- printing cracker functions which indicates if STATIC_IDECODE or
- STATIC_INLINE_IDECODE should be used for definition. For

- will contain the function address) and are duplicating (see above)
- and the parent of the instruction is a switch statement.
+ * device.c (device_tree_add_parsed): Check that the creation of a

+Thu Mar 21 00:14:26 1996 Andrew Cagney <cagney@highland.com.au>
- FIXME: Need to create an `init' device that, during

- variables.
- * configure: Regenerate from configure.in.
- * Makefile.in: Add various Make variables that the various
- switches alter.
-
- * std-config.h (DEFAULT_INLINE): Don't set this to 2 if using GCC

-
-Fri Oct 27 19:26:27 1995 Andrew Cagney <cagney@highland.com.au>
-
- * bits.h (ROTL32, ROTL64): Were functions, made them macros, now
- make them functions again. Appears 2.6.3 is confused by just a
- macro.

-
- * ppc-endian.c (SWAP_8): Fix 8 byte swap!

-
- * ppc-instructions (mtsrin): Missing instruction

- the instruction or data critical paths.
-
- * FIXME: devices.c/emul_netbsd.c would benefit (slightly) from

-
-Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au>

- breakpoint instructions.
-
- FIXME: PSIM sometimes aborts calling error(), it should instead
- call sim_error() say which takes care of housekeeping such as
- saving the CIA before calling error.
-
- * NOTE: cpu_flush_cache() instead of cpu_synchronize_context() is
- used when restarting a simulation because the latter has the
- unwanted side effect (well I as a kernel hacker think it is) of
- performing an isync when the instruction stream doesn't contain
- one.
-
-Sun Oct 22 19:27:48 1995 Andrew Cagney <cagney@highland.com.au>
-
- * mon.h (new), mon.c (new), std-config.h (WITH_MON): Performance

-
-Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
-
- * system.c: More system call emulation. If code appears NetBSD
- specific, make conditional to being compiled on a NetBSD system
- (sigh).
-

- functions.
-
- * NOTE: igen, since it was originally written for the

- enumerating all the instructin names.
-
- * igen.c(lf_print_c_semantic): Move call to increment instruction
- counter so that it occures _after_ the instruction has been fully
- validated, was double counting illegal/invalid instructions. Add
- conditional so only compiled in when WITH_PROFILE enabled (enabled
- by default).
-
- * igen.c, cpu.h, cpu.c(cpu_increment_number_of_insns): Include
- itable.h, count individual instruction types not just total,
- adjust reporting functions to output this.

- INLINE_DEVICES since GCC doesn't like inline functions that
- accept variable arguments.
- (stack_ioctl_callback): Make function just static because GCC
- doesn't like inline functions that accept variable arguments.
-
- * devices.h (STATIC_DEVICES): Define as empty if not defined.

- currently a pretty sight.
-
- * memory_map.h, memory_map.c, memory_map_n.h, core.h, core.c:
- merge into core.h, core.c, core_n.h. The type memory_map replaced

- couldn't resolve an access and of those some were for a memory
- fault and some were because gdb was making a bogus request.
-
- * devices.h, devices.c, memory_map.h, memory_map.c, vm.h, vm.c:

- variable number of arguments. This gives greater flexability and
- greater chance of bugs.
-
-Tue Oct 3 22:01:56 1995 Andrew Cagney <cagney@highland.com.au>

+ (split_value): New function, parses the value part of a device
+ spec.
- * configure.in: Clone from other simulator targets.
- * configure: Generate via autoconf from configure.in.
+ * device.c (device_tree_add_parsed): Use the interrupt conversion
+ functions to determine the interrupt port numbers.
-Sat Aug 19 09:05:32 1995 Andrew Cagney <cagney@highland.com.au>
+ * device_table.h: Add table that maps between an interrupts
+ symbolic name and its port number.
- * ppc-instructions: fix srawi (was geting XER[CA] real wrong).
+ * device.h, device.c (device_interrupt_decode,
+ device_interrupt_encode): new functions use the recently added
+ interrupt port name/number tables to perform conversion.
- * interrupts.c (data_storage_interrupt): allow stack to grow by
- upto one MB per increment.
+Sun Mar 3 03:23:59 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
- * ppc-instructions: divw was computing rA / rA not rA / rB
+ * device.h, device.c (device_set_array_property,
+ device_set_boolean_property, device_set_ihandle_property,
+ device_set_integer_property, device_set_string_property): New
+ functions - allow the value of a given property to be changed.
- * main.c (main): really stupid. Wasn't exiting with correct status
+ * device.h, device.c: Re-order declaration and definition of
+ property functions.

+Sun Mar 3 03:10:22 1996 Andrew Cagney <cagney@kremvax.highland.com.au>
- * system.c (system_call): add system calls kill(2) and getpid(2).
+ * device.c (device_tree_print_device, device_tree_add_parsed):
+ Remove references to phandle properties.
- * main.c (main): Check/return exit status when simulation
- finishes.

+ * device_table.h: Revamp device init callbacks so that they are a
+ sub structure.
+ * device.c (device_init_data, device_init_address): If an init
+ callback is NULL assume it should do nothing.
+ * device_table.c (ignore_device_init, unimp_device_init): delete
+ as redundant.
+ * device_table.c, hw_memory.c: adjust.
- * device_tree.c (create_option_device_node): Alignment rules (at
- least for the moment) now are for strict alignment only for LE OEA
- mode. (Because of compiler problems).
+ * (io): ditto.
+ * (dma): ditto.
+ * (device_instance): ditto.
+ * (ioctl): ditto.
+ * (address nee config_address): ditto.
+ * (interrupt): ditto.
- * system.c (system_call) SYS_exit: Wasn't exiting with correct status.

-Thu Aug 17 01:16:38 1995 Andrew Cagney <cagney@highland.com.au>
+ * Makefile.in (hw.h, hw.c): New targets. Create from the list of
+ hw_*.c files. hw.h declares a device descriptor table for each hw
+ device while hw.c lists those tables in a form suitable for the
+ construction of a top leveltable in device_table.c.
- * vm.c (DEFINE_VM_DATA_MAP_WRITE_N): For miss aligned transfer
- forgot to return.
+ * Makefile.in (device_table.o): now depends on hw.c a generated
+ table of hw.
- * system.c (system_call): didn't page align break argument before
- determining increment break increment.
+ * device_table.c (device_table): Re-arange the table of devices so
+ that two levels are possible. Make use of hw.c.
+ * device_table.h: ditto.
- * psim/ppc: Re-arange entire directory structure so that
- everything lives in the one directory. While a pain for cleaning,
- makes building across multiple architectures much simpler.
+ * device.c (device_template_create_device): Handle new two level
+ device lookup table.
+ * device.c (device_usage): ditto.
- * devices.c, device_tree.c: Added code that provides a simple
- illustration of how an interrupt control device could be
- implemented.
+Mon Feb 26 22:24:00 1996 Andrew Cagney - aka Noid <cagney@highland.com.au>
- * devices.c: Added code so that the dumb console device can read
- (from stdin) as well as write to stdout.
+ * device_table.c: Delete the memory device (moved to hw_memory.c).
+ * hw_memory.c: New file. Just an OpenBoot memory device.
