2b5c61dabf Fix build when XXH_DISPATCH_AVX512 isn't defined 
This makes it possible to disable AVX512 by removing the define.

71566dfcee fixed performance issue reported in #398 
also : fixed XXH128_withSecret(),
which was messed up with default `kSecret`.
This error remained unnoticed because their was no test for this variant.
Added a test in `xxhsum` checking results of `XXH128_withSecret()`

a7a617584c introduced --tag for BSD-style output 
hidden option for the time being (undocumented)
as it's only an output format,
there is no ability to `-c` check it yet.

The effort was however useful in refactoring `xxhsum` code base.

One advantage of the `--tag` BSD format is
that it's a lot safer to introduce additional formats.
For example, little and big-endian variants can co-exist safely,
since endianess is clearly expressed as part of the algorithm name.
It would also make it possible to introduce XXH3 (later),
even though it's 64-bit, which would be confusing with XXH64.

Also :
added ability to select algorithm by specifying bit width.
Hence :
H0 == H32 ==> XXH32
H1 == H64 ==> XXH64
H2 == H128==> XXH128

7dd0334054 Some Makefile improvements 
- Fix identification of Cygwin/MSYS/MINGW "OS" that have $(OS) of
  Windows% but shouldn't obey the Windows rules.
- Add Cygwin to the list of validated installs. I ran install as:
  `PREFIX=/usr make install`
- The uninstall target now removes the xxh3.h file.

c5867346ee bench: can select multiple variants 
using comma separated IDs
 2020-06-12 15:07:20 -07:00
Yann Collet
57377539bf can select multiple variants to benchmark 
For example, `xxhsum -b1 -b2` will benchmark XXH32 in both aligned and unaligned mode.

Also : modified default list,
now only test main variants (XXH32, XXH64, XXH3 and XXH128).

Also : -bi0 makes it possible to generate a very quick (though inaccurate) evaluation.
