> The patch also includes the X87 instructions which were missing in previous patch commit r307529 as reported in bugzilla bug 34080.
Just to be clear, this doesn't fix PR34080, it just reschedules the codegen but still doesn't enforce the x86 cw barriers that we need - but then this is a scheduler so all its done is expose the issue, not caused it.
