Raw Blame History

Thu Oct 12 11:35:53 1995 Michael Meissner <meissner@tiktok.cygnus.com>
* 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.
* inline.h (STATIC_DEVICES): If DEVICES_INLINE is defined to be
non-zero, define STATIC_DEVICES to be static.
* std-config.h (INLINE): If GNU C and optimizing, define this as
__inline__.
(DEFAULT_INLINE): If not defined, define as 0.
(ENDIAN_INLINE): If not defined, define as DEFAULT_INLINE.
({CORE,VM,CPU,EVENTS,REGISTERS,INTERRUPTS}_INLINE): Ditto.
({SPREG,IDECODE}_INLINE): Ditto.
Wed Oct 11 17:13:15 1995 Andrew Cagney <cagney@kremvax>
* 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.
Wed Oct 11 12:10:26 1995 Andrew Cagney <cagney@kremvax>
* sim_calls.c, main.c: Add -g (trace_gdb) option, add tracing to
most of the other functions in sim_calls.c.
* basics.h (CONCAT3), memory_map.c, memory_map_n.h, Makefile.in:
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@kremvax>
* 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@kremvax>
* ppc-instructions (fmul, fmuls): correct instruction format - had
FRB instead of FRC.
Wed Oct 4 17:31:12 1995 Andrew Cagney <cagney@kremvax>
* 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 - aka Noid <cagney@kremvax>
* main.c (printf_filtered, error): Missing va_end() to close off
variable argument use.
* Makefile.in (tmp-gencode): comment out hack to get around some
versions of make not handling files being created as side-effects.
* gen.c (lf_open): Add -n (real_file_name) option. Specifies an
alternative file name to use in output files for things like #line
macros.
Makefile.in (tmp-gencode): Use gen -n so that debug info is
correct.
* Makefile.in (TARGETLIB): Use this instead of libsim.a in the
Makefile.
Sat Oct 7 22:40:59 1995 Michael Meissner <meissner@tiktok.cygnus.com>
* sim_calls.c (sim_set_callbacks): Define new function.
Fri Oct 6 17:23:10 1995 Michael Meissner <meissner@tiktok.cygnus.com>
* psim.c (psim_print_info): Print exit status or signal number.
Mon Oct 2 11:46:37 1995 Michael Meissner <meissner@tiktok.cygnus.com>
* cpu.c (struct _cpu): Add number_of_insns field to trace how many
instructions are executed.
(cpu_increment_number_of_insns): New function to increment the
number of instructions issued.
(cpu_get_number_of_insns): New function to return the number of
instructions issued.
(cpu_print_info): New function to print cpu related information.
At present, print the number of instructions executed.
* gen_idecode_c: Emit call to cpu_increment_number_of_insns within
idecode_issue.
* psim.c (psim_print_info): New function to iterate over each of
the CPU's calling cpu_print_info.
* psim.h,cpu.h: Add new declarations.
* sim_calls.c (sim_open): Add argument processing to add the same
switches main.c accepts for the standalone processor.
(sim_close): Call psim_print_info if -I.
* main.c (main): Add comment saying to update sim_calls.c when
adding switches. Add -I to call psim_print_info when done.
(usage): Update usage message.
Sun Oct 1 13:52:59 1995 Michael Meissner <meissner@tiktok.cygnus.com>
* main.c (printf_filtered): Correct to match new prototype.
Sat Sep 30 20:47:05 1995 Michael Meissner <meissner@tiktok.cygnus.com>
* sim_callbacks.h (printf_filtered): Correct prototype.
Thu Sep 21 16:26:49 1995 Michael Meissner <meissner@tiktok.cygnus.com>
* device_tree.c (OEA_MEMORY_SIZE): Define if not defined to
0x100000.
(clayton_memory_size): Define as OEA_MEMORY_SIZE.
* std-config.h (WITH_TRACE): Default to 1 now.
* psim.c (write_stack_arguments): Don't write any stack arguments
if OEA.
* main.c (main): Switch to using getopt. Make -p also set
trace_semantics. Make -a turn on all trace flags. Make -C turn
on console tracing.
* device_tree.c (create_option_device_node): Assume a program is
OEA if the start address is < 4096, not just == 0.
Wed Sep 20 13:36:06 1995 Ian Lance Taylor <ian@cygnus.com>
* Makefile.in (maintainer-clean): New synonym for realclean.
Sun Sep 10 10:23:56 1995 Michael Tiemann <tiemann@axon.cygnus.com>
* registers.c (register_description): Add gdb synonyms for cr
(cnd) and msr (ps).
Fri Sep 8 13:16:10 1995 Ian Lance Taylor <ian@cygnus.com>
* Makefile.in (install): Don't install in $(tooldir).
* configure.in: Call AC_CONFIG_HEADER. Don't try to use
bfd/hosts/*.h file or bfd/config/*.mh file. Call AC_PROG_CC and
AC_PROG_RANLIB. Substitute in values for CFLAGS, HDEFINES, AR,
and CC_FOR_BUILD. Call AC_CHECK_HEADERS for various header files.
Touch stamp.h if creating config.h.

(mostlyclean): Make the same as clean, not distclean.
(clean): Remove config.log.
(distclean): Remove config.h and stamp-h.
(Makefile): Don't depend upon @frags@. Just rebuild Makefile when
invoking config.status.

longer provides it.
* basics.h (sysdep.h): Don't include it.
* Makefile.in (BASICS_H): Remove sysdep.h.
Wed Sep 6 13:25:42 1995 Andrew Cagney - aka Noid <cagney@kremvax>
* core.c (core_add_data): First growth of bss was being put at
wrong address (0) instead of &end.
* core.c (core_add_stack, core_add_data): Was not handling case
where bss/stack is grown across the current end-of-{bss,stack}.
Wed Sep 6 00:46:10 1995 Andrew Cagney - aka Noid <cagney@kremvax>
* system.c (system_call): Fix SYS_break - was aligning bss to a
page boundary instead of just an 8 byte one; On first call sbrk(0)
!= sbrk(0).
Thu Aug 24 14:48:54 1995 Michael Meissner <meissner@tiktok.cygnus.com>
* Makefile.in (install): Fix install rule.
Tue Aug 22 09:31:18 1995 Michael Meissner <meissner@tiktok.cygnus.com>

* main.c (main): -t sets trace_device_tree. Correct usage message
to current reality.
* device_tree.c (update_memory_node_for_section): Make tracing
output line up. If not code or readonly, assume that the section
is a data section and has read/write permissions. Add readonly
support.
* core.c (create_core_from_addresses): Print end address in traces
and make tracing output line up.
* Makefile.in: Rewrite from Makefile to work with the Cygnus
environment, and support compiling in a different directory than
the sources reside in.
* ppc-endian.h: Rename from endian.h so that it doesn't get
confused with /usr/include/sys/endian.h on Linux. Add Linux
endian support.
* ppc-endian.c: Rename to be consistant with ppc-endian.h.
Include ppc-endian.h, not endian.h.
* basics.h (sysdep.h): Include sysdep.h that configure makes.
Include ppc-endian.h, not endian.h.
* std-config.h: Rename from ppc-config. Put #ifndefs around most
configuration macros, so they can be overridden via CFLAGS. By
default, turn off tracing.
* configure.in: Clone from other simulator targets.
* configure: Generate via autoconf from configure.in.
Sat Aug 19 09:05:32 1995 Andrew Cagney - aka Noid <cagney@kremvax>
* ppc-instructions: fix srawi (was geting XER[CA] real wrong).
* interrupts.c (data_storage_interrupt): allow stack to grow by
upto one MB per increment.
* ppc-instructions: divw was computing rA / rA not rA / rB
* main.c (main): really stupid. Wasn't exiting with correct status
Fri Aug 18 00:38:01 1995 Andrew Cagney - aka Noid <cagney@kremvax>
* system.c (system_call): add system calls kill(2) and getpid(2).
* main.c (main): Check/return exit status when simulation
finishes.
Thu Aug 17 14:29:18 1995 Andrew Cagney <cagney@kremvax>
* 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).
* system.c (system_call) SYS_exit: Wasn't exiting with correct status.
Thu Aug 17 01:16:38 1995 Andrew Cagney - aka Noid <cagney@kremvax>
* vm.c (DEFINE_VM_DATA_MAP_WRITE_N): For miss aligned transfer
forgot to return.
* system.c (system_call): didn't page align break argument before
determining increment break increment.
* 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.
* devices.c, device_tree.c: Added code that provides a simple
illustration of how an interrupt control device could be
implemented.
* devices.c: Added code so that the dumb console device can read
(from stdin) as well as write to stdout.
