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