C++ AMP: view generated HLSL code

Question

Hi,

Is there any way to see the generated HLSL code from a C++ AMP kernel ?

Best regards, Arnaud.

Answer 1

Hi Arnaud

Unfortunately we don’t offer the capability to view the HLSL code.

To be honest, the code we generate is very optimized, and is more like assembly code in both the level it describes things, names it uses and its structure. It is nowhere near the HLSL code that a human could write and indeed not something they could read without a lot of effort. It also is an implementation detail that we do not wish to expose.

Was it just curiosity or did you have a specific scenario that you think the code would enable? If you had access to the HLSL bytecode, would that cater for your scenario?

Cheers
Daniel

Hi Daniel,

It was for learning purposes, in order to understand better how to write efficient kernels. To make a parallel with .asm listings, after studying them, you write better code.

Thanks for your reply, Arnaud.

It's possible to see kernel disassembly, it's not HLSL.  See Amit's reply in this thread:
