Simon Pilgrim	4003ed2da3	[DAGCombiner] Improve FMA support for interpolation patterns This patch adds support for combining patterns such as (FMUL(FADD(1.0, x), y)) and (FMUL(FSUB(x, 1.0), y)) to their FMA equivalents. This is useful in particular for linear interpolation cases such as (FADD(FMUL(x, t), FMUL(y, FSUB(1.0, t)))) Differential Revision: http://reviews.llvm.org/D13003 llvm-svn: 248210	2015-09-21 20:32:48 +00:00

[DAGCombiner] Improve FMA support for interpolation patterns

This patch adds support for combining patterns such as (FMUL(FADD(1.0, x), y)) and (FMUL(FSUB(x, 1.0), y)) to their FMA equivalents.

This is useful in particular for linear interpolation cases such as (FADD(FMUL(x, t), FMUL(y, FSUB(1.0, t))))

AMDGPU/SI: Select mad patterns to v_mac_f32

The two-address instruction pass will convert these back to v_mad_f32
if necessary.
