* module/language/cps/effects-analysis.scm (string-ref): Remove effects
declaration, given that the primitive is exploded now.
* module/language/cps/reify-primitives.scm (compute-known-primitives):
Add string-set!.
* libguile/vm-engine.c (string-set!): Disable opcode.
* module/language/cps/types.scm (string-ref, string-set!): Remove type
checker and inferrers for string-ref and string-set!, as both are
exploded. In the case of string-set! there are still type-check
effects in the intrinsic call but they can't be elided by the checker,
as we don't track when strings are read-only.
* module/language/tree-il/compile-cps.scm (ensure-char): New helper.
(string-set!): New primcall exploded converter.
* module/language/cps/types.scm (annotation->type):

Add case for string memory kinds. Remove special type and effect
inferrers for string-length.

Remove string-length.
* module/language/tree-il/compile-cps.scm (ensure-string): New helper.
(string-length): Add custom converter.
* module/language/cps/reify-primitives.scm (compute-known-primitives):
Treat add, sub, and so on as known primitives.
* libguile/vm-engine.c: Remove code for now-unused instructions.
* libguile/intrinsics.h: Rename intrinsic types added in previous
commit.
* libguile/vm-engine.c (call-scm<-scm-scm, call-scm<-scm-uimm): New
instructions.
* libguile/vm.c: Include intrinsics.h.
* module/language/bytecode.scm
* module/language/bytecode.scm (*intrinsic-codes*, *intrinsic-names*):
New internal definitions.

definitions.

helpers. Define encoders for "add", etc.

* module/language/tree-il/peval.scm (peval)[lift-applied-lambda]: Before
performing eta-conversion, check that the variable(s) passed to the
inner 'apply' are not referenced from the inner lambda, and that the
number of required arguments would not be reduced by the conversion.
* module/system/base/target.scm (cpu-endianness): Add case for "riscv" variants.

This is a followup to <https://bugs.gnu.org/29704>.
* module/srfi/srfi-18.scm (thread-sleep!): When TIMEOUT is a number,
keep it as-is.
* test-suite/tests/srfi-18.test ("thread sleep with number"): Pass 0 as
the timeout.
("thread sleeps fractions of a second"): Pass 0.5 as the timeout.
Fixes <https://bugs.gnu.org/29704>.

* test-suite/tests/srfi-18.test ("mutex-lock! returns false on timeout")
("mutex-lock! returns true when lock obtained within timeout")
("recursive lock waits")
("mutex unlock is false when condition times out"): Adjust cases where
the 'timeout' parameter is a number so that it's a relative number.

make-struct/simple, so we can inline allocations.
* module/ice-9/psyntax-pp.scm: Regenerate.

&bitmask, for the bitmask in vtables.
(annotation->memory-kind): Add 'bitmask case.

you know the length is less than 2**48.
* module/language/cps/compile-bytecode.scm (compile-function): Fix
emitters for u64-set! et al.

lowering to CPS.
