MM		 9Wed Jan 29 12:32:41 1997 Michael Meissner <meissner@tiktok.cygnus.com>
10
11 * configure.in (sim_callback): If the gdb is post 4.16, configure
12 callback support from the common directory.
13 * configure: Regenerate.
14
15 * Makefile.in (BUILT_SRC_WO_CONFIG): Add targ-vals.{h,def} and
16 targ-map.c.

25
26 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
27 to be initialized independant of the rest of the simulation
28 initalization. Otherwize a trace option explictly set from gdb
29 could be overridden by hw_trace.
30
31 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
32
33 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,
34 debug.c. It could be much simpler.
35
36Thu Jan 23 09:07:26 1997 Andrew Cagney <cagney@kremvax.tpgi.com.au>

73 branches.
74
75 * gen-icache.c (print_icache_extraction): For a cache entry of
76 the form <name>_is_<const> where it is a boolean field, generate

92
93 * The code that put values in and extracted values from the cache
94 was too compilicated. The cache table did not allow values to be
95 computed from cache entries. #defines could only be used when a
96 cache was present, remove the restriction.
97
98 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A
99 scratch variable is defined when a cache entry is beinf

118 cache.
119
120 * configure.in (enable-sim-icache): Clarify description. Make
121 #define one of the defaults regardless of the cache. Probably
122 should revamp and add a separate option.

1400
1401 * std-config.h (SEMANTICS_INLINE): By default, mask out the
1402 inlining of semantic functions from DEFAULT_INLINE. Almost all

1434 always update the cache_entries semantic and address fields.
1435
1436 * gen-idecode.c (print_idecode_switch_illegal): Include a break
1437 when generating illegal instructions. This was commented out
1438 which is a hangover from looking a at switch statements generated
1439 using indirect jumps.
1440
1441Tue Jul 23 20:57:01 1996 Andrew Cagney <cagney@kremvax.highland.com.au>

1450 support.h so that, like cpu, it is optionally inlined for all
1451 modules that include it.
1452 * inline.h, inline.c: Adjust so that support.[hc] is handled the
1453 same as cpu.[hc].
1454
1455 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
1456 name for a lable and then branch to it.
1457
1458 * ppc-instructions (convert_to_integer, Floating Round to
1459 Single-Precision, Floating Convert from Integer Doubleword): Use
1460 LABEL and GOTO instead of the recently added switch statements.
1461
1462Wed Jul 24 14:02:42 1996 Andrew Cagney <cagney@sawnoff.highland.com.au>
1463
1464 * gen-idecode.c (print_run_until_stop_body): Too many rparen in

1482 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
1483 hardware instead of checking it using ls. configure.in should
1484 have taken care of any problems.
1485 (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
1486
1487Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
1488
1489 * psim.c (psim_options): Enter the argument to the memory size
1490 option directly into the device tree. Was using atol() which is

1514 * emul_generic.c (emul_add_tree_options): Was incorrectly setting
1515 the strict-alignment option when hardwired for non-strict
1516 alignment.
1517

MM		 1518Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
1519
1520 * gen-semantics.c: Make the my_index variable a macro MY_INDEX.

1526
1527 * gen-idecode.c: Output the complete run_until_stop function
1528 instead of just the code to handle a single instruction issue.
1529 * : Have the generated idecode.c include inline.c (instead of psim.c).
1530
1531 * std-config.h: Change psim.c so that it isn't inlined (as this is
1532 no longer needed).
1533
1534 * psim.c (run_until_stop): Delete the old run_until_stop function
1535 instead calling the idecode_run and idecode_run_until_stop
1536 functions that gen-idecode.c is now creating.
1537
1538Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
1539
1540 * dgen.c: Maintenance - update to use new features found in lf.c.

1563 corresponding call to ITRACE so that it still matches.
1564
1565 * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
1566 of ITRACE. The CPP line directives would have previously set the
1567 line-nr and file name so ITRACE isn't needed.

1570
1571 * gen-idecode.c (print_jump_until_stop_body): New function and
1572 idecode generation option. Instead of generating and calling

1586 testing jumping idecodes.
1587

1594 decode functions.
1595
1596 * configure.in (--enable-sim-icache): Accept an option list such
1597 as 1024,define. Add a new choice to the list - semantic - which
1598 will cause igen to generate instruction decode functions that
1599 include the corresponding semantic code.
1600
1601Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
1602
1603 * configure.in: New option --enable-sim-line-nr (default enabled).
1604 Enable/disable the inclusion of CPP line directives in the
1605 generated files. Such directives refer back to the source files
1606 used when generating the simulator code.

1618
1619 * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
1620 that they use the same technique as igen (ie a dummy targets
1621 tmp-pk and tmp-hw are created).
1622
1623Mon Jun 24 22:28:00 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
