for the record, Darwin bootstraps OK with the change (which is to be expected, since the preferred setting for it is -fno-common). Testsuite fails are order “a few hundred” mostly seem to be related to tree-prof and vector tests (plus the anticipated scan-asm stuff, where code-gen will have changed). I don’t have cycles to analyse the causes right now - but that gives an idea. cheers Iain
