 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.
