| * Make FOR_EACH_TAIL more like other FOR_EACH macrosPaul Eggert2017-02-063-111/+123
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | See comments by Stefan Monnier in: http://lists.gnu.org/archive/html/emacs-devel/2017-02/msg00181.html and by Eli Zaretskii in: http://lists.gnu.org/archive/html/emacs-devel/2017-02/msg00207.html * src/fns.c (internal_equal): Do not bypass check for depth overflow when tail-recursing via a dotted list tail or an overlay plist, to avoid a rare infloop. * src/lisp.h (FOR_EACH_TAIL, FOR_EACH_TAIL_SAFE): Take TAIL as an arg, and update it at each iteration, rather than have callers access it.tail. All callers changed. (FOR_EACH_TAIL): Do not check for dotted lists, as this is now the caller’s responsibility. All callers changed. (FOR_EACH_TAIL_CONS): Remove. All callers changed. (struct for_each_tail_internal.tail): Remove; no longer needed. (FOR_EACH_TAIL_INTERNAL): Remove dotted arg, and set the tail arg each time through the loop. All callers changed.
| * Port to clang 3.8.0Paul Eggert2017-02-051-3/+9
| | | | | | | | | | | | It does not allow a for-loop's control var to be an anonymous struct. * src/lisp.h (struct for_each_tail_internal): New type. (FOR_EACH_TAIL_INTERNAL): Use it.
| * Add cyclic-list testsPaul Eggert2017-02-051-0/+314
| | | | | | | | * test/manual/cycle-tests.el: New file (Bug#25606).
| * FOR_EACH_TAIL now checks for quitPaul Eggert2017-02-051-20/+32
| | | | | | | | | | | | | | | | | | As per Eli Zaretskii (Bug#25606#20). Although these calls to maybe_quit are unnecessary in practice, Eli was not convinced that the calls are unnecessary. * src/lisp.h (FOR_EACH_TAIL, FOR_EACH_TAIL_CONS): Call maybe_quit every so often. (FOR_EACH_TAIL_INTERNAL): New arg CHECK_QUIT. All callers changed.
| * Signal list cycles in ‘length’ etc.Paul Eggert2017-02-054-216/+149
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use macros like FOR_EACH_TAIL instead of maybe_quit to catch list cycles automatically instead of relying on the user becoming impatient and typing C-g (Bug#25606). * src/fns.c (Flength, Fmember, Fmemq, Fmemql, Fassq, Fassoc, Frassq) (Frassoc, Fdelete, Freverse): Use FOR_EACH_TAIL instead of maybe_quit. (Fnreverse): Use simple EQ to check for circular list instead of rarely_quit, as this suffices in this unusual case. (Fplist_put, Flax_plist_put, Flax_plist_put): Use FOR_EACH_TAIL_CONS instead of maybe_quit. (internal_equal): Use FOR_EACH_TAIL_CONS to check lists, instead of by-hand tail recursion that did not catch cycles. * src/fns.c (Fsafe_length, Fplist_get): * src/xdisp.c (display_mode_element): Use FOR_EACH_TAIL_SAFE instead of by-hand Floyd’s algorithm. * src/lisp.h (QUIT_COUNT_HEURISTIC): Remove; no longer needed. (rarely_quit): Simply count toward USHRT_MAX + 1, since the fancier versions are no longer needed. (FOR_EACH_TAIL_CONS, FOR_EACH_TAIL_SAFE) (FOR_EACH_TAIL_INTERNAL): New macros, the last with definiens mostly taken from FOR_EACH_TAIL. (FOR_EACH_TAIL): Rewrite in terms of FOR_EACH_TAIL_INTERNAL.
| * Simplify use of FOR_EACH_TAILPaul Eggert2017-02-053-23/+33
| | | | | | | | | | | | | | | | * src/data.c (circular_list): New function. * src/lisp.h (FOR_EACH_TAIL): Use Brent’s algorithm and C99 for-loop decl, to eliminate the need for the args TAIL, TORTOISE and N, and to speed things up a bit on typical hosts with optimization. All uses changed (Bug#25605).

Hash tables for are declared with :size as the exact number of cases, so each entry i should have a hash code. When BYTE_CODE_SAFE, do it as a sanity check.

| * Re-port alloc.c to Solaris sparc and simplifyPaul Eggert2017-02-021-120/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | alloc.c had bitrotted a bit, and used an undefined symbol stack_base when Emacs was built on Solaris sparc, leading to compilation failures. Also, code related to __builtin_unwind_init was unnecessarily duplicated. Fix the bitrot and remove some duplication. * src/alloc.c: Remove uses of GC_SAVE_REGISTERS_ON_STACK, since it is never defined. (test_setjmp) [!HAVE___BUILTIN_UNWIND_INIT && GC_SETJMP_WORKS]: Define a no-op dummy, to simplify use.

(SET_STACK_TOP_ADDRESS): New macro, containing code that was duplicated. (flush_stack_call_func, Fgarbage_collect): Use it. (init_alloc): Omit unnecessary initialization. After dumping, Emacs need not re-test setjmp.
