- 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)
- Fix uses of ctype functions (ex: isspace()) on signed characters in test programs and in some obscure extensions. No changes to the core. (user: drh)
- 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)
- 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)
- 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)
- 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)
- 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)
- 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
- 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)
- Add a missing check for out-of-memory in the lemon code generator.
- Fix a total unimportant file descriptor leak in lemon. This is to silence warning messages.
- Fix a bug in lemon in computation of which non-terminals can generate an empty string. This bug and the fix make absolutely no difference for the grammar used by SQLite, but it can make a difference when lemon is used in other grammars.
- In Lemon, when comparing the output to the *.h file to see if it has changed, make sure that the proposed new output and the preexisting output are the same size before deciding that they are the same.
CMake 2.4, since the distros don't seem to consider 2.6 stable yet.
As a bonus, GTK+ is no longer a required dependency; now it's optional.
- Made dehsupp ignore CR characters, so it doesn't spew warnings on Linux.
SVN r1092 (trunk)
surprised if this doesn't build in Linux right now. The CMakeLists.txt
were checked with MinGW and NMake, but how they fair under Linux is an
unknown to me at this time.
- Converted most sprintf (and all wsprintf) calls to either mysnprintf or
FStrings, depending on the situation.
- Changed the strings in the wbstartstruct to be FStrings.
- Changed myvsnprintf() to output nothing if count is greater than INT_MAX.
This is so that I can use a series of mysnprintf() calls and advance the
pointer for each one. Once the pointer goes beyond the end of the buffer,
the count will go negative, but since it's an unsigned type it will be
seen as excessively huge instead. This should not be a problem, as there's
no reason for ZDoom to be using text buffers larger than 2 GB anywhere.
- Ripped out the disabled bit from FGameConfigFile::MigrateOldConfig().
- Changed CalcMapName() to return an FString instead of a pointer to a static
buffer.
- Changed startmap in d_main.cpp into an FString.
- Changed CheckWarpTransMap() to take an FString& as the first argument.
- Changed d_mapname in g_level.cpp into an FString.
- Changed DoSubstitution() in ct_chat.cpp to place the substitutions in an
FString.
- Fixed: The MAPINFO parser wrote into the string buffer to construct a map
name when given a Hexen map number. This was fine with the old scanner
code, but only a happy coincidence prevents it from crashing with the new
code
- Added the 'B' conversion specifier to StringFormat::VWorker() for printing
binary numbers.
- Added CMake support for building with MinGW, MSYS, and NMake. Linux support
is probably broken until I get around to booting into Linux again. Niceties
provided over the existing Makefiles they're replacing:
* All command-line builds can use the same build system, rather than having
a separate one for MinGW and another for Linux.
* Microsoft's NMake tool is supported as a target.
* Progress meters.
* Parallel makes work from a fresh checkout without needing to be primed
first with a single-threaded make.
* Porting to other architectures should be simplified, whenever that day
comes.
- Replaced the makewad tool with zipdir. This handles the dependency tracking
itself instead of generating an external makefile to do it, since I couldn't
figure out how to generate a makefile with an external tool and include it
with a CMake-generated makefile. Where makewad used a master list of files
to generate the package file, zipdir just zips the entire contents of one or
more directories.
- Added the gdtoa package from netlib's fp library so that ZDoom's printf-style
formatting can be entirely independant of the CRT.
SVN r1082 (trunk)
might still be present in the texture manager; I don't remember.)
- Fixed: EndSequence needs a proper constructor.
- Some more GCC warning removals.
