* module/language/cps/closure-conversion.scm: Use standard
compute-reachable-functions and intmap-select from utils to filter
reachable functions, allowing us to pick up callk. Adapt some uses to
expect callk for calls.
* module/language/cps/self-references.scm (resolve-self-references):
Subst the proc, if it's there.
* module/language/cps/split-rec.scm (compute-free-vars): Add a case for
callk.
* module/language/cps/closure-conversion.scm (compute-elidable-closures):
New function.
(convert-one, convert-closures): Add ability to set "self" variable of
$kfun to $f, hopefully avoiding passing that argument in some cases.
* module/language/cps/compile-bytecode.scm (compile-function): Pass the
has-closure? bit on through to the assembler.
* module/system/vm/assembler.scm (begin-standard-arity)
(begin-opt-arity, begin-kw-arity): Only reserve space for the closure
as appropriate.
* module/language/cps/slot-allocation.scm (allocate-args)
(compute-defs-and-uses, compute-needs-slot)
(compute-var-representations): Allow for closure slot allocation
differences.
* module/language/cps/cse.scm (compute-defs):
* module/language/cps/dce.scm (compute-live-code):
* module/language/cps/renumber.scm (renumber, compute-renaming):
(allocate-args):
* module/language/cps/specialize-numbers.scm (compute-significant-bits):
(compute-defs):
* module/language/cps/split-rec.scm (compute-free-vars):
* module/language/cps/types.scm (infer-types):
* module/language/cps/utils.scm (compute-max-label-and-var):
* module/language/cps/verify.scm (check-distinct-vars):
(compute-available-definitions): Allow closure to be #f.
* module/language/cps.scm ($branch): Refactor to be its own CPS term
type, not relying on $continue to specify a continuation (which before
was only for the false case) or a source location. Update allllllll
callers.
* module/language/cps.scm ($primcall): Add "param" member, which will be
a constant parameter to the primcall. The idea is that constants used
by primcalls as immediates don't need to participate in optimizations
in any way -- they should not participate in CSE, have the same
lifetime as the primcall so not part of DCE either, and don't need
slot allocation. Indirecting them through a named $const binding is
complication for no benefit. This change should eventually improve
compilation time and memory usage, once we fully take advantage of it,
as the number of labels and variables will go down.
