Hi, Simon!
Interesting work! Except OpenCL specifics, it looks somewhat similar
to LLVM C backend, if I understand correctly. Have you used it or
wrote your own code generator completely from scratch?
Thanks,

>> That being said, AMD OpenCL is not a target of LLVM. AMD uses LLVM for its optimizer and code generation paths for the OpenCL compiler.

>> Hi all!
>>
>> I'm getting starting with LLVM, and I'm creating a new cross-platform programming language LLVM-based with a Standard Library POSIX-based. The language has sintatic sugar of Object Pascal and Ruby.
>>
>> My doubt is if LLVM is compatible with AMD (e.g. Fusion), allowing so that my StdLib can be used to create Games, in future...
>> [Villmow, Micah] AMD uses LLVM for its OpenCL compilers which run on Fusion parts and LLVM itself can generate X86 code. However, there currently is no way to target the X86 GPU?s directly. You might want to look at the Gallium3D project(Linux only) for a way to do this.
