Hi,
here is the next patchset for the TriCore ISA, which steadily moves towards
being a usable qemu guest.
This patchset first cleans up the SSOV/SUOV makros, which were only suitable
for 32 bit arithmetic,
to make room for 16bit SSOV/SUOV arithmetic used for the RR insn. These are
splitted into four patches,
seperated by the first opcode all insn of one patch have. I also added missed
1.6 insns and fixed some
minor errors. The last patch adds the first half of the RR1 insn.
Cheers,
Bastian
v1 -> v2:
- SSOV32/SUOV32 are now regular functions.
- gen_cond_w now uses neg and saves a temp.
- SSOV16/SUOV16 are now regular functions.
- Use TCG_CALL_NO_RWG_SE for all helpers not using globals.
- Use more compact code for helper_parity. (Thanks Richard!)
- Remove redundant temp creation.
- mul_h/mulm_h/mulr_h: * move arg extraction to tcg.
* compute psw flags in tcg-op now.
* helper now use TCG_CALL_NO_RWG_SE flag.
