e9b91102eb completed tests for streaming with custom secret 
fixed streaming with custom secret on small input

47ce68677a updated selft-test sample generator 
to generate more random bytes (and less zero).

updated tests accordingly.

confirmed XXH3 streaming more works fine (default & seed).

d5e42a6947 improved performance for most compilers 
special case clang's auto-vectorizer for SSE2,
everybody else prefers force_inline.

0556bd2318 completed variant of xxh3 streaming supporting custom secret 
still to be tested
 2019-06-13 18:24:10 -07:00

303572d632 changed streaming API names, adding _64bits 
to better clarify, since there will be a _128bits variant in the future.

Also : fixed streaming variant, all magic numbers have names

Note : does not work yet with custom secret sizes

f9a73ff4bd make secret unaligned for mergeAccs and last accumulate 
so that it's different from scrambler and normal accumulate

1e4aca9718 favor SSE2 auto-vectorization 
changed XXH3_hashLong_internal_loop() directive to `static`

ac897bec29 alignment hint for auto-vectorizer 
works great for AVX2, but not for SSE2 (?)

also : use char* to explicitly tell that no alignment guarantee is being made

also : slightly changed start address of last stripe's secret (-1)
so that it doesn't correspond to scrambler's secret.

0ab31bc636 fixed performance regression for XXH3_64bits() 
better make sure, with inlining,
that secret is clearly understood as being kSecret,
saving some operations.

e90298ab7c replaced readKey64 by readLE64 
to make it more explicit what's happening.

31e15a77e7 removed the power9 test from TravisCI 
check if the VSX code path get triggered nonetheless
 2019-06-12 17:13:23 -07:00
Yann Collet
705e6a1c12 try power8 instead 
because power9 is not available on `trusty` environment,
which is the current environment for PowerPC tests.

5fc33510ff secret is now a blob of bytes with no alignment restriction 
secret must only respect a size condition now.

also : switch powerpc tests to trusty,
as they seem to fail on xenial environment.

6d65c2a17c ensure all secret consumers read in 64-bit 
so that secret can be transformed into a "blob of bytes"
thus being compatible with any endianess
