Avoid use of uninitialized and uncomputed linear least square models during ff_lpc_calc_coefs() for FF_LPC_TYPE_CHOLESKY. Fixes running make fate-flac-16-lpc-cholesk with valgrind --undef-value-errors=yes.

Start and end index are multiple of 2, therefore guaranteeing aligned access. Also, this allows to generate 4 floats per loop, keeping the alignment all along. Timing: - 32 bits: 326c -> 172c - 64 bits: 323c -> 156c Signed-off-by:

Some shells, e.g. minix3, have a broken 'test' builtin which fails if the first operand of a binary operator looks like a unary operator. Prefixing the values with 'x' prevents this from happening. Signed-off-by:

Any performance gain from this is negligible and not worth the extra code.

There is no point in duplicating this code in every get_buffer() implementation.

It will be useful in the upcoming transition to refcounted AVFrames.

The def files are used for generating import libraries for other toolchains (in particular, for generating import libraries for MSVC for DLLs built with mingw). The def files produced by mingw/gcc contains ordinals for each exported function. When MSVC tools generate import libraries from such a def file, MSVC links to the DLL by the ordinals instead of linking by name. Since the def files aren't maintained by hand, the ordinal numbers are assigned (more or less) randomly and any caller linking to the libs by ordinals will break as soon as the libraries export more/fewer functions. Therefore, strip out the ordinals from the generated def files, to make users link to the libraries by name. Callers linking to the DLLs using the gcc provided import library link by name as they should. Signed-off-by:

They share the same code, so building one w/o the other makes no sense.
