133
134 * std-config.h (SEMANTICS_INLINE): By default, mask out the
135 inlining of semantic functions from DEFAULT_INLINE. Almost all

167 always update the cache_entries semantic and address fields.
168
169 * gen-idecode.c (print_idecode_switch_illegal): Include a break

180 * gen-semantics.c (print_c_semantic): Adjust.
181
182 * gen-support.c (gen_support_h): Add optional include to created
183 support.h so that, like cpu, it is optionally inlined for all
184 modules that include it.
185 * inline.h, inline.c: Adjust so that support.[hc] is handled the
186 same as cpu.[hc].
187
188 * idecode_fields.h (LABEL, GOTO): Macro's that create a unique
189 name for a lable and then branch to it.
190
191 * ppc-instructions (convert_to_integer, Floating Round to
192 Single-Precision, Floating Convert from Integer Doubleword): Use
193 LABEL and GOTO instead of the recently added switch statements.

212 hardware devices that are to be included in the build. Makes it
213 possible for user packages to be specified.
214
215 * Makefile.in (tmp-pk, tmp-hw): Just use the list of packages and
216 hardware instead of checking it using ls. configure.in should
217 have taken care of any problems.
218 (HW_SRC, HW_OBJ, PACKAGE_SRC, PACKAGE_OBJ): Set by configure.
219
220Mon Jul 22 22:38:59 1996 Andrew Cagney <cagney@highland.com.au>
221
222 * psim.c (psim_options): Enter the argument to the memory size
223 option directly into the device tree. Was using atol() which is

30c87b55
MM		 251Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
252

258Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
259
260 * gen-idecode.c: Output the complete run_until_stop function

262 * : Have the generated idecode.c include inline.c (instead of psim.c).
263
264 * std-config.h: Change psim.c so that it isn't inlined (as this is
265 no longer needed).
266
267 * psim.c (run_until_stop): Delete the old run_until_stop function
268 instead calling the idecode_run and idecode_run_until_stop
269 functions that gen-idecode.c is now creating.
270
271Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
272

279
280 * debug.c (TRACE, ITRACE, DTRACE): Have GCC instead of CPP
281 eliminate trace statements.

296 corresponding call to ITRACE so that it still matches.
297
298 * idecode_expression.h (ALU_END, CR0_COMPARE): Use TRACE instead
299 of ITRACE. The CPP line directives would have previously set the
300 line-nr and file name so ITRACE isn't needed.
301
302Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
303
304 * gen-idecode.c (print_jump_until_stop_body): New function and
305 idecode generation option. Instead of generating and calling

308 indirect jump) to move between code blocks.
309
310 * Makefile.in: Add sim_jump flag to those passed to igen.
311
312 * configure.in: New option --enable-sim-jump (default disabled)
313

319 testing jumping idecodes.
320

327 decode functions.
328
329 * configure.in (--enable-sim-icache): Accept an option list such

331 will cause igen to generate instruction decode functions that
332 include the corresponding semantic code.
333
334Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
335
336 * configure.in: New option --enable-sim-line-nr (default enabled).
337 Enable/disable the inclusion of CPP line directives in the
338 generated files. Such directives refer back to the source files
339 used when generating the simulator code.
340
341 * Makefile.in (sim_line_nr): Pass to igen.
342
343Sun Jul 21 21:18:05 1996 Andrew Cagney <cagney@kremvax.highland.com.au>

351
352 * Makefile.in (pk.h, hw.h): Rewrite depenencies for hw.h (etc) so
353 that they use the same technique as igen (ie a dummy targets
354 tmp-pk and tmp-hw are created).
355
356Mon Jun 24 22:28:00 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
357
358 * Makefile.in (BUILD_CFLAGS): Include WARNING_CFLAGS.

391 * Makefile.in (filter.o): Adjust
392 * configure.in: Adjust filter flag so that default includes 32bit
393 and floating point.

1315
1316 * device.c (external_to_device) : New function that provides a
1317 standard mapping between a devices internal representation (a
1318 pointer) and its external (or what is passed to a client)
1319 representation (a phandle). Implement using the cap object
1320 attached to the root node.
1321
1322 * device.c (device_to_external) : Ditto
1323 * device.c (external_to_device_instance) : Ditto but for ihandle
1324 and device instance.

1326
1327 * Makefile (device.o): Add dependency on cap.
1328
1329 * emul_chirp.c (struct _emul_chirp_data) : Elimate use of cap. Code
1330 needing to translate between internal and external representations
1331 changed to use the external_to_device et.al. device operations.
1332 * emul_chirp.c (chirp_emul_*) : Ditto
1333

1342
1343 * emul_generic.c (emul_write_buffer): Use vm faulting byte
1344 read/write calls for buffer transfers. This will cause a fault to
1345 occure if the transfer fails. CHRP catches the fault while the
1346 others suffer the consequences.
