For cygwin hosts, we need to use the return value from the read
[thirdparty/binutils-gdb.git] / sim / ppc / ChangeLog
1 Mon Sep 28 09:42:45 1998 Drew Moseley <dmoseley@cygnus.com>
2
3 * table.c (table_open): For cygwin hosts, we need to use the return value
4 from the read routine as the number of bytes to process. This apparently
5 is due to text-mode vs binary-mode. If the mounts are done text-mode,
6 then the size returnedby fstat() may be different than the number of
7 bytes "read" in text mode.

513
514 * hw_trace.c (hw_trace_init_data): Delete. The trace options need

518
519 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
520
521 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,

584 cache was present, remove the restriction.
585

634 allow the explicit addition and removal of internal objects that
635 the cap knows about.

1854
1855 * ppc-cache-rules (cache): Change RS and RB to cache instead of

1888
1889 * std-config.h (SEMANTICS_INLINE): By default, mask out the
1890 inlining of semantic functions from DEFAULT_INLINE. Almost all
1891 configurations call the semantic code via a pointer so there is
1892 little benefit.
1893

1895
1896 Thu Jul 25 20:07:30 1996 Andrew Cagney <cagney@kremvax.highland.com.au>

1913 dump.
1914
1915 * gen-idecode.c (print_run_until_stop_body): Only generate loop

1920
1921 * gen-icache.c (print_icache_function): Have the cache function
1922 always update the cache_entries semantic and address fields.
1923
1924 * gen-idecode.c (print_idecode_switch_illegal): Include a break
1925 when generating illegal instructions. This was commented out
1926 which is a hangover from looking a at switch statements generated
1927 using indirect jumps.
1928
1929 Tue Jul 23 20:57:01 1996 Andrew Cagney <cagney@kremvax.highland.com.au>

1938 support.h so that, like cpu, it is optionally inlined for all
1939 modules that include it.
1940 * inline.h, inline.c: Adjust so that support.[hc] is handled the
1941 same as cpu.[hc].
1942
1943 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
1944 name for a lable and then branch to it.
1945
1946 * ppc-instructions (convert_to_integer, Floating Round to
1947 Single-Precision, Floating Convert from Integer Doubleword): Use
1948 LABEL and GOTO instead of the recently added switch statements.
1949
1950 Wed Jul 24 14:02:42 1996 Andrew Cagney <cagney@sawnoff.highland.com.au>
1951
1952 * gen-idecode.c (print_run_until_stop_body): Too many rparen in

1968 possible for user packages to be specified.
1969
1970 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
1971 hardware instead of checking it using ls. configure.in should
1972 have taken care of any problems.
1973 (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
1974
1975 Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
1976
1977 * psim.c (psim_options): Enter the argument to the memory size
1978 option directly into the device tree. Was using atol() which is

1999
2000 Mon Jul 22 20:00:25 1996 Andrew Cagney <cagney@highland.com.au>
2001
2002 * emul_generic.c (emul_add_tree_options): Was incorrectly setting
2003 the strict-alignment option when hardwired for non-strict
2004 alignment.
2005
2006 Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2007
2008 * gen-semantics.c: Make the my_index variable a macro MY_INDEX.

2014
2015 * gen-idecode.c: Output the complete run_until_stop function
2016 instead of just the code to handle a single instruction issue.
2017 * : Have the generated idecode.c include inline.c (instead of psim.c).
2018
2019 * std-config.h: Change psim.c so that it isn't inlined (as this is
2020 no longer needed).
2021
2022 * psim.c (run_until_stop): Delete the old run_until_stop function
2023 instead calling the idecode_run and idecode_run_until_stop
2024 functions that gen-idecode.c is now creating.

2051 corresponding call to ITRACE so that it still matches.
2052
2053 * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead

2058
2059 * gen-idecode.c (print_jump_until_stop_body): New function and
2060 idecode generation option. Instead of generating and calling

2074 testing jumping idecodes.
2075

2083
2084 * configure.in (--enable-sim-icache): Accept an option list such

2090
2091 * configure.in: New option --enable-sim-line-nr (default enabled).

2107 * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
2108 that they use the same technique as igen (ie a dummy targets
2109 tmp-pk and tmp-hw are created).
2110
2111 Mon Jun 24 22:28:00 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
2112

2223 core object.
2224
