Wed Jan 21 18:00:22 1998 Andrew Cagney <cagney@b1.cygnus.com>
* gen-semantics.c (print_semantic_body): Use GPR_SET to zero
hardwired register.
Wed Dec 17 14:49:03 1997 Jeffrey A Law (law@cygnus.com)
* gen-semantics.c (print_semantic_body): Fix handling of
hardwired zero register.
Tue Dec 9 12:45:00 1997 Andrew Cagney <cagney@b1.cygnus.com>
* igen.h (struct _igen_gen_options): Add member default_model.
* igen.c (gen_run_c): Default to the first machine in the
multi-sim list.
(main): Add MODEL parameter to gen-multi-sim option.
* gen.h (function_decl_type): Declare enum.
* gen-engine.c (print_engine_run_function_header), gen-engine.h:
Make global, pass function_decl_type as argument.
(gen_engine_h, gen_engine_c): Update call.
* gen-idecode.c (print_idecode_issue_function_header),
gen-idecode.h: Pass function_decl_type as argument.
* igen.c (gen_idecode_h): For multi-sim, delcare global variable
idecode_issue.
* igen.c (gen_run_c): For multi-sim, initialize globals
idecode_issue and engine_run.
Fri Nov 14 10:51:44 1997 Andrew Cagney <cagney@b1.cygnus.com>
* ld-insn.c (parse_insn_model_record): Allow multiple model names
to be specified in a single instruction model record.
(dump_insn_model_entry): Update.
* ld-insn.h (struct _insn_model_entry): Replace member name with
the filter names. Document syntax change.
Wed Nov 12 15:45:40 1997 Andrew Cagney <cagney@b1.cygnus.com>
* gen-engine.c (print_run_body): Add hooks for adding code before
and after an instruction has been issued.
