On Windows, deleting a file on an open port does not succeed
* test-suite/tests/ports.test ("%default-port-encoding, wrong encoding"):
ensure port is closed before deleting
* configure.ac (AC_CHECK_FUNCS): add mkdtemp! test
* doc/ref/posix.texi: document mkdtemp!
* libguile/filesys.c (scm_mkdtemp_x): new function
* libguile/filesys.h: new declaration for scm_mkdtemp_x
* test-suite/tests/filesys.test: add tests for mkdtemp!
Adapted from a patch by Rob Browning.
The underlying function was moved to filesys.c in
073167ef7b but the declaration didn't follow
* libguile/filesys.h: add declaration for scm_mkstemp
* libguile/posix.h: remove declaration for scm_mkstemp
* libguile/r6rs-ports.c (scm_i_make_transcoded_ports): make sure to
include SCM_RDNG for input/output ports.
Thanks to Göran Weinholt for reporting the problem.
Closes: 41045
* module/scheme/base.scm (member): Match the r7rs requirement, as assoc
already does.
Thanks to Erik Dominikus for reporting the problem.
Closes: 43304
The line, part of the sentence above it in a comment, was accidentally
removed in commit b8d757732f "Rationalize
include order in C files".
* libguile/guile.c: restore missing line.
[rlb@defaultvalue.org: augment commit message; add THANKS]
Closes: 42331
* libguile/srfi-13.c (scm_reverse_list_to_string): Replace string->list
with list->string in the composition explaning how it works. Thanks
to Andrey Ivanov for reporting the problem.
Closes: 34457
* module/rnrs/io/ports.scm (call-with-port): Remove local definition.
* module/system/repl/server.scm (system): Call-with-port is imported
via (ice-9 ports).
* module/ice-9/binary-ports.scm (call-with-input-bytevector):
(call-with-output-bytevector): New functions.
* module/ice-9/iconv.scm: Remove superfluous copies of
call-with-output-string* and call-with-output-bytevector*, now that
the former closes the port and the latter exists.
(call-with-encoded-output-string): Adapt.
* module/web/uri.scm: Use (ice-9 iconv) instead of local
bytevector/string conversion procedures.
* module/ice-9/ports.scm (call-with-port): New procedure, from r7rs.
(call-with-input-file, call-with-output-file): Refactor to use
call-with-port.
(call-with-output-string): Close the string after normal exit.
* module/scheme/base.scm (scheme): Re-export call-with-port from base.
* lightening/x86.c (jit_try_shorten): If the address is within the
last instruction, don't shorten. If the intstruction is a jump, we
could elide it entirely in some cases, but we don't know if the user
captured the PC before calling jit_patch_here. Better to leave this
to the user.
Thanks to Helmut Eller for the bug report and test case in
https://gitlab.com/wingo/lightening/-/issues/17.
* module/ice-9/boot-9.scm (%auto-compilation-options): Add
use-before-definition and non-idempotent-definition.

analysis info.
(make-use-before-definition-analysis): New function.
(goops-toplevel-definition): Move down.
(unbound-variable-analysis, macro-use-before-definition): Remove, as
they are subsumed by use-before-def. There are some deprecated
bindings though.
(make-analyzer): Rework to allow for use-before-def analysis to handle
multiple
* module/system/base/message.scm (%warning-types): Add handlers for the
new warning types.
* test-suite/tests/tree-il.test: Add tests.
* doc/ref/api-evaluation.texi (Compilation): Update.
* libguile/gc.c (DEFAULT_INITIAL_HEAP_SIZE): Bump a bit farther (2 MB on
64-bit, 1 MB on 32-bit) as we now expand to this size instead of
expanding by this amount.
(scm_storage_prehistory): Expand to the initial heap size instead of
expanding by the size.
* libguile/gc.c (DEFAULT_INITIAL_HEAP_SIZE): Bump to 1.6 MB on 64-bit
targets, or 800 kB on 32-bit targets, to account for increased
footprint. Prevents useless early GC.
(scm_storage_prehistory): Remove unused code to dynamically change the
free space divisor.
* libguile/loader.h (SCM_OBJCODE_MINOR_VERSION): Accept up to version 4.
* module/system/vm/assembler.scm (*bytecode-minor-version*): Produce
version 4.

to replace manual uses.

helpers.
(compute-consts): New function, to compute constants at each label,
using not only definitions but flow.
(<analysis>): Add consts to analysis.
(elide-predecessor, prune-branch, forward-branch, compute-out-edges)
(propagate-analysis, eliminate-common-subexpressions-in-fun): Plumb
consts through the algorithm.
(fold-branch): Fold an eq-constant? using the flow-determined constant
info. Finally allows compile-bytecode to fold to switch statements!
* module/language/cps/optimize.scm (optimize-first-order-cps): Move
branch chain optimization before the final CSE/DCE pass.

Fix from
7cf4c01039:
Apply fix from Per Bothner.
In Per's words:
* testing.scm (%test-end): Reset test-runner-current if done.
This fixes bug "Loading test source file multiple time without having
report incrementing" reported to srfi-64 mailing list.
* srfi-64-test.scm: Update due to recent srfi-64 implementation change.
* module/language/cps/compile-bytecode.scm (compile-function): Expect
eq-constant? instead of eq-null?, etc.
* module/language/cps/effects-analysis.scm: Likewise.
* module/language/cps/reify-primitives.scm (reify-primitives): For
eq-constant?, reify a $const unless the constant is an immediate whose
encoding fits in 16 bits.
* module/language/cps/type-fold.scm (materialize-constant): Helper to
make a constant from a type, min, and max.
(fold-eq-constant?): New helper.
(eq-constant?): New folder.
(undefined?): Define specifically.
(define-nullish-predicate-folder): Renamd from
define-special-immediate-predicate-folder. Use only for null?, false,
and nil?.
(*branch-reducers*): New mechanism. Reduce eq? to eq-constant? if
possible.
(local-type-fold): Refactor to use materialize-constant, and to allow
reducing branches.
* module/language/cps/types.scm (constant-type): Return three values
instead of a type entry.
(constant-type-entry): New function that returns a type entry. Adapt
callers.
(infer-constant-comparison): New helper.
(eq-constant?): New inferrer.
(undefined?): New inferrer.
* module/language/tree-il/compile-bytecode.scm (eq-constant?): Fix
truncate-bits signed arg.
(define-immediate-type-predicate): Adapt to visit-immediate-tags
change.
* module/language/tree-il/compile-cps.scm (convert): Convert eq? to
constant to eq-constant?. Advantaged is that it gets fixnums and
chars in addition to special immediates.
* module/language/tree-il/cps-primitives.scm (define-immediate-type-predicate):
Adapt to allow #f as pred.
* module/system/base/types/internal.scm (immediate-tags): Use #f as pred
for false, nil, etc.
(immediate-bits->scm): Adapt.
* module/system/vm/assembler.scm (emit-eq-null?, emit-eq-nil?)
(emit-eq-false?, emit-eq-true?, emit-unspecified?, emit-eof-object?):
Remove specialized emitters.
* module/system/vm/assembler.scm (define-immediate-tag=?-macro-assembler):
Allow for pred to be #f.
* module/system/vm/disassembler.scm (define-immediate-tag-annotation):
Adapt to pred being #f.
* module/language/tree-il/compile-bytecode.scm (eq?): Define
eq-immediate? as immediate emitter.
(canonicalize): Don't fuss so much about eq?; only if commutation is
needed. (Perhaps a more generic commutation pass is needed.)
(compile-closure): Add support for emit/immediate for branches.
* module/system/base/types/internal.scm (scm->immediate-bits):
(immediate-bits->scm, sign-extend, truncate-bits): New public
routines.
* module/system/vm/assembler.scm (immediate-bits): Reimplement in terms
of scm->immediate-bits and similar.
(X8_S8_I16, X8_S8_ZI16): Rework operand encodings.
(load-constant): Use truncate-bits to determine which cases apply.
* doc/ref/vm.texi (Instruction Set, Constant Instructions): Document new
instruction.

word kind with zi16 operand.
* libguile/jit.c (compile_make_immediate, compile_make_immediate_slow):
New compilers.
(COMPILE_X8_S8_ZI16): New operand kind.
* libguile/vm-engine.c (make-immediate): New instruction.

operands.
