--- Comment #32 from Richard Biener <rguenth at gcc dot gnu.org> ---
Yeah, to summarize:
- Using --param ggc-min-expand=100 --param ggc-min-heapsize=131072 fixes
LTO bootstrap (I tested x86_64 on the 4.9 branch)
- Using the patch from comment #26 doesn't fix LTO bootstrap but makes
build/genconfig.o no longer to miscompare
Thus we seem to have a multitude of GC-related "IL" differences. Ugh.
