f577b99b0e Merge branch 'dev' into xxh128 2019-05-02 15:30:42 -07:00
Yann Collet
6a64e4f17e first xxh128 design 
not terribly fast, but "acceptable" speed

021668b9d0 Port over the VSX version 
Supports both big and little endian.

3622b1496e tested new 64bits accumulator 
disguised as xxh128
 2019-04-25 09:55:10 -07:00
Yann Collet
095c978912 updated XXH128 for long input (> 128B) 
scalar version only for the time being

bef31a75e9 fixed minor gcc warning 
xxh128 tests not restored yet

8b6861ba4c restored self-tests 
most xxh3 tests updated

8ffa196f25 update scrambling 
does no longer depends on secret key's parity.

f2163b8b75 changed algorithm for small inputs 
- seed modifies the key values,
  the value that can trigger a zero multiply is now seed-dependent

- accumulator also receive input as addition,
  cancelling the impact of zero multiply.

Performance on small inputs seems slightly slower, within noise measurement level.

f3d4bf4eef xxh3: ensure all 64-bits of the seed are ingested 
in the len=[1-3] case

cf5694603d Improve xxhsum output message quality 
- xxhsum now prints more professional-looking error messages:
Before:
    Pb opening foo
After:
    Error: Could not open 'foo': No such file or directory.

- xxhsum will now attempt to display the architecture and the compiler
  version in the benchmark WELCOME_MESSAGE.
  It detects the following compilers:
    - Clang
    - GCC
    - Intel Compiler
    - MSVC
    - tcc
  and it should detect the following architectures:
    - x86 (+SSE2/AVX/AVX2)
    - x86_64 (+SSE2/AVX/AVX2)
    - ARM (+NEON)
    - aarch64
    - PowerPC 64
    - PowerPC
    - AVR
    - MIPS 64
    - MIPS
Before:
    ./xxhsum 0.7.0 (64-bits little endian), by Yann Collet
After:
    ./xxhsum 0.7.0 (64-bits x86_64 + SSE2 little endian), GCC 8.3.0, by Yann Collet

- Sanity checks are consistent now and give better warning messages:
Before:
    ERROR : Test  1 : 0x12345678 <> 0x02CC5D05   !!!!!

    ERROR : Test  1 : 64-bit values non equals   !!!!!
     0x1234567890ABCDEFULL != 0xEF46DB3751D8E999ULL
After:
    Error: 32-bit hash test 1: Internal sanity check failed!
    Got 0x12345678, expected 0x02CC5D05.
    Note: If you modified the hash functions, make sure to either update the values
    or temporarily comment out the tests in BMK_sanityCheck.

...and the 64-bit and 128-bit messages now match. I eventually want to name the
tests instead of just using the test number, but this is still better than before.

- xxhsum now displays "stdin" instead of "-" when reading from stdin.

3eb9d18ddb explicitly states when not checking a return value 
although, cppcheck seems to overdo this warning,
as it also warns for function with `void` return type (??)

c3557bcbfd added target make check 
`make test` does not contain platform-specific tests (32-bit, arm, etc.)

`make test-all` still includes them.
