This is a bug report for perl from jim.cromie@gmail.com,
generated with the help of perlbug 1.39 running under perl 5.15.2.
-----------------------------------------------------------------
[Please describe your issue here]
pair of patches generate 2 more OP_IS_* macros:
regen/opcode.pl: generate OP_IS_DIRHOP, use in gv.c
Generate OP_IS_DIRHOP like other OP_IS_* macros,
use in gv.c:Perl_gv_add_by_type().
Modifies D operand type to DF.
This yields a micro-optimization.
implement OP_IS_NUMCOMPARE like other OP_IS macros
other macros are written by regen/opcode.pl into opnames.h
Generate OP_IS_NUMCOMPARE the same way, and get a micro-optimization.
Adds a new 'S<' operand type for the numeric comparison ops.
Needs make regen.
[Please do not change anything below this line]
