* Update from GnulibPaul Eggert2021-10-041-0/+18
| | | | | | | | | | | | | | | | | | Make the following changes by hand, and run 'admin/merge-gnulib'. * .gitignore: Add lib/malloc/*.gl.h. * admin/merge-gnulib: Copy lib/af_alg.h and lib/save-cwd.h directly from Gnulib, without worrying about Gnulib modules, as these files are special cases. (AVOIDED_MODULES): Remove malloc-posix. * lib/malloc.c, lib/realloc.c, m4/malloc.m4, m4/realloc.m4: * m4/year2038.m4: New files, copied from Gnulib. * lib/malloca.c, lib/malloca.h: * m4/close-stream.m4, m4/glibc21.m4, m4/malloca.m4: Remove. These are either no longer present in Gnulib, or are no longer needed by modules that Emacs uses. * oldXMenu/AddPane.c, oldXmenu/Addsel.c: Include XmenuInt.h first; needed for new Gnulib. * src/xmenu.c: Call emacs_abort, not abort.
* logb now works correctly on large integersPaul Eggert2017-03-031-0/+3
* admin/merge-gnulib (GNULIB_MODULES): Add count-leading-zeros. * etc/NEWS: Document the change. * lib/count-leading-zeros.c, lib/count-leading-zeros.h: * m4/count-leading-zeros.m4: New files, copied from Gnulib. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * src/floatfns.c: Include count-leading-zeros.h. (Flogb): Do not convert fixnum to float before taking the log, as the rounding error can cause the answer to be off by 1. * src/lisp.h (EMACS_UINT_WIDTH): New constant. * test/src/floatfns-tests.el (logb-extreme-fixnum): New test.
