I found these in sim/m32r/decodex.c
unsigned int val = (((insn >> -8) & (3 << 0)));
unsigned int val = (((insn >> -12) & (1 << 0)));
Someone want to fess up?

I'm not sure there is any fessing to do. Has this file been regenerated lately? There was a bug in decoder generation that generated negative shifts which I thought we'd fixed.

FWIW, working on sim/m32r may be a short-lived pleasure, if the target-obsoleting eagerness of gdb guys ends up getting that target removed. You're welcome to work in sid land. :-) - FChE [-- Attachment #2: Type: application/pgp-signature, Size: 189 bytes --] ^ permalink raw reply [flat|nested] 3+ messages in thread
