Hi Sirl,

As you mentioned in Bugzilla (comment 13),
aix_return ( return in memory)
svr4_return (return in register)
what is the semantics of svr4gnu w.r.t. return.


Hi Lokesh,

I don't quite understand what you are asking me here? In comment 13

I've talked about the option naming, which I was unsure about. In theend (before I was stuffed with other work again) I was settling for-msvr4-struct-return=standard and -msvr4-struct-return=gnu (which wouldbe the default and is equal the current behaviour), leaving-maix-struct-return unchanged.


What else do you want to know?

Franz
