* libguile/vm-engine.h (DEAD): New macro, nulls out a value.
* libguile/vm-i-system.c:
* libguile/vm-i-loader.c:
* libguile/vm-i-scheme.c: Use DEAD when variables become dead.
Later we can #ifdef this out, but I want to give the buildbots a try
with this patch to make sure it's correct.
* module/ice-9/psyntax.scm (syntax-type): Return an additional value
that contains the entire form in _all_ cases, including for definition
forms. Previously, the entire form was not returned for definition
forms.
(expand-expr): Add an additional argument that contains the entire
form in _all_ cases, including for definition forms. Use it to
include the entire form in error messages, notably for definitions in
expression context. Include the source location information, which
was previously missing from these errors when the rhs expression was
an atom. Improve the "definition in expression context" error message
to be more comprehensible for Scheme beginners.
(expand-top-sequence, expand, expand-body): Adjust as needed to handle
the additional return value from 'syntax-type' and the additional
argument to 'expand-expr'.
* module/ice-9/psyntax-pp.scm: Regenerate.
* NEWS: Update.
* module/language/tree-il/peval.scm (peval):
* module/language/tree-il/primitives.scm (dynamic-wind): When you make a
gensym that just has to be compared against other gensyms, it will be
unique if the prefix doesn't end in something that can be interpreted
as a number. There's no reason to make that character something
difficult like " ". So change to use a dash in that case.
* module/ice-9/psyntax-pp.scm: Regenerate. More readable now.
* libguile/macros.c (scm_init_macros): Add definition of new
syntax-session-id helper.
* module/ice-9/psyntax.scm: Capture a reference to syntax-session-id at
boot time. Uniquify marks and labels using the session id.
* module/ice-9/boot-9.scm: Shunt syntax-session-id off to (system
syntax) once we finished booting.
* module/ice-9/compile-psyntax.scm: Override syntax-session-id when
remaking psyntax to avoid spurious diffs.
* module/ice-9/psyntax-pp.scm: Regenerate.
This reverts commit ad432bc831.
Not all gensyms need to be universally-unique: most of them just need to
be unique within some portion of a Guile session. We'll take a
different tack on this problem in the next commit.
* module/ice-9/local-eval.scm: New module (ice-9 local-eval) which
exports `the-environment', `local-eval', and `local-compile'.
* libguile/debug.c (scm_local_eval): New C function that calls the
Scheme implementation of `local-eval' in (ice-9 local-eval).
* libguile/debug.h (scm_local_eval): Add prototype.
* doc/ref/api-evaluation.texi (Local Evaluation): Add documentation.
* test-suite/tests/eval.test (local evaluation): Add tests.
* test-suite/standalone/test-loose-ends.c (test_scm_local_eval):
Add test.
* module/Makefile.am: Add ice-9/local-eval.scm.
Based on a patch by Mark H Weaver <mhw@netris.org>.
* module/language/tree-il/analyze.scm
(format-analysis)[check-simple-format-args]: New procedure. Use it.
Add support for applications of <module-ref>.
* module/system/base/message.scm (%warning-types): Handle the `format
simple-format' warning.
* module/language/scheme/spec.scm (scheme)[make-default-environment]:
Use `simple-format' as the default `format'.
* test-suite/tests/tree-il.test ("warnings")["format"]: Explicitly use
(@ (ice-9 format) format) where needed.
("simple-format"): New test prefix.
* module/ice-9/boot-9.scm:
* module/ice-9/psyntax.scm (syntax-module, syntax-local-binding)
(syntax-locally-bound-identifiers): After boot, move these definitions
to a new (system syntax) module.
* module/ice-9/psyntax-pp.scm: Regenerate.
* doc/ref/api-macros.texi: Add some words about syntax-module and
friends being in (system syntax).
* test-suite/tests/gc.test ("gc"): Fix "lexical vars are collectable"
test. (Previously, the binding was getting inlined, so we weren't
testing what we meant to test. Besides that, the value was a
constant, not a closure, so it wasn't collectable in the first place!)
* module/language/tree-il/peval.scm (peval): Fold (values
'singly-valued-expression) to 'singly-valued-expression in contexts
that expect multiple values, in addition to those that expect single
values.
* module/language/tree-il/compile-glil.scm (flatten-lambda-case): Fix
miscompilation of `values' in a push context with RA.
* test-suite/tests/tree-il.test: Add low-level test for this
miscompilation.
Fixes part of <http://bugs.gnu.org/10520>.
Reported by Bruno Haible <bruno@clisp.org>.
* libguile/vm-i-system.c (COMPILER_BARRIER): New macro.
(halt, return, return_values): Insert compiler barrier after each
assignment to `fp'.
This is a followup to 690a0112e5 ("Remove
the "has finalizer?" bit from pointer objects.")
* libguile/foreign.c (scm_set_pointer_finalizer_x): Leave the type cell
unchanged. Before, `equal?' would break on pointers on which
`set-pointer-finalizer!' had been called.
* test-suite/tests/foreign.test ("make-pointer")["equal? modulo
finalizer (set-pointer-finalizer!)"]: New test.
* module/ice-9/boot-9.scm (current-filename): Canonicalize the path, so
that the result is independent of the current directory, and so
that `dirname' can traverse up the file system, as in the
add-to-load-path example.
(add-to-path): Remove. The eval-when semantics make this macro too
tricky to explain -- people will start using it on other path-like
things, in lexical contours, whereas it only really makes sense with
load-like paths at the toplevel.
* doc/ref/api-evaluation.texi (Loading): Fix link to load-with-path
docs, and remove add-to-path docs.
* libguile/hashtab.c (scm_i_hashtable_print): Use `SCM_UNPACK', not
`SCM2PTR'.
* test-suite/tests/hash.test: Adjust tests that rely on the output of
the printer to just check for the suffix of the hash table's external
representation.
* libguile/frames.c: Add compile-time assertions on the layout of
`struct scm_vm_frame'.
(RELOC): Parenthesize and type VAL.
* libguile/frames.h (SCM_FRAME_STRUCT): Write in terms of
`SCM_FRAME_DATA_ADDRESS'.
(SCM_FRAME_DATA_ADDRESS): Parenthesize and type FP.
(SCM_FRAME_SET_DYNAMIC_LINK): Write in terms of
`SCM_FRAME_DYNAMIC_LINK'.
* libguile/vm.c (RELOC): Parenthesize and type SCM_P.
* test-suite/tests/asm-to-bytecode.test (native-cpu, native-word-size):
New procedures.
(test-target): When the target is the native CPU, use the native word
size instead of WORD-SIZE.
* libguile/symbols.c (scm_gensym): Make the gensym counter a 128-bit
thread-local, initialized to a random number upon the first call to
`gensym' within a given thread. This counter is rendered as a 22 byte
suffix of mostly base64 digits.
* libguile/threads.h (scm_i_thread): Add a thread-local gensym_counter.
* libguile/threads.c (guilify_self_1): Initialize gensym_counter to NULL.
* module/ice-9/boot-9.scm (syntax-local-binding): New binding.
* module/ice-9/psyntax.scm: Locally define a fluid that holds the
"transformer environment". with-transformer-environment calls a
procedure with the transformer environment, or raises an error if
called outside the extent of a transformer. Bind
transformer-environment in expand-macro.
(resolve-identifier): Backport this helper from master.
(syntax-local-binding): New procedure to return binding information of
a bound identifier (a lexical, macro, a pattern variable, a displaced
lexical, a global, or some other form).
* module/ice-9/psyntax-pp.scm: Regenerate.
* doc/ref/api-macros.texi (Syntax Transformer Helpers): Add docs for
syntax-local-binding, and syntax-source, and move some other
descriptions to this new section.
Based on a patch by Julian Graham <julian@member.fsf.org>
* libguile/values.c, libguile/values.h (scm_c_value_ref): New function.
* doc/ref/api-control.texi (Multiple Values): Add documentation.
* test-suite/standalone/test-scm-values.c: New test program.
* test-suite/standalone/Makefile.am: Add test-scm-values test.
* m4/gnulib-cache.m4: Use `dirfd'.
* libguile/filesys.c: Include Gnulib's <dirent.h> directly.
(dirfd): Remove. Suggested by Bruno Haible <bruno@clisp.org>.
* test-suite/tests/statprof.test ("statistical sample counts within
expected range"): Throw unresolved when one of A-DATA, B-DATA, and
C-DATA is #f, which means samples were not collected for this one.
