* 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/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/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.
