The C standard does not allow size-zero arrays, so redo struct
Lisp_Subr to not use size-zero arrays when native compilation is
not being used. Formerly, the code was using size-zero arrays (a
GNU C extension) to avoid using memory unnecessarily when
HAVE_NATIVE_COMP is not defined. Replace this hack with the
more-traditional hack of putting the relevant members inside
‘#ifdef HAVE_NATIVE_COMP’.
* src/alloc.c (cleanup_vector, mark_object):
* src/comp.c (make_subr):
* src/data.c (Fsubr_native_lambda_list, Fsubr_native_comp_unit):
* src/eval.c (init_eval_once, funcall_lambda):
* src/lisp.h (SUBR_NATIVE_COMPILEDP, SUBR_NATIVE_COMPILED_DYNP)
(SUBR_TYPE):
* src/lread.c (Fload):
Conditionally compile with ‘#ifdef HAVE_NATIVE_COMP’ instead of
with ‘if (NATIVE_COMP_FLAG)’. Redo members like native_comp_u[0]
to be plain native_comp_u. Put all uses of these members inside
‘#ifdef HAVE_NATIVE_COMP’.
* src/lisp.h (struct Lisp_Subr): Members native_comp_u,
native_c_name, lambda_list, type are now all ifdeffed out if
HAVE_NATIVE_COMP is not defined, instead of being size-zero
arrays. All uses changed.
* src/pdumper.c (dump_subr, dump_cold_native_subr)
(dump_do_dump_relocation):
* src/comp.h (NATIVE_COMP_FLAG): Remove; no longer needed.
Without this patch, the build fails on Solaris 10 with the diagnostic
“Undefined symbol acl_trivial first referenced in file
../lib/libgnu.a(file-has-acl.o)”.
* lib-src/Makefile.in (LIB_HAS_ACL): New macro.
(emacsclient${EXEEXT}): Link with $(LIB_HAS_ACL).
* src/fileio.c (Fcopy_file): Work around a compiler bug in IBM XL
C for AIX, V12.1 (5765-J02, 5725-C72). Without this patch, the
compiler incorrectly complains “Initialization between types "int"
and "struct timespec" is not allowed” and “Initialization between
types "long" and "struct timespec" is not allowed”.
* test/lisp/tab-bar-tests.el: New file.
(tab-bar-tests-close-other-tabs-with-arg): Test for regression
that closed the selected tab after selecting it.
* lisp/repeat.el (repeat-check-key): Use for repeat-check-key the same logic
as is used for repeat-exit-timeout in repeat-post-hook (bug#51390).
(repeat-post-hook): Check for repeat-exit-timeout symbol property.
* lisp/help.el (help--analyze-key): Use posn-set-point instead of
mouse-set-point that runs the hook mouse-leave-buffer-hook via
mouse-minibuffer-check. Using posn-set-point also unnecessitates
extra conditions added in bug#51421.
* lisp/isearch.el (isearch-describe-key, isearch-describe-mode):
Add precautions to not call isearch-update when the executed
command exited isearch-mode (bug#51173).
This fixes bug #52157.
* lisp/progmodes/cc-engine.el (c-forward-decl-or-cast-1): If such a construct
is parsed, set the flag at-type-decl which is part of the function's return
value.
* lisp/repeat.el (repeat-check-key): New defcustom (bug#51390).
(repeat--command-property): New internal function.
(repeat-check-key): New function.
(repeat-post-hook): Use repeat--command-property and repeat-check-key.
* test/lisp/repeat-tests.el (repeat-tests-check-key): New test.
