define_bypass guard functions take a pair of rtx_insn
2014-08-21 David Malcolm <dmalcolm@redhat.com>
* genautomata.c (output_internal_insn_latency_func): When writing
the function "internal_insn_latency" to insn-automata.c,
strengthen params "insn" and "insn2" from rtx to rtx_insn *, thus
allowing the optional guard function of (define_bypass) clauses to
expect a pair of rtx_insn *, rather than a pair of rtx.
(output_insn_latency_func): When writing the function
"insn_latency", add an "uncast_" prefix to params "insn" and
"insn2", reintroducing "insn" and "insn2" as rtx_insn * locals
using checked casts from the params, thus enabling the above
change to the generated "internal_insn_latency" function.
