Dan Gohman 61a9213440 Implement an x86-64 ABI detail of passing structs by hidden first ... argument. The x86-64 ABI requires the incoming value of %rdi to be copied to %rax on exit from a function that is returning a large C struct. Also, add a README-X86-64 entry detailing the missed optimization opportunity and proposing an alternative approach. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@50075 91177308-0d34-0410-b5e6-96231b3b80d8		2008-04-21 23:59:07 +00:00
