It would seem more desireable given the intended purpose to avoid pushing it on the stack so that it's elements may be more effeciencly accessed, that it's coresponding elements be allocated within the register file (as opposed to the whole struct remaining packed into an alllocated DI mode integer), so that it's elements may be effeciently accessed without needing to rip them out or reassemble them into the otherwise packed monolithic structure? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=11180
