|
||||
|
||||
* igen.c (gen_run_c): New function. Generate sim_engine_run that
|
||||
looks at the currently selected architecture.
|
||||
|
||||
* gen-engine.c, gen-idecode.c: Add multi-sim support - generate
|
||||
one engine per model.
|
||||
|
||||
* gen-semantics.c, gen-icache.c gen-support.c:
|
||||
Update.
|
||||
|
||||
* ld-insn.h, ld-insn-h (load_insn_table): Rewrite. table.h only
|
||||
returns a line at a time. Parse multi-word instructions. Add
|
||||
multi-sim support.
|
||||
|
||||
* table.h, table.c: Simplify. Only parse a single line at a time.
|
||||
ld-insn can handle the rest.
|
||||
|
||||
* filter.h, filter.c (filter_parse, filter_add, filter_is_subset,
|
||||
filter_is_common, filter_is_member, filter_next): New filter
|
||||
operations.
|
||||
(dump_filter): Ditto.
|
||||
|
||||
* gen.h, gen.c: New file. Takes the insn table and turns it into
|
||||
a set of decode tables and semantic functions.
|
||||
|
||||
* ld-insn.c: Copy generator code from here.
|
||||
* gen.c: To here.
|
||||
|
||||

|
||||
|
||||
* misc.h (NZALLOC): Allocate an N element array of TYPE.
|
||||
|
||||
* table.h, table.c: Simplify table parser so that it only
|
||||
understands colon delimited lines and code blocks.
|
||||
(table_read): Parse '{' ... '}' as a code block.
|
||||
(table_print_code): New function, print out a code block to file.
|
||||
(main): Add suport for standalone testing.
|
||||
|
||||
* ld-insn.h, ld-insn.c:
|
||||
|
||||
|
||||
Mon Sep 1 11:41:12 1997 Andrew Cagney <cagney@b1.cygnus.com>
|
||||
|
||||
* gen-idecode.c (error_leaf_contains_multiple_insn): Make static.
|
||||
(print_jump_definition, print_jump, print_jump_internal_function,
|
||||
print_jump_insn, print_jump_until_stop_body): Delete, moved to
|
||||
sim-engine.c
|
||||
|
||||
* igen.c (print_itrace_format): Delete unused variable chp.
|
||||
(gen-engine.h): Include.
|
||||
|
||||
* table.c (current_file_name, current_line_entry,
|
||||
current_line_entry): Make static.
|
||||
|
||||
Wed Aug 6 12:31:17 1997 Andrew Cagney <cagney@b1.cygnus.com>
|
||||
|
||||
* configure.in: Define AR_FOR_BUILD, AR_FLAGS_FOR_BUILD,
|
||||
RANLIB_FOR_BUILD and CFLAGS_FOR_BUILD.
|
||||
* configure.in: Include simulator common/aclocal.m4.
|
||||
* configure.in: Add --enable-sim-warnings option.
|
||||
* configure: Re-generate.
|
||||
|
||||
* Makefile.in: Use.
|
||||
|
||||
* Makefile.in (tmp-filter): New rule.
|
||||
(igen.o, tmp-table, tmp-ld-decode, tmp-ld-cache, tmp-ld-insn,
|
||||
ld-decode.o, ld-cache.o, ld-insn.o): Fix dependencies.
|
||||
|
||||
