Detailed Description

AMDGPU target specific variadic MCExpr operations.

Takes in a minimum of 1 argument to be used with an operation. The supported operations are:

(bitwise) or
max

Note: If the 'or'/'max' operations are provided only a single argument, the operation will act as a no-op and simply resolve as the provided argument.
