* config.gcc: Remove default for xm_file.  Clean up local
machine type handling.  Remove settings of xm_file to
something that doesn't exist.  In the big switch, set xm_file,
don't append to it (the value before the big switch is always
null).  Don't force build_xm_file or host_xm_file to have a value.
* configure.in: Remove default for xm_file.  Do not special
case $cpu/xm-$cpu.h not existing.

2001-04-04  Diego Novillo  <dnovillo@redhat.com>

* simplify-rtx.c (simplify_binary_operation): Check for overflow
when folding integer division and modulo operations.

2001-04-04  Diego Novillo  <dnovillo@redhat.com>

* gcc.c-torture/compile/20010404-1.c: New test.

git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@41105 138bc75d-0d04-0410-961f-82ee72b054a4

2001-04-04  Andrew MacLeod  <amacleod@redhat.com>

* dwarf2out.c (output_cfi): Add 'for_eh' parameter, use PTR_SIZE
instead of DWARF2_ADDR_SIZE for EH addresses.
(output_call_frame_info): Use PTR_SIZE instead of DWARF2_ADDR_SIZE for

2001-04-04  Hans Boehm  <hans_boehm@hp.com>

* finalize.c:
- Accomodate finalization requests for static objects.
  (Will be required by hash synchronization.  May be needed
  in some configurations now.)

* gc_priv.h:
- Define MIN_WORDS.  All allocation requests are rounded
  up to at least this size.  Removes a subtle assumption that
  Java objects have a 2 word header.

* gcconfig.h:
- Adjust Linux/IA64 configuration for non-ancient kernels.
  (Necessary fix for IA64.)

* linux_threads.c:
- Fix syntax error in currently unused code.  Will be needed
  for Linux/PA-RISC.

* malloc.c:
- Handle MIN_WORDS.

* misc.c:
- Handle MIN_WORDS.
- Change stack cleaning code to typically clear about one tenth
  the memory it used to in the threads configuration.  Occasionally
  still clear more.  (This is really a fix for a long-standing
  and fairly significant performance bug with threads.)

* os_dep.c:
- Fix the code for finding the beginning of the data segment under
  Linux.  I believe this is necessary for some IA64 Linux
  distributions.  It will also helo other platforms, though those
  may additionally require a gcconfig.h adjustment.  (This basically
  works around the absence of a data_start or __data_start
  definition in glibc.)

* test.c:
- Handle rounding due to MIN_WORDS.
