Function Documentation

cpu_bswap16()

static uint16_t cpu_bswap16 ( uint16_t  x )

inlinestatic

Swap the upper and lower bytes of a 2-byte value.

The __builtin_bswap16() function that GCC emits does not use the swap.b instruction.

Parameters

x	Value to be swapped.

Returns

Swapped value.

cpu_bswap32()

static uint32_t cpu_bswap32 ( uint32_t  x )

inlinestatic

Swap the upper and lower 2-bytes of a 4-byte value.

The __builtin_bswap32() function that GCC emits does not use the swap.w instruction.

Parameters

x	Value to be swapped.

Returns

Swapped value.
