ef528d6710 Added tracing to strdup for allocations, fixed some memleaks, this isn't pretty (trying to track down some weird memory leak issues) 2013-04-14 23:51:16 +00:00
Dale Weiler
cbeac3e5f2 Implemented smart intrinsic / builtin system. When you use trivial math functions like "pow", if they don't exist as a builtin, the compiler will implement its own versions, likewise, if a compiler builtin depends on a function that exists, it will use it, likewise if it doesn't it will implement it. If you explicitally use __builtin_ (prefixed) versions, the compiler again will select the best option it can, be it a combination of both builtins and compiler builtins, all compiler builtins, OR, all builtins (most performant). 2013-03-09 08:53:39 +00:00
Dale Weiler
d8d78f61a7 Implemented "reverse" enum attribute, e.g enum : reverse { A, B, C, D } -> A,B,C,D = 3,2,1,0 2013-03-09 05:07:14 +00:00

662612d66f Better diagnostic when "floor" cannot be found. 2013-03-08 09:23:35 +00:00
Dale Weiler
f19adcd1b3 Implemented __builtin_mod, and % operator. Added floor builtin to the standalone executor. Mod works so long as the compiler can find a suitable definition of "float floor(float)", otherwise it prints a diagnostic and gives up (original id1 Quake had floor so we can depend on it). 2013-03-08 09:17:54 +00:00
Dale Weiler
b971ddec3a Implemented concept of enumeration attributes (can be further extended, but currently only "flag" is implemented as an attribute). An enumeration with a flag attribute will act as a "flagged enumeration", one that automatically handles exponentiation of the constants defined inside it, i.e enum : flag { A, B, C }, A,B,C will equal 2, 4, 8. 2013-03-08 08:01:45 +00:00
Dale Weiler

Dale Weiler
12340a6bd0 Actually generate an ast_call for __builtin_pow for the ** operator, otherwise the operator yeilds a ast_function, making "a ** b" not work, but since it's a function, allows **(a, b). Also added tests for exponentiation operator. 2013-03-07 23:05:40 +00:00
Dale Weiler
d3c7b6fb39 Implement exponentiation operator ** as well as __builtin_pow (used for exponentiation operator). Use of exponentiation operator with constants results in const folded (precomputed at compile time exponentiation), otherwise runtime exponentiation with some clever loops (slow!). 2013-03-07 21:31:19 +00:00

Dale Weiler
21e890602d Fix alias bug. Implemented support for aliases of vectors (x, y, z components). Also made aliases corrector resident (e.g alias to vector foo, named bop, indexing bol_x [instead of bop_x] will result in a correction suggestion of bop_x now). 2013-02-06 09:09:47 +00:00
