Hi all,
I am running a code using the x86 decoder and I have just noticed that
for "addss", "mulss", and "divss" the instructions type which is
detected by gem5 is FloatAdd (instead of FloatMul and FloatDiv for mulss
and divss). I attach an example from the debug output:
28189782: system.cpu T0 : @foo+189.0 : DIVSS_XMM_XMM : mdivf
%xmm1_low, %xmm1_low, %xmm0_low : FloatAdd : D=0x000000003faf983c
To me this looks like a bug which is quite important to fix. I have been
trying to do it though, but with no results yet. Does someone have any
clue how this can be fixed or if there is any existent patch already? I
read the documentation in gem5
(http://www.m5sim.org/X86_Instruction_decoding) about the x86
instruction decode, but it does not quite clarify the code...
So, any ideas?
Regards,
Ferran O.
