delta/ruby.git/vm_exec.h, branch ruby_2_1

* vm_exec.h (VM_DEBUG_STACKOVERFLOW): added.

2013-12-18T05:33:50+00:00

  disable stack overflow check for every stack pushing as default.
* vm_exec.c (vm_stack_overflow_for_insn): ditto.

* vm_dump.c (rb_vmdebug_debug_print_pre): Bugfix. Get PC directly.

2013-11-29T12:01:18+00:00

	  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.

vm_core.h: extract VM_STACK_OVERFLOWED_P

2013-11-18T02:29:58+00:00

* 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.

vm_exec.h: fix CHECK_VM_STACK_OVERFLOW_FOR_INSN

2013-07-26T13:14:22+00:00

* vm_exec.h (CHECK_VM_STACK_OVERFLOW_FOR_INSN): surround with
  do/while (0), and remove unnecessary casts.

* vm_exec.h, tool/instruction.rb: not an error, but a BUG if stack

2013-07-26T10:28:26+00:00

  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).

* vm_exec.h (END_INSN): llvm-gcc may optimize out reg_cfp and cause

2013-02-27T03:22:50+00:00

  Stack/cfp consistency error when the instruction doesn't use reg_cfp.
  Usually instructions use PUSH() but for example trace doesn't.
  This hack cause speed down but you shouldn't use llvm-gcc, use clang.
  [Bug #7938]

  instead of asm volatile.
