start-sanitize-v850e
Wed Sep 17 14:02:10 1997 Andrew Cagney <cagney@b1.cygnus.com>
* simops.c: Move "ctret", "bsw", "hsw" to v850.igen, fix tracing.
(trace_module): Global, save component/module name across insn.
* simops.c: Move "bsh" to v850.igen, fix.
* v850.igen (callt): Load correct number of bytes. Fix tracing.
(stsr, ldsr): Correct src, dest fields. Fix tracing.
(ctret): Force alignment. Fix tracing.
end-sanitize-v850e
Tue Sep 16 22:14:01 1997 Andrew Cagney <cagney@b1.cygnus.com>
* simops.c (trace_output): Add result argument.
