comment:1 by Bruce Dubbs, 3 years ago

  • Noteworthy changes in release 3.7.4 (2020-11-14) [stable]
  • Bug fixes
  • Bug fixes in yacc.c

In Yacc mode, all the tokens are defined twice: once as an enum, and then as a macro. YYEMPTY was missing its macro.

  • Bug fixes in lalr1.cc

The lalr1.cc skeleton used to emit internal assertions (using YY_ASSERT) even when the parse.assert %define variable is not enabled. It no longer does.

The private internal macro YY_ASSERT now obeys the api.prefix %define variable.

When there is a very large number of tokens, some assertions could be long enough to hit arbitrary limits in Visual C++. They have been rewritten to work around this limitation.

  • Changes

The YYBISON macro in generated "regular C parsers" (from the "yacc.c" skeleton) used to be defined to 1. It is now defined to the version of Bison as an integer (e.g., 30704 for version 3.7.4).
