Fixes <https://bugs.gnu.org/22925> and other bugs.
* module/ice-9/match.upstream.scm: Apply selected fixes from the
upstream match.scm in Chibi-Scheme.
* test-suite/tests/match.test.upstream: Add more tests from upstream.
* module/ice-9/match.upstream.scm: Change several occurrences
of 'ellipse' and 'ellipses' to 'ellipsis', to more closely match
match.scm from Chibi-Scheme.
Fixes <https://bugs.gnu.org/26163>.
Reported by Zefram <zefram@fysh.org>.
* module/srfi/srfi-19.scm (time-compare-check): New procedure.
(time=?): Use 'time-compare-check' to check the arguments and raise an
error in case of mismatched types. Previously, mismatched types would
cause time=? to return #f.
(time>?, time<?, time>=?, time<=?, time-difference!): Use
'time-compare-check' to check the arguments.
Fixes <https://bugs.gnu.org/21906>.
Mitigates <https://bugs.gnu.org/21903> and <https://bugs.gnu.org/21904>.
Reported by: Zefram <zefram@fysh.org>.
* module/srfi/srfi-19.scm (encode-julian-day-number)
(decode-julian-day-number, date-week-number): Use 'floor-quotient'
instead of 'quotient', and 'floor' instead of 'truncate', where
appropriate.
(time-utc->date): Ensure that the 'nanoseconds' field of the returned
date is non-negative.
(leap-year): Handle negative years properly, and reformulate the
computation.
(week-day): Handle negative years properly. Use 'floor-quotient'
instead of 'quotient' where appropriate.
(directives): In the handler for '~Y' format escapes, improve the
handling of years outside of the range 0-9999.
(read-directives): Add a FIXME comment to fix the '~Y' reader to handle
years outside of the range 0-9999.
* test-suite/tests/srfi-19.test: Import (srfi srfi-1). Use Guile's
modern keyword notation in the 'define-module' form. Add more tests.
Fixes <https://bugs.gnu.org/21911>.
Fixes <https://bugs.gnu.org/22034>.
Fixes <https://bugs.gnu.org/21902>.
Partially fixes <https://bugs.gnu.org/21904>.
Reported by Zefram <zefram@fysh.org>.
* doc/ref/srfi-modules.texi (SRFI-19 Introduction): Fix the definitions
of Julian Day and Modified Julian Day. Give the correct full names of
UTC and TAI.
* module/srfi/srfi-19.scm: Import (srfi srfi-1). Use modern Guile
keyword syntax in the 'define-module' form.
(leap-second-neg-delta): New procedure, derived from a similar procedure
in the latest upstream SRFI-19 reference implementation.
(priv:time-tai->time-utc!, time-tai->julian-day)
(time-monotonic->julian-day): Use 'leap-second-neg-delta'.
(local-tz-offset): Fix comment.
(leap-second?): Remove.
(tai-before-leap-second?): New procedure, derived from upstream SRFI-19.
(time-utc->date): Use 'define*' to handle the optional argument. Remove
the leap second handling, following upstream SRFI-19.
(time-tai->date): Rewrite in terms of 'time-utc->date'. Add special
leap second handling, following upstream SRFI-19.
(time-monotonic->date): Rewrite in terms of 'time-tai->date'.
(date->time-tai, date->time-monotonic): Add special leap second
handling, following upstream SRFI-19.
(directives): In the entry for the "~Y" escape in 'date->string', pad
the year field to 4 characters, following upstream SRFI-19.
* test-suite/tests/srfi-19.test: Add tests.
* module/language/cps/simplify.scm (eta-reduce): Fix renaming of labels
referenced by prompts. Thanks a million to Stefan Israelsson Tampe
for the report and the fix! Fixes#33652.
* libguile/macros.c (scm_i_make_primitive_macro): Give primitive macros
a primitive-macro macro-type.
* module/ice-9/psyntax.scm (put-global-definition-hook)
(get-global-definition-hook): Inline into uses.
(make-binding): Change format of lexically defined or rebound syntax
parameters to just be the transformer, not a list of the transformer.
(resolve-identifier, expand-install-global, expand-body)
(syntax-parameterize): Adapt to use the variable object (box) holding
the top-level syntax parameter as the "key" for lookups into the
lexical environment, instead of a fresh object associated with the
syntax transformer.
* module/ice-9/psyntax-pp.scm: Regenerate.
Fixes#27476, a horrible race when one thread is expanding a
syntax-parameterize form including uses, and another thread is expanding
the corresponding define-syntax-parameter. See
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=27476#102.
* module/system/vm/linker.scm (<linker-object>): Add name field. This
allows the linker to find sections by name, notably before having
found the .shstrtab section. As there can be multiple sections with
type SHT_STRTAB, this fixes a bug whereby we could use a section
name (a strtab index) into an unrelated strtab. In the past this
worked because with ASCII identifiers there won't be an exception,
although it is possible to accidentally mistake a shared string tail;
but with UTF-8 identifiers, it's possible for a string table index to
point in the middle of a codepoint, which is likely not valid UTF-8
and would raise a bug. Keeping an additional section name field fixes
this bug. Adapt all callers to pass a name argument to
make-linker-object.
(find-shstrndx): Update to look at the name field.
* module/system/vm/assembler.scm (make-object): Pass name to
make-linker-object.
Thanks to Daniel Llorens for the test case.
* libguile/loader.h (SCM_OBJCODE_MINIMUM_MINOR_VERSION):
(SCM_OBJCODE_MINOR_VERSION): Bump version.
* module/system/vm/assembler.scm (*bytecode-minor-version*): Bump.
* libguile/vm-engine.c: Rearrange opcodes to be contiguous and in a
somewhat sensible order.

SCM_VM_ABORT_CONTINUATION_HOOK.
* libguile/vm-engine.c (ABORT_HOOK):
* libguile/vm.c (invoke_abort_hook): Adapt to SCM_VM_ABORT_HOOK name
change.
(reset_vm_hook_enabled): New helper.
(VM_ADD_HOOK, VM_REMOVE_HOOK): New helper macros, replacing
VM_DEFINE_HOOK.
(scm_vm_add_abort_hook_x, scm_vm_remove_abort_hook_x)
(scm_vm_add_apply_hook_x, scm_vm_remove_apply_hook_x)
(scm_vm_add_return_hook_x, scm_vm_remove_return_hook_x)
(scm_vm_add_next_hook_x, scm_vm_remove_next_hook_x): New functions,
replacing direct access to the hooks. Allows us to know in a more
fine-grained way when to enable hooks.
(scm_set_vm_trace_level_x): Use reset_vm_hook_enabled to update the
individual hook_enabled flags.
* module/statprof.scm:
* module/system/vm/coverage.scm:
* module/system/vm/traps.scm:
* module/system/vm/vm.scm: Adapt VM hook users to the new API.
* libguile/intrinsics.h: Add "intrinsic" for handle-interrupts code.
Unlike the other intrinsics, this one isn't a function.
* libguile/programs.c (try_parse_arity): Add cases for instructions used
in VM builtins.
(scm_primitive_call_ip): Return #f if call-ip not found.
* libguile/vm-engine.c (handle-interrupts): Get code from intrinsics.
* libguile/vm.c
* libguile/vm.c (instrumented_code, define_vm_builtins): Add
instrumentation to the builtins, so that they can be JIT-compiled.
(INIT_BUILTIN): Remove min-arity setting; the fallback min-arity
interpreter should figure it out.
(scm_bootstrap_vm): Call the new define_vm_builtins function.
* libguile/gsubr.c (primitive_call_ip): Return 0 if call IP not found.
(primitive_subr_idx): Interpret call ip == 0 as not-a-subr.

and also handle the stack manipulation.
* libguile/vm-engine.c (expand-apply-argument): Update for intrinsic
change.
(call-scm-sz-u32): Rename from call-scm-u64-u64, as it matches its
uses and will compile better on 32-bit systems.
* module/system/vm/assembler.scm (define-scm-sz-u32-intrinsic):
(string-set!): Update for new instrinsic call inst.
* libguile/jit.c (compile_call_scm_sz_u32): Adapt.
Fixes <https://bugs.gnu.org/32329>.
Reported and diagnosed by Göran Weinholt <goran@weinholt.se>.
* module/rnrs/io/simple.scm (call-with-input-file)
(call-with-output-file): Use 'open-{input,output}-file' to open the port
in textual mode. Previously 'open-file-{input,output}-port' was used,
which opened the port in binary mode.
* module/language/tree-il/analyze.scm (shadowed-toplevel-analysis): New
variable.
* module/language/tree-il/compile-cps.scm (%warning-passes): Add it.
* module/system/base/message.scm (%warning-types): Add it.

'macro-use-before-definition'.
Commit eb90831ce8 added it to the wrong
makefile.
* module/Makefile.am (SOURCES): Add srfi/srfi-71.scm.
* module/srfi/Makefile.am: Remove. It's a leftover from the 2009 build
system rework in commit 3bb299b3f0.
* module/ice-9/command-line.scm (version-etc): Change #:copyright-year
to 2018.
* doc/ref/guile.texi: Add 2017 and 2018 to the copyright years.
* configure.ac (GUILE_CONFIGURE_COPYRIGHT): Add 2018.
Fixes <https://bugs.gnu.org/30602>.
Previously, when compiling files in parallel like Guix does, threads
would be concurrently inserting, rehashing, and reading the submodule
hash table of module (). Thus, some threads would sometimes see an
inconsistent state, leading to errors such as:
Module named (system repl debug) does not exist
* module/ice-9/boot-9.scm (call-with-module-autoload-lock): Move higher
in the file.
(module-name): Use it around call to 'nested-define-module!'.
(resolve-module): Wrap the whole thing in 'call-with-module-autoload-lock'.
* module/system/vm/linker.scm (find-shstrndx): Check whether NAME is
lower than the length of BV; remove 'false-if-exception' around
'string-table-ref' call.
* module/system/base/types.scm (read-c-string, inferior-port-type): New
procedures.
(inferior-port): Use 'inferior-port-type' to determine the port type.
(cell->object): Rename 'flags+type' to 'flags' in the '%tc7-port' case.
* test-suite/tests/types.test ("opaque objects"): Adjust port testse.
(test-inferior-ports): New macro.
("ports"): New test prefix.
Fixes <https://bugs.gnu.org/31878>.
* module/ice-9/boot-9.scm (call-with-module-autoload-lock): New procedure.
(try-module-autoload): Wrap body in 'call-with-module-autoload-lock'.
* module/ice-9/threads.scm: Set (@ (guile) call-with-module-autoload-lock).
