-QEmu translation is incorrect when using REX in combination with LAHF/SAHF
-
-When translating code that is using LAHF and SAHF in combination with the REX prefix then qemu translates incorrectly.
-These two instructions only ever use the AH register. 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"
-
-
-
-Here's also a basic test that can be run on hardware and have rflags and rsp inspected after each instruction just to see how hardware doesn't effect it.
-
-The QEMU project is currently considering to move its bug tracking to
-another system. For this we need to know which bugs are still valid
-and which could be closed already. Thus we are setting older bugs to
-"Incomplete" now.
-
-If you still think this bug report here is valid, then please switch
-the state back to "New" within the next 60 days, otherwise this report
-will be marked as "Expired". Or please mark it as "Fix Released" if
-the problem has been solved with a newer version of QEMU already.
-
-Thank you and sorry for the inconvenience.
-
-This is still relevant.
-
-
-This is an automated cleanup. This bug report has been moved to QEMU's
-new bug tracker on gitlab.com and thus gets marked as 'expired' now.
-Please continue with the discussion here:
