2012-05-01ARM: allow vanilla expressions for movw/movt.Jim Grosbach
Expressions for movw/movt don't always have an :upper16: or :lower16: on them and that's ok. When they don't, it's just a plain [0-65536] immediate result, effectively the same as a :lower16: variant kind. rdar://10550147 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155941 91177308-0d34-0410-b5e6-96231b3b80d8

2012-04-30ARM: Diagnostics for out of range fixups.Jim Grosbach
Replace some assert() calls w/ actual diagnostics. In a perfect world, there'd be range checks on these values long before things ever reached this code. For now, though, issuing a better-late-than-never diagnostic is still a big improvement over assert(). rdar://11347287 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155851 91177308-0d34-0410-b5e6-96231b3b80d8
2012-04-30Fix address calculation error from r155744.Jakob Stoklund Olesen
This was exposed by SingleSource/UnitTests/Vector/constpool.c. The computed size of a basic block isn't always a multiple of its known alignment, and that can introduce extra alignment padding after the block. <rdar://problem/11347135> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155845 91177308-0d34-0410-b5e6-96231b3b80d8

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.

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
