2012-05-04Initialize SparcInstrInfo before SparcTargetLowering.Jakob Stoklund Olesen
The TargetLowering construction needs to use a valid TargetRegisterInfo instance. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156146 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-04Add a SuperRegClassIterator class.Jakob Stoklund Olesen
This iterator class provides a more abstract interface to the (Idx, Mask) lists of super-registers for a register class. The layout of the tables shouldn't be exposed to clients. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156144 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-03Use a shared implementation of getMatchingSuperRegClass().Jakob Stoklund Olesen
TargetRegisterClass now gives access to the necessary tables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156122 91177308-0d34-0410-b5e6-96231b3b80d8
2012-05-03Fix issues with the ARM bl and blx thumb instructions and the J1 and J2 bitsKevin Enderby

2012-05-03Added TargetRegisterInfo::getAllocatableClass.Andrew Trick
The ensures that virtual registers always belong to an allocatable class. If your target attempts to create a vreg for an operand that has no allocatable register subclass, you will crash quickly. This ensures that targets define register classes as intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@156046 91177308-0d34-0410-b5e6-96231b3b80d8

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
2012-05-01This patch marks the X86 floating point stack registers ST0-ST7 as reservedPreston Gurd
in order to avoid assertion failures in the register scavenger. The assertion failures were “Bad machine code: Using an undefined physical register” and “Bad machine code: MBB exits via unconditional fall-through but its successor differs from its CFG successor!”. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155930 91177308-0d34-0410-b5e6-96231b3b80d8

2012-05-01Change the PassManager from a reference to a pointer.Bill Wendling
The TargetPassManager's default constructor wants to initialize the PassManager to 'null'. But it's illegal to bind a null reference to a null l-value. Make the ivar a pointer instead. PR12468 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@155902 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

This was exposed by SingleSource/UnitTests/Vector/constpool.c.

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
