* 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.
* 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/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.
