Major calling convention code refactoring.2009-08-05T01:29:28ZDan Gohmangohman@apple.com2009-08-05T01:29:28Zurn:sha1:98ca4f2a325f72374a477f9deba7d09e8999c29b
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.

Fix Bug 4278: X86-64 with -tailcallopt calling convention2009-06-12T16:26:57ZArnold Schwaighoferarnold.schwaighofer@gmail.com2009-06-12T16:26:57Zurn:sha1:bbd8c33ee67f99f5bad7288dfa465d675714e983
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.
