* 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.
* libguile/jit.c (scm_jit_compute_mcode): If a caller wants mcode for a
loop but the function already has mcode, instead of punting, just
compile again.
