Parents and children of check-in [ec9b19eb65]

Enhance the Lemon parser generator so that it creates a faster parser at the cost of slightly larger parser tables. Add the ability to measure coverage of the generated state machine when compiling with the -DYYCONVERGE option. In SQLite, add the SQLITE_TESTCTRL_PARSER_COVERAGE test-control to query the new parser coverage feature. check-in: 1b22b42e59 user: drh tags: trunk

The previous check-in had an error in the coverage reporting logic. Closed-Leaf check-in: ec9b19eb65 user: drh tags: lemon-improvements

Change the coverage measurement logic in the lemon-generated parser so that it only checks for coverage of state/lookahead pairs that are valid syntax. It turns out that some states are unreachable if the lookahead is not valid syntax, because the states are only reachable through a shift following a reduce, and the reduce does not happen if the lookahead is a syntax error. check-in: 9dce465087 user: drh tags: lemon-improvements
