From f3c5239b16b983f1cea6c7710aae052f54e94ff8 Mon Sep 17 00:00:00 2001 From: ko1 Date: Wed, 24 Oct 2018 01:57:27 +0000 Subject: introduce new YARV insn newhashfromarray. * insns.def (newhashfromarray): added to replace `core_hash_from_ary` method to eliminate method call overhead. On my environment, I got the following benchmark results: x = {x: 1} modified: 7864988.6 i/s trunk: 6004098.1 i/s - 1.31x slower x = {x: 1, y: 2} trunk: 6127338.4 i/s modified: 5232380.0 i/s - 1.17x slower x = {x: 1, y: 2, z: 3} modified: 6089553.1 i/s trunk: 5249333.5 i/s - 1.16x slower This trivial improvement should be reconsider because of usage of this instruction. * compile.c: ditto. * defs/id.def, vm.c: remove unused functions. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@65343 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- insns.def | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'insns.def') diff --git a/insns.def b/insns.def index 5d04e5066a..c6b5064794 100644 --- a/insns.def +++ b/insns.def @@ -512,6 +512,18 @@ newhash } } +/* make new Hash object from (frozen) Array object */ +DEFINE_INSN +newhashfromarray +(rb_num_t num, VALUE ary) +() +(VALUE hash) +{ + VM_ASSERT(num * 2 == RARRAY_LEN(ary)); + hash = rb_hash_new_with_size(num); + rb_hash_bulk_insert(num * 2, RARRAY_CONST_PTR(ary), hash); +} + /* put new Range object.(Range.new(low, high, flag)) */ DEFINE_INSN newrange -- cgit v1.2.3
