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.
