/// \file |
-/// This file declares the InstX8632 and OperandX8632 classes and |
-/// their subclasses. This represents the machine instructions and |
-/// operands used for x86-32 code selection. |
+/// This file used to house all the X8632 instructions. Subzero has been |
+/// modified to use templates for X86 instructions, so all those definitions are |
+/// are in IceInstX86Base.h |
+/// |
+/// When interacting with the X8632 target (which should only happen in the |
+/// X8632 TargetLowering) clients have should use the Ice::X8632::Traits::Insts |
+/// traits, which hides all the template verboseness behind a type alias. |
+/// |
+/// For example, to create an X8632 MOV Instruction, clients should do |
+/// |
+/// ::Ice::X8632::Traits::Insts::Mov::create |
+/// |
+/// In the future, this file might be used to declare X8632 specific |
+/// instructions (e.g., FLD, and FSTP.) |

-/// |
