* libguile/stacks.h: Rework so that a stack doesn't copy information out of VM frames, it just holds onto a VM frame, along with the stack id and length. VM frames are now the only representation of frames in Guile. (scm_t_info_frame, SCM_FRAME_N_SLOTS, SCM_FRAME_REF, SCM_FRAME_NUMBER) (SCM_FRAME_FLAGS, SCM_FRAME_SOURCE, SCM_FRAME_PROC, SCM_FRAME_ARGS) (SCM_FRAME_PREV, SCM_FRAME_NEXT) (SCM_FRAMEF_VOID, SCM_FRAMEF_REAL, SCM_FRAMEF_PROC) (SCM_FRAMEF_EVAL_ARGS, SCM_FRAMEF_OVERFLOW) (SCM_FRAME_VOID_P, SCM_FRAME_REAL_P, SCM_FRAME_PROC_P) (SCM_FRAME_EVAL_ARGS_P, SCM_FRAME_OVERFLOW_P): Remove these macros corresponding to the old frame implementation. (scm_frame_p scm_frame_source, scm_frame_procedure) (scm_frame_arguments): These definitions are now in frames.h. (scm_last_stack_frame): Remove declaration of previously-removed constructor. Probably should re-instate it though. (scm_frame_number, scm_frame_previous, scm_frame_next) (scm_frame_real_p, scm_frame_procedure_p, scm_frame_evaluating_args_p) (scm_frame_overflow_p) : Remove these procedures corresponding to the old stack implementation. * libguile/stacks.c: Update for new frames implementation. * libguile/frames.h: * libguile/frames.c: Rename functions operating on VM frames to have a scm_frame prefix, not scm_vm_frame -- because they really are the only frames we have. Rename corresponding Scheme functions too, from vm-frame-foo to frame-foo. * libguile/deprecated.h: Remove scm_stack and scm_info_frame data types. * libguile/vm.c (vm_dispatch_hook): Adapt to scm_c_make_frame name change. * module/system/vm/frame.scm: No need to export functions provided frames.c now, as we load those procedures into the default environment now. Rename functions, and remove a couple of outdated, unused functions. The bottom half of this file is still bitrotten, though. * libguile/backtrace.c: Rework to operate on the new frame representation. Also fix a bug displaying file names for compiled procedures. * libguile/init.c: Load the VM much earlier, just because we can. Also it allows us to have frames.[ch] loaded in time for stacks to be initialized, so that scm_frame_arguments can do the right thing.
