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.

* | | Avoid libgmp aborts by imposing limitsPaul Eggert2018-08-211-166/+148
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libgmp calls ‘abort’ when given numbers too big for its internal data structures. The numeric limit is large and platform-dependent; with 64-bit GMP 6.1.2 it is around 2**2**37. Work around the problem by refusing to call libgmp functions with arguments that would cause an abort. With luck libgmp will have a better way to do this in the future. Also, introduce a variable integer-width that lets the user control how large bignums can be. This currently defaults to 2**16, i.e., it allows bignums up to 2**2**16. This should be enough for ordinary computation, and should help Emacs to avoid thrashing or hanging. Problem noted by Pip Cet (Bug#32463#71). * doc/lispref/numbers.texi, etc/NEWS: Document recent bignum changes, including this one. Improve documentation for bitwise operations, in the light of bignums. * src/alloc.c (make_number): Enforce integer-width. (integer_overflow): New function. (xrealloc_for_gmp, xfree_for_gmp): Move here from emacs.c, as it's memory allocation. (init_alloc): Initialize GMP here, rather than in emacs.c. (integer_width): New var. * src/data.c (GMP_NLIMBS_MAX, NLIMBS_LIMIT): New constants. (emacs_mpz_size, emacs_mpz_mul) (emacs_mpz_mul_2exp, emacs_mpz_pow_ui): New functions.

(check_bignum_size, xmalloc_for_gmp): Remove. * src/emacs.c (main): Do not initialize GMP here. * src/floatfns.c (Fexpt): Use expt_integer, which now contains integer code moved from here. * src/lisp.h (GMP_NUMB_BITS): Define if gmp.h doesn’t.

(Fash): Check for out-of-range counts. If COUNT is zero, return first argument instead of going through libgmp. Omit lsh code since lsh is now done in Lisp. Add code for shifting fixnums right, to avoid a round trip through libgmp. (Flsh): Remove; moved to lisp/subr.el. * test/lisp/international/ccl-tests.el (shift): Test for traditional lsh behavior, instead of assuming lsh is like ash when bignums are present. * test/src/data-tests.el (data-tests-logand) (data-tests-logior, data-tests-logxor, data-tests-ash-lsh): New tests.

* | | Turn misc objects into pseudovectorsPaul Eggert2018-08-111-10/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Eliminate the category of miscellaneous objects, and turn all such objects into pseudovectors. The immediate motivation for this change is to free up an enum Lisp_Type tag value, a scarce resource that can be better used elsewhere. However, this change is worthwhile in its own right, as it improves performance slightly on my platform, 0.3% faster for 'make compile-always' on Fedora 28, and it simplifies the garbage collector and interpreter (Bug#32405). * doc/lispref/internals.texi (Garbage Collection): * etc/NEWS: Document change to garbage-collect return value. * src/alloc.c (total_markers, total_free_markers): (union aligned_Lisp_Misc, MARKER_BLOCK_SIZE) (struct marker_block, marker_block, marker_block_index) (misc_free_list, allocate_misc, live_misc_holding) (live_misc_p, sweep_misc): * src/lisp.h (lisp_h_MARKERP, lisp_h_MISCP, MARKERP, MISCP) (Lisp_Misc, enum Lisp_Misc_Type, Lisp_Misc_Free) (Lisp_Misc_Marker, Lisp_Misc_Overlay, Lisp_Misc_Finalizer) (Lisp_Misc_Ptr, Lisp_Misc_User_Ptr, Lisp_Misc_Limit) (Lisp_Misc_Bignum) (XSETMISC, struct Lisp_Misc_Any, XMISCANY, XMISCTYPE) (struct Lisp_Free, union Lisp_Misc, XMISC): Remove.

This option is more machine-independent, allows formats like "#x%x" to be useful for reading later, and is better-insulated for future changes involving bignums. Setting the new variable ‘binary-as-unsigned’ to nil enables the new behavior (Bug#32252). This is a simplified version of the change proposed in: https://lists.gnu.org/r/emacs-devel/2018-07/msg00763.html I simplified that proposal by omitting bitwidth modifiers, as I could not find an any example uses in the Emacs source code that needed them and doing them correctly would have been quite a bit more work for apparently little benefit. * doc/lispref/strings.texi (Formatting Strings): Document that %x and %o format negative integers in a platform-dependent way.
