* libguile/vm-i-scheme.c: Add add1 and sub1 instructions.
* module/language/tree-il/compile-glil.scm: Compile 1+ and 1- to add1
and sub1.
* module/language/tree-il/primitives.scm (define-primitive-expander):
Add support for `if' statements in the consequent.
(+, -): Compile (- x 1), (+ x 1), and (+ 1 x) to 1- or 1+ as
appropriate.
(1-): Remove this one. Seems we forgot 1+ before, but we weren't
compiling it nicely anyway.
* test-suite/tests/tree-il.test ("void"): Fix expected compilation of (+
(void) 1) to allow for add1.
* module/language/tree-il/analyze.scm (<binding-info>): New record type.
(report-unused-variables): New procedure.
* module/language/tree-il/compile-glil.scm (%warning-passes): New
variable.
(compile-glil): Honor `#:warnings' from OPTS.
* test-suite/tests/tree-il.test (call-with-warnings): New procedure.
(%opts-w-unused): New variable.
("warnings"): New test prefix.
This adds the 32-bit standalone characters. Strings are still
8-bit. Characters larger than 8-bit can only be entered or
displayed in octal format at this point. At this point, the
terminal's display encoding is expected to be Latin-1.
* module/language/assembly/compile-bytecode.scm (write-bytecode):
add 32-bit char
* module/language/assembly.scm (object->assembly): add 32-bit char
(assembly->object): add 32-bit char
* libguile/vm-i-system.c (make-char32): new op
* libguile/print.c (iprin1): print 32-bit char
* libguile/numbers.h: add type scm_t_wchar
* libguile/numbers.c: add type scm_t_wchar
* libguile/chars.h: new type scm_t_wchar
(SCM_CODEPOINT_MAX): new
(SCM_IS_UNICODE_CHAR): new
(SCM_MAKE_CHAR): operate on 32-bit char
* libguile/chars.c: comparison operators now use Unicode
codepoints
(scm_c_upcase): now receives and returns scm_t_wchar
(scm_c_downcase): now receives and returns scm_t_wchar
* libguile/objcodes.c (OBJCODE_COOKIE): Bump again, as our jump offsets
are now multiplied by 8.
* libguile/vm-i-system.c (BR): Interpret the 16-bit offset as a relative
jump to the nearest 8-byte-aligned block -- increasing relative jump
range from +/-32K to +/-240K.
(mvra): Do the same for the mvra jump.
* libguile/vm.c (really_make_boot_program): Align the mvra.
* module/language/assembly.scm (align-block): New export, for aligning
blocks.
* module/language/assembly/compile-bytecode.scm (write-bytecode): Emit
jumps to the nearest 8-byte-aligned block. Effectively our range is 18
bits in either direction. I would like to do this differently -- have
long-br and long-br-if, and all the other br instructions go to 8 bits
only. But the assembler doesn't have an appropriate representation to
allow me to do this yet, so for now this is what we have.
* module/language/assembly/decompile-bytecode.scm (decode-load-program):
Decode the 19-bit jumps.
* 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/glil/compile-assembly.scm (glil->assembly)
(dump-object): Fix an exciting bug! Subprograms of subprograms were
not being aligned correctly, because the code was generated too early.
So instead delay dumping the object table until the proper time.
* libguile/vm-i-system.c (long-local-ref, long-local-set)
(make-variable): New intructions, for handling nlocs >= 256.
* module/language/glil/compile-assembly.scm (glil->assembly): Compile
<glil-lexical> with support for nlocs >= 256.
* 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.
* 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.
* libguile/frames.c (scm_frame_external_link): Removed.
* libguile/frames.h: No need to have the "external link" in the stack
frame -- update macros to take the new situation into account.
* libguile/objcodes.h (struct scm_objcode): Rename the nexts field to
"unused". In the future we can use it for nlocs, I think.
(SCM_OBJCODE_NEXTS): removed.
* libguile/programs.h:
* libguile/programs.c (scm_make_program): Expect the third argument to
be a vector of free variables, not a list of free variables.
SCM_BOOL_F indicates no free variables, not SCM_EOL.
(program_mark): Adapt.
(scm_program_arity): No more nexts.
(scm_program_free_vars): Replaces scm_program_externals.
* libguile/vm-engine.c (VM_CHECK_EXTERNAL)
(vm_engine): No need for the "external" var.
* libguile/vm-engine.h (CACHE_PROGRAM): Update for SCM_PROGRAM_FREE_VARS
instead of SCM_PROGRAM_EXTERNALS.
(NEW_FRAME): Update for new frame size, and no need to cons up
externals. Yay :)
* libguile/vm-i-loader.c (load-program): Update for scm_make_program.
* libguile/vm-i-system.c (external-ref, external-set): No more.
(make-closure): No more.
(goto/args): No need to re-cons externals here. Update for new stack
frame size.
(mv-call, return, return/values): Update for new frame size. No need
to reinstate externals on return.
* libguile/vm.c (really_make_boot_program, scm_load_compiled_with_vm):
Update for scm_make_program.
* module/language/objcode/spec.scm (objcode-env-externals): Treat '() as
#f, for the externals. Need to clean this up later...
* module/system/vm/program.scm (arity:nexts): Remove. Rename
program-external to program-free-vars.
* 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.
* libguile/instructions.c (scm_instruction_list): Fix a longstanding bug
in this humble function.
* libguile/vm-i-scheme.c (BV_FIXABLE_INT_SET, BV_INT_SET, BV_FLOAT_SET):
Fix some bugs in these macros -- now the bytevector ops work.
* module/language/tree-il/compile-glil.scm (*primcall-ops*): Compile
bytevector calls to VM ops.
* module/language/tree-il/primitives.scm
(*interesting-primitive-names*): Resolve bytevector calls to primitive
calls.
* module/language/tree-il/primitives.scm
(*interesting-primitive-names*): Resolve vector-ref and vector-set!.
* module/language/tree-il/compile-glil.scm (*primcall-ops*): And compile
vector-ref and vector-set! to their opcodes.
* libguile/vm-i-scheme.c (vector-ref, vector-set): New opcodes, placed
before the bytevector ops. The renumbering shouldn't affect anyone,
given that the bytevector ops were not yet used. Fix a few bugs in the
bytevector ops.
* libguile/objcodes.c (OBJCODE_COOKIE): Bump the objcode cookie. We'll
be doing this on incompatible changes until 2.0.
* libguile/vm-i-scheme.c (set_car, set_cdr, slot_set): These
instructions don't have natural return values -- so declare them that
way, that they push 0 values.
* module/language/tree-il/compile-glil.scm (flatten): When compiling
primitive calls, check `(instruction-pushes op)' to see how many
values that instruction will push, and do something appropriate,
instead of just assuming that all primcall ops push 1 value.
* module/language/brainfuck/compile-tree-il.scm (compile-tree-il):
Remove the hack where we wrapped the compiled code in a `lambda',
because not only should the tree-il compiler optimize that away, it
was really papering around other inefficiencies, and obtuse to boot.
* module/language/brainfuck/compile-tree-il.scm (compile-tree-il): Wrap
the result in a ((lambda () ...)), so we can use toplevel-ref. Add
lots more comments.
* module/Makefile.am (BRAINFUCK_LANG_SOURCES): Compile at the end. Add
compile-tree-il.scm.
* module/language/brainfuck/compile-tree-il.scm: New compiler, compiles
to tree-il instead of scheme. I thought it would be more illustrative,
though there are some uncommented bits.
* module/language/brainfuck/parse.scm: Modify not to put a header on the
scheme representation. After all, we don't put <scheme> before scheme
code, do we? :)
* module/language/brainfuck/spec.scm: Add tree-il compiler.
* module/language/tree-il.scm: Understand (set! (lexical foo) ...).
* module/system/base/language.scm: Update license. Actually, updates
licenses on all these.
* doc/ref/compiler.texi: Mention the new brainfuck compiler as an example.
* module/language/brainfuck/compile-scheme.scm: Add a lot of documentation comments.
* module/language/brainfuck/parse.scm: Ditto.
* module/language/brainfuck/spec.scm: Ditto.
* module/Makefile.am: Install the brainfuck compiler modules.
* module/language/brainfuck/spec.scm: New file.
* module/language/brainfuck/parse.scm: New file.
* module/language/brainfuck/compile-scheme.scm: New file.
This allows, e.g., ",c #u8(1 2 3)" at the REPL to actually work instead
of failing to decode `load-array'.
* module/language/assembly/decompile-bytecode.scm (decode-bytecode):
Account for the `load-array' instruction, which is followed by a
bytevector instead of a string. We should find a more elegant way to
do that.
* module/language/ecmascript/compile-ghil.scm (comp): Just use pmatch,
not ormatch. Now with syncase running over everything, it doesn't
matter.
* module/ice-9/boot-9.scm (false-if-exception): Avoid saving stacks
inside false-if-exception. There's probably a more general solution to
this, though. Fixes getting bogus backtraces sometimes.
* module/Makefile.am (ECMASCRIPT_LANG_SOURCES): Reorder things so that
spec comes last.
* module/language/tree-il.scm: Rename let-exp and letrec-exp to let-body
and letrec-body. Add <let-values>, a one-expression let-values that
should avoid the needless creation of two closures in many common
multiple-value cases. We'll need to add an optimization pass to the
compiler to produce this form, though, as well as rewriting lambdas
into lets, etc.
I added this form instead of adding more special cases to the
call-with-values compile code because it's a useful intermediate form
-- it will allow the optimizer to perform constant folding across more
code.
* module/language/tree-il.scm (parse-tree-il, unparse-tree-il)
(tree-il->scheme, post-order!, pre-order!): Adapt to let/letrec body
renaming, and let-values.
* module/language/tree-il/analyze.scm (analyze-lexicals): Adapt for
renaming, and add cases for let-values.
* module/language/tree-il/compile-glil.scm (flatten): Add a new context,
`vals', used by let-values code for the values producer. Code that
produces multiple values can then jump to the let-values MV return
address directly, instead of trampolining into a procedure. Add code to
compile let-values.
* libguile/vm-i-scheme.c (FUNC2): Use a signed value for the intermediate
result here. Not sure what the effect is, though.
* module/ice-9/psyntax.scm (chi-top): Toplevel definitions ensure that
variables are defined in the current module. Fixes the specific case of
guile-lib's md5.scm, which redefines + -- this code is needed so that
we don't incorrectly open-code +.
* module/language/tree-il/primitives.scm (resolve-primitives!): I think
there were some cases in which vars and names would not resolve
properly here. Fix those.
* doc/ref/vm.texi (Loading Instructions): Remove references to
load-integer and load-unsigned-integer -- they're still in the VM but
will be removed at some point.
(Data Control Instructions): Add make-int64 and make-uint64.
* libguile/vm-i-loader.c (load-unsigned-integer): Allow 8-byte values.
But this instruction is on its way out, yo.
* libguile/vm-i-system.c (make-int64, make-uint64): New instructions.
* module/language/assembly.scm (object->assembly): Write out make-int64
and make-uint64 instructions, using bytevectors to do the endianness
conversion.
(assembly->object): And pretty-print them back, for disassembly.
* module/language/glil/compile-assembly.scm: Don't generate load-integer
/ load-unsigned-integer instructions.
* module/rnrs/bytevector.scm (rnrs):
* libguile/bytevectors.h:
* libguile/bytevectors.c (scm_uniform_array_to_bytevector): New function.
* libguile/unif.h:
* libguile/unif.c (scm_from_contiguous_typed_array): New function.
* libguile/vm-i-loader.c (load-array): New instruction, for loading byte
data into uniform vectors. Currently it copies out the data, though in
the future we could avoid that.
* module/language/assembly.scm (align-code): New exported function,
aligns code on some boundary.
(align-program): Use align-code.
* module/language/assembly/compile-bytecode.scm (write-bytecode): Support
the load-array instruction.
* module/language/glil/compile-assembly.scm (dump-object): Dump uniform
arrays. Neat :)
* libguile/vm-i-system.c (long-object-ref, long-toplevel-ref)
(long-toplevel-set): Add new instructions, for accessing the object
table with a 16-bit offset. HTMLprag defines a test program that has
more than 256 constants, necessitating this addition.
* doc/ref/vm.texi: Mention the new instructions.
* module/language/glil/compile-assembly.scm: Emit long refs for object
tables bigger than 256 entries.
* doc/ref/api-procedures.texi (Compiled Procedures): Fix for API changes.
* doc/ref/compiler.texi (Compiling to the Virtual Machine): Replace GHIL
docs with Tree-IL docs. Update the bits about the Scheme compiler to
talk about Tree-IL and the expander instead of GHIL. Remove
<glil-argument>. Add placeholder sections for assembly and bytecode.
* doc/ref/vm.texi: Update examples with what currently happens. Reword
some things. Fix a couple errors.
* libguile/vm-i-system.c (externals): Remove this instruction, it's not
used.
* module/ice-9/documentation.scm (object-documentation): If the object is
a macro, try to return documentation on the macro transformer.
* module/language/assembly/disassemble.scm (disassemble-load-program):
Fix problem in which we skipped the first element of the object vector,
because of changes to procedure layouts a few months ago.
* module/language/scheme/spec.scm (read-file): Remove read-file
definition.
* module/language/tree-il.scm: Reorder exports. Remove <lexical>, it was
a compat shim to something that was never released. Fix `location'.
* module/language/tree-il/primitives.scm (/): Fix expander for more than
two args to /.
* module/system/base/compile.scm (read-file-in): Remove unused
definition.
* module/system/base/language.scm (system): Remove language-read-file.
* module/language/ecmascript/spec.scm (ecmascript): Remove read-file
definition.
* module/language/tree-il/optimize.scm:
* module/language/tree-il/primitives.scm: Move primitive-related things
to primitive.scm from inline.scm and optimize.scm.
* module/Makefile.am: Update for inventory changes.
* 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!
* module/language/tree-il/compile-glil.scm (flatten-lambda): Fix bad call
to make-glil-src, unfortunately not hit during production because
psyntax doesn't yet understand source locations.
* 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.
* module/language/tree-il/compile-glil.scm (flatten): Actually apply only
needs one arg after the proc. And shit, call/cc and apply in drop
contexts also need to be able to return arbitrary numbers of values;
work it by trampolining through their applicative (non-@) definitions.
Also, simplify the single-valued drop case to avoid the
truncate-values.
* module/language/tree-il/inline.scm (call/cc):
* module/language/tree-il/optimize.scm (*interesting-primitive-names*):
Define call/cc as "interesting". Perhaps we should be hashing on value
and not on variable.
* test-suite/tests/tree-il.test ("application"): Fix up test for new,
sleeker output. (Actually the GLIL is more verbose, but the assembly is
better.)
("apply", "call/cc"): Add some more tests.
* module/language/tree-il/compile-glil.scm (flatten): For applications in
"drop" context, allow the procedure to return unspecified values
(including 0 values).
* test-suite/tests/tree-il.test ("application"): Adapt test.
* module/srfi/srfi-18.scm (wrap): Clarify.
* test-suite/tests/srfi-18.test: Fix so that the expression importing
srfi-18 is expanded before the tests. However the tests are still
failing, something about 0-valued returns...
* module/ice-9/boot-9.scm (guile-user): Move the `compile' autoload to
the guile-user module. Remove reference to compile-time-environment.
* module/language/scheme/compile-ghil.scm:
* module/language/tree-il/compile-glil.scm:
* module/language/tree-il/optimize.scm:
* module/system/base/compile.scm:
* test-suite/tests/compiler.test: Remove definition of and references to
compile-time-environment. While I do think that recompilation based on
a lexical environment can be useful, I think it needs to be implemented
differently. So for now we've lost nothing if we take it away, as it
doesn't work with syncase anyway.
* module/language/tree-il/compile-glil.scm: Add primcall compilers for
@slot-ref and @slot-set.
* module/language/tree-il/optimize.scm (add-interesting-primitive!): New
export. Creates an association between a variable in the current module
and a primitive name.
* module/oop/goops.scm: Rework compiler hooks to work with tree-il and
not ghil.
* module/language/glil/compile-assembly.scm (glil->assembly): Check the
length when emitting calls to variable-argument stack instructions.
Allow two-byte lengths -- allows e.g. calls to `list' with more than
256 arguments.
* module/language/tree-il/compile-glil.scm: Add primcall associations for
`list' and `vector', with any number of arguments. Necessary because
syncase's quasiquote expansions will produce calls to `list' with many
arguments.
* module/language/tree-il/optimize.scm (*interesting-primitive-names*):
Add `list' and `vector' to the set of primitives to resolve.
* module/language/tree-il/analyze.scm (analyze-lexicals): Add in a hack
to avoid allocating more locals than necessary for expansions of `or'.
Documented in the source.
* test-suite/tests/tree-il.test: Add a test case.
* module/ice-9/psyntax.scm (chi-install-global, syntax-case): Fix a
couple of cases in which bare datums were passed to output
constructors.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/language/scheme/spec.scm (scheme): Clean up the #:compilers
list.
* module/language/tree-il/compile-glil.scm (flatten): Fix call to
`length' in call/cc compiler.
* libguile/vm-i-system.c:
* libguile/vm-engine.h (ASSERT_BOUND): New assertion, that a value is
bound. Used by local-ref and external-ref in paranoid mode.
* module/ice-9/boot-9.scm (and, or, cond, case, do): Since we are
switching to use psyntax as the first pass of the compiler, and perhaps
soon of the interpreter too, we need to make sure it expands out all
forms to primitive expressions. So define expanders for these derived
syntax forms, as in the R5RS report.
* module/ice-9/psyntax-pp.scm: Regenerate, with core forms fully
expanded.
* module/ice-9/psyntax.scm (build-void): New constructor, for making
undefined values.
(build-primref): Add in a hack so that primitive refs in the boot
module expand out to toplevel refs, not module refs.
(chi-void): Use build-void.
(if): Define an expander for if that calls build-conditional.
* module/language/scheme/compile-tree-il.scm (compile-tree-il): Use let*
so as not to depend on binding order for the result of
(current-module).
* module/language/scheme/spec.scm (scheme): Switch over to tree-il as the
primary intermediate language. Not yet fully tested, but at least it
can compile psyntax-pp.scm.
* module/language/tree-il/analyze.scm (analyze-lexicals): Arguments don't
count towards a function's nlocs.
* module/language/tree-il/compile-glil.scm (*comp-module*, compile-glil):
Define a "compilation module" fluid.
(flatten-lambda): Fix a call to make-glil-argument. Fix bug in
heapifying arguments.
(flatten): Fix number of arguments passed to apply instruction. Add a
special case for `(values ...)'. If inlining primitive-refs fails,
try expanding into toplevel-refs if the comp-module's variable is the
same as the root variable.
* module/language/tree-il/optimize.scm (resolve-primitives!): Add missing
src variable for <module-ref>.
* test-suite/tests/tree-il.test ("lambda"): Fix nlocs counts. Add a
closure test case.
* 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.
* module/language/tree-il/compile-glil.scm (flatten): Handle a number of
interesting applications, and fix a bug for calls in `drop' contexts.
* module/language/tree-il/inline.scm: Define expanders for apply,
call-with-values, call-with-current-continuation, and values.
* module/system/base/pmatch.scm: Wrap consequents in (let () ) instead of
(begin ) so that they can have local definitions.
* module/language/tree-il/compile-glil.scm: Inline some calls to
primitives.
* module/ice-9/boot-9.scm (delay): Define `delay' in terms of
make-promise.
* module/ice-9/psyntax-pp.scm (compile): Regenerated with a fully
compiled Guile, so that the gensym numbers are the same.
* module/language/tree-il/compile-glil.scm: Add some notes about what
needs doing to catch up to the old compiler.
