  69         and CC_FOR_BUILD.  Call AC_CHECK_HEADERS for various header files.
  70         Touch stamp.h if creating config.h.

  98
  99         * core.c (core_add_data): First growth of bss was being put at
 100         wrong address (0) instead of &end.

 103         where bss/stack is grown across the current end-of-{bss,stack}.
 104
 105 Wed Sep  6 00:46:10 1995  Andrew Cagney - aka Noid  <cagney@kremvax>
 106
 107         * system.c (system_call): Fix SYS_break - was aligning bss to a
 108         page boundary instead of just an 8 byte one; On first call sbrk(0)

 110

 112
 113         * Makefile.in (install): Fix install rule.
 114

 116
 117         * system.c (system_call): Add read support.
 118
 119         * main.c (main): -t sets trace_device_tree.  Correct usage message
 120         to current reality.
 121
 122         * device_tree.c (update_memory_node_for_section): Make tracing
 123         output line up.  If not code or readonly, assume that the section
 124         is a data section and has read/write permissions.  Add readonly
 125         support.
 126
 127         * core.c (create_core_from_addresses): Print end address in traces
 128         and make tracing output line up.
 129
 130         * Makefile.in: Rewrite from Makefile to work with the Cygnus
 131         environment, and support compiling in a different directory than
 132         the sources reside in.
 133
 134         * ppc-endian.h: Rename from endian.h so that it doesn't get
 135         confused with /usr/include/sys/endian.h on Linux.  Add Linux
 136         endian support.
 137
 138         * ppc-endian.c: Rename to be consistant with ppc-endian.h.
 139         Include ppc-endian.h, not endian.h.
 140
 141         * basics.h (sysdep.h): Include sysdep.h that configure makes.
 142         Include ppc-endian.h, not endian.h.
 143
 144         * std-config.h: Rename from ppc-config.  Put #ifndefs around most
 145         configuration macros, so they can be overridden via CFLAGS.  By
 146         default, turn off tracing.
 147
 148         * configure.in: Clone from other simulator targets.
 149         * configure: Generate via autoconf from configure.in.
 150
 151 Sat Aug 19 09:05:32 1995  Andrew Cagney - aka Noid  <cagney@kremvax>
 152
 153         * ppc-instructions: fix srawi (was geting XER[CA] real wrong).
 154
 155         * interrupts.c (data_storage_interrupt): allow stack to grow by
 156         upto one MB per increment.
 157
 158         * ppc-instructions: divw was computing rA / rA not rA / rB
 159
 160         * main.c (main): really stupid. Wasn't exiting with correct status
 161
 162 Fri Aug 18 00:38:01 1995  Andrew Cagney - aka Noid  <cagney@kremvax>
 163
 164         * system.c (system_call): add system calls kill(2) and getpid(2).
 165
 166         * main.c (main): Check/return exit status when simulation
 167         finishes.
 168
 169 Thu Aug 17 14:29:18 1995  Andrew Cagney  <cagney@kremvax>
 170
 171         * device_tree.c (create_option_device_node): Alignment rules (at
 172         least for the moment) now are for strict alignment only for LE OEA
 173         mode.  (Because of compiler problems).
 174
 175         * system.c (system_call) SYS_exit: Wasn't exiting with correct status.
 176
 177 Thu Aug 17 01:16:38 1995  Andrew Cagney - aka Noid  <cagney@kremvax>
 178
 179         * vm.c (DEFINE_VM_DATA_MAP_WRITE_N): For miss aligned transfer
 180         forgot to return.
 181
 182         * system.c (system_call): didn't page align break argument before
 183         determining increment break increment.
 184
 185         * psim/ppc: Re-arange entire directory structure so that
 186         everything lives in the one directory.  While a pain for cleaning,
 187         makes building across multiple architectures much simpler.
 188
 189         * devices.c, device_tree.c: Added code that provides a simple
 190         illustration of how an interrupt control device could be
 191         implemented.
 192
 193         * devices.c: Added code so that the dumb console device can read
 194         (from stdin) as well as write to stdout.
