How do you view the assembly code of your hlsl code?

I am using visual studio 2017 and an nvidia graphics card.

I tried looking in the visual studio graphics analyzer ("debug - graphics - start graphics debugging" from visual studio opens that) but where I would expect it to be it says "Enable GPU disassembly via View->Options->Graphics Diagnostics->Enable gather of GPU Disassembly.
The vsglog must be re-opened for this change to take effect."

However that isnt an option you can select.

I would actually prefer a way to view the asm without having to capture a frame, as my program doesnt do well in the visual studio graphics analyzer

When I try to playback a captured frame I get "An error has occured. Playback of your application may be incomplete (HRESULT = 0x00630000)"

However I am able to play back captured frames of the microsoft samples, but I am still not able to see asm code with them.

Any assembly that can help me optimise my hlsl code, I dont mind which.

I believe its described here - https://msdn.microsoft.com/en-us/library/windows/desktop/hh447232(v=vs.85).aspx

Thankyou I will check it out.

Is this peoples prefered way of viewing the hlsl assembly code ?

Thankyou everyone - the FXC.exe worked perfectly to make the assembly code.

Previously I had just been using the D3DCompileFromFile function to compile my hlsl.

Be careful about optimizing the directx bytecode. Optimization to it usually does not translate well to the final uCode of vendors and may even give the driver compiler a harder time.
