2012-04-30Fix fastcc structure return with fast-isel on x86-32Derek Schuff
On x86-32, structure return via sret lets the callee pop the hidden pointer argument off the stack, which the caller then re-pushes. However if the calling convention is fastcc, then a register is used instead, and the caller should not adjust the stack. This is implemented with a check of IsTailCallConvention X86TargetLowering::LowerCall but is now checked properly in X86FastISel::DoSelectCall. (this time, actually commit what was reviewed!) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155825 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-30Don't introduce illegal types when creating vmull operations. <rdar://11324364>Bob Wilson
ARM BUILD_VECTORs created after type legalization cannot use i8 or i16 operands, since those types are not legal. Instead use i32 operands, which will be implicitly truncated by the BUILD_VECTOR to match the element type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155824 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-30Second attempt at PR12573:Bill Wendling
Allow the "SplitCriticalEdge" function to split the edge to a landing pad. If the pass is *sure* that it thinks it knows what it's doing, then it may go ahead and specify that the landing pad can have its critical edge split. The loop unswitch pass is one of these passes. It will split the critical edges of all edges coming from a loop to a landing pad not within the loop. Doing so will retain important loop analysis information, such as loop simplify. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155817 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-27Track worst case alignment padding more accurately.Jakob Stoklund Olesen
Previously, ARMConstantIslandPass would conservatively compute the address of an aligned basic block as: RoundUpToAlignment(Offset + UnknownPadding) This worked fine for the layout algorithm itself, but it could fool the verify() function because it accounts for alignment padding twice: Once when adding the worst case UnknownPadding, and again by rounding up the fictional block offset. This meant that when optimizeThumb2Instructions would shrink an instruction, the conservative distance estimate could grow. That shouldn't be possible since the woorst case alignment padding wss already included. This patch drops the use of RoundUpToAlignment, and depends only on worst case padding to compute conservative block offsets. This has the weird effect that the computed offset for an aligned block may not be aligned. The important difference is that shrinking an instruction can never cause the estimated distance between two instructions to grow. The estimated distance is always larger than the real distance that only the assembler knows. <rdar://problem/11339352> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155744 91177308-0d34-0410-b5e6-96231b3b80d8

Target specific types should not be vectorized. As a practical matter, these types are already register matched (at least in the x86 case), and codegen does not always work correctly (at least in the ppc case, and this is not worth fixing because ppc_fp128 is currently broken and will probably go away soon). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155729 91177308-0d34-0410-b5e6-96231b3b80d8
