This is yet another case of enabling some insns but disabling many other insns: our power10 support requires insns we enable on power9 and later only (set[n]bc[r] is a special case of isel). We should make it impossible for people to enable -mpower10 (without doing -mcpu=power10) somehow. ^ permalink raw reply [flat|nested] 5+ messages in thread
