Macro Definition Documentation

VEC128_MASK

#define VEC128_MASK	(		input,
			mask
	)		((v4fp_t)((v4sfx_t)input & mask))

Apply a elementwise mask to a 128-bit packed single precision FP vector.

The mask is a vector of either 0s or -1s (all 1s). Entries that are have a mask of 0 are zeroed out.

LLVM is smart enough to turn this into a SELECT instruction, rather than a bitwise mask!

Parameters

input	A v4fp_t vector.
mask	A v4sfx_t vector of either 0s or -1s.

VEC256_MASK

#define VEC256_MASK	(		input,
			mask
	)		((v8fp_t)((v8sfx_t)input & mask))

Same as VEC128_MASK, but for 256-bit vectors.

Parameters

input	A v4fp_t vector.
mask	A v4sfx_t vector of either 0s or -1s.
