How do you configure your builds? Perhaps your cross-builds exclude C++? I found that this (r14-383) broke MMIX building libstdc++-v3 from that commit up to and including r14-3180. See commit r14-3187. Thankfully there was just one single gotcha. I temporarily reverted the LRA change for MMIX so that I can get honest repeatable baseline results. There seems to have been one test-case regressing from the LRA switch (PR53948), thus I re-enabled LRA for MMIX again. Sorry for the late reaction. brgds, H-P
