merge revision(s) 43748,45947,45951: [Backport #9739]

2014-06-27T08:03:11+00:00

	* eval_intern.h (SAVE_ROOT_JMPBUF): workaround for the failure of
	  test/ruby/test_exception.rb on Windows.
	  wrap by __try and __exception statements on mswin to raise SIGSEGV
	  when EXCEPTION_STACK_OVERFLOW is occurred, because MSVCRT doesn't
	  handle the exception.
	  however, (1) mingw-gcc doesn't support __try and __exception
	  statements, and (2) we cannot retry SystemStackError after this
	  change yet (maybe crashed) because SEH and longjmp() are too
	  uncongenial.

	* signal.c (check_stack_overflow, CHECK_STACK_OVERFLOW): now defined on
	  Windows, too.

	* thread_win32.c (ruby_stack_overflowed_p): ditto.

	* thread_win32.c (rb_w32_stack_overflow_handler): use Structured
	  Exception Handling by Addvectoredexceptionhandler() for machine
	  stack overflow on mingw.
	  This would be equivalent to the handling using __try and __exept
	  on mswin introduced by r43748.
	  Exception Handling by AddVectoredExceptionHandler() for machine
	  This would be equivalent to the handling using __try and __except

  for darwin (this header is missing in the iOS SDK)
* eval_intern.h: check HAVE_CRT_EXTERNS_H before including crt_externs.h, if
  not defined, include missing/crt_externs.h instead
* hash.c: ditto
* missing/setproctitle.c: ditto

* vm_core.h, eval_intern.h (CHECK_STACK_OVERFLOW): move

2012-12-25T09:57:07+00:00

  CHECK_STACK_OVERFLOW() to vm_core.h and rename to
  CHECK_VM_STACK_OVERFLOW().
  This change is only move and rename.

* vm_insnhelper.c (vm_stackoverflow): add a function to unify
  raising vm stackoverflow exception.

Fix build when gcc is used and the platform's libc lacks alloca().

2012-11-09T03:34:08+00:00

* include/ruby/ruby.h (alloca), eval_intern.h (alloca), gc.c
  (alloca): Make alloca() globally available by moving the
  ultimate ifdef's to ruby/ruby.h.  Gcc hides its builtin alloca()
  when compiling with -ansi, and linking thus fails on platforms
  that lack their own alloca() implementation in libc, which
  include OpenBSD and some ports of NetBSD.  We use alloca()
  everywhere including from within third party C extentions, so
  alloca() must be made globally available. [Bug #7307]

* addr2line.c (alloca): Replace the alloca() part with the
  ultimate ifdef's. [Bug #7307]

* 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).
