Hi Hans-Peter,
Hi Nick. Deja-vu here, but this time sim. I'm a bit worried
now: what is going wrong with my replies to your patches?
I don't know - I am just not seeing them. I have checked my junk logs
and they are not in there.
/tmp/hpautotest-sim/src/sim/v850/v850.igen:4177: warning: v850e3v5.63.16.0: C.vadd.h was not uniquely decoded
/tmp/hpautotest-sim/src/sim/v850/v850.igen:1538: warning: v850e3v5.63.16.0: IX.sasf decodes to the same entry
Sorry about that - I forgot to update the v850-dc file.
I am checking in the attached patch to fix this. (It also fixes all the
compile time warnings that I was seeing, so the v850 sim sources should
compile cleanly now).
Cheers
Nick
sim/v850/ChangeLog
2015-02-27 Nick Clifton <nickc@redhat.com>
* sim-main.h (reg64_t): New type.
(v850_regs): Add selID_sregs field.
(VR, SAT16, SAT32, ABS16, ABS32 ): New macros.
* v850-dc: Add fields for v850e3v5 instructions.
* v850.igen (cvtf.dl): Use correctly signed local value.
(cvtf.dw, cvtf.sw, trncf.dul, trncf.dl, trncf.sul, trncf.sw):
Likewise.
* interp.c: Fix old style function declarations.
* simops.c: Likewise.
