libclc is an open source, BSD licensed implementation of the library
5
requirements of the OpenCL C programming language, as specified by the
6
OpenCL 1.1 Specification. The following sections of the specification
7
impose library requirements:
8

9
  * 6.1: Supported Data Types
10
  * 6.2.3: Explicit Conversions
11
  * 6.2.4.2: Reinterpreting Types Using as_type() and as_typen()
12
  * 6.9: Preprocessor Directives and Macros
13
  * 6.11: Built-in Functions
14
  * 9.3: Double Precision Floating-Point
15
  * 9.4: 64-bit Atomics
16
  * 9.5: Writing to 3D image memory objects
17
  * 9.6: Half Precision Floating-Point
18

19
libclc is intended to be used with the Clang compiler's OpenCL frontend.
20

21
libclc is designed to be portable and extensible. To this end, it provides
22
generic implementations of most library requirements, allowing the target
23
to override the generic implementation at the granularity of individual
24
functions.
25

26
libclc currently only supports the PTX target, but support for more
27
targets is welcome.
