The current implementation of srfi-11s let-values allows later clauses
to access and modify variables bound in earlier clauses when the clause
is not a proper list.
* module/srfi/srfi-11.scm (let-values): Fix switched variable names.
* test-suite/tests/srfi-11.test (let-values): Add test checking that the
variable cannot be changed in later clauses.
Previously (fluid-ref (make-thread-local-fluid #t)) would return #f via
scm_fluid_ref because the internal scm_hashq_ref would return #f when
the fluid had not been set, and that was interpreted as an actual value
for the fluid.
Instead, just pass the fluid default as the default for the hash table
lookups so that we don't need a second step to determine if the fluid
was set.
Thanks to Andrew Gierth for tracking down the problem.
* module/language/tree-il/peval.scm (peval): Fix arity check for type
confusion (empty value of "rest" in this context was (), not #f). The
effect was that we'd silently allow extra arguments to inlined calls.
Thanks to Christopher Lam for the report! Fixes#38617.
* test-suite/tests/peval.test ("partial evaluation"): Add a test.
* module/Makefile.am (ice-9/boot-9.go, NOCOMP_SOURCES): Add
r7rs-libraries.
* module/ice-9/boot-9.scm ("ice-9/r7rs-libraries"): Include file.
* module/ice-9/psyntax.scm (call-with-include-port): New definition.
(include): Use call-with-include-port.
* module/ice-9/psyntax-pp.scm: Regenerate.
* module/ice-9/r7rs-libraries.scm: New file.
* module/scheme/base.scm (r7:include, r7:include-ci): Fix mistaken use
of core "include". Use include-ci from core.
(features): Remove features that are already part of core.
* NEWS: Update.
* module/language/cps/closure-conversion.scm (convert-one):
Strongly-connected components of letrec bindings that do not share a
closure may include member functions that have a single free variable,
or even no free variables as a result of free variable pruning.
Handle this case instead of erroring out. Thanks to Stefan Israelsson
Tampe for the report.
* module/ice-9/exceptions.scm (guard): Add guard definition that
re-propagates from original continuation, runs consequents in tail
position in guard continuation, and doesn't rewind the stack.
* module/srfi/srfi-34.scm:
* module/rnrs/exceptions.scm (guard): Re-export from (ice-9
exceptions).
* doc/ref/compiler.texi (Extending the Compiler):
* doc/ref/history.texi (A Timeline of Selected Guile Releases):
(Status): Update. Thanks to Mikael Djurfeldt for the bug report.
With this patch, these two lines
(vector-fill! vec fill)
(vector-fill! vec fill 0 end)
run at the same speed; before, the second one was much slower.
This patch also makes it an error to call vector-fill! with a non-vector
array. The previous implementation did not work correctly in this case.
* libguile/vectors.c (SCM_VALIDATE_MUTABLE_VECTOR): Better error message.
(vector-fill!): Handle optional arguments start, end. Do not attempt
to handle non-vector arrays. Rename the C binding to
scm_vector_fill_partial_x.
(scm_vector_fill_x): Reuse scm_vector_fill_partial_x.
* module/srfi/srfi-43.scm (vector-fill!): Remove & re-export the core
version instead.
* libguile/vm.c (scm_i_vm_emergency_abort, abort_to_prompt): Unwinding
the dynwind stack can run dynwind leave thunks, which may expand the
stack, which may invalidate previously calculated SP / FP values.
(Re)calculate SP/FP after unwinding, to avoid writing to unmapped
memory. Fixes compile errors seen on Ubuntu and some other ports.
Previously we'd get warnings like:
t.scm:11:0: warning: shadows previous definition of `unused-constructor-51900bdce47d50c' at /tmp/t.scm:6:0
whenever 'define-condition-type' appeared more than once in a source
file.
* module/srfi/srfi-35.scm (define-condition-type): Rewrite as
'syntax-case' and generate UNUSED-CONSTRUCTOR as a function of TYPE.
* libguile/fports.c (scm_i_fdes_is_valid): New internal helper.
(scm_i_fdes_to_port): Use new helper.
* libguile/fports.h: Declare new helper.
* libguile/init.c (scm_standard_stream_to_port): Refactor to use
scm_i_fdes_is_valid.
* doc/ref/guile-invoke.texi (Environment Variables): Remove
GUILE_STACK_SIZE which is no longer needed, and document some JIT
debugging environment variables.
* doc/ref/vm.texi (Why a VM?, Just-In-Time Native Code): Update and link
to environment variables documentation.
* libguile/jit.c (compile_alloc_frame, compile_alloc_frame_slow): Move
slow path out of line.
(emit_alloc_frame_for_sp_fast, emit_alloc_frame_for_sp_slow): New
helpers.
(emit_alloc_frame): Refactor to use the new helpers.
(compile_push, compile_push_slow): Use the new helpers.
(compile_assert_nargs_ee_locals, compile_assert_nargs_ee_locals_slow):
Split off a slow path.
* libguile/jit.c (struct pending_reloc): Rename target_vcode_offset
field to target_label_offset.
(inline_label_offset, slow_label_offset): New helpers.
(emit_direct_tail_call): Use inline_label_offset helper.
(add_pending_reloc): Factor out of add_inter_instruction_patch.
(add_inter_instruction_patch): Use inline_label_offset helper.
(add_slow_path_patch): New helper.
(continue_after_slow_path): New helper.
Add slow path compilers for all instructions.
(compile_slow_path): New helper.
(compile): Compile slow paths after main code.
(compute_mcode): Allocate twice as many labels.
* libguile/jit.c (emit_alloc_frame_for_sp):
* libguile/vm-engine.c (ALLOC_FRAME, RESET_FRAME):
* libguile/vm.c (vm_increase_sp, scm_i_vm_prepare_stack):
(return_unused_stack_to_os, vm_expand_stack, alloc_frame):
(scm_call_with_stack_overflow_handler):
* libguile/vm.h (struct scm_vm): Remove sp_min_since_gc handling. It
was a very minor optimization when it was centralized in vm.c, but now
with JIT it's causing too much duplicate code generation.
Fixes <https://bugs.gnu.org/37757>.
Reported by Jesse Gibbons <jgibbons2357@gmail.com>.
* libguile/finalizers.c (finalization_thread_proc): Do not enter the
"switch (data.byte)" condition when data.n <= 0.
