If a function returns a large struct by value return the first 4 words in registers and the rest on the stack in a location reserved by the caller. This is needed to support the xC language which supports functions returning an arbitrary number of return values. This is r202397 reapplied with a fix to avoid an uninitialized read of a member. llvm-svn: 202414 |
