* Remove redundant code in the compiler.tenderlove2018-07-091-21/+4
| | | | | | | | | | | During instruction translation (linked list -> iseq generation), we can treat `TS_VALUE` and `TS_ISEQ` the same as they are just embedded in the generated sequences. The only difference between `TS_ISE` and `TS_IC` is that an inline storage entry may contain a markable `VALUE` pointer at some point, so we need to flag the iseq as containing markable objects. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63923 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | Objects loaded during iseq deserialization using arrays need to be added to the compile time mark array so that they stay alive until iseqs finish loading. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63920 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

| | | | | | | | | * compile.c (iseq_peephole_optimize): remove unreachable jump instruction only. if it is labeled and referred from other instructions, it is reachable and must not be removed.

* Fix a bug of peephole optimizationmame2018-07-061-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | ``` if L1 L0: jump L2 L1: ... L2: ``` was wrongly optimized to: ``` unless L2 L0: L1: ... L2: ``` To make it conservative, this optimization is now disabled when there is any label between `if` and `jump` instructions. Fixes [Bug #14897]. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63868 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* range.c: prohibit `(1..nil)`mame2018-06-131-2/+2
| | | | | | | | | | Now endless range can be created by either a literal `(1..)` or explicit range creation `Range.new(1, nil)`. [Bug #14845] This change is intended for "early failure"; for example, `(1..var).to_a` causes out of memory if `var` is inadvertently nil. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63646 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* rb_vm_insn_addr2insn: use st to perform addr2insn mappingnormal2018-06-061-7/+21
| | | | | | | | | | | | | | | | | The current VM_INSTRUCTION_SIZE is 198, so the linear search painful during a major GC phase. I noticed rb_vm_insn_addr2insn2 showing up at the top of some profiles while working on some malloc-related stuff, so I decided to attack it. Most notably, the benchmark/bm_vm3_gc.rb improves by over 40%: https://80x24.org/spew/20180602220554.GA9991@whir/raw [ruby-core:87361] [Feature #14814] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@63594 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
