It provides the following features: * verify correctness by comparing output to the C version. * detect failure to save and restore clobbered callee-saved registers. * detect 32-bit parameters being used as if they were 64-bit in x86-64 (the upper halves are not guaranteed to be zero - but in practice they very often are, which makes those bugs hard to spot otherwise). * easy benchmarking. Compile by running 'make checkasm'. Execute by running 'tests/checkasm/checkasm'. Optional arguments are '--bench' to run benchmarks for all functions, '--bench=<pattern>' to run benchmarks for all functions that starts with <pattern>, and '<integer>' to seed the PRNG for reproducible results. Contains unit tests for most h264pred functions to get started, more tests can be added afterwards using those as a reference. Loosely based on code from x264. Currently only supports x86 and x86-64, but additional architectures shouldn't be too much of an obstacle to add. Note that functions with floating point parameters or floating point return values are not supported. Some compiler-specific features or preprocessor hacks would likely be required to add support for that. Signed-off-by: Janne Grunau <janne-libav@jannau.net>
