The effectiveness of delete_trivially_dead_insns has been considerably
reduced last year.
I have sent a patch here:
http://gcc.gnu.org/ml/gcc-patches/2004-05/msg01037.html
which is still waiting for review.

* 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.
