- Make propagate responsible for keeping SSA up to date.
- Run propagate-alloc as very last before final not to risk bothering
with mvar array allocation during previous tranformations.
- Fix SSA if TCO modify the CFG.
Merge duplicated objects during final. Precendece is:
1 d-default
2 d-impure
3 d-ephemeral
Now every object identify uniquely a relocation class. Because of
this there's no need to keep the reloc class into m-var.
When 'load-dangerous-libraries' was t, Emacs allowed loading .elc
files compiled by XEmacs. This patch removes the support for that use
case, and declares the variable obsolete.
* lisp/subr.el (load-dangerous-libraries): Declare obsolete.
* src/lread.c (Fload): Ignore its value, and thereby refuse to load
files byte compiled by XEmacs.
(syms_of_lread): Update doc string of 'bytecomp-version-regexp' to not
refer to it.
* doc/emacs/building.texi (Lisp Libraries): Remove its documentation.
* test/src/timefns-tests.el:
(format-time-string-padding-minimal-deletes-unneeded-zeros)
(format-time-string-padding-minimal-retains-needed-zeros)
(format-time-string-padding-spaces)
(format-time-string-padding-zeros-adds-on-insignificant-side):
Don't assume local time can represent 2000-02-15 00:00:00,
as there might be a DST jump over midnight.
Work even when timestamps are of (TICKS . HZ) form.
Simplify by avoiding need to call time-add.
Complete 3b4bd4be1d where I apparently failed to grep properly and
missed two more places where the dummy events were generated.
* src/nsterm.m ([EmacsView toolbarClicked:]):
* src/gtkutil.c (xg_tool_bar_callback): Don't emit dummy "prefix" events.
(eldoc--supported-p): Move after the vars it uses. Simplify.
(eldoc-print-current-symbol-info): Revert to previous code which
assumed a non-nil value of eldoc-documentation-function.
nnmail-cache-close did not work when ~/.nnmail-cache was a symlink
to some other directory. Reported by Michael Albinus (Bug#39793).
* lisp/gnus/nnbabyl.el (nnbabyl-create-mbox):
* lisp/gnus/nndiary.el (nndiary-generate-nov-file):
* lisp/gnus/nnfolder.el (nnfolder-possibly-change-group):
* lisp/gnus/nnmbox.el (nnmbox-create-mbox):
* lisp/gnus/nnml.el (nnml-generate-nov-file):
Pass ‘excl’ to nnmail-write-region when creating a file, for safety.
* lisp/gnus/nnmail.el (nnmail-write-region):
Add optional MUSTBENEW arg, to stay consistent with write-region.
Past ‘nofollow’ to set-file-modes only when MUSTBENEW is ‘excl’.
Omitting the extra brackets is a common mistake; see discussion at
https://lists.gnu.org/archive/html/emacs-devel/2020-02/msg00215.html
* src/regex-emacs.c (reg_errcode_t, re_error_msgid): Add REG_ECLASSBR.
(regex_compile): Check for the mistake.
* test/src/regex-emacs-tests.el (regexp-invalid): Test.
* etc/NEWS: Announce.
Add a new class of relocated objects that is in use just during load
process. This in order to avoid having to maintain them in the heap
and traverse them at every GC.
* lisp/emacs-lisp/package.el (package-install): Once we know the
package has successfully been installed using the `package-install`
command, instead of relying on the compile "Done" message, give a
message that tells the user that the package has been
installed. (Bug#21857)
Copyright-paperwork-exempt: yes

The 'substring' byte op was not emitted, apparently by mistake. Fix.
Suggested by Mark Oteiza <mvoteiza@udel.edu>.
* lisp/emacs-lisp/bytecomp.el (byte-defop-compiler): Add '1-3' clause.
(byte-compile-one-to-three-args): New.

Add 'byte-substring'.

(byte-opt-testsuite-arith-data): Test 'substring'.

This incorporates:
2020-02-24 getloadavg: don't use /usr/local when cross-compiling on AIX
2020-02-24 fcntl: add witness of gnulib override
* lib/fcntl.in.h, m4/getloadavg.m4: Copy from Gnulib.
* nt/gnulib-cfg.mk (OMIT_GNULIB_MODULE_fchmodat)
(OMIT_GNULIB_MODULE_lchmod): Set to true to omit building these
modules on MS-Windows.
* nt/mingw-cfg.site (ac_cv_func_fchmodat)
(gl_cv_func_fchmodat_works, ac_cv_func_lchmod): Disable tests on

This avoids some race conditions (Bug#39683). E.g., if some other
program changes a file to a symlink between the time Emacs creates
the file and the time it changes the file’s permissions, using the
new flag prevents Emacs from inadvertently changing the
permissions of a victim in some completely unrelated directory.
