* module/language/cps/effects-analysis.scm (&memory-kind-mask): Add
&bitmask, for the bitmask in vtables.
(annotation->memory-kind): Add 'bitmask case.
* module/language/tree-il/compile-cps.scm (ensure-struct-index-in-range):
(prepare-struct-scm-access): New helpers.
(struct-ref/immediate, struct-set!/immediate): New exploded lowering
routines.
(struct-ref, struct-set!): New lowering routines that just do a call.
(canonicalize): Remove struct-ref hack; lowering procedures will
handle it.
* module/language/tree-il/cps-primitives.scm (bytevector-length): Define
struct-set! as returning a value.
* module/language/tree-il/cps-primitives.scm (allocate-vector)
(vector-init!): Declare these primitives which later go away when
lowering to CPS.
* module/language/tree-il/compile-cps.scm (vector-init!): New
converter.
(allocate-vector): New converter.
* module/language/tree-il/cps-primitives.scm: New file,
replacing (language cps primitives). Lists known primitives and their
relation to Tree-IL explicitly, instead of assuming that any Tree-IL
primcall that shares a name with a bytecode instruction is a CPS
primcall.
* module/language/cps/verify.scm: Remove use of (language cps
primitives) and primcall arity checking. Would be nice to add this
back at some point.
* module/language/tree-il/compile-cps.scm (convert): Refactor to use new
tree-il-primitive->cps-primitive+nargs+nvalues helper.
* module/Makefile.am:
* am/bootstrap.am: Adapt.
