Please make it run-time selectable, aggregating all the workarounds for the R10000 under -mfix-r10000, similarly to how it is done for other silicon errata. You probably want it on by default for -march=r10000 (but not necessarily -march=r12000). You need to supply a suitable documentation update too. Maciej |
