afdc0c9dc8 assignable return value now lives in ast_function, as globals can get overwritten randomly; removed parser_find_retval; updated parse_return 2013-05-29 16:51:59 +02:00
Dale Weiler
6d6a2efada Experimental support for implicit return assignments. This closes #107. To enable return assignment support use -freturn-assignments. This allows you to do the following in QC code. T name() { return = expr_eval_T; return; /* returns expr_eval_T */ }. It allows for concise code and to rid locals in functions. It also saves a tremendous amount of space since only types of certian globals need to be allocated for returns. 2013-05-29 11:13:42 +00:00

f892b32335 Major export cleanup. Anything that was exported but wasn't used outside where it was implemented has been turned into static, and their exports have been removed. This actually makes the compiler compile slightly faster. 2013-05-29 03:29:04 +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

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
