J"orn Rennecke b92ba6ffd9 re PR rtl-optimization/18992 (delete_trivially_dead_insns made ineffective for two-address targets)
PR rtl-optimization/18992
	Back out this patch:
	  2003-10-08  John David Anglin  <dave.anglin@nrc-cnrc.gc.ca>
	  PR optimization/12142
	  * cse.c (count_reg_usage): In a SET with a REG SET_DEST, count the
	  uses of the register in the SET_SRC.  Remove unnecessary argument.

	Replace it with this:
	* cse.c (count_reg_usage): In INSN, JUMP_INSN and CALL_INSN cases,
	if flag_non_call_exceptions is set and the insn may trap, pass
	pc_rtx as dest for recursion.
	In SET_SRC part of SET case, if dest is already set, pass it down
	unchanged.

This directory contains the GNU Compiler Collection (GCC).

The GNU Compiler Collection is free software.  See the file COPYING
for copying permission.  The manuals, and some of the runtime
libraries, are under different terms; see the individual source files
for details.

The directory INSTALL contains copies of the installation information
as HTML and plain text.  The source of this information is
gcc/doc/install.texi.  The installation information includes details
of what is included in the GCC sources and what files GCC installs.

See the file gcc/doc/gcc.texi (together with other files that it
includes) for usage and porting information.  An online readable
version of the manual is in the files gcc/doc/gcc.info*.
