2018-10-20vm_insnhelper.c: never cache getinstancevariable twicek0kubun
We have several options to ensure there's no race condition between main thread and MJIT thead about IC reference: 1) Give up caching ivar for multiple classes (or multiple versions of the same class) in the same getinstancevariable (This commit's approach) 2) Allocate new inline cache every time Other ideas we could think of couldn't eliminate possibilities of race condition. In 2, it's memory allocation would be slow and it may trigger JIT cancellation frequently. So 1 would be fast for both VM and JIT situations. git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-09-11_mjit_compile_pc_and_sp.erb: skip moving pck0kubun
when catch_except_p is false and insn.always_leaf? is true (never makes arbitrary method call in the insn). On Optcarrot, unfortunately this didn't have measureable performance impact. But still this is a good direction since it becomes much faster when marking all insns as always leaf. bare_instructions.rb: add `#always_leaf?` that indicates the insn can always be considered as leaf. Using dynamic leaf for JIT would be hard since it requires to discard outdated code somehow. git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-09-11transform_mjit_header.rb: add static to Init_*k0kubun
as well, to make CI succeed with VM_CHECK_MODE > 1. vm_insnhelper.c: drop unnecessary MJIT_HEADER ifdef. This is intended to be ignored by having `static inline`. Removing that by macro would be helpful for minimizing compilation time, but the impact is not so big and having many MJIT_HEADER check would be bad for maintainability. git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-09-11add new instruction attribute called leafshyouhei
An instruction is leaf if it has no rb_funcall inside. In order to check this property, we introduce stack canary which is a random number collected at runtime. Stack top is always filled with this number and checked for stack smashing operations, when VM_CHECK_MODE. [GH-1947] git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
