7 check-ins related to "parser-performance"
|13:24||Enhance Lemon to generate more compact and efficient code for yy_reduce(). Update the main SQL grammar to take advantage of the new capabilities. (check-in: 53fd040c user: drh tags: trunk)|
|12:34||More agressive use of /*A-overwrites-X*/ in the parser. Fix an off-by-one error in parser stack overflow detection. (Closed-Leaf check-in: 417e7777 user: drh tags: parser-performance)|
|04:33||Enhance Lemon so that if reduce code contains a comment of the form "/*A-overwrites-X*/" then a LHS label A is allowed to overwrite the RHS label X. (check-in: 5cfe9545 user: drh tags: parser-performance)|
|01:46||Further improvements to the Lemon-generated code for yy_reduce(). (check-in: ef95a7d6 user: drh tags: parser-performance)|
|01:18||In Lemon, add the ability for the left-most RHS label to be the same as the LHS label, causing the LHS values to be written directly into the stack. (check-in: 4bb94c7c user: drh tags: parser-performance)|
|21:19||Experimental changes to Lemon for improved parser performance. (check-in: a65d583c user: drh tags: parser-performance)|
|13:04||Minor simplification to the tokenizer. Slightly smaller and faster. (check-in: 9570b6b4 user: drh tags: trunk)|
