2008-03-21remove Evan's "ugly hack" that sorta attempted to get Chris Lattner
x86-64 return conventions correct, but was never enabled. We can now do the "right thing" with multiple return values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48635 91177308-0d34-0410-b5e6-96231b3b80d8

ST(0)/ST(1). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48634 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-21Enable support for returning two long-double values in ST(0)/ST(1).Chris Lattner
This allows us to compile fp-stack-2results.ll into: _test: fldz fld1 ret which returns 1 in ST(0) and 0 in ST(1). This is needed for x86-64 _Complex long double. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48632 91177308-0d34-0410-b5e6-96231b3b80d8
2008-03-21Teach masked value is zero about add and sub, and use MVIZ toChris Lattner
simplify things like (X & 4) >> 1 == 2 --> (X & 4) == 4. since it is obvious that the shift doesn't remove any bits. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48631 91177308-0d34-0410-b5e6-96231b3b80d8

2008-03-19Fix live variables issues:Evan Cheng
1. If part of a register is re-defined, an implicit kill and an implicit def are added to denote read / mod / write. However, this should only be necessary if the register is actually read later. This is a performance issue. 2. If a sub-register is being defined, and it doesn't have a previous use, do not add a implicit kill to the last use of a super-register: = EAX, AX<imp-use,kill> ... AX = In this case, EAX is live but AX is killed, this is wrong and will cause the coalescer to do bad things. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@48521 91177308-0d34-0410-b5e6-96231b3b80d8
