092067482f added -fdefault-eraseable which is the same as adding [[eraseable]] to all definitions 
instead the opposite behavior can be controlled with [[noerase]] attribute

bbeb2517c0 Arithmetic exception flag and a plethora of tests. 2014-05-24 10:38:02 -04:00
Dale Weiler
6424ebaf98 Perliminary work on arithmetic exception handling in the constant evaluator. We can safely check for arithmetic underflow, overflow, divison by zero and inexactness now. Inexactness of expressions are propagated through the AST such that using an inexact value in a comparison will trigger a warning with -Winexact-compares. 2014-05-24 09:53:38 -04:00

4ff68e07e8 Adding coverage support: 
The -coverage option causes all values have AST_FLAG_BLOCK_COVERAGE
set by default.
The coverage attribute can be used to control coverage:
It takes an optional list of coverage types, currently only "block"
and "none" is recognized.
[[coverage]] defaults to [[coverage(block)]].
Use [[coverage(none)]] or [[coverage()]] to disable.

94e477e466 Added -progsrc commandline switch to specify progs.src files of different names. Cleaned up xonotic export script, fixed check-doc on linux systems by disabling mandoc check. 2013-09-12 17:06:20 -04:00

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.

91c7209146 Track constant folds in opts_optimization list .. this could be handled better I assume. 2013-08-15 03:45:50 +00:00
Dale Weiler
6f749d61b1 Added -Oconst-fold-dce (dead code elimination optimization for when constant expressions form the basis of the dead code, i.e if else with constant expression). Fixed deps and added documentation. Cleaned up folds for ir_value (can now use the same macros as the ast_value ones). 2013-08-01 07:07:59 +00:00

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

f2b21158d8 Rewrote memory tracking, now prints highest water mark (most used memory at a given time during compile). Changes all byte representation to MB representation. Added ability to print the contents of the leaked memory to the console when -debug is on (infact the lost messages only print during -debug), -memchk simply reports the memory info at the end (it is also printed when -debug). You can set the memory dump columns with -memdumpcols=# where # is the number of columns you want (default is 16) 2013-04-15 20:54:53 +00:00

480b2fc7b6 Added documentation to all options inside the binary itself. These will be used later for "man/nroff -man"-like documentation on OSs that lack "man" and the concept of system wide documentation. Also it will be nice to add -Wsome_warning help (to get some help about a specific warning/error, etc). 2013-01-30 02:56:58 +00:00
