From: Iago Toral Quiroga Date: Thu, 21 Jan 2016 09:46:39 +0000 (+0100) Subject: glsl/lower_instructions: fix regression in dldexp_to_arith X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ab0c7c0829d2e5ac69ca51a8981f3b1b88bd8d01;p=mesa.git glsl/lower_instructions: fix regression in dldexp_to_arith The commit b4e198f47f842 changed the offset and bits parameters of the bitfield insert operation from scalars to vectors. However, the lowering of ldexp on doubles operates on each vector component and emits scalar code (since it has to deal with the lower and upper 32-bit chunks of each double component), so it needs its bits and offset parameters to be scalars.
