alexey.lysiuk 28e6477a03 Made Lemon's dynamic stack size compatible with C++ 2017-07-23 11:54:16 +03:00
Marisa Heit f23e5d2677 Fixed: XLAT would not parse
- Disable the changes from commit 96afce241d
  because it appears to not recognize default rules that reduce as
  reducing.
- When tracing a parser, flush after every line output in case an
  assert is hit so you can actually see what it did up to that point.

Marisa Heit 97107b6b6d Update lempar.c to 2016-10-04 version
- Every update rolled into one, because I'm pretty sure I missed some while
updating lemon.c (not counting today's commits), since it wasn't always
updated at the same time as lemon.c.
- In particular, I think this check-in from 2016-06-06 was very important to
  us after commit 3d5867d29e (For the
  Lemon-generated parser, add a new action type SHIFTREDUCE and use it to
  further compress the parser tables and improve parser performance.):
  * Fix lempar.c so that the shift-reduce optimization works for error
    processing.

Randy Heit 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)

Randy Heit 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)

Randy Heit 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)

Randy Heit 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)

Randy Heit 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)

- Update zcc-parse.lemon: YY_SZ_ACTTAB is now YY_ACTTAB_COUNT
2016-03-20 13:06:43 -05:00
Randy Heit ec364c53c1 - Update Lemon to the latest SQLite CVS versions:

SVN r2172 (scripting)
2010-02-21 04:33:08 +00:00
Randy Heit a9ffb9140c - Fixed: lempar.c needs to specify the __cdecl calling convention for malloc
and free under VC++.


SVN r820 (trunk)
2008-03-19 23:53:06 +00:00
Randy Heit ec17f5a5b9 - Undid some of the changes from lempar.c v1.30->v1.31, because it broke
error handling.
- Fixed: dehsupp/scanner.re defined "}" as the token RPAREN. dehsupp/parse.y
  also defined action_list_def as needing a RBARCE. I'm surprised it worked
  at all before. I guess Lemon really was too accepting.
- Changed the way that xlatcc handles include statements so that I don't need
  to modify the logic of lempar.c. I also discovered that the grammar was
  improperly defined and only accepted the first statement. It worked before
  because Lemon used to accept multiple times before reaching the EOF token.
  I have also verified that it is still generating the proper lumps.
- Removed some unused wadsrc files from the repository.
- Fixed my re2c upgrade.
- Updated lemon.c to v1.53.

SVN r711 (trunk)
2008-01-26 04:33:34 +00:00
Randy Heit e5572a1c4e - Updated lempar.c to v1.31.
- Added .txt files to the list of types (wad, zip, and pk3) that can be
  loaded without listing them after -file.
- Fonts that are created by the ACS setfont command to wrap a texture now
  support animated textures.
- FON2 fonts can now use their full palette for CR_UNTRANSLATED when drawn
  with the hardware 2D path instead of being restricted to the game palette.
- Fixed: Toggling vid_vsync would reset the displayed fullscreen gamma to 1
  on a Radeon 9000.
- Added back the off-by-one palette handling, but in a much more limited
  scope than before. The skipped entry is assumed to always be at 248, and
  it is assumed that all Shader Model 1.4 cards suffer from this. That's
  because all SM1.4 cards are based on variants of the ATI R200 core, and the
  RV250 in a Radeon 9000 craps up like this. I see no reason to assume that
  other flavors of the R200 are any different. (Interesting note: With the
  Radeon 9000, D3DTADDRESS_CLAMP is an invalid address mode when using the
  debug Direct3D 9 runtime, but it works perfectly fine with the retail
  Direct3D 9 runtime.) (Insight: The R200 probably uses bytes for all its
  math inside pixel shaders. That would explain perfectly why I can't use
  constants greater than 1 with PS1.4 and why it can't do an exact mapping to
  every entry in the color palette.
- Fixed: The software shaded drawer did not work for 2D, because its selected
  "color"map was replaced with the identitymap before being used.
- Fixed: I cannot use Printf to output messages before the framebuffer was
  completely setup, meaning that Shader Model 1.4 cards could not change
  resolution.
- I have decided to let remap palettes specify variable alpha values for
  their colors. D3DFB no longer forces them to 255.
- Updated re2c to version 0.12.3.
- Fixed: A_Wander used threshold as a timer, when it should have used
  reactiontime.
- Fixed: A_CustomRailgun would not fire at all for actors without a target
  when the aim parameter was disabled.
- Made the warp command work in multiplayer, again courtesy of Karate Chris.
- Fixed: Trying to spawn a bot while not in a game made for a crashing time.
  (Patch courtesy of Karate Chris.)
- Removed some floating point math from hu_scores.cpp that somebody's GCC
  gave warnings for (not mine, though).
- Fixed: The SBarInfo drawbar command crashed if the sprite image was
  unavailable.
- Fixed: FString::operator=(const char *) did not release its old buffer when
  being assigned to the null string.
- The scanner no longer has an upper limit on the length of strings it
  accepts, though short strings will be faster than long ones.
- Moved all the text scanning functions into a class. Mainly, this means that
  multiple script scanner states can be stored without being forced to do so
  recursively. I think I might be taking advantage of that in the near
  future. Possibly. Maybe.
- Removed some potential buffer overflows from the decal parser.
- Applied Blzut3's SBARINFO update #9:
  * Fixed: When using even length values in drawnumber it would cap to a 98
    value instead of a 99 as intended.
  * The SBarInfo parser can now accept negatives for coordinates. This
    doesn't allow much right now, but later I plan to add better fullscreen
    hud support in which the negatives will be more useful. This also cleans
    up the source a bit since all calls for (x, y) coordinates are with the
    function getCoordinates().
- Added support for stencilling actors.
- Added support for non-black colors specified with DTA_ColorOverlay to the
  software renderer.
- Fixed: The inverse, gold, red, and green fixed colormaps each allocated
  space for 32 different colormaps, even though each only used the first one.
- Added two new blending flags to make reverse subtract blending more useful:
  STYLEF_InvertSource and STYLEF_InvertOverlay. These invert the color that
  gets blended with the background, since that seems like a good idea for
  reverse subtraction. They also work with the other two blending operations.
- Added subtract and reverse subtract blending operations to the renderer.
  Since the ERenderStyle enumeration was getting rather unwieldy, I converted
  it into a new FRenderStyle structure that lets each parameter of the
  blending equation be set separately. This simplified the set up for the
  blend quite a bit, and it means a number of new combinations are available
  by setting the parameters properly.

Randy Heit e8495e90f5 Fixed some lemon bugs:
* "Symbol name missing after %destructor keyword" error message displayed incorrectly.
* Line numbers in the generated file for lines that came from the template were off.
* The parser did not immediately reduce after a shift. There always needed to be
  another token input first before a reduce would occur, and then the token would
  sometimes be lost.

Randy Heit 323034af74 Forgot to update lempar.c with lemon.c, so here is version 1.23 from the SQLite CVS.
SVN r468 (trunk)
2007-01-30 20:33:57 +00:00
Randy Heit 43abfba723 - Modified ccdv-win32 to show "Generating X" messages when running lemon and
re2c instead of "Linking X".
- Updated lemon and re2c to the latest versions and ported dehsupp to use them
  for code generation. (Xlatcc is next.)
- Added function level linking for Makefile.mingw.
