Fun x86 encoding tricks: when adding an immediate value of 128, use a SUB instruction instead of an ADD, because -128 can be encoded in an 8-bit signed immediate field, while +128 can't be. This avoids the need for a 32-bit immediate field in this case. A similar optimization applies to 64-bit adds with 0x80000000, with the 32-bit signed immediate field. To support this, teach tablegen how to handle 64-bit constants. llvm-svn: 57663 2008-10-17 03:33:43 +02:00			`// RUN: tblgen %s \| grep -- 4294901760`
