Benjamin Kramer 162ee5c725 Add a neat little two's complement hack for x86. ... On x86 we can't encode an immediate LHS of a sub directly. If the RHS comes from a XOR with a constant we can fold the negation into the xor and add one to the immediate of the sub. Then we can turn the sub into an add, which can be commuted and encoded efficiently. This code is generated for __builtin_clz and friends. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@136167 91177308-0d34-0410-b5e6-96231b3b80d8		2011-07-26 22:42:13 +00:00
