2012-02-29Add an analyzeVirtReg() function.Jakob Stoklund Olesen
This function does more or less the same as MI::readsWritesVirtualRegister(), but it supports bundles as well. It also determines if any constraint requires reading and writing operands to use the same register. Most clients want to know. Use the more modern MO.readsReg() instead of trying to sort out undefs and partial redefines. Stop supporting the extra full <imp-def> operand as an alternative to <def,undef> sub-register defines. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151690 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-28LegalizeIntegerTypes: Reenable the large shift with small amount optimization.Benjamin Kramer
To avoid problems with zero shifts when getting the bits that move between words we use a trick: first shift the by amount-1, then do another shift by one. When amount is 0 (and size 32) we first shift by 31, then by one, instead of by 32. Also fix a latent bug that emitted the low and high words in the wrong order when shifting right. Fixes PR12113. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151637 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-28Fix a bug in the code that builds SDNodes from vector GEPs.Nadav Rotem
When the GEP index is a vector of pointers, the code that calculated the size of the element started from the vector type, and not the contained pointer type. As a result, instead of looking at the data element pointed by the vector, this code used the size of the vector. This works for 32bit members (on 32bit systems), but not for other types. Added code to peel the vector type and added a test. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151626 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-28Some ARM implementaions, e.g. A-series, does return stack prediction. That is,Evan Cheng
the processor keeps a return addresses stack (RAS) which stores the address and the instruction execution state of the instruction after a function-call type branch instruction. Calling a "noreturn" function with normal call instructions (e.g. bl) can corrupt RAS and causes 100% return misprediction so LLVM should use a unconditional branch instead. i.e. mov lr, pc b _foo The "mov lr, pc" is issued in order to get proper backtrace. rdar://8979299 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151623 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-28Enable ARM base pointer when calling functions with large arguments.Jakob Stoklund Olesen
When an outgoing call takes more than 2k of arguments on the stack, we don't allocate that call frame in the prolog, but adjust the stack pointer immediately before the call instead. This causes problems with the emergency spill slot because PEI can't track stack pointer adjustments on the second pass, and if the outgoing arguments are too big, SP can't be used to reach the emergency spill slot at all. Work around these problems by ensuring there is a base or frame pointer that can be used to access the emergency spill slot. <rdar://problem/10917166> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@151604 91177308-0d34-0410-b5e6-96231b3b80d8
