Release 0.3.5:
|
|
* Preprocessor:
|
|
- Added warning for when preprocessor directives are used in
|
|
a macro.
|
|
* Language:
|
|
- Added vector bit operations.
|
|
- Added vector cross product operator `><` for -std=gmqcc.
|
|
- Added `[[eraseable]]` attribute.
|
|
- Removed &~= operator for -std=gmqcc.
|
|
- #pragmas which are ignored are actually ignored to EOL.
|
|
* Compilation:
|
|
- Fixed constant folding.
|
|
- Fixed column printing in diagnostics.
|
|
- Added support for columns in LNOF.
|
|
- Shadowed locals fix.
|
|
- Improved warning diagnostics for precedence usage and other
|
|
various diagnostics.
|
|
- Added constant folding logic for builtin functions.
|
|
- Prevent divide by zero in constant folding.
|
|
- Added unary elision optimization, cases where a unary expression
|
|
cancels itself out, e.g `-(-a)` now simplifies to `a`.
|
|
- Added strength reduce optimization, for divisions e.g `(A / 10)`
|
|
now strength reduces to `(A * (1 / 10)` where `(1 / 10)` is
|
|
evaluated at compile time.
|
|
- Added superfluous expression elision optimization, e.g `(A + 0),
|
|
(A - 0), (A * 1), (A / 1)` can be simplified to just `A`.
|
|
- Quake world now compiles with -std=qcc
|
|
- Constant folding for `if than` now works for ternary expressions
|
|
too.
|
|
- Fixed `[[alias]]` attribute type checking, now you can't alias
|
|
invalid types.
|
|
* QCVM:
|
|
- Properly exits on error now.
|
|
* Lexer:
|
|
- Now prints the character the lexer fails on instead of the
|
|
token value.
|
|
* Testsuite:
|
|
- Important fixes to the testsuite (removal of false positives
|
|
and false negitives).
|
|
- Added a new utility `check-proj.sh` which downloads various Quake
|
|
mods and attempts to compile them.
|
|
* Commandline:
|
|
- Made -fshort-logic, -funtyped-nil and -fvariadic-args default
|
|
for -std=gmqcc.
|
|
* Build:
|
|
- Generate PDFs of man documents for Windows releases.
|
|
- Archlinux/Archbsd package now generates MTREE.
|
|
* Documentation:
|
|
- Fixed mdoc(s).
|
|
* Misc:
|
|
- Added some export scripts for xonotic and nexuiz which generate
|
|
specially crafted packages that are used by the check-proj script.
|
|
|
|
2013-08-20 v0.3.0
|
|
* Language:
|
|
- Return assignments, the ability to assign to the return keyword
|
|
as if it were a local variable.
|
|
- Added bitwise XOR operator (^)
|
|
- Array initializers: e.g float a[] = {1, 2, 3};
|
|
- Fix bug that dissalowed language operators to be used in strings.
|
|
* Compilation:
|
|
- Optimized memory usage (now uses on average %3 less memory for
|
|
compilation).
|
|
- Fixed dotranslate (translatable strings)
|
|
- Rewrote constant folding optimization pass for the parser.
|
|
- New additional dead-code-elimination-consatant-fold pass for
|
|
if statements whos expression can be evaluated at compile-time
|
|
(allowing the if/else branch to be entierly elided at compile-time).
|
|
- Added support for columns in error diagnostics.
|
|
- Limit corrector to <= 16 byte strings.
|
|
- Improved hash function for hashtable (old hash function had 15% error,
|
|
this speeds up compilation)
|
|
- Improved performance of in-house allocator with branch-hinting, speeds
|
|
up compilation of Xonotic by 3 seconds!
|
|
* QCVM:
|
|
- Escape strings for -printdefs
|
|
* Commandline:
|
|
- Added statistic dumps, gives information about the number of used
|
|
hashtables, vectors, and number of unique sizes of vectors and
|
|
hashtables. The amount of memory used for vectors. As well as the
|
|
number of strdups used in total for compilation.
|
|
- Added compile statistic dumps, gives information about the compiled
|
|
binary, and LNO, such as the size, CRC, the number of times a
|
|
specific optimization was applied, etc.
|
|
- Make -std=qcc default.
|
|
* Testsuite:
|
|
- Fixed a floating point exception rasied by modulo operation in
|
|
-memchk.
|
|
- Added support for the test-suite to source tests and task-template
|
|
files from subdirectories in the test/ directory.
|
|
- Now prints the number of failed tests (if any) after all tests
|
|
are attempted.
|
|
- Fixed some bugs with error handling resulting in false-positives.
|
|
* Build:
|
|
- Can now be compiled with TCC (Tiny C compiler) and function as
|
|
intended (previously couldn't due to bug in TCC codegen).
|
|
- Added Gentoo ebuilds.
|
|
- Added Win32 Makefile for building Win32 packages.
|
|
- Added Slackware pkg build files.
|
|
- Added Fedora spec files.
|
|
- Added Makefile for the BSD make variant.
|
|
* Misc:
|
|
- Added valgrind memcheck hook to in-house allocator to help aid
|
|
in finding invalid reads/writes, and more accurate leaks.
|
|
|
