Currently supported LLVM MTBUF syntax is shown below. It is not compatible with SP3.
op dst, addr, rsrc, FORMAT, soffset
This change adds support for SP3 syntax:
op dst, addr, rsrc, soffset SP3FORMAT
In addition to being compatible with SP3, this syntax allows using symbolic names for data, numeric and unified formats. Below is a list of added syntax variants.
format:<expression>
format:[<numeric-format-name>,<data-format-name>]
format:[<data-format-name>,<numeric-format-name>]
format:[<data-format-name>]
format:[<numeric-format-name>]
format:[<unified-format-name>]
The last syntax variant is supported for GFX10 only.
