2019-03-25use cfp->bp more.ko1
cfp->bp was (re-)introduced by Kokubun san, but VM doesn't use it because I (ko1) want to remove it in a future. But using it make leave instruction fast because of sp consisntency check. So now VM uses cfp->bp. To use cfp->bp, I checked the value and I found that it is not a "initial value of sp" but a "initial value of ep". Fix this problem and fix all bp references (this is why bp is renamed to bp_). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@67342 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-08-11mjit_worker.c: carve out worker-related codek0kubun
The motivation of this change is to make sure rb_funcall or GC-related functions are not called on worker-related code. Currently such functions are used in some places and I believe it's partly because it's hard to identify which part is called on MJIT worker thread. Now, mjit.c is safe to use them but we know we need to safely deal with mjit_compile.c, mjit_worker.c and mjit_internal.h. mjit_compile.c: update the comment about it git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64285 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

which was missing in r64033. Prior to r64033, memory allocation failure had been checked by TRY_WITH_GC and handled by rb_memerror. But calling rb_memerror on MJIT worker is problematic since it does EC_JUMP_TAG in the end. Threads except Ruby's main thread must not use it. mjit_compile.c: ditto git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@64037 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

r63655 was tightly coupled to handle_frames and some assumptions seems to have been broken by r63763. To partially resolve Bug#14892, this reverts the optimization for now.

So I keep it optionally available. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@62741 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-03-04mjit_compile.c: use local variables for stackk0kubun
if catch_except_p is FALSE. If catch_except_p is TRUE, stack values should be on VM's stack when exception is thrown and the JIT-ed frame is re-executed by VM's exception handler. If it's FALSE, the JIT-ed frame won't be re-executed and don't need to keep values on VM's stack. Using local variables allows us to reduce cfp->sp motion. Moving cfp->sp is needed only for insns whose handles_frame? is false. So it improves performance. _mjit_compile_insn.erb: Prepare `stack_size` variable for GET_SP, STACK_ADDR_FROM_TOP, TOPN macros. Share pc and sp motion partial view. Use cancel handler created in mjit_compile.c. _mjit_compile_send.erb: ditto. Also, when iseq->body->catch_except_p is TRUE, this stops to call mjit_exec directly. I described the reason in vm_insnhelper.h's comment for EXEC_EC_CFP. _mjit_compile_pc_and_sp.erb: Shared logic for moving sp and pc. As you can see from thsi file, when status->local_stack_p is TRUE and insn.handles_frame? is false, moving sp is skipped. But if insn.handles_frame? is true, values should be rolled back to VM's stack. common.mk: add dependency for the file _mjit_compile_insn_body.erb: Set sp value before canceling JIT on DISPATCH_ORIGINAL_INSN. Replace GET_SP, STACK_ADDR_FROM_TOP, TOPN macros for the case ocal_stack_p is TRUE and insn.handles_frame? is false. In that case, values are not available on VM's stack and those macros should be replaced. mjit_compile.inc.erb: updated comments of macros which are supported by JIT compiler. All references to `cfp->sp` should be replaced and thus INC_SP, SET_SV, PUSH are no longer supported for now, because they are not used now. vm_exec.h: moved EXEC_EC_CFP definition to vm_insnhelper.h because it's tighly coupled to CALL_METHOD. vm_insnhelper.h: Have revised EXEC_EC_CFP definition moved from vm_exec.h. Now it triggers mjit_exec for VM, and has the guard for catch_except_p on JIT-ed code. See comments for details. CALL_METHOD delegates triggering mjit_exec to EXEC_EC_CFP. insns.def: Stopped using EXEC_EC_CFP for the case we don't want to trigger mjit_exec. Those insns (defineclass, opt_call_c_function) are not supported by JIT and it's safe to use RESTORE_REGS(), NEXT_INSN(). expandarray is changed to pass GET_SP() to replace the macro in _mjit_compile_insn_body.erb. vm_insnhelper.c: change to take sp for the above reason.
