Assembler Directives
--------------------
.hsa_code_object_version major, minor
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
*major* and *minor* are integers that specify the version of the HSA code
object that will be generated by the assembler. This value will be stored
in an entry of the .note section.
.hsa_code_object_isa [major, minor, stepping, vendor, arch]
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
*major*, *minor*, and *stepping* are all integers that describe the instruction
set architecture (ISA) version of the assembly program.
*vendor* and *arch* are quoted strings. *vendor* should always be equal to
"AMD" and *arch* should always be equal to "AMDGPU".
If no arguments are specified, then the assembler will derive the ISA version,
*vendor*, and *arch* from the value of the -mcpu option that is passed to the
assembler.
ISA version, *vendor*, and *arch* will all be stored in a single entry of the
.note section.
