Detailed Description

AMDGPU target specific 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.
