Paul Eggert f18af6cd5c Audit use of lsh and fix glitches ... I audited use of lsh in the Lisp source code, and fixed the glitches that I found. While I was at it, I replaced uses of lsh with ash when either will do. Replacement is OK when either argument is known to be nonnegative, or when only the low-order bits of the result matter, and is a (minor) win since ash is a bit more solid than lsh nowadays, and is a bit faster. * lisp/calc/calc-ext.el (math-check-fixnum): Prefer most-positive-fixnum to (lsh -1 -1). * lisp/vc/vc-hg.el (vc-hg-state-fast): When testing fixnum width, prefer (zerop (ash most-positive-fixnum -32)) to (zerop (lsh -1 32)) (Bug#32485#11). * lisp/emacs-lisp/bytecomp.el (byte-compile-lapcode): Tighten sanity-check for bytecode overflow, by checking that the result of (ash pc -8) is nonnegative. Formerly this check was not needed since lsh was used and the number overflowed differently. * lisp/net/dns.el (dns-write): Fix some obvious sign typos in shift counts. Evidently this part of the code has never been exercised. * lisp/progmodes/hideif.el (hif-shiftleft, hif-shiftright): * lisp/term/common-win.el (x-setup-function-keys): Simplify. * admin/unidata/unidata-gen.el, admin/unidata/uvs.el: * doc/lispref/keymaps.texi, doc/lispref/syntax.texi: * doc/misc/calc.texi, doc/misc/cl.texi, etc/NEWS.19: * lisp/arc-mode.el, lisp/calc/calc-bin.el, lisp/calc/calc-comb.el: * lisp/calc/calc-ext.el, lisp/calc/calc-math.el: * lisp/cedet/semantic/wisent/comp.el, lisp/composite.el: * lisp/disp-table.el, lisp/dos-fns.el, lisp/edmacro.el: * lisp/emacs-lisp/bindat.el, lisp/emacs-lisp/byte-opt.el: * lisp/emacs-lisp/bytecomp.el, lisp/emacs-lisp/cl-extra.el: * lisp/erc/erc-dcc.el, lisp/facemenu.el, lisp/gnus/message.el: * lisp/gnus/nndoc.el, lisp/gnus/nnmaildir.el, lisp/image.el: * lisp/international/ccl.el, lisp/international/fontset.el: * lisp/international/mule-cmds.el, lisp/international/mule.el: * lisp/json.el, lisp/mail/binhex.el, lisp/mail/rmail.el: * lisp/mail/uudecode.el, lisp/md4.el, lisp/net/dns.el: * lisp/net/ntlm.el, lisp/net/sasl.el, lisp/net/socks.el: * lisp/net/tramp.el, lisp/obsolete/levents.el: * lisp/obsolete/pgg-parse.el, lisp/org/org.el: * lisp/org/ox-publish.el, lisp/progmodes/cc-defs.el: * lisp/progmodes/ebnf2ps.el, lisp/progmodes/hideif.el: * lisp/ps-bdf.el, lisp/ps-print.el, lisp/simple.el: * lisp/tar-mode.el, lisp/term/common-win.el: * lisp/term/tty-colors.el, lisp/term/xterm.el, lisp/vc/vc-git.el: * lisp/vc/vc-hg.el, lisp/x-dnd.el, test/src/data-tests.el: Prefer ash to lsh when either will do.		2018-08-21 13:44:32 -07:00
