* src/comp.c (add_driver_options): Throw an error if
`comp-native-driver-options' is set globally but
'gcc_jit_context_add_driver_option' is not available, ignore for
the file-local case.
* src/w32.c (shutdown_handler): Clear the message stack when being
shut down in noninteractive mode, to avoid aborting in
shut_down_emacs when a native-compilation subprocess is killed
because the parent Emacs exits.
* lisp/emacs-lisp/comp.el: Use 'w32-get-nproc' instead of the
environment variable NUMBER_OF_PROCESSORS.
* src/w32proc.c (Fw32_get_nproc): New primitive.
* src/w32.c (w32_get_nproc): New function.
(sample_system_load): Call w32_get_nproc to initialize the number
of processors on this system.
* src/w32.h (w32_get_nproc): Add prototype.
* src/comp.c [WINDOWSNT]: Import gcc_jit_context_set_str_option.
(init_gccjit_functions): Load gcc_jit_context_set_str_option.
(gcc_jit_context_set_str_option) [WINDOWSNT]: New macro.
(Fcomp__compile_ctxt_to_file) [WINDOWSNT]: Pass the actual name of
the libgccjit DLL to the library, to be used as PROGNAME.
* src/comp.c (comp_hash_source_file)
(Fcomp__compile_ctxt_to_file, Fnative_elisp_load): Encode file
names before passing them to library APIs.
(Fcomp__compile_ctxt_to_file): use emacs_fopen instead of fopen.
(declare_lex_function): Avoid keeping a 'char *' pointer around
while calling Lisp, which could trigger GC, which could relocate
string data.
Account for subr arity in `comp-abi-hash' computation as that's part
of the ABI exposed to .eln files.
* src/comp.c (Fcomp__subr_signature): New support function.
(hash_native_abi): Make use of.
(syms_of_comp): Register 'Scomp__subr_signature'.
* src/comp.c (helper_link_table): Don't include SETJMP except on Windows.
(emit_setjmp): Don't use function pointers except on Windows.
(declare_runtime_imported_funcs): Don't import SETJMP at runtime.
(ABI_VERSION): Bump.
* test/src/comp-tests.el (46824-1): New test.
* test/src/comp-test-funcs.el (comp-test-46824-1-f): New function.
* src/comp.c (emit_rvalue_from_emacs_uint)
(emit_rvalue_from_lisp_word_tag): Fix comparison of unsigned
values.
(gcc_jit_context_new_rvalue_from_ptr): Define only if
LISP_WORDS_ARE_POINTERS, to avoid compilation warning.
(init_gccjit_functions): Load gcc_jit_context_new_rvalue_from_ptr
only if LISP_WORDS_ARE_POINTERS.
* src/emacs.c (set_invocation_vars) [WINDOWSNT]: If argv0 is not
an absolute file name, obtain the absolute file name of the Emacs
executable from 'w32_my_exename'.
Further testing seems to confirm my suspicion that the increase in the
specpdl comes from the recent change to `pcase--if`.
* lisp/international/mule-cmds.el (update-leim-list-file): Revert workaround.
* src/marker.c (unchain_marker): Clean up obsolete comment
(bug#46836).
Commit cf3164523b (* src/alloc.c: Avoid O(N²) complexity when
unchaining markers (bug#24548)., 2018-03-23) removed the call from GC
into unchain_marker, so there is no need to warn about it.
* src/fns.c (Fyes_or_no_p): Don't use braces around one-line
block.
(syms_of_fns) <use-short-answers>: Improve the wording of the doc
string.
* etc/NEWS: Improve wording of the entry about 'use-short-answers'.
* src/nsterm.m ([EmacsView windowDidChangeBackingProperties:]):
([EmacsView viewWillDraw]): Only run this code when actually drawing
to an offscreen bitmap.
In some situations involving Internet access not being fully
functional, gnutls_handshake returns a fatal error, which we were
ignoring, causing us to call gnutls_handshake again. Now we check for
the error and return it to the caller.
* src/gnutls.c (gnutls_try_handshake): Return immediately if
gnutls_handshake returns a fatal error (Bug#46709).
* src/xdisp.c (resize_mini_window): Resize the mini-window
when multi-line text is displayed under truncate-lines
non-nil in the minibuffer. (Bug#46718)
Simplify closure creation by calling a single function at run time
instead of putting it together from small pieces. This is faster
(by about a factor 2), takes less space on disk and in memory, and
makes internal functions somewhat readable in disassembly listings again.
This is done by creating a prototype function at compile-time whose
closure variables are placeholder values V0, V1... which can be seen
in the disassembly. The prototype is then cloned at run time using
the new make-closure function that replaces the placeholders with
the actual closure variables.
* lisp/emacs-lisp/bytecomp.el (byte-compile-make-closure):
Generate call to make-closure from a prototype function.
* src/alloc.c (Fmake_closure): New function.
(syms_of_alloc): Defsubr it.
* src/data.c (syms_of_data): Defsym byte-code-function-p.
* lisp/emacs-lisp/byte-run.el (byte-run--set-modes): Change from
being a predicate to storing the modes. This allows using the
modes for positive command discovery, too.
* src/data.c (Fcommand_modes): Look at the `command-modes' symbol
property, too.
* src/comp.c (emit_rvalue_from_unsigned_long_long): Remove
function.
(emit_rvalue_from_emacs_uint, emit_rvalue_from_lisp_word_tag)
(emit_rvalue_from_lisp_word): Make use of
'emit_rvalue_from_long_long'.
* src/comp.c (emit_rvalue_from_emacs_uint)
(emit_rvalue_from_lisp_word_tag): Pacify GCC warning.
(emit_rvalue_from_unsigned_long_long): Define it only when
necessary.
