| | | | | | | | | an MCSymbol. Make the EH_LABEL MachineInstr hold its label with an MCSymbol instead of ID. Fix a bug in MMI.cpp which would return labels named "Label4" instead of "label4". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98463 91177308-0d34-0410-b5e6-96231b3b80d8
* change EH related stuff (other than EH_LABEL) to use MCSymbolChris Lattner2010-03-141-2/+4
| | | | | | | | | | | | | | | | | | instead of label ID's. This cleans up and regularizes a bunch of code and makes way for future progress. Unfortunately, this pointed out to me that JITDwarfEmitter.cpp is largely copy and paste from DwarfException/MachineModuleInfo and other places. This is very sad and disturbing. :( One major change here is that TidyLandingPads moved from being called in DwarfException::BeginFunction to being called in DwarfException::EndFunction. There should not be any functionality change from doing this, but I'm not an EH expert. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98459 91177308-0d34-0410-b5e6-96231b3b80d8

KILL is not yet used anywhere, it will replace TargetInstrInfo::IMPLICIT_DEF in the places where IMPLICIT_DEF is just used to alter liveness of physical registers. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@83006 91177308-0d34-0410-b5e6-96231b3b80d8

* llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable.Torok Edwin2009-07-141-2/+2
| | | | | | | | | | This adds location info for all llvm_unreachable calls (which is a macro now) in !NDEBUG builds. In NDEBUG builds location info and the message is off (it only prints "UREACHABLE executed"). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75640 91177308-0d34-0410-b5e6-96231b3b80d8
* assert(0) -> LLVM_UNREACHABLE.Torok Edwin2009-07-111-1/+1
| | | | | | | | | | Make llvm_unreachable take an optional string, thus moving the cerr<< out of line. LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for NDEBUG builds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75379 91177308-0d34-0410-b5e6-96231b3b80d8

* Split ISD::LABEL into ISD::DBG_LABEL and ISD::EH_LABEL, eliminatingDan Gohman2008-07-011-1/+2
| | | | | | | | | | | | | | | | | the need for a flavor operand, and add a new SDNode subclass, LabelSDNode, for use with them to eliminate the need for a label id operand. Change instruction selection to let these label nodes through unmodified instead of creating copies of them. Teach the MachineInstr emitter how to emit a MachineInstr directly from an ISD label node. This avoids the need for allocating SDNodes for the label id and flavor value, as well as SDNodes for each of the post-isel label, label id, and label flavor. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@52943 91177308-0d34-0410-b5e6-96231b3b80d8

* Tail call optimization improvements:Arnold Schwaighofer2008-04-301-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Move platform independent code (lowering of possibly overwritten arguments, check for tail call optimization eligibility) from target X86ISelectionLowering.cpp to TargetLowering.h and SelectionDAGISel.cpp. Initial PowerPC tail call implementation: Support ppc32 implemented and tested (passes my tests and test-suite llvm-test). Support ppc64 implemented and half tested (passes my tests). On ppc tail call optimization is performed if caller and callee are fastcc call is a tail call (in tail call position, call followed by ret) no variable argument lists or byval arguments option -tailcallopt is enabled Supported: * non pic tail calls on linux/darwin * module-local tail calls on linux(PIC/GOT)/darwin(PIC) * inter-module tail calls on darwin(PIC) If constraints are not met a normal call will be emitted. A test checking the argument lowering behaviour on x86-64 was added. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50477 91177308-0d34-0410-b5e6-96231b3b80d8
