a344e5d094 x86: bswapdsp: Don't treat 32-bit integers as 64-bit 
The upper halves are not guaranteed to be zero in x86-64.

Also use `test` instead of `and` when the result isn't used for anything other
than as a branch condition, this allows some register moves to be eliminated.

4da585ae47 OS/2: Cleanup slib_create_def_cmd 
Export symbols by name rather then ordinal.
Remove PROTMODE directive as it does not make sense for 32 bit library.
Also silences a warning from some linkers.

b9f76d19d8 hevc_ps: make sure failing to decode an SPS always returns an error 
Some of the goto err clauses do not set the error code. It seems better
to fall back on INVALIDDATA instead of adding it everywhere explicitly.

d82e1adc20 hevc: move splitting the packet into NALUs into a separate function

ae05b48655 hevc: eliminate the second call to hls_nal_unit() 
Also, make hls_nal_unit() work only on the provided NAL unit, without
requiring a whole decoding context.

86eee85dad bytestream2: set the reader to the end when reading more than available 
This prevents possible infinite loops with the calling code along the
lines of while (bytestream2_get_bytes_left()) { ... }, where the reader
does not advance.

8bc67ec2c0 Checkasm: assembly testing and benchmarking tool 
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.
