Martin Storsjö	143f1e9203	eval: Add the isinf() function and tests for it Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	3893feeccd	opt/eval: Include mathematics.h for NAN/INFINITY These files use NAN/INFINITY but didn't include mathematics.h to get the fallback definitions if the system lacks the macros. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago

Stefano Sabatini	999495734b	lavu/eval: add if() and ifnot() eval functions They allow to implement the if/then/else logic, which cannot be implemented otherwise. For example the expression: AB + not(A)C always evaluates to NaN if B is NaN, even in the case where A is 0.	13 years ago
Reimar Döffinger	d086c1203c	Add coverage exclusions for test code. For some of the code e.g. doing timing measurements there is no real point in running regression testing on it, thus it should not be counted against coverage. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago

Stefano Sabatini	d2af7205a1	Use hierarchic names convention (prefix them with av_expr) for the eval API. More grep-friendly and more consistent with the rest of the FFmpeg API. Originally committed as revision 25708 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	20fcd0797e	Implement isnan() function evaluation. Originally committed as revision 25666 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	4cabef0a9d	Make strmatch() return 1 only if the string compared against the prefix does not contain other characters which may belong to an identifier. This allows to distinguish for example to have different constants with the same prefix (e.g. "foo" and "foobar"). Originally committed as revision 25626 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	2b59fbe9b1	Add st, ld, while examples/tests. Originally committed as revision 25625 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	8bb12e71af	Add examples of unary operators. Originally committed as revision 25624 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	63b1630356	Fix evaluation of expressions of the form: E1;E2. The pointer to the char ';' has to be increased before to evaluate ";E2". Originally committed as revision 25623 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Stefano Sabatini	eb928286de	Add more tests to eval, help detecting some of the more apparent errors, far from being a complete test system. Originally committed as revision 23635 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	7ec9b9beca	Make av_parse_expr() fail if there are trailing chars at the end of the provided expression. Allow detection of mistyped expressions. Originally committed as revision 23629 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Stefano Sabatini	0b99215c0e	Move eval.c and eval.h from libavcodec to libavutil, and make the eval API public. Originally committed as revision 23485 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
