## ◆ MAYBE_UNCONST_CAST

#define MAYBE_UNCONST_CAST | ( |  | T,
|  |  | x
| ) |  | (x)

## ◆ M128_CAST

#define M128_CAST | ( |  | x | ) | ((__m128i *)(void *)(x))

Clang workaround.

Clang issues spurious alignment warnings

See also

## Function Documentation

## ◆ AdvancedProcessBlocks128_6x1_NEON()

template<typename F1 , typename F6 , typename W >

size_t AdvancedProcessBlocks128_6x1_NEON | ( | F1 | func1,
|  | F6 | func6,
|  | const W * | subKeys,
|  | size_t | rounds,
|  | const byte * | inBlocks,
|  | const byte * | xorBlocks,
|  | byte * | outBlocks,
|  | size_t | length,
|  | word32 | flags
| ) |  |
| inline

AdvancedProcessBlocks for 1 and 6 blocks.

Template Parameters

  F1 | function to process 1 128-bit block
  F6 | function to process 6 128-bit blocks
  W | word type of the subkey table

AdvancedProcessBlocks128_6x1_NEON processes 6 and 2 NEON SIMD words at a time.

The subkey type is usually word32 or word64. F1 and F6 must use the same word type.

Definition at line 100 of file adv_simd.h.

## ◆ AdvancedProcessBlocks128_4x1_NEON()

template<typename F1 , typename F4 , typename W >

size_t AdvancedProcessBlocks128_4x1_NEON | ( | F1 | func1,
|  | F4 | func4,

|  | byte * | outBlocks,
|  | size_t | length,
|  | word32 | flags
| ) |  |
| inline

AdvancedProcessBlocks for 1 and 4 blocks.

Template Parameters

  F1 | function to process 1 128-bit block
  F4 | function to process 4 128-bit blocks
  W | word type of the subkey table

AdvancedProcessBlocks128_4x1_NEON processes 4 and 1 NEON SIMD words at a time.

The subkey type is usually word32 or word64. V is the vector type and it is usually uint32x4_t or uint32x4_t. F1, F4, and W must use the same word and vector type.

Definition at line 254 of file adv_simd.h.

## ◆ AdvancedProcessBlocks128_6x2_NEON()

template<typename F2 , typename F6 , typename W >

size_t AdvancedProcessBlocks128_6x2_NEON | ( | F2 | func2,

| ) |  |
| inline

AdvancedProcessBlocks for 2 and 6 blocks.

Template Parameters

  F2 | function to process 2 128-bit blocks
  F6 | function to process 6 128-bit blocks
  W | word type of the subkey table

AdvancedProcessBlocks128_6x2_NEON processes 6 and 2 NEON SIMD words at a time. For a single block the template uses F2 with a zero block.

The subkey type is usually word32 or word64. F2 and F6 must use the same word type.
