcc avoiding this bug altogether, in case it would show up again somewhere else.
