1116 Make the simulator compatible with the MPC750. It would be nicer
1117 to make this a real multi-sim, but that's more work than we have
1118 time for.
1119 * emul_generic.c (emul_add_tree_options): Only require strict
1120 alignment if it was explicitly requested at configuration time.
1121 Don't make it the default for little-endian machines.
1122 * ppc-spr-table (UMMCR0, UMMCR1, UPMC1, UPMC2, USIA, UPMC3, UPMC4,
1123 MMCR0, PMC1, PMC2, SIA, MMCR1, PMC3, PMC4, L2CR, ICTC, THRM1,
1124 THRM2, THRM3): Plop in the MPC750 SPR registers.
1125 (DABR): This is weird. This was HID5, but the PPC spec says this
1126 should be DABR; why did some random processor use it for something
1127 else? The HID5 entry dates back to the original checkin of the
1128 simulator code in 1995, so remove it.
1129 * sim_calls.c (register_names): Delete this; since the user can
1130 now change GDB's list of register names dynamically, we can't
1131 pretend there's a static mapping here.
1132 (sim_fetch_register, sim_store_register): Call GDB's REGISTER_NAME
1133 function to get the register name. That ought to be accurate.
1134 However, we're changing a compile-time dependency (using the
1135 REGISTER_NAMES macro) into a link- and run-time dependency
1136 (calling REGISTER_NAME, which happens to be a function call on the
1137 PPC).

1170
1171 * table.c (table_open): For cygwin hosts, we need to use the
1172 return value from the read routine as the number of bytes to
1173 process. This apparently is due to text-mode vs binary-mode. If
1174 the mounts are done text-mode, then the size returnedby fstat()
1175 may be different than the number of bytes "read" in text mode.

1681
1682 * hw_trace.c (hw_trace_init_data): Delete. The trace options need
1683 to be initialized independant of the rest of the simulation
1684 initalization. Otherwize a trace option explictly set from gdb

1686
1687 * psim.c (psim_options): Clarify reason why the trace ioctl occures.
1688
1689 * FIXME: The trace code is too scattered - hw_trace.c, psim.c,

1730
1731 * gen-icache.c (print_icache_extraction): For a cache entry of
1732 the form <name>_is_<const> where it is a boolean field, generate

1749 * The code that put values in and extracted values from the cache
1750 was too compilicated. The cache table did not allow values to be

1753
1754 * ld-cache.h, ld-cache.c: Add a new cache entry type - SCRATCH. A

1792 * The cap object was retaining a reference to the instance of a
1793 device after it was deleted. Instead add and remove cap's from the
1794 cap db as they are created and deleted. This ensuring that a
1795 capibility is only used during the lifetime of the corresponding
1796 object.
72f4393d 1797

3091
3092 * gen-idecode.c (print_idecode_switch_illegal): Include a break

c906108c
SS		 3137
3138 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
3139 hardware instead of checking it using ls. configure.in should

72f4393d 3184 instead of just the code to handle a single instruction issue.
c906108c
SS		 3185 * : Have the generated idecode.c include inline.c (instead of psim.c).
3186
3187 * std-config.h: Change psim.c so that it isn't inlined (as this is
72f4393d 3188 no longer needed).

SS		 3189
3190 * psim.c (run_until_stop): Delete the old run_until_stop function
72f4393d
L		 3191 instead calling the idecode_run and idecode_run_until_stop
3192 functions that gen-idecode.c is now creating.

SS		 3220
3221 * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
72f4393d
L		 3222 of ITRACE. The CPP line directives would have previously set the

3225Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
3226
3227 * gen-idecode.c (print_jump_until_stop_body): New function and
72f4393d
L		 3228 idecode generation option. Instead of generating and calling

72f4393d
