Fri Sep 8 09:51:03 1995 Michael Meissner <meissner@tiktok.cygnus.com>
* configure{,.in}: Don't include sysdep.h from bfd, since bfd no
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>
* system.c (system_call): Add read support.
* 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.
