* core.c (core_add_data): First growth of bss was being put at
|
|
wrong address (0) instead of &end.
|
|
|
|

|
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): 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.

|
|
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.

|
|
|
|
* 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).

|
|
finishes.

|

|
|
|
|
* 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.
