That fixed all the *-elf regressions in my tester (arc, nds32be, v850e, mn10300, msp430, nds32le, lm3, visium, or1k, cris, iq2000, fr30, m32r, mcore, crisv32 all flagged it as a regression).
I suspect it'll fix the regressions on with sparc64, aarch64 & s390x native linux since they all regressed just the sinatan test. The powerpc64 and powerpc64le platforms continue to have all kinds of problems. The amount of instability from day to day is concerning. jeff
