I converted MSA opcodes to decodetree. To keep the series
small I split it in 2, this is the non-decodetree specific
patches (so non-decodetree experts can review it ;) ).
First we stop using env->insn_flags to check for MSAi
presence, then we restrict TCG functions to DisasContext*.
Hi Philippe,
For the whole series,
Reviewed-by: Jiaxun Yang <jiaxun.yang@xxxxxxxxxxx>
I'm just curious about how would you deal with so many condition flags
with decodetree?
Unlike other ISAs, MIPS have so many flavors, every ISA level (MIPS-III
R2 R5 R6)
has it's own instructions, and in my understanding decodetree file won't
generate
these switches. I was trying to do the same thing but soon find out
we'll have around
20 decodertree for MIPS.
Thanks.
