-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.

- - 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.

- invalid types.

- mods and attempts to compile them.

- - Fixed dotranslate (translatable strings)
- - Rewrote constant folding optimization pass for the parser.

- - Limit corrector to <= 16 byte strings.
- - Improved hash function for hashtable (old hash function had 15% error,
- this speeds up compilation)

-GMQCC is quite feature complete. But that doesn't address the fact that
-it can be improved. This is a list of things that we'd like to support
-in the distant future. When the time comes, we can just select a topic
-from here and open a ticket for it on the issue tracker. But for the
-meantime, this is sort of a cultivating flat file database.
-
-Optimizations:
- The following are optimizations that can be implemented after the
- transformation into static-single assignment (SSA).
-
- Global Value Numbering:
- Eliminate redundancy by constructing a value graph of the source
- then determining which values are computed by equivalent expressions.
- Similar to Common Subexpression Elimination (CSE), however expressions
- are determined via underlying equivalence, opposed to lexically identical
- expressions (CSE).
-
- The following are optimizations that can be implemented before the
- transformation into a binary (code generator).
-
- Code factoring:
- The process of finding sequences of code that are identical,
- or can be parameterized or reordered to be identical.
- Which can be replaced with calls to a shared subroutine. To
- reduce duplicated code. (Size optimization)
-
-Language Features:
- The following are language features that we'd like to see implemented in the
- future.
-
- AST Macros:
- Macros with sanity. Not textual substiution.
-
- Classes:
- Like C++, but minus the stupidity:
- - No type operator overloads
- - Keep operator overloading for basic operators though.
- - No inheritance
- - No virtuals / pure virtuals
- - Essentially "C structs but with operators" :)
-
- Overloaded Functions:
- Ability to make individual functions with the same name, but take
- different amount of arguments or type of arguments.
-
- Default Argument Substiution:
- Ability to specify default values for arguments in functions.
- void foo(string bar, string baz="default");
- Supplying just one argument will expand the second argument to
- become "default", otherwise if two arguments are specified then
- the "default" string is overrode with what ever the user passes.
-
- Namespaces:
- There is already a ticket open on this. They'd work just like C++
- identically even.
-
-Testsuite:
- The following are things we'd like to see added to the testsuite
- in the distant future:
-
- Interface:
- Ability to select individual tests, or set parameters manually
- opposed to using the static task-template files. (A method to
- override them rather).
