Did you notice the bit in the GCC 4.9 release notes about LTO with Firefox?
https://gcc.gnu.org/gcc-4.9/changes.html With LTO enabled, they remarked: "Memory usage building Firefox with debug enabled was reduced from 15GB to 3.5GB; link time from 1700 seconds to 350 seconds." ... Does this mean you can now enable LTO, if you haven't already? (I guess you turned it off so far because of the mildly ridiculous compute requirements). That might yield substantial binary size reduction, which would be nice...
