* parse.y (case_args): moved "duplicated when clause" warning from compile phase, so that `ruby -wc` shows them.

2019-04-09Set a write barrier between iseq and mark objectstenderlove
ISeq pins references in the mark array during compile, so it manually marks references in the mark_ary. This was causing write barrier misses, so we need to add a write barrier when pushing on the mark array. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@67489 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2019-04-05add definemethod/definesmethod insn.ko1
* insns.def: add definemethod and definesmethod (singleton method) instructions. Old YARV contains these instructions, but it is moved to methods of FrozenCore class because remove number of instructions can improve performance for some techniques (static stack caching and so on). However, we don't employ these technique and it is hard to optimize/analysis definition sequence. So I decide to introduce them (and remove definition methods). `putiseq` insn is also removed. * vm_method.c (rb_scope_visibility_get): renamed to `vm_scope_visibility_get()` and make it accept `ec`. Same for `vm_scope_module_func_check()`. These fixes are result of refactoring `vm_define_method`. * vm_insnhelper.c (rb_vm_get_cref): renamed to `vm_get_cref` because of consistency with other functions. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@67442 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2019-03-15node.h: introduce nd_brace to determine if a hash literal is a keywordmame
NODE_HASH#nd_brace is a flag that is 1 for `foo({ k: 1 })` and 0 for `foo(k: 1)`. nd_alen had been abused for the flag (and the implementation is completely the same), but an explicit name is better to read. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@67266 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2019-03-14compile.c (setup_args): process arguments forwardmame
For unknown reason, setup_args processed the arguments from the last to the first. This is not only difficult to read, but also inefficient in some cases. For example, the arguments of `foo(*a1, *a2, *a3)` was compiled like `a1.dup << (a2.dup << a3)`. The second dup (`a2.dup`) is not needed. This change refactors the function so that it processes the arguments forward: `foo(*a1, *a2, *a3)` is compiled as `a1.dup << a2 << a3`, and in my opinion, the source code is now much more readable. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@67255 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2019-03-14compile.c: factor out "compile_args" from "compile_array"mame
compile_array function had three usages: array literal, hash literal, and method arguments. I think the third is completely different than the first and second. For example, method arguments and popped are meaningless; keywords_ptr and flag parameter for array/hash literal is also unused. This change refactors them: a function "compile_args" is created for the third, and removes no longer used parameters of "compile_array". git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@67252 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-12-20Freeze hash literals embedded in duphash instructionsnobu
Previously, these hash literals were not frozen, and thus could be modified by ObjectSpace, resulting in undesired behavior. Example: ```ruby require 'objspace' def a(b={0=>1,1=>4,2=>17}) b end p a ObjectSpace.each_object(Hash) do |a| a[3] = 8 if a.class == Hash && a[0] == 1 && a[1] == 4 && a[2] == 17 end p a ``` It may be desirable to hide such hashes from ObjectSpace, since they are internal, but I'm not sure how to do that.
