* global: remove unnecessary horizontal tabs.Joel E. Denny2011-07-241-8/+8
| | | | | | | | | | | | | | | This change was made by applying emacs' untabify function to nearly all files in Bison's repository. Required tabs in make files, ChangeLog, regexps, and test code were manually skipped. Other notable exceptions and changes are listed below. * bootstrap: Skip because we sync this with gnulib. * data/m4sugar/foreach.m4 * data/m4sugar/m4sugar.m4: Skip because we sync these with Autoconf. * djgpp: Skip because I don't know how to test djgpp properly, and this code appears to be unmaintained anyway. * README-hacking (Hacking): Specify that tabs should be avoided where not required.

(allocate_storgae): Likewise, for shiftset, redset, shift_symbol. * src/closure.c (new_closure): Likewise, for itemset. * src/derives.c (derives_compute): Likewise, for delts, derives, q. * src/lalr.c (set_goto_map): Likewise, for temp_map.

(pack_table): Likewise for base, pos, check. (tables_generate): Likewise for width. * src/LR0.c (set_states): Don't reuse kernel_size and kernel_base for initial core. Just have a separate core, so we needn't worry about whether kernel_size and kernel_base are initialized. * src/LR0.c (shift_symbol, redset, shiftset, kernel_base, kernel_size, kernel_items): Remove unnecessary initialization. * src/conflicts.c (conflicts): Likewise. * src/derives.c (derives): Likewise. * src/muscle_tablc (muscle_insert): Likewise. * src/relation.c (relation_digraph): Likewise. * src/tables.c (froms, tos, conflict_tos, tally, width, actrow, order, conflrow, conflict_table, conflict_list, table, check): Likewise. * src/closure.c (new_closure): Arg is of type unsigned int, not int. This is because all callers pass unsigned int. * src/closure.h (new_closure): Likewise. * src/lalr.c (initialize_F): Initialize reads[i] in all cases. (build_relations): Initialize includes[i] in all cases. * src/reader.c (packgram): Always initialize rules[ruleno].prec and rules[ruleno].precsym.

| | | | | | | | | | | | the pointer DSET returned by malloc; this isn't portable. Instead, always use DSET[i - NTOKENS] rather than DSET[i]. Similarly for DERIVES. (derives_compute): Do not bother invoking int_of_rule_number, since rule numbers are integers. All uses of XCALLOC, XMALLOC, and XREALLOC changed to use new macros CALLOC, MALLOC, REALLOC. All uses of XFREE changed to free.

Strengthen `stage' portability. * m4/stage.m4 (BISON_PREREQ_STAGE): New. * configure.in: Use it. Don't check for malloc.h and sys/times.h. * src/system.h: Include them when appropriate. * src/main.c (stage): Compile only when mallinfo, struct mallinfo, times and struct tms are available.

Adjust all dependencies (pretty many). * src/reduce.c (rule): Remove this `short *' pointer: use item_number_t. * src/system.h (MINSHORT, MAXSHORT): Remove. Include `limits.h'. Adjust dependencies to using SHRT_MAX and SHRT_MIN. (shortcpy): Remove. (MAXTABLE): Move to... * src/output.c (MAXTABLE): here.

| | | | | | | | | | | | | | | | Bison's `allocate.c' and `alloc.h'. This patch was surprisingly difficult and introduced a lot of core dump. It turns out that Bison used an implementation of `xmalloc' based on `calloc', and at various places it does depend upon the initialization to 0. I have not tried to isolate the pertinent places, and all the former calls to Bison's `xmalloc' are now using `XCALLOC'. Someday, someone should address this issue. * src/allocate.c, src/alloc.h, m4/bison-decl.m4: Remove. * lib/xmalloc.c, lib/xalloc.h, m4/malloc.m4, m4/realloc.m4: New files.
