Summary: These new image intrinsics contain the texture type as part of their name and have each component of the address/coordinate as individual parameters. This is a preparatory step for implementing the A16 feature, where coordinates are passed as half-floats or -ints, but the Z compare value and texel offsets are still full dwords, making it difficult or impossible to distinguish between A16 on or off in the old-style intrinsics. Additionally, these intrinsics pass the 'texfailpolicy' and 'cachectrl' as i32 bit fields to reduce operand clutter and allow for future extensibility. v2: - gather4 supports 2darray images - fix a bug with 1D images on SI Change-Id: I099f309e0a394082a5901ea196c3967afb867f04 Reviewers: arsenm, rampitec, b-sumner Subscribers: kzhuravl, wdng, yaxunl, dstuttard, tpr, llvm-commits, t-tye Differential Revision: https://reviews.llvm.org/D44939 llvm-svn: 329166
