* 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/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/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.
