New Revision: 244372
URL: http://llvm.org/viewvc/llvm-project?rev=244372&view=rev
Log:
AMDGPU: Add pass to lower OpenCL image and sampler arguments.
The pass adds new kernel arguments for image attributes, and
resolves calls to dummy attribute and resource id getter functions.

+/// This pass resolves calls to OpenCL image attribute, image resource ID and
+/// sampler resource ID getter functions.
+///
+/// Image attributes (size and format) are expected to be passed to the kernel
+/// as kernel arguments immediately following the image argument itself,
+/// therefore this pass adds image size and format arguments to the kernel
+/// functions in the module. The kernel functions with image arguments are
+/// re-created using the new signature. The new arguments are added to the
+/// kernel metadata with kernel_arg_type set to "image_size" or "image_format".
+/// Note: this pass may invalidate pointers to functions.
+///
+/// Resource IDs of read-only images, write-only images and samplers are
+/// defined to be their index among the kernel arguments of the same
+/// type and access qualifier.
