* module/language/tree-il/primitives.scm (*interesting-primitive-names*):
(*effect-free-primitives*): Recognize keyword->symbol, symbol->keyword.
* module/language/tree-il/cps-primitives.scm: Plumb through to CPS.
(keyword->symbol):
* module/language/cps/effects-analysis.scm: New prims have no effect.
Fix effects for string->symbol.
(annotation->memory-kind): Add keywords.
* module/language/cps/guile-vm/lower-primcalls.scm (keyword->symbol):
Lower to scm-ref/immediate.
* module/language/cps/types.scm (annotation->type): Add case for
keywords.
* module/language/tree-il/compile-cps.scm: Add converters for new prims,
with type guards.
These numeric predicates now have CPS branching primcalls, which allows
type inference and folding to reduce them to less-strong instructions.
* module/language/cps/effects-analysis.scm (heap-numbers-equal?): Put
all the number predicates together. None have type checks.
* module/language/cps/guile-vm/lower-primcalls.scm
(define-branching-primcall-alias): New helper.
(complex?): Same as number?.
* module/language/cps/guile-vm/lower-primcalls.scm (real?)
(rational?, integer?, exact-integer?, exact?, inexact?): Define
lowerers.
* module/language/cps/type-fold.scm (number?, complex?, real?)
(rational?, integer?, exact-integer?, exact?, inexact?): Add folders and
reducers for all of these.
* module/language/cps/type.scm (number?, complex?, real?)
(rational?, integer?, exact-integer?, exact?, inexact?): Add type
inference for these.
* module/language/tree-il/compile-cps.scm (convert): Add number? checks
before exact? and inexact?. Remove the eager lowering of
exact-integer?; instead rely on folders.
* module/language/tree-il/cps-primitives.scm (number?, complex?)
(real?, rational?, integer?, exact-integer?, exact?, inexact?): Add
primitive decls. Define as "number-type-predicates?", meaning they need
a number? guard.
* module/language/cps/effects-analysis.scm: Mark more predicates as
effect-free. Sort the list.
* module/language/cps/guile-vm/lower-primcalls.scm (procedure?): Reify a
call to a primitive. Sadly we can't elide the $kreceive, as even though
we know that it's single-valued, $call can't continue to $kargs (has to
be $callk). Perhaps is worth relaxing in the future.
* module/language/cps/type-fold.scm: Define a number of additional
folders for disjoint types.
(procedure?): Define a folder for &procedure. Has to include structs,
though.
* module/language/cps/types.scm: Same as for type-fold.scm.
* module/language/tree-il/cps-primitives.scm: Lower procedure? primcalls
to CPS.
* module/language/cps/closure-conversion.scm (convert-one): Add nfree to
the param. This will help the wasm target.
* module/language/cps/effects-analysis.scm (closure-ref, closure-set!):
* module/language/cps/lower-primcalls.scm (closure-ref,closure-set!):
Adapt.
* module/system/base/target.scm (target-runtime): New export.
* module/language/cps/optimize.scm (make-cps-lowerer): Load a
backend-specific lowering module dynamically.
* module/language/cps/guile-vm.scm: New module for lowering to Guile's
VM.
* module/language/cps/guile-vm/loop-instrumentation.scm:
* module/language/cps/guile-vm/lower-primcalls.scm:
* module/language/cps/guile-vm/reify-primitives.scm: Move here, from
parent dir.
* am/bootstrap.am: Update for new file list.
