* vm.c (VM_COLLECT_USAGE_DETAILS): make new VM usage analysis

2012-10-04T12:31:05+00:00

  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.

* vm_core.h: remove lfp (local frame pointer) and rename

2012-06-11T03:14:59+00:00

  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).
