--- Comment #26 from Dominique d'Humieres <dominiq at lps dot ens.fr> 2012-01-20 16:24:34 UTC --- I have done a clean bootstrap of r183305 on powerpc-apple-darwin9 with the patch in comment #25. Regtesting in progress (allow for ~20 more hours), but gcc at -m32 has only 28 failures (including 16 for gcc.dg/simulate-thread/atomic-* instead of usually 12: I cannot say presently if it is due to some slow down due to the patch or because I am using the machine while usually it is only devoted to the test suite).
