* 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.
* 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/oop/goops.scm (method): Reimplement as a hygienic macro. This
seriously took me like 6 hours to figure out. Allows for lexical
specializers: (let ((<x> ...)) (define-method (foo (arg <x>)) ...)).
* module/oop/goops/compile.scm (next-method?, compile-make-procedure):
Remove these, as `method' does it all now, hygienically.
* libguile/posix.c: Always use <sys/file.h>, which is provided by
Gnulib.
(flock)[__MINGW32__]: Remove.
(scm_flock): Compile unconditionally. Always use Gnulib's flock(2).
* m4/gnulib-cache.m4 (gl_MODULES): Add `flock' (provides flock(2)
declaration and implementation), `fpieee' (fixes floating point
behavior on Alpha and SH), `stdlib' (provides an unsetenv(3)
declaration, among others), `putenv' (provides a putenv(3) declaration
and implementation with the semantics we need).
* test-suite/tests/reader.test ("read-options"): Add test
for long postfix keywords.
* libguile/read.c (scm_read_mixed_case_symbol): Fix
exception on symbols are greater than 128 chars. Also,
colons are not stripped from long postfix keywords.
* test-suite/standalone/test-round.c (HAVE_MACHINE_FPU_H): Include
<sys/types.h> when available. This fixes compilation on NetBSD.
Reported by Greg Toxel.
* test-suite/standalone/test-conversion.c (ieee_init): New function.
(guile_Inf, guile_NaN): New variables.
(test_from_double, test_to_double): Use them. Divisions by zero made
`cc' on Tru64 5.1b ("Compaq C V6.5-011") bail out and led to a
floating point exception when compiled with GCC on the same platform.
(main): Call `ieee_init ()'.
* test-suite/standalone/test-conversion.c: Remove extraneous semicolon
following `DEF[SU]TST' invocations since that made Compaq C
V6.5-011 (`cc' on Tru64 5.1b) bail out.
On the one hand we want the child process in these tests to exit. On
the other, we don't want it to exit before the parent Guile code has
tested the relevant condition (EOF in the first test, broken pipe in
the second) - because these conditions would obviously be true if the
child had already exited, and that's not what we're trying to test
here. We're trying to test getting EOF and broken pipe while the
child process is still alive.
* test-suite/tests/popen.test (open-input-pipe:no duplicate): Add
another pipe from parent to child, so that the child can finish by
reading from this. Then the parent controls the child lifetime by
writing to this pipe.
* test-suite/tests/popen.test (open-output-pipe:no duplicate): Add
another pipe from child to parent, and have the child finish by
endlessly writing into this. Then the parent controls the child
lifetime by closing its end of the pipe, causing a broken pipe in
the child.
* module/ice-9/psyntax.scm (chi-lambda-clause): Strip the docstring
before passing it on to the continuation.
* module/ice-9/psyntax-pp.scm: Regenerated.
* test-suite/tests/eval.test (exception:failed-match): New exception, for
syntax-case failed matches.
("evaluator"): Fix macro-as-parameter tests. They pass now :)
* 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.
* testsuite/t-match.scm (matches?): Fix match invocation. As far as I can
tell, although (ice-9 match) does advertise a => form of clauses, it
requires that the end of the => be a symbol. For some reason this
works in the interpreter:
((lambda () (begin => #t)))
It's part of the expansion of matches?. It also worked in the old
compiler. Thinking that maybe toplevel references could cause side
effects, I made the new compiler actually ref =>, which brought this to
light.
* 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.
* module/language/tree-il/compile-glil.scm (vars->bind-list)
(emit-bindings, flatten-lambda, flatten): Write the original names into
<glil-bind> structures. Yaaaaay!
* module/ice-9/psyntax.scm (build-lambda, build-let, build-named-let)
(build-letrec): Actually pass along the original ids to tree-il
constructors.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/language/tree-il.scm: Add fields in <lambda>, <let>, and
<letrec> for the original variable names.
* module/language/tree-il/compile-glil.scm (compile-glil): Adapt for new
make-lambda arg.
* module/ice-9/psyntax.scm (build-letrec, build-let, build-lambda)
(build-named-let): Take extra args for the original names of the
gensyms. Not used yet. Callers adapted.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/language/tree-il/analyze.scm: Break analyzer out into its own
file.
* module/language/tree-il/compile-glil.scm: Port the GHIL->GLIL compiler
over to work on tree-il. Works, but still misses a number of important
optimizations.
* module/language/tree-il.scm: Add <void>. Not used quite yet.
* module/language/glil.scm: Remove <glil-argument>, as it is the same as
<glil-local> (minus an offset).
* module/language/glil/compile-assembly.scm:
* module/language/glil/decompile-assembly.scm:
* module/language/ghil/compile-glil.scm: Adapt for <glil-argument>
* removal.
* module/Makefile.am (TREE_IL_LANG_SOURCES): Reorder, and add
analyze.scm.
* module/language/tree-il/optimize.scm: Rework to just export the
optimize! procedure.
* module/language/tree-il/compile-glil.scm (analyze-lexicals): New
function, analyzes and allocates lexical variables. Almost ready to
compile now.
(codegen): Dedent.
* module/Makefile.am: Add inline.scm.
* module/language/tree-il.scm (pre-order!, post-order!): pre-order! is
new. post-order! existed but was not public. They do destructive tree
traversals of tree-il, and need more documentation. Also, add
predicates to tree-il's export list.
* module/language/tree-il/inline.scm: New file, which expands primitives
into more primitive primitives. In the future perhaps it will not be
necessary, as the general inlining infrastructure will handle these
cases, but for now it's useful.
* module/language/tree-il/optimize.scm: Move post-order! out to better
pastures.
* module/language/tree-il/optimize.scm: New module, for optimizations.
Currently all we have is resolving some toplevel refs to primitive
refs.
* module/Makefile.am: Add new module.
* module/language/tree-il.scm: Fix exports for accessors for `src'.
* module/language/tree-il/compile-glil.scm: Tweaks, things still aren't
working yet.
* module/language/scheme/amatch.scm: Remove, this approach won't be used.
* module/Makefile.am: Adjust for additions and removals.
* module/language/scheme/compile-ghil.scm: Remove an vestigial debugging
statement.
* module/language/scheme/spec.scm:
* module/language/scheme/compile-tree-il.scm:
* module/language/scheme/decompile-tree-il.scm: Add tree-il compiler and
decompiler.
* module/language/tree-il/compile-glil.scm: Add some notes.
* module/language/tree-il/spec.scm: No need to wrap expressions in
lambdas -- GHIL needs somewhere to put its variables, we don't.
* module/Makefile.am: Add tree-il sources.
* module/ice-9/compile-psyntax.scm: Adjust for sc-expand producing
tree-il in compile mode.
* module/ice-9/psyntax.scm: Switch from expand-support to tree-il for
generating output in compile mode. Completely generate tree-il -- the
output wasn't Scheme before, but now it's completely not Scheme.
* module/ice-9/psyntax-pp.scm: Regenerated.
* module/language/scheme/compile-ghil.scm: Strip structures using
tree-il, not expand-support.
* module/language/tree-il.scm:
* module/language/tree-il/spec.scm
* module/language/tree-il/compile-glil.scm: New language. It will compile
to GLIL, though it doesn't yet.
