e3bda594ae Prefer __builtin_prefetch over inline asm 
Reorder the ifdefs for the PREFETCH macros so that the compiler builtin is
favored over the inline assembly for aarch64.

051232223f optimized histogram 
new version easier to vectorize
leads to smaller code and faster execution
notably at the last recombination stage
(basically, fixed cost per block).

Assembly inspected with godbolt

On my laptop, with `clang` and `-mavx2` :
2K block : 1280 MB/s -> 1550 MB/s
8K block : 1750 MB/s -> 1860 MB/s

Revert "Fix -Wunused-variable under FUZZING_BUILD_MODE..." 2020-07-15 12:42:18 -07:00

23b55d6b3e Fix -Wunused-variable under FUZZING_BUILD_MODE... 
Fuzzing build modes (FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION) doesn't
necessarily imply that assert() is enabled, according to the manual.

When the current do-nothing is expanded under -Wunused-variable (-Wall),
it results in unused variables in some of the FUZZING_BUILD_MODE...
blocks.

This patch extends the do-nothing to avoid the unused variable.

cce0edfdbe Fix unused variable warnings in fuzzing build mode without asserts 
Fix unused vairable warnings when `FUZZING_BUILD_MODE_UNSAFE_FOR_PRODUCTION` is defined but asserts are disabled.

2312b819af [cover] Remove unnecessary mask and dedup hash functions 
* Remove the unnecessary mask, since `ZSTD_hash*()` already ensures
  the output is mod 2^h.
* Dedup the hash functions and use `ZSTD_hash*()` directly.

1047097dad [superblock] Add defensive assert and bounds check 
The bound check condition should always be met because we selected `set_basic` as
our encoding type. But that code is very far away, so assert it is true so if it is
ever false we can catch it, and add a bounds check.

Fixes #2213.
