After it failed finding a legal vector type by promoting it would continue using
the promoted vector element type. Thereby missing legal splitted vector types.

By resetting the vector element type to the original vector element type that
existed before the promotion the code will attempt to split the vector type to

Jakob Stoklund Olesen [Sat, 6 Apr 2013 23:57:33 +0000 (23:57 +0000)]
Implement LowerReturn_64 for SPARC v9.

Integer return values are sign or zero extended by the callee, and
structs up to 32 bytes in size can be returned in registers.

The CC_Sparc64 CallingConv definition is shared between
LowerFormalArguments_64 and LowerReturn_64. Function arguments and
return values are passed in the same registers.

The inreg flag is also used for return values. This is required to handle
C functions returning structs containing floats and ints:

  struct ifp {
    int i;
    float f;
  };

  struct ifp f(void);

LLVM IR:

  define inreg { i32, float } @f() {
     ...
     ret { i32, float } %retval
  }

The ABI requires that %retval.i is returned in the high bits of %i0
while %retval.f goes in %f1.

Without the inreg return value attribute, %retval.i would go in %i0 and
%retval.f would go in %f3 which is a more efficient way of returning
%multiple values, but it is not ABI compliant for returning C structs.

Complete formal arguments for the SPARC v9 64-bit ABI.

All arguments are formally assigned to stack positions and then promoted

point registers than integer registers, this can cause situations where
floating point arguments are assigned to registers after integer
arguments that where assigned to the stack.

Use the inreg flag to indicate 32-bit fragments of structs containing
both float and int members.

The three-way shadowing between stack, integer, and floating point
registers requires custom argument lowering. The good news is that

- All other cases are consider overrides, which do not inherit

move availability/deprecated up and down a class/protocol hierarchy.
