2013-02-05Convert to storing the attribute's internals as enums, integers, and strings.Bill Wendling
The stuff we're handing are all enums (Attribute::AttrKind), integers and strings. Don't convert them to Constants, which is an unnecessary step here. The rest of the changes are mostly mechanical. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174456 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-05[mips] Do not use function CC_MipsN_VarArg unless the function being analyzedAkira Hatanaka
is a vararg function. The original code was examining flag OutputArg::IsFixed to determine whether CC_MipsN_VarArg or CC_MipsN should be called.

2013-02-05Reapply r174343, with a fix for a scary DAG combine bug where it failed to ↵Owen Anderson
differentiate between the alignment of the base point of a load, and the overall alignment of the load. This caused infinite loops in DAG combine with the original application of this patch. ORIGINAL COMMIT LOG: When the target-independent DAGCombiner inferred a higher alignment for a load, it would replace the load with one with the higher alignment. However, it did not place the new load in the worklist, which prevented later DAG combines in the same phase (for example, target-specific combines) from ever seeing it. This patch corrects that oversight, and updates some tests whose output changed due to slightly different DAGCombine outputs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174431 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-05[MC] Bundle alignment: Invalidate relaxed fragmentsDerek Schuff
Currently, when a fragment is relaxed, its size is modified, but its offset is not (it gets laid out as a side effect of checking whether it needs relaxation), then all subsequent fragments are invalidated because their offsets need to change. When bundling is enabled, relaxed fragments need to get laid out again, because the increase in size may push it over a bundle boundary. So instead of only invalidating subsequent fragments, also invalidate the fragment that gets relaxed, which causes it to get laid out again. This patch also fixes some trailing whitespace and fixes the bundling-related debug output of MCFragments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174401 91177308-0d34-0410-b5e6-96231b3b80d8
2013-02-05Don't use MRI liveouts in R600.Jakob Stoklund Olesen
Something very strange is going on with the output registers in this target. Its ISelLowering code is inserting dangling CopyToReg nodes, hoping that those physregs won't get clobbered before the RETURN. This patch adds the output registers as implicit uses on RETURN instructions in the custom emission pass. I'd much prefer to have those CopyToReg nodes glued to the RETURNs, but I don't see how. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174400 91177308-0d34-0410-b5e6-96231b3b80d8

2013-02-05R600: improve inputs/interpolation handlingTom Stellard
Use one intrinsic for all sorts of interpolation. Use two separate unexpanded instructions to represent INTERP_XY and _ZW - this will allow to eliminate one part if it's not used. Track liveness of special interpolation regs instead of reserving them - this will allow to reuse those regs, lowering reg pressure.

2013-02-05Loop Vectorizer: Handle pointer stores/loads in getWidestType()Arnold Schwaighofer
In the loop vectorizer cost model, we used to ignore stores/loads of a pointer type when computing the widest type within a loop. This meant that if we had only stores/loads of pointers in a loop we would return a widest type of 8bits (instead of 32 or 64 bit) and therefore a vector factor that was too big. Now, if we see a consecutive store/load of pointers we use the size of a pointer (from data layout). This problem occured in SingleSource/Benchmarks/Shootout-C++/hash.cpp (reduced test case is the first test in vector_ptr_load_store.ll). radar://13139343 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@174377 91177308-0d34-0410-b5e6-96231b3b80d8
