// This file isn't part of a standard HACL source tree.

// It is required for compatibility with universal2 macOS builds. The code in
|
|
// Hacl_Hash_Blake2b_Simd256.c *will* compile on macOS x86_64, but *won't*
|
|
// compile on ARM64. However, because universal2 builds are compiled in a
|
|
// single pass, autoconf detects that the required compiler features *are*
|
|
// available, and tries to compile this file, which then fails because of the
|
|
// lack of support on ARM64.
|
|
//
|
|
// To compensate for this, autoconf will include *this* file instead of
|
|
// Hacl_Hash_Blake2b_Simd256.c when compiling for universal. This allows the
|
|
// underlying source code of HACL to remain unmodified.
