From 355e7c1cd1341e7caa4b57536abd1124da2f2ba2 Mon Sep 17 00:00:00 2001 From: Akim Demaille Date: Mon, 8 Apr 2002 11:46:05 +0000 Subject: [PATCH] * src/gram.h (item_number_t): New, the type of item numbers in RITEM. Note that it must be able to code symbol numbers as positive number, and the negation of rule numbers as negative numbers. 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. (prepare_rules): Use output_int_table to output rhs. * data/bison.simple, data/bison.c++: Adjust. * tests/torture.at (Big triangle): Move the limit from 254 to 500. * tests/regression.at (Web2c Actions): Ajust. Trying with bigger grammars shows various phenomena: at 3000 (28Mb of grammar file) bison is killed by my system, at 2000 (12Mb) bison passes, but produces negative #line number, once fixed, GCC is killed while compiling 14Mb, at 1500 (6.7 Mb of grammar, 8.2Mb of C), it passes. * src/state.h (state_h): Code input lines on ints, not shorts. --- NEWS | 3 +++ tests/torture.at | 4 +++- 2 files changed, 6 insertions(+), 1 deletion(-) diff --git a/NEWS b/NEWS index 4f1f0751..a783d422 100644 --- a/NEWS +++ b/NEWS @@ -3,6 +3,9 @@ Bison News Changes in version 1.49a: +* Large grammars + Are now supported. + * The initial rule is explicit.
