* Fix PR10475Michael Liao2013-03-011-1/+1
| | | | | | | | | | | | | | | | - ISD::SHL/SRL/SRA must have either both scalar or both vector operands but TLI.getShiftAmountTy() so far only return scalar type. As a result, backend logic assuming that breaks. - Rename the original TLI.getShiftAmountTy() to TLI.getScalarShiftAmountTy() and re-define TLI.getShiftAmountTy() to return target-specificed scalar type or the same vector type as the 1st operand. - Fix most TICG logic assuming TLI.getShiftAmountTy() a simple scalar type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@176364 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | 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

* Eliminate target hook IsEligibleForTailCallOptimization.Evan Cheng2010-01-271-1/+1
| | | | | | | | | | Target independent isel should always pass along the "tail call" property. Change target hook LowerCall's parameter "isTailCall" into a refernce. If the target decides it's impossible to honor the tail call request, it should set isTailCall to false to make target independent isel happy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@94626 91177308-0d34-0410-b5e6-96231b3b80d8

* Major calling convention code refactoring.Dan Gohman2009-08-051-11/+43
| | | | | | | | | | | | | | | | | | | | Instead of awkwardly encoding calling-convention information with ISD::CALL, ISD::FORMAL_ARGUMENTS, ISD::RET, and ISD::ARG_FLAGS nodes, TargetLowering provides three virtual functions for targets to override: LowerFormalArguments, LowerCall, and LowerRet, which replace the custom lowering done on the special nodes. They provide the same information, but in a more immediately usable format. This also reworks much of the target-independent tail call logic. The decision of whether or not to perform a tail call is now cleanly split between target-independent portions, and the target dependent portion in IsEligibleForTailCallOptimization. This also synchronizes all in-tree targets, to help enable future refactoring and feature work. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@78142 91177308-0d34-0410-b5e6-96231b3b80d8
