genppctests.py
- Fix incorrect bits for some floating-point instruction opcodes or fields.
- Use separate register for FP results like DolphinPPCTests does.
- Remove extra FMULS.
- Use a regular expression for parsing ppcfloattest.txt. Don't parse the values, just put them in the output ppcloattests.csv file.
ppcfloattest.txt
- Clear crf0 and crf7 because we only care about crf1.
- Use values from DolphinPPCTests (0.0, 0.5, 1.0, 3.5, DBL_MAX, FLT_MAX, 2.4679999352, 4.9359998704, etc.). Some of the values were rounded. This will un-round them. Specify snan or qnan instead of nan.
- One of the FCMPO and FCMPU tests had qnan instead of snan input values.
ppcfloattest.csv
- Regenerate this file using the updated genppctests.py which uses the updated ppcfloattest.txt.
ppctests
- Update double_from_string to be able to parse the new values (snan, qnan, FLT_MAX, DBL_MAX).
