Overview

    This extension provides a subset of the functionality of that provided
    by the cl_khr_fp64 extension.  When enabled, the compiler recognizes
    the double scalar and vector types, compiles expressions involving
    those types, and accepts calls to all builtin functions enabled by
    the cl_khr_fp64 extension.  However, this extension does not guarantee
    that all cl_khr_fp64 built in functions are implemented and does not
    guarantee that the built in functions that have been implemented would
    be considered conformant to the cl_khr_fp64 extension.

Additions to Chapter 9 of the OpenCL 1.0 Specification

    A new section is added to chapter 9 which replicates the content of
    section 9.3 with cl_khr_fp64 replaced with cl_amd_fp64 everywhere
    it appears, a statment in the introduction that not all built in
    functions may be implemented, and that the set of implemented
    functions will differ depending on the AMD Stream Release version,
    and the omission of subsections corresponding to 9.3.8 IEEE754
    compliance and 9.3.9 Relative Error as ULPs.
