Arnold Schwaighofer 30e62c098b Tail call optimization improvements: ... 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		2008-04-30 09:16:33 +00:00
