* Unroll base64 decode loop.Reimar Döffinger2012-01-21
| | | | | | | | Around 50% faster. decode: 374139 -> 248852 decicycles syntax check: 236955 -> 123854 decicycles Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
* Use a full table for base64 decode.Reimar Döffinger2012-01-21
| | | | | | | | | Also encodes error or end marker into table. About 20% faster. decode: 466491 -> 374139 decicycles syntax check: 236955 -> 161182 decicycles Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>

* base64: Only run benchmark when "-t" is specified.Michael Niedermayer2012-01-21
| | | | | | | | As the test is run during fate and the benchmark is useless for fate this very slightly speeds up fate. Its also consistent with the other tests. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

* tools: add ffeval toolStefano Sabatini2012-01-17
| | | | | | The tool is useful for testing the internal arithmetic evaluation engine (indeed I plan to use it in FATE), and provides a handy calculator when you can't rely on bc ;-).
* lavu/eval: add if() and ifnot() eval functionsStefano Sabatini2012-01-17
| | | | | | | | | | They allow to implement the if/then/else logic, which cannot be implemented otherwise. For example the expression: A*B + not(A)*C always evaluates to NaN if B is NaN, even in the case where A is 0.

| * lavu: replace int/float punning functionsMans Rullgard2011-12-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing functions defined in intfloat_readwrite.[ch] are both slow and incorrect (infinities are not handled). This introduces a new header with fast, inline conversion functions using direct union punning assuming an IEEE-754 system, an assumption already made throughout the code. The one use of Intel/Motorola extended 80-bit format is replaced by simpler code sufficient under the present constraints (positive normal values). The old functions are marked deprecated and retained for compatibility. Signed-off-by: Mans Rullgard <mans@mansr.com>
