Yann Collet 086b9597d9 added ability to split input files for dictionary training
using command -B#
This is the same behavior as benchmark module,
which can also split input into arbitrary size blocks, using -B#.

Yann Collet 8f26dc3f9c blindfix for Visual
LARGE_INTEGER is not an integer :
https://msdn.microsoft.com/en-us/library/windows/desktop/aa383713(v=vs.85).aspx

Do not take any risk with the structure definition :
use int init = 0; like Mac code

Yann Collet c95c0c9725 modified util::time API
for easier invocation.
- no longer expose frequency timer :
it's either useless, or stored internally in a static variable (init is only necessary once).
- UTIL_getTime() provides result by function return.

Nick Terrell 6ab4d5e904 [bench] Use higher resolution timer on POSIX
The timer used was only accurate up to 0.01 seconds. This timer is accurate up to 1 ns.
It is a monotonic timer that measures the real time difference, not on CPU time.

Decoding buffer size min
2017-09-11 16:20:40 -07:00
Yann Collet 3306bcb0e6 fix #820 : GCC v3.x 32-bits doesn't define 64-bits intrinsic
resulting in undefined symbol error.
Push the requirement to GCC 4 for now.
Another solution, proposed by @NWilson, is to use __LONG_MAX__ instead.
__LONG_MAX__ is a GCC-specific constant, which value is supposed to depend on underlying target hardware (32/64 bits)
Might be better, but seems also more complex, hence more prone to side effects.
Keeping the simple solution for now (just rely on __GNUC__)

Yann Collet ce31004f20 fix following suggestions by @terrelln 2017-09-11 13:12:52 -07:00
Yann Collet b3f33ccfb3 use ZSTD_decodingBufferSize_min() inside ZSTD_decompressStream()
Use same definition as public one
minor : reduce allocated buffer size in some cases
(when frameContentSize is known and == windowSize)
2017-09-09 14:37:28 -07:00
Yann Collet 058ed2ad33 ZSTD_decodingBufferSize_min()
supporting function for bufferless streaming API (ZSTD_decompressContinue())
makes it possible to correctly size a round buffer for decoding using this API.

also : added field blockSizeMax within ZSTD_frameHeader,
as it's a necessary information to know when to restart at beginning of decoding buffer.
