|
|
they are paramaterised with the type of the function. Gets around

comming last. Format declarations and definitions so that emacs
|
|
doesn't get confused.
|
|
|

|
|
|
|
* configure.in (sim_mon, sim_monitor): Correct typo - sim_mon ->
|
|
sim_monitor for shell variable (or should that have been the other
|
|
way around?).
|
|
|
|
* vm.c (vm_synchronize_context): Fix wrong test for unsuported
|
|
change in endian-mode.
|
|
|
|
* std-config.h (WITH_REGPARM), inline.h (IDECODE_INLINE,

|
SEMANTICS_INLINE): Add -DWITH_REGPARM=<n> option. Enables the
|
|
__attribute__((__regparm(WITH_REGPARM))) for some functions.
|
|
configure with --enable-sim-cflags="-DWITH_REGPARAM=3" (say).
|
|
Unfortunatly it tickles a bug (gcc?) and can't be used.

model-data, model-internal. Use annex field for model-macros
|
|
now.
|
|
|
|
* configure.in (--enable-sim-inline): If --enable-sim-inline=no,
|
|
also define INLINE as nothing.
|
|
* configure: Regenerate.
|
|
|
|
* std-config.h (INLINE): Rather than nuking INLINE, only define it
|
|
as __inline__ if any of the INLINE flags are non-zero.
|
|
|

|
* ppc-instructions (rfi): Add missing code.
|
|
|
|

|
|
time base register.
|
|
|
|
* ppc-spr-table (TBL, TBU): Fix TBL/TBU entries - was confusing
|
|
m[tf]tb with m[tf]spr.
|
|
|
|
* ppc-instructions (mtspr, mfspr): Fix mttbl - wasn't storing
|
|
lower word.
|
|
|
|
Mon Nov 13 21:35:37 1995 Andrew Cagney <cagneyhighland.com.au>
|
|
|
|
* std-config.h (INLINE, STATIC_INLINE): Was being set to static
|
|
inline.. Only problem being that with ppc-opcode-simple this gave
|
|
it the chance to inline all the idecode functions with potentially
|
|
disasterous results on a 16mb PC. For moment hobble INLINE.
|
|
|
|
* configure.in, std-config.h (WITH_SMP): Make that 5 processors by
|
|
default ...
|
|
|
|
* configure.in: Tweek flags passed to gcc for --with-sim-warnings.
|
|
Firstly make them errors and secondly remove the options gcc-245
|
|
doesn't reconize.
|
|
|
|
Mon Nov 13 17:57:24 1995 Andrew Cagney <cagney@highland.com.au>
|
|
|
|
* misc.c (zalloc), cpu.c (cpu_init), devices
|
|
(console_io_read_buffer_callback, icu_io_read_buffer_callback,
|
|
vm_io_read_buffer_callback), main.c (zalloc), mon.c (memset),
|
|
sim_calls.c (zalloc) : replace bzero() with memset().
|
|
|
|
* emul_netbsd.c (write_direntries), psim.c (psim_read_register,
|
|
psim_write_register): replace bcopy() with memcpy().
|
|
|
|
Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
|
|
|
|
* configure.in: for --disable-sim-inline (--enable-sim-inline=no),
|
|
force DEFAULT_INLINE to 0 rather then trusting the std
|
|
configuration.
|
|
|
|
Sun Nov 12 20:55:41 1995 Andrew Cagney <cagneyhighland.com.au>
|
|
|
|
* igen.c (lf_print_idecode_table, idecode_table_leaf): Fix
|
|
generation of switch entries in tables - treat the same as
|
|
cracking/semantic functions.
|
|
|
|
* igen.c (idecode_switch_end, idecode_switch_leaf): Fix generation
|
|
of a boolean switch statement (field zero or non-zero).
|
|
|
|
* ppc-opcode-test-1, ppc-opcode-test-2: New files. These test the
|
|
switch/table generation ability of igen.
|
|
|
|
* igen.c (idecode_switch_leaf): Fix code output when a switch
|
|
statement needs to look up a table.
|
|
|
|
* igen.c (idecode_declare_if_switch): New function called from
|
|
gen_idecode_c - need to declare any idecode switch functions
|
|
before they are used in idecode tables.
|
|
|
|
* igen.c (lf_print_c_cracker_function, idecode_crack_leaf,
|
|
idecode_crack_insn): Add is_inline_function argument to code
|
|
printing cracker functions which indicates if STATIC_IDECODE or
|
|
STATIC_INLINE_IDECODE should be used for definition. For
|
|
idecode_crack_insn (which implies not duplicating/expanding) don't
|
|
declare function as inline - we assume that the only time this is
|
|
code is generated is when things are being tested. For
|
|
idecode_crack_leaf, make static (instead of INLINE) if the
|
|
instructions parent is a table as function will always be called
|
|
via a table.
|
|
|
|
* igen.c (idecode_expand_if_switch): Declare as STATIC_IDECODE not
|
|
STATIC_INLINE_IDECODE. Only the outermost idecode switch will be
|
|
called directly, all others are called via a table.
|
|
|
|
* igen.c (lf_print_semantic_function_header, semantics_h_leaf,
|
|
semantics_h_insn, semantics_h_function,
|
|
lf_print_c_semantic_function, semantics_c_function): Add
|
|
is_inline_function argument to lf_print_semantic_function_header
|
|
to indicate if an inline or static function declaration/definition
|
|
should be output. Depending on situtation call accordingly:
|
|
functions (not instruction semantic routines) are always inline;
|
|
Semantic routines are made inline when there is no icache (cache
|
|
will contain the function address) and are duplicating (see above)
|
|
and the parent of the instruction is a switch statement.
|
|
|
|
* igen.c (opcode_field_new): Delete. Code changed to use ZALLOC
|
|
and moved to insn_table_find_opcode_field.
|
|
|
|
* table.c (table_open): Fix typo (nr_model_fields vs nr_fields).
|
|
|
|
* igen.c (model_c_insn): Suggestion - document the name of the
|
|
instruction on each line of the instruction model table.
|
|
|
|

|
|
|
|
Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
|
|
|
|
* std-config.h (WITH_XOR_ENDIAN), configure.in, Makefile.in: New
|
|
macro, indicates if the PowerPC's horrible XOR endian mode should
|
|
be suported. Add to configure and make.
|
|
|
|
* vm_n.h (vm_data_map_read_N, vm_data_map_write_N), vm.c
|
|
(vm_instruction_map_read): If XOR endian, xor the address
|
|
with a value from an xor table (indexed by size of access).
|
|
|
|
* vm.c (vm_synchronize_context), cpu.c (cpu_synchronize_context):
|
|
set up xor table to xor if there is a conflict between the
|
|
CURRENT_TARGET_ENDIAN and the endian indicated in the MSR. Move
|
|
check of suported change of endian mode from cpu.c to vm.c.
|
|
|
|
* vm.c (vm_data_map_write_buffer, vm_data_map_read_buffer):
|
|
Hopefully added correct hack to handle XOR endian mode.
|
|
|
|
FIXME: If NONSTRICT alignment and XOR ENDIAN and MSR indicates
|
|
little endian mode, the model accepts miss aligned transfers.
|
|
|
|
FIXME: Need to create an `init' device that, during
|
|
initializatioin for XOR mode, it mushes (XOR address) all the dma
|
|
data before passing it on to the core for storage. Just like the
|
|
real thing really.
|
|
|
|
Wed Nov 8 21:49:52 1995 Andrew Cagney <cagneyhighland.com.au>
|
|

|
|
|
|
* igen.c (main), misc.h (target_a2i, i2target), misc.c: Add
|
|
functions to convert between target and igen internal bit numbers.
|
|
Make IO go through these functions. Add -b (bit size) and -h (high

|
|
all environment switches for above.

Tue Oct 31 21:31:32 1995 Andrew Cagney <cagney@highland.com.au>
|
|
|
|
* ppc-opcode-stupid: Third example of use of opcode table - this
|
|
one expands all mtspr/mfspr and branch instructions. Appears to
|
|
give about a 10% gain in performance if everything enabled. Also
|
|
takes about 150mb of swap to build.
|
|
|
|
Wed Nov 1 10:49:48 1995 Michael Meissner <meissner@tiktok.cygnus.com>
|
|
|
|
* emul_netbsd.c (do_exit): Print arguments and close parenthesis

integer, use 0, not NULL.
|
|
|
|
Tue Oct 31 15:20:04 1995 Michael Meissner <meissner@tiktok.cygnus.com>
|
|
|
|

|
|
|
|
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.
|
|
|
|
Thu Oct 26 18:31:58 1995 Andrew Cagney <cagney@highland.com.au>
|
|
|
|
* ppc-endian.c (SWAP_8): Fix 8 byte swap!
|
|
|
|
* psim.c (psim_create): Not correctly checking that runtime
|
|
configuration of things like ENDIAN, ENVIRONMENT and ALIGNMENT
|
|
matched the compiled in ones.
|
|
|
|
* debug.h (ITRACE), igen.c: Tidy up more tracing flags -
|
|
trace_semantics is now different to trace_idecode, the former
|
|
checks the cache.
|
|
|
|
Tue Oct 24 21:54:13 1995 Andrew Cagney <cagney@highland.com.au>
|

|
|
simplifies the process of building custom simulators.
|
|
|
|
Mon Oct 23 23:48:59 1995 Andrew Cagney <cagney@highland.com.au>
|
|
|
|
* std-config.h (SEMANTICS_INLINE): Tidy up notes on each of the
|
|
INLINE macros. Make SEMANTICS_INLINE == 1 if DEFAULT_INLINE == 2.
|
|
Don't use DEFAULT_INLINE to define REGISTERS_INLINE DEVICES_INLINE
|
|
DEVICE_TREE_INLINE or INTERRUPTS_INLINE as none of these are on
|
|
the instruction or data critical paths.
|
|
|
|
* FIXME: devices.c/emul_netbsd.c would benefit (slightly) from
|
|
the inclusion of device_tree.c/emul_generic.c.
|
|
|
|
Mon Oct 23 00:31:50 1995 Andrew Cagney <cagney@highland.com.au>
|
|
|
|
* os_emul.[hc], emul_generic.[hc], emul_netbsd.[hc]: replace

|
|
tracing (from spy).
|
|
|
|
Sun Oct 22 21:33:51 1995 Andrew Cagney <cagney@highland.com.au>
|
|
|
|
* cpu.h, cpu.c (cpu_init): New function, zero the registers before
|
|
the processor is started. Fixes problem of registers being
|
|
undefined when restarting from within gdb.
|
|
|
|
* cpu.h, cpu.c (cpu_flush_icache): New function, flushes the
|
|
instruction cache (if present). Fixes problem of cpu caching gdb
|
|
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
|
|
monitoring module. Counts both instructions issued and
|

information is already available from the mon_issue() hook.
|
|
|
|

|
|
|
|
* psim.h, psim.c (psim_create), cpu.h, cpu.c (cpu_create): Attach
|
|
a common monitor to each of the cpus. Delete

replaced by copied code in mon.[hc].
|
|
|
|

|
|
|
|
* sim_calls.c, main.c, psim.c (psim_create): always create
|
|
`WITH_SMP' cpus. The actual number of CPU's active in a
|
|
simulation run is taken from the device node: /init/smp (an
|
|
integer). WITH_SMP changed to 2 (remember to put it back to 0).
|
|
|
|
Fri Oct 20 17:26:54 1995 Andrew Cagney <cagney@highland.com.au>
|
|
|
|
* system.c: More system call emulation. If code appears NetBSD

|
that outputs the instruction tables and dgen that outputs the spr
|
|
tables. Add -f (filter out) flag to igen to filter out certain
|
|
instructions (ex 64 bit ones) from the created tables. Include
|
|
$(LIBIBERTY_LIB) in link options in case host lacks some libc
|
|
functions.
|
|
|
|
* NOTE: igen, since it was originally written for the
|
|
PowerPC/RS6000, things the MSB is 0 and the LSB is 63{31}.
|
|
|
|
* Makefile.in, std-config.h, ppc-cache-rules(new),
|
|
ppc-opcode-complex(new), ppc-opcode-simple(new): (for igen) Create

|
|
an table of all the instructions. Code to output a type

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.
|
|
|
|
* ppc-instructions (64 bit Load Doubleword with Update Indexed):
|
|
Had 32./ instead of 31./
|
|
|
|
* ppc-instructions (64 bit Store Double Word Conditional Indexed):
|
|
bitrot - updated to use newer CR register operators.
|
|
|
|
* ppc-instructions (64bit Floating Convert from Integer
|
|
Doubleword): Correct call to Round_Float().
|
|
|
|
Mon Oct 16 00:31:20 1995 Andrew Cagney <cagney@highland.com.au>
|
|
|
|
* basics.h: #include "sim_callbacks.h" earlier so that its

|
prototypes are declared in all other header files.
|
|
|
|
* bits.h, bits.c, idecode_expression.h (ROTL32, ROTL64): Update
|

Sun Oct 15 20:33:20 1995 Andrew Cagney <cagney@highland.com.au>
|
|
|
|
* debug.h, debug.c (trace_option): New function. Parses the trace
|
|
option, updating the trace array.
|
|
|
|
* debug.h, debug.c (trace_usage): New function. Outputs the list
|
|
of all possible trace options.
|
|
|
|
* sim_calls.c (sim_open), main.c (main): Use new trace_option() to
|
|
parse trace options specified with the simpler -t flag. Adjust
|
|
usage.
|
|
|
|
* FIXME: basic parsing of command line options is still duplicated
|
|
by main.c and sim_calls.c

|
|
|
|
* ppc-endian.c (SWAP_n): Add SET argument to allow use of SWAP
|
|
macros for either assignment or return. Fix SWAP_8 to use a
|
|
union, and two SWAP_4's. Delete SWAP_N, since nobody uses it now.
|
|
(ENDIAN_N): Add SET argument to SWAP_n calls. Delete macro defs
|
|
that hardwired swapping on/off, let optimizer delete dead code.
|
|
|

|
|
the failing address.
|

|
Thu Oct 19 21:43:39 1995 Fred Fish <fnf@fishfood.amigalib.com>
|
|
|
|

Mon Oct 16 17:34:24 1995 Michael Meissner <meissner@tiktok.cygnus.com>
|
|
|
|
* gen.c (lf_print_c_semantic_function): Move counting # of
|
|
instructions here so it works with caching.
|
|
(gen_idecode_c): Move from here.
|
|
|
|
Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
|
|
|
|
* gen.c, ppc-instructions, psim.c: Fix code for generating
|
|
cracking instruction cache. Delete the code that cached just the

|
Fri Oct 13 09:58:43 1995 Michael Meissner <meissner@tiktok.cygnus.com>
|
|
|
|
* Makefile.in (gen.o): Include $(INLINE_CFLAGS).

|
|
* debug.c (ppc_trace): Ditto.
|
|
* sim_calls.c (sim_open): Change trace -> ppc_trace.

|
* cpu.c (cpu_add_commas): Remove extra static.
|
|
|
|
Thu Oct 12 11:35:53 1995 Michael Meissner <meissner@tiktok.cygnus.com>
|
|
|
|
* Makefile.in (psim.o): Now that inlines are turned on, make
|
|
psim.o depend on all sources.
|
|
|
|
* cpu.c (cpu_add_commas): New function to format a long with
|
|
commas.
|
|
(cpu_print_info): Use it to print number_of_insns.
|
|
|
|
* ppc-endian.c (SWAP_n): New macros to speed up byte swapping for
|
|
2, 4, and 8 bytes.
|
|
(ENDIAN_N): If both target and host byte orders are known, don't
|
|
bother testing CURRENT_{TARGET,HOST}_BYTE_ORDER.
|
|
|
|
* ppc-endian.h (target specific H2T_n/T2H_n macros): Remove #if 0
|
|
to allow target specific H2T_n/T2H_n macros to be used.
|
|
(htonl, ntohl): If compiled on a 486 by GCC and WITH_BSWAP is
|
|
non-zero, redefine the htonl/ntohl macros to use the BSWAP instead
|
|
of the 3 instruction sequence that runs on 386s.
|
|
|
|
* std-config.h (WITH_{HOST,TARGET}_BYTE_ORDER): Don't override if
|
|
specified on the compile line.
|
|
(WITH_BSWAP): If not defined, define as 0.
|
|
|
|
* Makefile.in (INLINE_CFLAGS): Add -DDEFAULT_INLINE=2 to add
|
|
default inline support. Pass INLINE_CFLAGS when compiling.
|
|
|
|
* devices.{h,c} (unimp_device_ioctl): Use STATIC_DEVICES, not
|
|
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.
|
|
|
|
* inline.c: Correct pathnames of included C files to match current
|
|
implementation.
|
|
|

|
|
non-zero, define STATIC_DEVICES to be static.
|
|
|

|
Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@highland.com.au>
|
|
|
|
* ppc-instructions: Initial cut of floating point suport added.
|
|
Of note include - use of host IEEE floating point instructions,
|
|
use of PowerPC manual pseudo code to handle the FPSCR. It is not
|
|
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
|
|
with core_map. This removes a level of pointer indirection when
|
|
translating an address.
|
|
|
|
* memory_map.h, memory_map.c, memory_map_n.h: delete.
|
|
|
|
* Makefile.in et.al (sorry): tweek to use new core, core_map and
|
|
core.h.

|
|
Add macros to better cover up `generic' code. Makes it possible
|
|
to step through the generic code!
|
|
|
|
* vm.c, vm_n.h, Makefile.in: ditto
|
|
|
|
Tue Oct 10 15:42:59 1995 Andrew Cagney <cagney@highland.com.au>
|
|
|
|
* devices.h, devices.c, memory_map.h, memory_map.c: Changed
|
|
callback interface so that there is a read/write buffer but no
|
|
read/write_word. VEA default memory read/write handler sometimes
|
|
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:
|
|
eliminate transfer_mode (raw or cooked) parameter from read/write
|
|
buffer.
|
|
|
|
Fri Oct 6 20:23:56 1995 Andrew Cagney <cagney@highland.com.au>

|
|
FRB instead of FRC.
|
|
|
|

|
|
|
|
* psim.c, device_tree.h, device_tree.c, devices.c (printd_*,
|
|
scand_*): new functions to parse/print fields in device names
|
|
while hiding any machine dependency.
|
|
|
|
* devices.c, psim.c: Change the stack init code so that it is
|
|
handled by a device. Arguments passed across using a device ioctl
|
|
(hack).
|
|
|
|
* devices.h, devices.c: device ioctl callback changed to allow a
|
|
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>
|
|
|
|
* main.c (printf_filtered, error): Missing va_end() to close off
|
|
variable argument use.
|
|
|

|
|
alternative file name to use in output files for things like #line
|
|
macros.

|
|
correct.
|
|
|

|
|
determining increment break increment.
|
|
|
|
* psim/ppc: Re-arange entire directory structure so that
|
|
everything lives in the one directory. While a pain for cleaning,
