2013-02-28AArch64: remove post-encoder method from FCMP (immediate) instructions.Tim Northover
The work done by the post-encoder (setting architecturally unused bits to 0 as required) can be done by the existing operand that covers the "#0.0". This removes at least one use of the discouraged PostEncoderMethod uses. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176261 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-28AArch64: be more careful resorting to inefficient addressing for weak vars.Tim Northover
If an otherwise weak var is actually defined in this unit, it can't be undefined at runtime so we can use normal global variable sequences (ADRP/ADD) to access it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176259 91177308-0d34-0410-b5e6-96231b3b80d8

This removes a const_cast hack from PPCRegisterInfo::hasReservedSpillSlot().
