sim/h8300/ChangeLog:
2003-07-23 Richard Sandiford <rsandifo@redhat.com> * compile.c (sim_resume): Make sure that dst.reg refers to the right register byte in mova/sz.l @(dd,RnL),ERn. 2003-07-21 Richard Sandiford <rsandifo@redhat.com> * compile.c (sim_resume): Zero-extend immediate to muls, mulsu, mulxs, divs and divxs. sim/testsuite/sim/h8300/ChangeLog: 2003-07-22 Michael Snyder <msnyder@redhat.com> * mul.s: Don't try to use negative immediate (it's always unsigned). * div.s: Ditto.
