Dan Gohman	f9bbcd1afd	Major calling convention code refactoring. ... 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. llvm-svn: 78142	2009-08-05 01:29:28 +00:00
Arnold Schwaighofer	e3a018d707	Fix Bug 4278: X86-64 with -tailcallopt calling convention ... out of sync with regular cc. The only difference between the tail call cc and the normal cc was that one parameter register - R9 - was reserved for calling functions through a function pointer. After time the tail call cc has gotten out of sync with the regular cc. We can use R11 which is also caller saved but not used as parameter register for potential function pointers and remove the special tail call cc on x86-64. llvm-svn: 73233	2009-06-12 16:26:57 +00:00
