mjit.c: copy inline cache values to MJIT worker
on VM_CHECK_INTS. Letting MJIT worker directly see inline cache which may be being updated could result in inconsistent IC index and serial. mjit_worker.c: request the copy job after dequeue, and receive the result synchronously. tool/ruby_vm/views/_mjit_compile_ivar.erb: use the copied IC mjit_compile.c: change the interface to pass is_entries mjit.h: ditto === Optcarrot Benchmark === Thankfully this didn't have major performance regression. $ benchmark-driver benchmark.yml --rbenv 'before::before --disable-gems --jit;after::after --disable-gems --jit' -v --repeat-count 24 before: ruby 2.6.0dev (2018-10-21 trunk 65263) +JIT [x86_64-linux] after: ruby 2.6.0dev (2018-10-21 trunk 65263) +JIT [x86_64-linux] last_commit=mjit.c: copy inline cache values to MJIT worker Calculating ------------------------------------- before after Optcarrot Lan_Master.nes 85.421 85.454 fps Comparison: Optcarrot Lan_Master.nes after: 85.5 fps before: 85.4 fps - 1.00x slower git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
