69252071ba Prevent divide by zero for / and % operations in constant folding (previously caused compiler SIGFPE), instead "inf" is generated for both cases. This closes #124 2013-08-31 12:57:24 -04:00

9032e78349 There is no bug since the testsuite uses -o for preprocessed output (thus the printf never gets involved) if the testsuite read the preprocessor output from stdout than things would be wrong, since however it isn't there is no bug. 2013-08-31 09:53:19 -04:00

51ef277e21 Fix folding logic for conditions. 2013-08-29 00:18:48 -04:00

a7c1f6f021 Implement [[eraseable]] attribute. When used with a function it instructs the AST (which than transfers logic to the IR) that the function (or variable) is potentially unused (verified by checking the read count). This than propogates through the IR and prevents the IR from generating both the definition and global/function. The intrinsics system uses this as well to prevent intrinsic functions from being generated unless they're used. 2013-08-29 00:05:37 -04:00

3b4a5667ea Constant fold intrinsics if their arguments are constant. TODO: reference count intrinsics such that they're not generated unless they're used, currently when an intrinsic can be folded-away it's marked for generation and makes it to the final output binary even though it isn't used. 2013-08-28 12:46:22 -04:00

494c30a239 allow initializing shadowed locals outside of -std=gmqcc - in this case it becomes a regular assignment to the old declaration which is consistent with fteqcc 2013-08-28 14:20:33 +02:00

f4f805f4c9 New options: -ftypeless-stores and -fsort-operands 
These flags reduce entropy, but not size, of the generated assembly
code. This helps compressability of the files.

Additionally, -ftypeless-stores might SLIGHTLY improve engine
performance due to less instructions being used (so branch prediction
might work better). Probably cannot be measured though.
