fix typo. * vm_exec.h (DEBUG_END_INSN()): use `ec` instead of `th`. This macro is used when `VMDEBUG > 0`. escape all env properly. * vm_backtrace.c (rb_debug_inspector_open): escape all env using `rb_vm_stack_to_heap()` before making bindings. [Bug #15105] There is a complicated story of this issue: Without this patch, IFUNC frame does not escaped. A IFUNC frame points to CFUNC ep as previous ep. However, CFUNC ep can be escaped because of making bindings of Ruby level frames. IFUNC's ep can points to invalidated ep and `rb_iter_break()` will fail. This is why `any?` fails. * test/-ext-/debug/test_debug.rb: add a test. * remove trailing spaces. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/branches/ruby_2_5@66074 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-12-11vm_exec.h: introduce macros for abstarction.ko1
* vm_exec.h: declare two macros * START_OF_ORIGINAL_INSN() * DISPATCH_ORIGINAL_INSN() instead of inserting label and goto lines. For OPT_CALL_THREADED_CODE, first macro is empty and second macro is simply call the original insn function. * tool/instruction.rb: use above macros. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@61120 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-11-14remove `trace` instruction. [Feature #14104]ko1
* tool/instruction.rb: create `trace_` prefix instructions. * compile.c (ADD_TRACE): do not add `trace` instructions but add TRACE link elements. TRACE elements will be unified with a next instruction as instruction information. * vm_trace.c (update_global_event_hook): modify all ISeqs when hooks are enabled. * iseq.c (rb_iseq_trace_set): added to toggle `trace_` instructions. * vm_insnhelper.c (vm_trace): added. This function is a body of `trace_` prefix instructions. * vm_insnhelper.h (JUMP): save PC to a control frame. * insns.def (trace): removed. * vm_exec.h (INSN_ENTRY_SIG): add debug output (disabled). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60763 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-10-29`th` -> `ec` for VM dump related functions.ko1
* vm_dump.c: `th` -> `ec` (and constify) for: * control_frame_dump * rb_vmdebug_stack_dump_raw * rb_vmdebug_debug_print_register * rb_vmdebug_debug_print_pre * rb_vmdebug_debug_print_post git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60546 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

Fix compile errors for OPT_CALL_THREADED_CODE (in vm_opts.h). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60493 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-10-27`ec` -> `th`ko1
* vm_exec.h (VM_SP_CNT): accepts `ec` instead of `th`. * vm_insnhelper.c (vm_stack_consistency_error): ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60474 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-10-26Use rb_execution_context_t instead of rb_thread_tko1
to represent execution context [Feature #14038] * vm_core.h (rb_thread_t): rb_thread_t::ec is now a pointer. There are many code using `th` to represent execution context (such as cfp, VM stack and so on). To access `ec`, they need to use `th->ec->...` (adding one indirection) so that we need to replace them by passing `ec` instead of `th`. * vm_core.h (GET_EC()): introduced to access current ec. Also remove `ruby_current_thread` global variable. * cont.c (rb_context_t): introduce rb_context_t::thread_ptr instead of rb_context_t::thread_value. * cont.c (ec_set_vm_stack): added to update vm_stack explicitly. * cont.c (ec_switch): added to switch ec explicitly. * cont.c (rb_fiber_close): added to terminate fibers explicitly. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60440 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-08-10rename rb_execution_context_t::stack(_size) to vm_stack(_size).ko1
* vm_core.h: Ruby processes run with two stacks, a machine stack and a VM stack. To make it clear, this fix renames rb_execution_context_t::stack(_size) to vm_stack(_size). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59563 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-06-28move fields to ec.ko1
* vm_core.h (rb_thread.h): move errinfo and trace_arg to rb_execution_context_t. * cont.c (fiber_switch, rb_cont_call): do not restore "trace_arg" here. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59199 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2017-05-09rb_execution_context_t: move stack, stack_size and cfp from rb_thread_tnormal
The goal is to reduce rb_context_t and rb_fiber_t size by removing the need to store the entire rb_thread_t in there. [ruby-core:81045] Work-in-progress: soon, we will move more fields here. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@58614 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-12-18* vm_exec.h (VM_DEBUG_STACKOVERFLOW): added.ko1
disable stack overflow check for every stack pushing as default. * vm_exec.c (vm_stack_overflow_for_insn): ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@44275 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-11-29 * vm_dump.c (rb_vmdebug_debug_print_pre): Bugfix. Get PC directly.tarui
PC is cached into local stack and cfp->pc is incorrent at next of branch or jump. * vm_exec.h (DEBUG_ENTER_INSN): catch up this change. * vm_core.h: update signature of rb_vmdebug_debug_print_pre. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43916 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-11-18vm_core.h: extract VM_STACK_OVERFLOWED_Pnobu
* vm_core.h (VM_STACK_OVERFLOWED_P, WHEN_VM_STACK_OVERFLOWED): extract condition from CHECK_VM_STACK_OVERFLOW. * vm_exec.c (vm_stack_overflow_for_insn): move rb_bug call. * vm_exec.h (CHECK_VM_STACK_OVERFLOW_FOR_INSN): share the condition with CHECK_VM_STACK_OVERFLOW. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43702 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-07-26vm_exec.h: fix CHECK_VM_STACK_OVERFLOW_FOR_INSNnobu
* vm_exec.h (CHECK_VM_STACK_OVERFLOW_FOR_INSN): surround with do/while (0), and remove unnecessary casts. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@42196 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2013-07-26* vm_exec.h, tool/instruction.rb: not an error, but a BUG if stackko1
overflow checking failed just before/after the beginning of an instruction. It should be treated as a BUG. Please tell us if your code cause BUG with this problem. This check will removed soon (for performance). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@42194 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2013-02-27* vm_exec.h (END_INSN): llvm-gcc may optimize out reg_cfp and causenaruse
Stack/cfp consistency error when the instruction doesn't use reg_cfp. Usually instructions use PUSH() but for example trace doesn't.

2012-10-04* vm.c (VM_COLLECT_USAGE_DETAILS): make new VM usage analysisko1
hooks (old macro name is COLLECT_USAGE_ANALYSIS). This feature is only for VM developers. (I'm not sure I can use `VM developers' (the plural form) in this sentence). If VM_COLLECT_USAGE_DETAILS is not 0, VM enables the following usage collection features: (1) insntruction: collect intruction usages. (2) operand: collect operand usages. (3) register: collect register usages. The results are stored in RubyVM::USAGE_ANALYSIS_INSN for (1, 2), RubyVM::USAGE_ANALYSIS_INSN_BIGRAM for (1) and RubyVM::USAGE_ANALYSIS_REGS for (3). You can stop collecting usages with RubyVM::USAGE_ANALYSIS_INSN_STOP(), RubyVM::USAGE_ANALYSIS_OPERAND_STOP(), RubyVM::USAGE_ANALYSIS_REGISTER_STOP() for (1), (2), (3) respectively. You can also change the hook functions by setting C level global variables `ruby_vm_collect_usage_func_(insn|operand|register)' for (1), (2), (3) respectively. See codes for more details. * tool/instruction.rb: fix macro names. * iseq.c (insn_operand_intern): make it export (used in vm.c). fix to skip several processes if not needed (pointer is 0). * vm_dump.c: move codes for collection features to vm.c. * vm_exec.h: rename macro and function names. * vm_insnhelper.h: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@37085 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2012-06-11* vm_core.h: remove lfp (local frame pointer) and renameko1
dfp (dynamic frame pointer) to ep (environment pointer). This change make VM `normal' (similar to other interpreters). Before this commit: Each frame has two env pointers lfp and dfp. lfp points local environment which is method/class/toplevel frame. lfp[0] is block pointer. dfp is block local frame. dfp[0] points previous (parent) environment pointer. lfp == dfp when frame is method/class/toplevel. You can get lfp from dfp by traversing previous environment pointers. After this commit: Each frame has only `ep' to point respective enviornoment. If there is parent environment, then ep[0] points parent envioenment (as dfp). If there are no more environment, then ep[0] points block pointer (as lfp). We call such ep as `LEP' (local EP). We add some macros to get LEP and to detect LEP or not. In short, we replace dfp and lfp with ep and LEP. rb_block_t and rb_binding_t member `lfp' and `dfp' are removed and member `ep' is added. rename rb_thread_t's member `local_lfp' and `local_svar' to `root_lep' and `root_svar'. (VM_EP_PREV_EP(ep)): get previous environment pointer. This macro assume that ep is not LEP. (VM_EP_BLOCK_PTR(ep)): get block pointer. This macro assume that ep is LEP. (VM_EP_LEP_P(ep)): detect ep is LEP or not. (VM_ENVVAL_BLOCK_PTR(ptr)): make block pointer. (VM_ENVVAL_BLOCK_PTR_P(v)): detect v is block pointer. (VM_ENVVAL_PREV_EP_PTR(ptr)): make prev environment pointer. (VM_ENVVAL_PREV_EP_PTR_P(v)): detect v is prev env pointer. * vm.c: apply above changes. (VM_EP_LEP(ep)): get LEP. (VM_CF_LEP(cfp)): get LEP of cfp->ep. (VM_CF_PREV_EP(cfp)): utility function VM_EP_PREV_EP(cfp->ep). (VM_CF_BLOCK_PTR(cfp)): utility function VM_EP_BLOCK_PTR(cfp->ep). * vm.c, vm_eval.c, vm_insnhelper.c, vm_insnhelper.h, insns.def: apply above changes. * cont.c: ditto. * eval.c, eval_intern.h: ditto. * proc.c: ditto. * thread.c: ditto. * vm_dump.c: ditto. * vm_exec.h: fix function name (on vm debug mode). git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@36030 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
