All,
  Where are the SSE instructions defined? Specifically, I
cannot find the def for ADDSDrr.

Hi Aran,

Where are the SSE instructions defined? Specifically, I
cannot find the def for ADDSDrr.

take a look at X86InstrSSE.td, lines 1,472 and 1,425 ff.
ADDSDrr is defined as part of a multiclass [1] record, that's why simple
grep'ing doesn't work. :slight_smile:
