Contrary to other instructions where if you use REX + high bit offsets then it'll pull in rsp and a few other registers. -On hardware the REX prefix doesn't effect behaviour of these instructions at all. -QEMU incorrectly selects RSP as the register of choice here due to this combination of REX + AH register usage. - -I've attached a patch that is super terrible just so I can work around the issue locally and to sort of show off how it is to be "fixed" \ No newline at end of file |
