2008-10-24	Rewrite logic to figure out whether LR needs to	Dale Johannesen
	be saved/restored in the prolog/epilog. We need to do this iff something in the function stores into it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@58116 91177308-0d34-0410-b5e6-96231b3b80d8
2008-04-30	Tail call optimization improvements:	Arnold Schwaighofer
	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
2008-03-03	This is the initial check-in for adding register scavenging to PPC. (Currently,	Bill Wendling
	PPC-64 doesn't work.) This also lowers the spilling of the CR registers so that it uses a register other than the default R0 register (the scavenger scrounges for one). A significant part of this patch fixes how kill information is handled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@47863 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-29	Remove attribution from file headers, per discussion on llvmdev.	Chris Lattner
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@45418 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-08	implement __builtin_return_addr(0) on ppc.	Chris Lattner
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44700 91177308-0d34-0410-b5e6-96231b3b80d8
2007-12-08	refactor some code to avoid overloading the name 'usesLR' in	Chris Lattner
	different places to mean different things. Document what the one in PPCFunctionInfo means and when it is valid. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@44699 91177308-0d34-0410-b5e6-96231b3b80d8
2007-02-27	Duplicate use of LR, take 2.	Jim Laskey
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34666 91177308-0d34-0410-b5e6-96231b3b80d8
2007-02-27	Backing out Jim's LR spill changes. This was causing llvm-gcc bootstrapping	Evan Cheng
	to infinite loop: PPCMachineFunctionInfo.h updated: 1.2 -> 1.3 PPCRegisterInfo.cpp updated: 1.110 -> 1.111 PPCRegisterInfo.h updated: 1.28 -> 1.29 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34652 91177308-0d34-0410-b5e6-96231b3b80d8
2007-02-23	Don't spill LR as a callee saved register.	Jim Laskey
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34533 91177308-0d34-0410-b5e6-96231b3b80d8
2006-11-25	Add newline at end of file.	Reid Spencer
	git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31902 91177308-0d34-0410-b5e6-96231b3b80d8
2006-11-16	This is a general clean up of the PowerPC ABI. Address several problems and	Jim Laskey
	bugs including making sure that the TOS links back to the previous frame, that the maximum call frame size is not included twice when using frame pointers, no longer growing the frame on calls, double storing of SP and a cleaner/faster dynamic alloca. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31792 91177308-0d34-0410-b5e6-96231b3b80d8
