Keep track of the end of specpdl explicitly since that is what we are
comparing against on critical code paths.
* src/eval.c (init_eval_once_for_pdumper, signal_or_quit)
(grow_specpdl_allocation):
* src/fileio.c (Fdo_auto_save):
* src/lisp.h (grow_specpdl):
* src/thread.c (run_thread, Fmake_thread):
* src/thread.h (struct thread_state):
Replace specpdl_size with specpdl_end, according to the equation
specpdl_end = specpdl + specpdl_size.
|
|
It's critical in several function call paths.
* src/eval.c (grow_specpdl_allocation): Make non-static.
(grow_specpdl, record_in_backtrace): Move from here...
* src/lisp.h (grow_specpdl, record_in_backtrace): ... to here,
and declare inline.
|
|
* src/lisp.h (enum specbind_tag): New elem SPECPDL_NOP.
* src/eval.c (specpdl_unrewind): Zap entries that can't be applied any more,
and simplify.
(default_toplevel_binding, lexbound_p, Fbacktrace__locals): Simplify.
(do_one_unbind, mark_specpdl): Handle SPECPDL_NOP.
|
|
* src/eval.c (funcall_lambda): Rewrite obsolete comment.
* src/bytecode.c (exec_byte_code): Remove lying comment and
unneeded #define.
* lisp/emacs-lisp/byte-opt.el: Remove car. Keep pig.
(byte-compile-log-lap-1): Remove obsolete and irrelevant comment.
|
|
|
|
* src/eval.c (specpdl_unrewind): Avoid a compilation warning.
|

Make the context switch code handle buffer-local variables more
correctly by reusing the code originally written for `backtrace-eval`.
This has the side benefit of making the `saved_value` field unused.
* src/lisp.h (enum specbind_tag): Remove `saved_value` field.
(rebind_for_thread_switch, unbind_for_thread_switch): Delete decls.
(specpdl_unrewind): Declare function.
* src/eval.c (specpdl_saved_value): Delete function.
(specbind): Delete the code related to `saved_value`, and consolidate
common code between the different branches.
(rebind_for_thread_switch, -unbind_for_thread_switch): Move to `thread.c`.
(specpdl_unrewind): New function, extracted from `backtrace_eval_unrewind`.
Use `SET_INTERNAL_THREAD_SWITCH`. Skip the buffer & excursion unwinds
depending on new arg `vars_only`.
(backtrace_eval_unrewind): Use it.
(mark_specpdl): Don't mark `saved_value`.
* src/thread.c (rebind_for_thread_switch, unbind_for_thread_switch):
Move from `eval.c` and rewrite using `specpdl_unrewind`.
* test/src/thread-tests.el (threads-test-bug48990): New test.
* test/Makefile.in (test_template): Add a + as suggested by make:
"warning: jobserver unavailable: using -j1. Add '+' to parent make rule".

The specpdl_ref type is just an alias for ptrdiff_t; the compiled code
remains the same. All operations on specpdl_ref (arithmetic,
comparison etc) now go through inline functions.
The bulk of the change is almost completely mechanical. It is done to
prepare for a type-safe representation and subsequent performance
improvement.

This is also used in batch mode in general.
* lisp/debug-early.el (debug-early-backtrace, debug-early): New functions.
* lisp/loadup.el (top level): Load debug-early.el as first file.
* src/eval.c (signal_or_quit): Remove the condition in the batch mode section
of not being in dumping or bootstrap, since it is no longer needed. Test that
'debug-early's symbol-function is bound. Ensure there is enough working space
in specpdl and eval_depth.
(syms_of_eval): New DEFSYM for Qdebug_early. Initialise Vdebugger to
Qdebug_early rather than Qnil.
|
|
|
|
* src/eval.c (funcall_subr): Test most likely cases first (conforming
calls to finite-arity or n-adic SUBRs), and the error cases last,
instead of doing it the other way around. Simplify.

Vdebugger) to Qdebug in the section for errors in batch jobs.
(syms_of_eval): New DEFSYM for Qdebugger.

Rework the code we have in Fdefalias that tries to keep track
of definitions so as to be able to undo them later.
We used to store in `load-history` when an autoload is redefined as
a non-autoload and in the `autoload` symbol property we used to store
the autoload data that used to be used before it got overriden.
Instead, store the history of the function definition of
a symbol in its `function-history` symbol property.
To make this list cheap in the default case, the latest value is not stored
in the list (since it's in the `symbol-function`) and neither is the first
file. So if there's only been a single definition (the most common case),
the list is empty and the property is just not present at all.
The patch also gets rid of the `autoload` vs `defun` distinction in
`load-history` which seems unnecessary (a significant part of the
motivation for this patch was to get rid of the special handling of
autoloads in this part of the code).
* src/data.c (add_to_function_history): New function.
(defalias): Use it. Don't add the `t` entries for autoloads and always
use `defun` regardless of the kind of definition.
Change `Vautoload_queue` to only hold the function
symbols since the rest is now available from `function-history`.
* src/eval.c (un_autoload): Adjust accordingly.
* src/lread.c (load-history): Udate docstring.
* lisp/loadhist.el (loadhist-unload-filename): New var.
(unload-feature): Bind it.
(loadhist-unload-element): Document its availability.
(loadhist--restore-autoload): Delete var.
(loadhist--unload-function): Delete function.
(loadhist-unload-element): Delete the `t` and `autoload` methods.
Rewrite the `defun` method using `function-history`.
* lisp/help-fns.el: Require `seq`.
(help-fns--autoloaded-p): Rewrite.
(help-fns-function-description-header): Adjust call accordingly.
* doc/lispref/loading.texi (Where Defined): Remove `autoload` and `t`
entries from `load-history` since we don't generate them any more.
Document the `function-history` which replaces the `autoload` property.
(Unloading): Adjust symbol property name accordingly.
* test/lisp/loadhist-resources/loadhist--bar.el:
* test/lisp/loadhist-resources/loadhist--foo.el: New files.
* test/lisp/loadhist-tests.el (loadhist-tests-unload-feature-nested)
(loadhist-tests-unload-feature-notnested): New tests.
|
|
* src/data.c (defalias): New function, extracted from `Fdefalias`.
(Fdefalias): Use it.
(Ffset): Don't handle `Vautoload_queue` here, handle it in
`defalias` instead.
* src/comp.c (comp--register-subr): Use `defalias` instead of
duplicating its code.
* src/eval.c (load_with_autoload_queue): New function, extracted from
`Fautoload_do_load`.
(Fautoload_do_load): Use it.
(un_autoload): Mark it as static.
* src/fns.c (Frequire): Use it as well.
* src/lisp.h (defalias, load_with_autoload_queue): New declarations.
(un_autoload): Remove declaration.
|
|
Since `maybe_quit` is called on many critical paths, inline a slightly
cheaper condition (that ignores Vinhibit_quit).
* src/eval.c (maybe_quit): Rename to `probably_quit`.
* src/lisp.h (maybe_quit): New simplified inline function.
|
|
The common case is just to increment `specpdl_ptr`; do that in-line,
but move the uncommon reallocation to a separate subroutine.
* src/eval.c (grow_specpdl): Now inline, most code moved...
(grow_specpdl_allocation): ...here.
|
|
* src/eval.c (funcall_general, Ffuncall): Delegate the actual work in
Ffuncall to funcall_general which does exactly this.
This slows down some less used function call paths by a small amount
but the code duplication was just silly.
|
|
Since we pass no arguments to a non-lexbind bytecode function, we can
specify its arity as 0 instead of nil and save a test and branch.
* src/bytecode.c (Fbyte_code, exec_byte_code):
* src/eval.c (fetch_and_exec_byte_code, funcall_lambda):
* src/lisp.h:
Change the args_template parameter type to ptrdiff_t, since it is now
always a small integer, in exec_byte_code and
fetch_and_exec_byte_code, all callers adjusted.
|
|
Inline parts of the code for function calls to speed up the common
case of calling lexbound byte-code. By eliminating intermediate
functions, this also reduces C stack usage a little.
* src/bytecode.c (exec_byte_code): Inline parts of Ffuncall,
funcall_lambda and fetch_and_exec_byte_code in the Bcall opcode
handler.
* src/eval.c (backtrace_debug_on_exit): Inline and move to lisp.h.
(do_debug_on_call): Make global so that it can be called from
bytecode.c.
(funcall_general): New function, essentially the meat of Ffuncall.
* src/lisp.h (backtrace_debug_on_exit): Moved here from eval.c.

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.

specified as the success continuation of the protected form, with
the specified variable bound to its result.

from success handler.
* doc/lispref/control.texi (Handling Errors): Update manual.
* etc/NEWS: Announce.
* test/lisp/emacs-lisp/bytecomp-tests.el (bytecomp-tests--test-cases)

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.

|
* doc/lispref/commands.texi (Using Interactive): Document the
extended `interactive' form.
* doc/lispref/loading.texi (Autoload): Document list-of-modes
form.
* lisp/emacs-lisp/autoload.el (make-autoload): Pick the list of
modes from `interactive' out of the functions.
* lisp/emacs-lisp/bytecomp.el (byte-compile-lambda): Allow for the
extended `interactive' form.
* src/callint.c (Finteractive): Document the extended form.
* src/data.c (Finteractive_form): Return the interactive form in
the old format (even when there's an extended `interactive') to
avoid having other parts of Emacs be aware of this.
(Fcommand_modes): New defun.
* src/emacs-module.c (GCALIGNED_STRUCT): Allow for modules to
return command modes.
* src/lisp.h: New function module_function_command_modes.

* lisp/minibuffer.el (exit-minibuffer): When in a minibuffer, throw an error
should the command loop nesting level be wrong.
* src/lisp.h (minibuffer_quit_level): declare as an extern.
(command_loop_level): Move definition from src/window.h
* src/window.h (command_loop_level): move definition to src/lisp.h.
* src/eval.c (minibuffer_quit_level): Move this variable to file level from
being a static inside internal_catch.
(internal_catch): Simplify the logic.
* src/minibuf.c (Vcommand_loop_level_list): New variable.
(move_minibuffer_onto_frame): Set the major mode of *Minibuf-0*.
(Fminibuffer_innermost_command_loop_p): New primitive.
(Fabort_minibuffers): Check the command loop level before throwing t to 'exit,
and set minibuffer_quit_level too.
(read_minibuf): New variable calling_window.
Before stacking up minibuffers on the current mini-window, check that the
mini-window is not the current one.
Do not call choose_minibuf_frame from read_minibuf's unwinding process.
Bind calling_frame and calling_window over the recursive edit.
Set the new minibuffer's major mode directly.
Remove the switching away from the minibuffer after the recursive edit.
(get_minibuffer): Record the command loop level in new variable
Vcommand_loop_level_list. No longer set the major mode of a returned
minibuffer.
(minibuf_c_loop_level): New function.
(read_minibuf_unwind): New variables calling_frame, calling_window are unbound
from the binding stack. Remove old variable `window', which could not be set
reliably to the expired mini-window.
The expired minibuffer is determined as the nth in the list, rather than the
contents of the current or previous mini-window.
Switch the current window away from the mini-window here (moved from
read_minibuf).

* src/data.c (Fmake_variable_buffer_local):
* src/eval.c (Fdefvar): Add cross-references to 'defvar-local'.
