* module/language/elisp/README: Document it.
* module/language/elisp/compile-tree-il.scm: Implement guile-primitive.
* test-suite/tests/elisp-compiler.test: Switched a usage of guile-ref to
the now available guile-primitive.
* module/language/elisp/README: Document it.
* module/language/elisp/bindings.scm: New fields in bindings data structure
to keep track of lexical bindings for symbols.
* module/language/elisp/compile-tree-il.scm: Implement lexical-let(*).
* test-suite/tests/elisp-compiler.test: Test lexical scoping with lexical-let.
* libguile/objcodes.c (OBJCODE_COOKIE): Bump objcode cookie, as we added
to struct scm_objcode.
* libguile/objcodes.h (struct scm_objcode): Add a uint32 after metalen
and before base, so that if the structure has 8-byte alignment, base
will have 8-byte alignment too. (Before, base was 12 bytes from the
start of the structure, now it's 16 bytes.)
* libguile/vm-engine.h (ASSERT_ALIGNED_PROCEDURE): Add a check that can
be turned on with VM_ENABLE_PARANOID_ASSERTIONS.
(CACHE_PROGRAM): Call ASSERT_ALIGNED_PROCEDURE.
* libguile/vm-i-system.c (long-local-ref): Add a missing semicolon.
* libguile/vm.c (really_make_boot_program): Rework to operate directly
on a malloc'd buffer, so that the program will be 8-byte aligned.
* module/language/assembly.scm (*program-header-len*): Add another 4 for
the padding.
(object->assembly): Fix case in which we would return (make-int8 0)
instead of (make-int8:0). This would throw off compile-assembly.scm's
use of addr+.
* module/language/assembly/compile-bytecode.scm (write-bytecode): Write
out the padding int.
* module/language/assembly/decompile-bytecode.scm (decode-load-program):
And pop off the padding int too.
* module/language/glil/compile-assembly.scm (glil->assembly): Don't pack
the assembly, assume that assembly.scm has done it for us. If a
program has a meta, pad out the program so that meta will be aligned.
* test-suite/tests/asm-to-bytecode.test: Adapt to expect programs to
have the extra 4-byte padding int.
* module/language/elisp/README: Document the change.
* module/language/elisp/compile-tree-il.scm: Add disable-void-check option.
* test-suite/tests/elisp-compiler.test: Test it.
* libguile/objcodes.h (struct scm_objcode): Remove the "unused" field --
the old "nexts" -- and expand nlocs to 16 bits.
* module/language/assembly/compile-bytecode.scm (write-bytecode): Write
the nlocs as a uint16.
* module/language/assembly/decompile-bytecode.scm (decode-load-program):
Decompile 16-bit nlocs. It seems this decompilation is little-endian
:-/
* test-suite/tests/asm-to-bytecode.test: Fix up to understand nlocs as a
little-endian value. The test does the right thing regarding
endianness.
* module/language/elisp/README: Document it.
* module/language/elisp/compile-tree-il.scm: Implement flet and flet*.
* test-suite/tests/elisp-compiler.test: Test flet and flet*.
* libguile/programs.h:
* libguile/programs.c: (SCM_PROGRAM_FREE_VARIABLES): Rename from
SCM_PROGRAM_FREE_VARS. Callers changed.
* libguile/programs.c (scm_make_program): Rename arg to
"free_variables".
(scm_program_free_variables): Rename from program-free-vars.
* libguile/vm-engine.h:
* libguile/vm-engine.c (VM_CHECK_FREE_VARIABLES): Rename from
VM_CHECK_CLOSURE.
(vm_engine, CACHE_PROGRAM): Rename closure and closure_count to free_vars and
free_vars_vount.
* libguile/vm-i-system.c (FREE_VARIABLE_REF): Rename from CLOSURE_REF.
(free-ref, free-boxed-ref, free-boxed-set): Rename from closure-ref,
closure-boxed-ref, closure-boxed-set.
(make-closure): Renamed from make-closure2.
* module/language/glil/compile-assembly.scm (glil->assembly): Hack to
never write out the the old "make-closure" instruction. Will fix
better later. Change to emit free-ref etc instead of closure-ref.
* module/language/tree-il/compile-glil.scm (flatten): Emit make-closure
instead of make-closure2, now that the old make-closure is gone.
* module/system/vm/program.scm (system): Rename program-free-vars to
program-free-variables.
* test-suite/tests/tree-il.test ("lambda"): Update for make-closure.
* module/language/glil.scm (<glil>): New GLIL type, <glil-lexical>,
which will subsume other lexical types.
* module/language/glil/compile-assembly.scm: Compile <glil-lexical>.
(make-open-binding): Change the interpretation of the second argument
-- instead of indicating an "external" var, it now indicates a boxed
var.
(open-binding): Adapt to new glil-bind format.
* module/language/tree-il/analyze.scm: Add a lot more docs.
(analyze-lexicals): Change the allocation algorithm and output format
to allow the tree-il->glil compiler to capture free variables
appropriately and to reference bound variables in boxes if necessary.
Amply documented.
* module/language/tree-il/compile-glil.scm (compile-glil): Compile
lexical variable access to <glil-lexical>. Emit variable capture and
closure creation code here, instead of leaving that task to the
GLIL->assembly compiler.
* test-suite/tests/tree-il.test: Update expected code emission.
* module/language/elisp/README: Document it.
* module/language/elisp/compile-tree-il.scm: Moved ensure-fluid! to runtime function.
* module/language/elisp/runtime.scm: Runtime functions to support dynamic value access.
* module/language/elisp/runtime/function-slot.scm: Defined the built-ins.
* test-suite/tests/elisp-compiler.test: Test them.
* module/language/elisp/README: Document it and some further ideas written down.
* module/language/elisp/compile-tree-il.scm: Implement prog1, dolist.
* module/language/elisp/runtime/macro-slot.scm: prog2 and dotimes.
* test-suite/tests/elisp-compiler.test: Test prog1, prog2, dotimes, dolist.
* libguile/array-handle.c (scm_i_register_array_implementation):
(scm_i_array_implementation_for_obj): Add generic array facility,
which will (in a few commits) detangle the array code.
(scm_array_get_handle): Use the generic array facility. Note that
scm_t_array_handle no longer has ref and set function pointers;
instead it has a pointer to the array implementation. It is unlikely
that code out there used these functions, however, as the supported
way was through scm_array_handle_ref/set_x.
(scm_array_handle_pos): Move this function here from arrays.c.
(scm_array_handle_element_type): New function, returns a Scheme value
representing the type of element stored in this array.
* libguile/array-handle.h (scm_t_array_element_type): New enum, for
generically determining the type of an array.
(scm_array_handle_rank):
(scm_array_handle_dims): These are now just #defines.
* libguile/arrays.c:
* libguile/bitvectors.c:
* libguile/bytevectors.c:
* libguile/srfi-4.c:
* libguile/strings.c:
* libguile/vectors.c: Register array implementations for all of these.
* libguile/inline.h: Update for array_handle_ref/set change.
* libguile/deprecated.h: Need to include arrays.h now.
* 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/elisp/runtime/function-slot.scm: Fixed errors in number preds.
* test-suite/tests/elisp-compiler.test: Test built-ins already implemented.
Thanks to Bill Schottstaedt for reporting this problem!
* libguile/numbers.c (mem2ureal): Don't be misled by *p_exactness
being INEXACT on entry (as is possible when reading a complex
number): use local exactness variable x which starts as EXACT.
Call mem2decimal_from_point () with &x instead of p_exactness.
* test-suite/tests/numbers.test ("string->number"): Add complex number
tests suggested by Bill.
As a side effect, this allows compilation of literal bytevectors
("#vu8(...)"), which gets done by the generic array handling
of the GLIL->assembly compiler.
* doc/ref/api-compound.texi (Generalized Vectors): Mention bytevectors.
(Arrays, Array Syntax): Likewise.
* doc/ref/api-data.texi (Bytevectors as Generalized Vectors): New node.
* libguile/bytevectors.c (scm_i_bytevector_generalized_set_x): New.
* libguile/bytevectors.h (scm_i_bytevector_generalized_set_x): New
declaration.
* libguile/srfi-4.c (scm_i_generalized_vector_type,
scm_array_handle_uniform_element_size,
scm_array_handle_uniform_writable_elements): Add support for
bytevectors.
* libguile/unif.c (type_creator_table): Add `vu8'.
(bytevector_ref, bytevector_set): New functions.
(memoize_ref, memoize_set): Add support for bytevectors.
* libguile/vectors.c (scm_is_generalized_vector,
scm_c_generalized_vector_length, scm_c_generalized_vector_ref,
scm_c_generalized_vector_set_x): Add support for bytevectors.
* test-suite/tests/bytevectors.test ("Generalized Vectors"): New test
set.
* libguile/read.c (scm_read_bytevector): New function.
(scm_read_sharp): Add `v' case for bytevectors.
* test-suite/lib.scm (exception:read-error): New variable.
* test-suite/tests/bytevectors.test ("Datum Syntax"): New test set.
* libguile/bytevectors.c (bytevector_equal_p): New function.
* test-suite/tests/bytevectors.test ("2.3 Operations on Bytes and
Octets")["equal?"]: New test.
Thanks to Greg Troxel for reporting, and Barry Fishman for the
explanation and fix.
* test-suite/tests/popen.test ("open-input-pipe"): Use shell function
`read' with an explicit argument, as apparently not all shells
support read with no argument.
* libguile/load.c (scm_try_autocompile): Punt if compiled-file-name does
not resolve, which would indicate that the file in question is part of
the compiler itself.
* test-suite/tests/elisp.test: Today I was an evil one -- disable
autocompilation for the elisp tests, as they are meant only for the
memoizer's eyes. Hopefully Daniel will fix this :-)
* libguile/threads.c (scm_join_thread_timed): Recheck t->exited before
looping round to call block_self again, in case thread t has now
exited.
* test-suite/tests/threads.test ("don't hang when joined thread
terminates in SCM_TICK"): New test.
* libguile/threads.c (fat_mutex_unlock): Unblock asyncs when breaking
out of loop.
* test-suite/tests/threads.test (asyncs-still-working?): New function,
to test if asyncs are working (i.e. unblocked). Use this throughout
threads.test, in particular before and after the "timed locking
succeeds if mutex unlocked within timeout" test.
* module/language/tree-il/compile-glil.scm (flatten-lambda): Fix source
emission.
* test-suite/tests/tree-il.test (strip-source): Strip source info on
tree-il before compiling, so we don't get extraneous source info in the
glil. Make check passes!
* test-suite/tests/syntax.test ("top-level define"): Remove the test for
currying, as we don't do that any more by default. It should be easy
for the user to add in if she wants it, though.
("do"): Remove unmemoization tests, as sc-expand fully expands `do'.
("while"): Remove while tests in empty environments. They have been
throwing 'unresolved, and the problem they seek to test is fully
handled by hygiene anyway.
And otherwise tweak expected exception strings, and everything passes!
* module/ice-9/boot-9.scm (cond): Implement srfi-61; most of the code is
from the SRFI itself. Yuk.
(%print-module, make-modules-in, %app, (%app modules))
(module-name): Syncase needs to get at the names of modules, even at
anonymous modules. So lazily assign gensyms as module names. Name %app
as (%app), but since (%app modules) is at the top of the module
hierarchy, name it ().
* module/ice-9/psyntax.scm: When building tree-il, try to name lambdas in
definitions and in lets.
(let, letrec): Give more specific errors in a couple of cases.
* module/ice-9/psyntax-pp.scm: Regenerated.
* test-suite/tests/syntax.test: More work. Many exceptions have different
messages than they used to, many more generic; we can roll this back to
be faithful to the original strings, but it doesn't seem necessary to
me.
* module/language/tree-il.scm (tree-il->scheme):
* module/ice-9/psyntax.scm (build-conditional): Attempt to not generate
(if #f #f) as the second arm of an if, but it doesn't seem to be
successful.
* module/ice-9/psyntax-pp.scm (syntax-rules): Regenerate.
* test-suite/tests/syntax.test (exception:unexpected-syntax): Change
capitalization.
("unquote-splicing"): Update test.
("begin"): Add in second arms on these ifs, to avoid the strange though
harmless expansion of `if'.
(matches?): New helper macro.
("lambda"): Match on lexically bound symbols, as they will be
alpha-renamed.
