-; Module Name:
-;
-; ProcessorAsms.Asm
-;
-; Abstract:
-; This is separated from processor.c to allow this functions to be built with /O1
-;
-; Notes:
-; - Masm uses "This", "ebx", etc as a directive.
-; - H2INC is still not embedded in our build process so I translated the struc manually.
-; - Unreferenced variables/arguments (This, NewBsp, NewStack) were causing compile errors and
-; did not know of "pragma" mechanism in MASM and I did not want to reduce the warning level.
-; Instead, I did a dummy referenced.
