gcc/ChangeLog:
2014-09-09 David Malcolm <dmalcolm@redhat.com>
* combine.c (try_combine): Eliminate checked cast on result of
gen_rtx_INSN.
* emit-rtl.c (gen_rtx_INSN): New function, improving over the prior
autogenerated one by strengthening the return type and params 2 and 3
from rtx to rtx_insn *, and by naming the params.
* gengenrtl.c (special_rtx): Add INSN to those that are
special-cased.
* rtl.h (gen_rtx_INSN): New prototype.
