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).
