c74be3f6de [lib] Validate buffers when ZSTD_c_stable{In,Out}Buffer is set 
Adds the validation of the input/output buffers only. They are still
unused.

Merge pull request #2356 from bsdimp/neon 
aarch64: use __ARM_NEON instead of __aarch64__ to control use of neon

43c0054405 aarch64: use __ARM_NEON instead of __aarch64__ to control use of neon 
There are compilation environments in aarch64 where NEON isn't
available. While these environments could define ZSTD_NO_INTRINSICS,
it's more fail-safe to use the more specific symbol to know if NEON
extensions are available.

__ARM_NEON is the proper symbol, defined in ARM C Language Extensions
Release 2.1 (https://developer.arm.com/documentation/ihi0053/d/). Some
sources suggest __ARM_NEON__, but that's the obsolete spelling from
prior versions of the standard.

caecd8c211 Allow user to override ASAN/MSAN detection 
Rename ADDRESS_SANITIZER -> ZSTD_ADDRESS_SANITIZER and same for
MEMORY_SANITIZER. Also set it to 0/1 instead of checking for defined.
This allows the user to override ASAN/MSAN detection for platforms that
don't support it.

79ded1b4a9 [lib] Add ZSTD_NO_UNUSED_FUNCTIONS macro to hide unused functions 
The unused function definitions are hidden behind a
`#ifndef ZSTD_NO_UNUSED_FUNCTIONS` check.

Initially hiding all functions which are unused and take up more than
2KB of stack space, because these will show up as warnings in the
Linux Kernel build system.

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