* libguile/foreign.c (sym_null_pointer_error): New variable.
(null_pointer_error): New function.
(scm_foreign_set_x): Raise an error if attempting to modify
NULL_POINTER.
(scm_foreign_to_bytevector): Use `null_pointer_error ()' instead of
`scm_misc_error ()'.
* test-suite/tests/foreign.test: New file.
* test-suite/Makefile.am (SCM_TESTS): Add tests/foreign.test.
* test-suite/lib.scm (exception:null-pointer-error): New variable.
OK let's try again. While the thanks go to Daniel Llorens del Río for
the tip, the blame continues going to me :)
* test-suite/Makefile.am:
* test-suite/tests/arrays.test: Add a test.
* libguile/array-map.c (raeql): Handle a few 0-dimensional cases. If the
shapes of the arrays don't match, just return #f instead of raising
an error.
* libguile/eq.c (scm_equal_p): Only call scm_array_equal_p if both
arguments are generalized arrays; otherwise they are not equal. Thanks
to Daniel Llorens del Río for the tip.
* test-suite/Makefile.am:
* test-suite/tests/arrays.test: Add a test.
* module/language/elisp/compile-tree-il.scm: Update for changes to
tree-il (lambda-case, mainly).
* module/language/elisp/spec.scm: Update GPL version to 3. Update reader
for new taking a port and environment argument.
* libguile/_scm.h: Bump objcode version.
* libguile/vm-i-system.c: Fix conflicts.
* module/Makefile.am: Fix conflicts, and add elisp modules to the build.
* test-suite/Makefile.am (SCM_TESTS): Add tests/keywords.test.
* test-suite/standalone/Makefile.am (test-loose-ends): New test.
* test-suite/standalone/test-loose-ends.c: New file.
* test-suite/tests/continuations.test: Three new tests.
* test-suite/tests/keywords.test: New file.
* test-suite/Makefile.am:
* test-suite/tests/brainfuck.test: Add a brainfuck test.
* module/system/base/compile.scm: Also export read-and-compile.
* module/language/tree-il/spec.scm (join): Fix the joiner in the
0-expression case.
* module/language/tree-il/primitives.scm (+): Recognize (+ x -1) as 1-.
* module/language/brainfuck/parse.scm (read-brainfuck): Return EOF if we
actually received EOF, and there were no expressions read.
* module/language/brainfuck/compile-tree-il.scm (compile-body): Fix the
compiler for the new format of "lambda" in tree-il.
* module/language/elisp/lexer.scm: New lexer file.
* test-suite/Makefile.am: Register elisp-reader.test as new test.
* test-suite/tests/elisp-reader.test: New test-case.
* module/language/elisp/README: Document it.
* module/language/elisp/compile-tree-il.scm: Implement defmacro and expansion.
* module/language/elisp/runtime/macro-slot.scm: New module to keep definitions.
* test-suite/Makefile.am: Add elisp-compiler.test to list of tests.
* test-suite/tests/elisp-compiler.test: Basic macro tests.
* module/language/tree-il.scm (parse-tree-il): Fix a number of bugs.
(unparse-tree-il): Apply takes rest args now.
* module/language/tree-il/analyze.scm (analyze-lexicals)
(analyze-lexicals): Heap vars shouldn't increment the number of locals.
* module/language/tree-il/optimize.scm (resolve-primitives!): Don't
resolve public refs to primitives, not at the moment anyway.
* test-suite/Makefile.am (SCM_TESTS): Add tree-il test.
* test-suite/lib.scm (pass-if, expect-fail, pass-if-exception)
(expect-fail-exception): Rewrite as syntax-rules macros. In a very
amusing turn of events, it turns out that bindings introduced by
hygienic macros are not visible inside expansions produced by
defmacros. This seems to be expected, so go ahead and work around the
problem.
* test-suite/tests/srfi-31.test ("rec special form"): Expand in eval.
* test-suite/tests/syntax.test ("begin"): Do some more expanding in eval,
though all is not yet well.
* test-suite/tests/tree-il.test: New test suite, for tree-il->glil
compilation.
* gdbinit: Untested attempts to get the stack fondling macros to deal
with the new program representation.
* libguile/frames.c (scm_vm_frame_arguments, scm_vm_frame_source)
(scm_vm_frame_local_ref, scm_vm_frame_local_set_x): SCM_PROGRAM_DATA is
a struct scm_objcode*.
* libguile/instructions.h:
* libguile/instructions.c: Hide the instruction table and the struct
scm_instruction structure; all access to instructions now goes through
procedures. This is because instructions are no longer in a packed
array indexed by opcode. Also, declare a mask that all instructions
should fit in.
* libguile/objcodes.h:
* libguile/objcodes.c: Rewrite so that object code directly maps its
arity and length from its bytecode. This makes it unnecessary to keep
this information in programs, allowing programs to be simple conses
between the code (objcodes) and data (the object table and the closure
variables).
* libguile/programs.c (scm_make_program): Rework so that make-program
takes objcode, an object table, and externals as arguments. It's much
clearer this way, and we avoid malloc().
* libguile/stacks.c (is_vm_bootstrap_frame): Update for program/objcode
changes.
* libguile/vm-engine.c (vm_run): Initialize the jump table on the first
run, with the opcodes declared in the instruction sources, and with bad
instructions raising an error instead of wandering off into the
Unknown.
* libguile/vm-engine.h (FETCH_LENGTH): Always represent lengths as 3
bytes. The old code was too error-prone.
(NEXT_JUMP): Mask the instruction with SCM_VM_INSTRUCTION_MASK.
(NEW_FRAME): Update for program/objcode changes.
* libguile/vm-expand.h (VM_DEFINE_FUNCTION, VM_DEFINE_INSTRUCTION)
(VM_DEFINE_LOADER): Update so that we explicitly specify opcodes, so
that we have a stable bytecode API.
* libguile/vm-i-loader.c: Update license to LGPLv2+. Explicitly declare
opcodes.
(load-integer): Use an int instead of a long as the accumulator; still
need to revisit this code at some point, I think.
(load-program): Simplify, thankfully!! Just creates the objcode slice
and rolls with it.
* libguile/vm-i-scheme.c: Number the opcodes explicitly.
* libguile/vm-i-system.c: Update license to LGPLv2+. Explicitly declare
opcodes.
(make-closure): Update for new program API.
* libguile/vm.c (vm_make_boot_program): Update for new program/objcode
API. Still a bit ugly.
(scm_load_compiled_with_vm): Update for new program/objcode API.
* module/language/assembly.scm (byte-length): Fix byte-length calculation
for loaders, and load-program.
(code-pack, code-unpack): Start to move things from (system vm conv)
here.
(object->code, code->object): More things from conv.scm.
* module/language/glil.scm (<glil-program>): Add a new field,
closure-level.
(make-glil-program, compute-closure-level): Calculate the "closure
level" when making a glil program. This is the maximum depth of
external binding refs in this closure.
(unparse-glil): Fix label serialization.
* module/language/glil/compile-assembly.scm (make-meta): Prepend #f for
the meta's object table, though maybe in the future we can avoid
creating assembly in the first place.
(assoc-ref-or-acons, object-index-and-alist): GRRR! Caught again by the
different sets of arguments to assoc and assoc-ref!
(glil->assembly): Attempt to make the <glil-program> case more
readable, and fix the bugs. Sorry I don't know how to comment this
change any more than this.
(glil->assembly): For <glil-module> serialize the whole key, not just
the name.
(dump-object): subprogram-code is already a list. Serialize integers as
strings, not u8vectors. Fix the order of lists and vectors.
* module/language/glil/spec.scm (glil): Switch orders, so we prefer glil
-> assembly -> objcode. Actually glil->objcode doesn't work any more,
needs to be removed I think.
* module/language/objcode/spec.scm (objcode->value):
s/objcode->program/make-program/.
* module/language/scheme/inline.scm: Add acons inline.
* module/system/vm/conv.scm (make-byte-decoder): Skip the first 8 bytes,
they are header. Handle subprograms properly. Still needs help though.
(decode-length): Lengths are always 3 bytes now.
* module/system/vm/disasm.scm: Superficial changes to keep things
working. I'd like to fix this better in the future.
* module/system/vm/frame.scm (bootstrap-frame?): Fixes for
program-bytecode.
* module/system/vm/program.scm: Export make-program. It's program-objcode
now, no more program-bytecode.
* module/system/vm/vm.scm (vm-load): Use make-program.
* test-suite/tests/asm-to-bytecode.test: New test, very minimal.
* module/system/vm/objcode.scm: Export word-size, byte-order, and
write-objcode.
