* util: rename PIPE_ARCH_*_ENDIAN to UTIL_ARCH_*_ENDIANDylan Baker2019-11-051-11/+11

* util/u_endian: set PIPE_ARCH_*_ENDIAN to 1Dylan Baker2019-11-051-10/+10
| | | | | | | | | | | | This will allow it to be used as a drop in replacement for _mesa_little_endian in a number of cases. v2: - Always define PIPE_ARCH_LITTLE_ENDIAN and PIPE_ARCH_BIG_ENDIAN, define the one that reflects the host system to 1 and the other to 0 - replace all uses of #ifdef, #ifndef, and #if defined() with #if and #if ! with PIPE_ARCH_*_ENDIAN Reviewed-by: Eric Engestrom <[email protected]>
* llvmpipe: fix arguments order given to vec_andcOded Gabbay2016-01-171-0/+6
| | | | | | | | | | | | | | | | This patch fixes a classic "confuse the enemy" bug. _mm_andnot_si128 (SSE) and vec_andc (VMX) do the same operation, but the arguments are opposite. _mm_andnot_si128 performs "r = (~a) & b" while vec_andc performs "r = a & (~b)" To make sure this error won't return in another place, I added a wrapper function, vec_andnot_si128, in u_pwr8.h, which makes the swap inside.

* llvmpipe: add POWER8 portability file - u_pwr8.hOded Gabbay2016-01-061-0/+310
This file provides a portability layer that will make it easier to convert SSE-based functions to VMX/VSX-based functions. All the functions implemented in this file are prefixed using "vec_". Therefore, when converting from SSE-based function, one needs to simply replace the "_mm_" prefix of the SSE function being called to "vec_". Having said that, not all functions could be converted as such, due to the differences between the architectures. So, when doing such conversion hurt the performance, I preferred to implement a more ad-hoc solution. For example, converting the _mm_shuffle_epi32 needed to be done using ad-hoc masks instead of a generic function. All the functions in this file support both little-endian and big-endian but currently the file is build only on POWER8 LE machine. All of the functions are implemented using the Altivec/VMX intrinsics, except one where I needed to use inline assembly (due to missing intrinsic). v2: - Use vec_vgbbd instead of __builtin_vec_vgbbd - Add an aligned load function - Don't use typeof() - Make file build only on POWER8 LE machine Signed-off-by: Oded Gabbay <[email protected]> Reviewed-by: Roland Scheidegger <[email protected]>
