Reference
AMDGPU / GFX ISA
Description
Load 4-component formatted data from a buffer surface, convert the data to packed 16 bit integral or floating point format, then store the result into a vector register. The instruction specifies the data format of the surface, overriding the resource descriptor.
Example
tbuffer_load_d16_format_xyzw v[4:5], off, ttmp[4:7], 61, format:18 offset:4095A real instruction accepted by the LLVM assembler, taken verbatim from LLVM's own AMDGPU MC test suite (gfx11). Not from an AMD document, and not authored here.
