We don't have v_permlane64_b32 yet, but we can still optimize it using shared vgprs. Using the DPP16 row mask, we can even avoid writing exec. With v0 input/output and v24/v25 as shared vgprs, this results in: v_mov_b32_dpp v24, v0 quad_perm:[0,1,2,3] row_mask:0x3 bank_mask:0xf v_mov_b32_dpp v25, v0 quad_perm:[0,1,2,3] row_mask:0xc bank_mask:0xf v_mov_b32_dpp v0, v24 quad_perm:[0,1,2,3] row_mask:0xc bank_mask:0xf v_mov_b32_dpp v0, v25 quad_perm:[0,1,2,3] row_mask:0x3 bank_mask:0xf Reviewed-by: Daniel Schürmann <daniel@schuermann.dev> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/36390> |
