What’s with all the asm? • We’ll show a lot of asm in this section to introduce the virtual machine • Later sections will focus on HLSL since that is what we expect most developers will prefer to use • Familiarity with the asm is useful, however • Also, the currently-available HLSL compiler does not support flow-control, though that is coming in a future revision. Microsoft will discuss more details of this in their event tomorrow.
