--- Comment #5 from Julian Seward <jsew...@acm.org> --- Mark, I think the patch is OK. In these insns we have, redundantly: REX.W=1, which says that this insn is 64-bits wide w.r.t. how it interacts with the integer register set, which is irrelevant because it doesn't interact with the integer register set at all, apart from the (%r8) address, for which REX.W isn't relevant, and REX.B=1, which supplies the "extra" (4th) register-number bit for some 3rd register field which the insn doesn't have -- there are only 2 registers mentioned. As to where these come from, I have often wondered that. I suspect it is a buggy non-GNU assembler, but really I don't know. The hardware ignores these redundant prefixes but V is stricter. Fortunately GNU as is very good about not generating them. -- You are receiving this mail because: You are watching all bug changes.
