vmx: add helper functions
This patch adds the following helper functions for reuse of code,
hiding BE/LE differences and maintainability.
All of the functions were defined as static force_inline.
Names were copied from pixman-sse2.c so conversion of fast-paths between
sse2 and vmx would be easier from now on. Therefore, I tried to keep the
input/output of the functions to be as close as possible to the sse2
definitions.
The functions are:
- load_128_aligned : load 128-bit from a 16-byte aligned memory
address into a vector
- load_128_unaligned : load 128-bit from memory into a vector,
without guarantee of alignment for the
source pointer
- save_128_aligned : save 128-bit vector into a 16-byte aligned
memory address
- create_mask_16_128 : take a 16-bit value and fill with it
a new vector
- create_mask_1x32_128 : take a 32-bit pointer and fill a new
vector with the 32-bit value from that pointer
- create_mask_32_128 : take a 32-bit value and fill with it
a new vector
- unpack_32_1x128 : unpack 32-bit value into a vector
- unpacklo_128_16x8 : unpack the eight low 8-bit values of a vector
- unpackhi_128_16x8 : unpack the eight high 8-bit values of a vector
- unpacklo_128_8x16 : unpack the four low 16-bit values of a vector
- unpackhi_128_8x16 : unpack the four high 16-bit values of a vector
- unpack_128_2x128 : unpack the eight low 8-bit values of a vector
into one vector and the eight high 8-bit
values into another vector
- unpack_128_2x128_16 : unpack the four low 16-bit values of a vector
into one vector and the four high 16-bit
values into another vector
- unpack_565_to_8888 : unpack an RGB_565 vector to 8888 vector
- pack_1x128_32 : pack a vector and return the LSB 32-bit of it
- pack_2x128_128 : pack two vectors into one and return it
- negate_2x128 : xor two vectors with mask_00ff (separately)
- is_opaque : returns whether all the pixels contained in
the vector are opaque
- is_zero : returns whether the vector equals 0
- is_transparent : returns whether all the pixels
contained in the vector are transparent
- expand_pixel_8_1x128 : expand an 8-bit pixel into lower 8 bytes of a
vector
- expand_alpha_1x128 : expand alpha from vector and return the new
vector
- expand_alpha_2x128 : expand alpha from one vector and another alpha
from a second vector
- expand_alpha_rev_2x128 : expand a reversed alpha from one vector and
another reversed alpha from a second vector
- pix_multiply_2x128 : do pix_multiply for two vectors (separately)
- over_2x128 : perform over op. on two vectors
- in_over_2x128 : perform in-over op. on two vectors
v2: removed expand_pixel_32_1x128 as it was not used by any function and
its implementation was erroneous
