2009-08-30Fix PR4748: don't fold gep(bitcast(x)) into bitcast(gep) when x Chris Lattner
is itself a bitcast. Since we have gep(bitcast(bitcast(y))) in this case, just wait for the two bitcasts to get zapped. This prevents instcombine from confusing some aliasing stuff, and allows it to directly eliminate the load in the testcase. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80508 91177308-0d34-0410-b5e6-96231b3b80d8

implementation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80493 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-30give instcombine a custom IRBuilder that adds new instructions to theChris Lattner
workslist and is set to insert new instructions before the current one. Convert a bunch of stuff that used to call InsertNewInstBefore over to use it, greatly simplifying code and making it more natural. There is still a lot more to go, but this is a good start. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80492 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-30add a new InstCombineWorklist::AddValue method that works evenChris Lattner
if the operand is not an instruction. Simplify most uses of AddOperandsToWorkList to use AddValue and inline it into the one remaining callsite. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80488 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-30move AddUsersToWorkList to the worklist processing class, make theChris Lattner
argument stronger typed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80487 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-30rename AddUsesToWorkList -> AddOperandsToWorkList. The Chris Lattner
former looks too much like AddUsersToWorkList and keeps confusing me. Remove AddSoonDeadInstToWorklist and change its two callers to do the same thing in a simpler way. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80486 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-30llvm-mc: MCStreamer cleanups. - Remove EmitLocalSymbol, this is unsupported ↵Daniel Dunbar
for now. - Switch Emit{CommonSymbol,Zerofill} to take alignment in bytes (for consistency). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80484 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-30inline the trivial AddToWorkList/RemoveFromWorkList methodsChris Lattner
into their callers. simplify ReplaceInstUsesWith. Make EraseInstFromFunction only add operands to the worklist if there aren't too many of them (this was a scalability win for crazy programs that was only infrequently enforced). Switch more code to using EraseInstFromFunction instead of duplicating it inline. Change some fcmp/icmp optimizations to modify fcmp/icmp in place instead of creating a new one and deleting the old one just to change the predicate. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80483 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-29- Add target lowering methods to get the preferred format for the FDE and LSDABill Wendling
encodings. - Make some of the values emitted by the FDEs dependent upon the pointer size. This is in line with how GCC does things. And it has the benefit of working for Darwin in 64-bit mode now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80428 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-29PR4795: Remove EEVT::isFP, isInt and isVec types used by TableGen's typeBob Wilson
inferencing. As far as I can tell, these are equivalent to the existing MVT::fAny, iAny and vAny types, and having both of them makes it harder to reason about and modify the type inferencing code. The specific problem in PR4795 occurs when updating a vAny type to be fAny or iAny, or vice versa. Both iAny and fAny include vector types -- they intersect with the set of types represented by vAny. When merging them, choose fAny/iAny to represent the intersection. This is not perfect, since fAny/iAny also include scalar types, but it is good enough for TableGen's type inferencing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80423 91177308-0d34-0410-b5e6-96231b3b80d8
