This avoids spurious library rebuilds when only the test program code is changed and simplifies the build system.

* commit '50078c1c8070dd8d1c329e8117ff30ec72489039': libavutil: move FFALIGN macro from common.h to macros.h Merged-by: Hendrik Leppkes <h.leppkes@gmail.com>
2015-12-14libavutil: move FFALIGN macro from common.h to macros.hJanne Grunau
Include macros.h explicitly in common.h so that external code using FFALIGN does not break. It was already implicitly included through version.h. Include macros.h in lls.h and internal.h for FFALIGN. lls.h was including common.h only for FFALIGN and internal.h was missing the include for FFALIGN. `make checkheaders` did not catch it because it's an internal header.
2015-11-26avutil/lls: speed up performance of solve_llsGanesh Ajjanagadde
This is a trivial rewrite of the loops that results in better prefetching and associated cache efficiency. Essentially, the problem is that modern prefetching logic is based on finite state Markov memory, a reasonable assumption that is used elsewhere in CPU's in for instance branch predictors. Surrounding loops all iterate forward through the array, making the predictor think of prefetching in the forward direction, but the intermediate loop is unnecessarily in the backward direction. Speedup is nontrivial. Benchmarks obtained by 10^6 iterations within solve_lls, with START/STOP_TIMER. File is tests/data/fate/flac-16-lpc-cholesky.err.
