That's looking much better :) And finally, how many failures do you get running the same test under QEMU 3.1? If that gives you zero failures then I'll need to look a lot closer at the changes to try and figure out what is going on.
As a matter of interest, which tests are the ones that are failing? -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1841990 Title: instruction 'denbcdq' misbehaving Status in QEMU: New Bug description: Instruction 'denbcdq' appears to have no effect.

Could be related to endianness? I think denbcdq arrived on the scene before little-endian was a big deal. Maybe something to do with utilizing implicit floating-point register pairs... I don't think the right data is getting to helper_denbcdq, which would point back to the gen_fprp_ptr uses in dfp-impl.inc.c (GEN_DFP_T_FPR_I32_Rc). (Maybe?)
