de56be6c01 Lemon update 2016-04-29 11:28:35 on branch trunk 
— Lemon bug fix: Do not merge action routines unless their destructors are
also identical. Problem and suggested fix reported on the mailing list by
Kelvin Sherlock. (user: drh)

4641549e0e Lemon update 2016-03-16 19:45:54 on branch trunk 
- Enhance Lemon so that it reorders the reduce rules such that rules without actions occur at the end and so that the first rule is number 0. This reduces the size of the jump table on the reduce switch, and helps the parser to run faster. (user: drh)

4a24f7adcf Lemon update 2016-02-17 12:34:03 on branch parser-performance 
- More agressive use of /*A-overwrites-X*/ in the parser. Fix an off-by-one error in parser stack overflow detection. (user: drh)

25972d79a7 Lemon update 2016-02-17 04:33:10 on branch parser-performance 
- 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. (user: drh)

8a18e5c7eb Lemon update 2016-02-17 01:18:33 on branch parser-performance 
- 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. (user: drh)

7306279a87 Lemon update 2016-02-16 01:01:43 on branch trunk 
- Improve the Lemon parser template (lempar.c) so that it avoids unnecessary work when the grammer defines YYNOERRORRECOVERY (as SQLite does). Slightly smaller and faster code results. (user: drh)

e9501e8688 Lemon update 2015-11-09 19:33:42 on branch parser-enhancements 
- Change the parser to use the standard "lempar.c" template over in the tool/ folder rather than the customized "lempar.c" found in src/. (user: drh)

59b14415ff Lemon update 2015-11-09 15:06:26 on branch trunk 
- Avoid recursion in the yy_find_shift_action() routine of the Lemon-generated parser, so that routine can be inlined, for a size reduction and performance increase. (user: drh)

bcdef59c3c Lemon update 2015-11-09 14:11:37 on branch trunk

fd3507c4c3 Lemon update 2015-09-07 19:52:55 on branch lemon-update 
- Change the parser engine so that it (once again) waits for a lookahead token before reducing, even in a SHIFTREDUCE action. (user: drh)

Randy Heit
3d5867d29e Lemon update 2015-09-07 18:23:37 on branch lemon-update 
- For the Lemon-generated parser, add a new action type SHIFTREDUCE and use it to further compress the parser tables and improve parser performance. (user: drh)

2b5cef0c17 Lemon update 2015-09-07 14:22:24 on branch trunk

9413ea15b6 Lemon update 2015-01-01 19:11:22 on branch trunk 
- Enhance the "lemon" executable so that it ignores -f, -W, -O, and -I command-line options. This permits most of the same options that are passed to the compiler to also be harmlessly passed to lemon, and thus simplifies makefiles. (user: drh)

06455b49c0 Lemon update 2014-06-09 13:11:40 on branch trunk 
- Modify the %nonassoc directive in lemon so that it generates a run-time error rather than a parsing conflict. This changes is due to a bug report on the mailing list. SQLite does not use the %nonassoc directive in its grammar so this change does not affect SQLite. (user: drh)

dd0d0e036c Lemon update 2014-01-11 12:52:25 on branch trunk 
- In LEMON, limit the size of the grammar file to 100MB. This ensures that the program will never experience integer overflow. To be doubly sure, use calloc() instead of malloc() when allocating arrays. (user: drh)

Randy Heit
e59ef08cc8 Lemon update 2014-01-11 03:06:18 on branch lemon-updates 
- Add the new "%token_class" directive for defining symbolic names that stand any one of a collection of tokens. (user: drh)

Randy Heit
249aed455b Lemon update 2013-10-02 20:46:30 on branch trunk 
- In the lemon parser generator, change all hashes to unsigned to avoid potential problems with signed integer overflow. (user: drh)

cb7eb1abc5 Lemon update 2010-07-19 01:52:07 on branch trunk 
- Improvements to the formatting of parse.out file from Lemon. Add the -r option to Lemon to disable the state sorting, making debugging easier. (user: drh)

e20dc913b7 Lemon update 2010-07-18 11:35:53 on branch trunk

a656bb4f72 Lemon update 2010-02-14 00:48:50 on branch lemon-update-2010

1c592c9601 Lemon update 2009-11-03 19:18:32 on branch trunk 
- Enhancements to lemon to generate more compact action tables and to avoid making array bounds tests that can never fail on action table calculations. (user: drh)
- Update zcc-parse.lemon: YY_SZ_ACTTAB is now YY_ACTTAB_COUNT

cafbc8b50a Lemon update 2009-11-03 13:02:26 on branch trunk 
- Adjust the lemon implementation so that it always computes the same PDA regardless of qsort() implementation on the host platform. In other words, make all sorts in lemon stable. (user: drh)

44a6cafd4b - we are using C++11 now, so all those old VC 2005 project files are of no use anymore. 2016-03-01 09:38:49 +01:00

dce3f0f757 - Bump CMake version requirement to 2.8.7. This means that generator expressions must be supported as well as empty else and endif expressions (like most sane languages). ZDoom probably didn't work with 2.4 anymore anyway. 2016-02-05 21:19:29 -05:00

18de376edf - Fixed lemon trying to free non-allocated memory. 
This is a regression from commit 24a096fb27 . It happened only the input files were present in the same directory as the executable.

49edd7c60c - Add support for cross compiling so that OS X PowerPC builds can still be made on systems without rosetta (10.7+). (Compiling x86 binaries on ppc should also be possible.) 2014-01-02 01:59:04 -05:00
