Co-Authored-By: Jeffrey A Law <law@cygnus.com>
From-SVN: r28841
* gcse.c (find_avail_set): Follow chains of register-register copies.
Use oprs_not_set_p to guarantee that the returned value can be
substituted.
(cprop_insn): Don't verify the return value of find_avail_set with
oprs_not_set_p.
From-SVN: r28835
* gcse.c (cprop_jump): New function, broken out of cprop_insn.
(cprop_cc0_jump): New function.
