  45         * Makefile.in (install): Don't install in $(tooldir).
  46
  47         * configure.in: Call AC_CONFIG_HEADER.  Don't try to use
  48         bfd/hosts/*.h file or bfd/config/*.mh file.  Call AC_PROG_CC and
  49         AC_PROG_RANLIB.  Substitute in values for CFLAGS, HDEFINES, AR,
  50         and CC_FOR_BUILD.  Call AC_CHECK_HEADERS for various header files.
  51         Touch stamp.h if creating config.h.
  52         * configure: Rebuild.
  53         * config.in: New file, created by autoheader.

  67         (gen, gen.o): Build with CC_FOR_BUILD, not CC.

  71 Fri Sep  8 09:51:03 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
  72
  73         * configure{,.in}: Don't include sysdep.h from bfd, since bfd no
  74         longer provides it.

  76         * Makefile.in (BASICS_H): Remove sysdep.h.
  77
  78 Wed Sep  6 13:25:42 1995  Andrew Cagney - aka Noid  <cagney@kremvax>
  79
  80         * core.c (core_add_data): First growth of bss was being put at
  81         wrong address (0) instead of &end.
  82
  83         * core.c (core_add_stack, core_add_data): Was not handling case
  84         where bss/stack is grown across the current end-of-{bss,stack}.
  85
  86 Wed Sep  6 00:46:10 1995  Andrew Cagney - aka Noid  <cagney@kremvax>
  87
  88         * system.c (system_call): Fix SYS_break - was aligning bss to a
  89         page boundary instead of just an 8 byte one; On first call sbrk(0)
  90         != sbrk(0).
  91
  92 Thu Aug 24 14:48:54 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
  93
  94         * Makefile.in (install): Fix install rule.
  95
  96 Tue Aug 22 09:31:18 1995  Michael Meissner  <meissner@tiktok.cygnus.com>
  97
  98         * system.c (system_call): Add read support.
  99
 100         * main.c (main): -t sets trace_device_tree.  Correct usage message
 101         to current reality.
 102
 103         * device_tree.c (update_memory_node_for_section): Make tracing
 104         output line up.  If not code or readonly, assume that the section
 105         is a data section and has read/write permissions.  Add readonly
 106         support.
 107
 108         * core.c (create_core_from_addresses): Print end address in traces
 109         and make tracing output line up.
 110
 111         * Makefile.in: Rewrite from Makefile to work with the Cygnus
 112         environment, and support compiling in a different directory than
 113         the sources reside in.
 114
 115         * ppc-endian.h: Rename from endian.h so that it doesn't get
 116         confused with /usr/include/sys/endian.h on Linux.  Add Linux
 117         endian support.
 118
 119         * ppc-endian.c: Rename to be consistant with ppc-endian.h.
 120         Include ppc-endian.h, not endian.h.
 121
 122         * basics.h (sysdep.h): Include sysdep.h that configure makes.
 123         Include ppc-endian.h, not endian.h.
 124
 125         * std-config.h: Rename from ppc-config.  Put #ifndefs around most
 126         configuration macros, so they can be overridden via CFLAGS.  By
 127         default, turn off tracing.
 128
 129         * configure.in: Clone from other simulator targets.
 130         * configure: Generate via autoconf from configure.in.
 131
 132 Sat Aug 19 09:05:32 1995  Andrew Cagney - aka Noid  <cagney@kremvax>
 133
 134         * ppc-instructions: fix srawi (was geting XER[CA] real wrong).
 135
 136         * interrupts.c (data_storage_interrupt): allow stack to grow by
 137         upto one MB per increment.
 138
 139         * ppc-instructions: divw was computing rA / rA not rA / rB
 140
 141         * main.c (main): really stupid. Wasn't exiting with correct status
 142
 143 Fri Aug 18 00:38:01 1995  Andrew Cagney - aka Noid  <cagney@kremvax>
 144
 145         * system.c (system_call): add system calls kill(2) and getpid(2).
 146
 147         * main.c (main): Check/return exit status when simulation
 148         finishes.
 149
 150 Thu Aug 17 14:29:18 1995  Andrew Cagney  <cagney@kremvax>
 151
 152         * device_tree.c (create_option_device_node): Alignment rules (at
 153         least for the moment) now are for strict alignment only for LE OEA
 154         mode.  (Because of compiler problems).
 155
 156         * system.c (system_call) SYS_exit: Wasn't exiting with correct status.
 157
 158 Thu Aug 17 01:16:38 1995  Andrew Cagney - aka Noid  <cagney@kremvax>
 159
 160         * vm.c (DEFINE_VM_DATA_MAP_WRITE_N): For miss aligned transfer
 161         forgot to return.
 162
 163         * system.c (system_call): didn't page align break argument before
 164         determining increment break increment.
 165
 166         * psim/ppc: Re-arange entire directory structure so that
 167         everything lives in the one directory.  While a pain for cleaning,
 168         makes building across multiple architectures much simpler.
 169
 170         * devices.c, device_tree.c: Added code that provides a simple
 171         illustration of how an interrupt control device could be
 172         implemented.
 173
 174         * devices.c: Added code so that the dumb console device can read
 175         (from stdin) as well as write to stdout.
