add more byte-code assertions and better failure output
-------------------- ChangeLog entries follow: --------------------
src/ChangeLog addition:
2010-02-03 Ben Wing <ben@xemacs.org>
* alloc.c (Fmake_byte_code):
* bytecode.h:
* lisp.h:
* lread.c:
* lread.c (readevalloop):
* lread.c (Fread):
* lread.c (Fread_from_string):
* lread.c (read_list_conser):
* lread.c (read_list):
* lread.c (vars_of_lread):
* symbols.c:
* symbols.c (Fdefine_function):
Turn on the "compiled-function annotation hack". Implement it
properly by hooking into Fdefalias(). Note in the docstring to
`defalias' that we do this. Remove some old broken code and
change code that implemented the old kludgy way of hooking into
the Lisp reader into bracketed by `#ifdef
COMPILED_FUNCTION_ANNOTATION_HACK_OLD_WAY', which is not enabled.
Also enable byte-code metering when DEBUG_XEMACS -- this is a form
of profiling for computing histograms of which sequences of two
bytecodes are used most often.
* bytecode-ops.h:
* bytecode-ops.h (OPCODE):
New file. Extract out all the opcodes and declare them using
OPCODE(), a bit like frame slots and such. This way the file can
be included multiple times if necessary to iterate multiple times
over the byte opcodes.
* bytecode.c:
* bytecode.c (NUM_REMEMBERED_BYTE_OPS):
* bytecode.c (OPCODE):
* bytecode.c (assert_failed_with_remembered_ops):
* bytecode.c (READ_UINT_2):
* bytecode.c (READ_INT_1):
* bytecode.c (READ_INT_2):
* bytecode.c (PEEK_INT_1):
* bytecode.c (PEEK_INT_2):
* bytecode.c (JUMP_RELATIVE):
* bytecode.c (JUMP_NEXT):
* bytecode.c (PUSH):
* bytecode.c (POP_WITH_MULTIPLE_VALUES):
* bytecode.c (DISCARD):
* bytecode.c (UNUSED):
* bytecode.c (optimize_byte_code):
* bytecode.c (optimize_compiled_function):
* bytecode.c (Fbyte_code):
* bytecode.c (vars_of_bytecode):
* bytecode.c (init_opcode_table_multi_op):
* bytecode.c (reinit_vars_of_bytecode):
* emacs.c (main_1):
* eval.c (funcall_compiled_function):
* symsinit.h:
Any time we change either the instruction pointer or the stack
pointer, assert that we're going to move it to a valid location.
This should catch failures right when they occur rather than
sometime later. This requires that we pass in another couple of
parameters into some functions (only with error-checking enabled,
see below).
Also keep track, using a circular queue, of the last 100 byte
opcodes seen, and when we hit an assert failure during byte-code
execution, output the contents of the queue in a nice readable
fashion. This requires that bytecode-ops.h be included a second
time so that a table mapping opcodes to the name of their operation
can be constructed. This table is constructed in new function
reinit_vars_of_bytecode().
Everything in the last two paras happens only when
ERROR_CHECK_BYTE_CODE.
Add some longish comments describing how the arrays that hold the
stack and instructions, and the pointers used to access them, work.
* gc.c:
Import some code from my `latest-fix' workspace to mark the
staticpro's in order from lowest to highest, rather than highest to
lowest, so it's easier to debug when something goes wrong.
* lisp.h (abort_with_message): Renamed from abort_with_msg().
* symbols.c (defsymbol_massage_name_1):
* symbols.c (defsymbol_nodump):
* symbols.c (defsymbol):
* symbols.c (defkeyword):
* symeval.h (DEFVAR_SYMVAL_FWD_OBJECT):
Make the various calls to staticpro() instead call staticpro_1(),
passing in the name of the C var being staticpro'ed, so that it
shows up in staticpro_names. Otherwise staticpro_names just has
1000+ copies of the word `location'.
