[PATCH] D67963: [MIPS GlobalISel] Lower aggregate structure return arguments

[Petar Avramovic via Phabricator via llvm-commits]

Petar.Avramovic added a comment.

I also looked into MipsABIInfo today and it doesn't allow any aggregate structure like argument for O32, and only aggregate structure that can be encountered is return value that has ComplexType. Even  structure with two floats or doubles returns get transformed into pointer argument despite the fact it is similar thing as complex float or complex double.
I am not so sure about correctness for aggregate struct arguments since I can't generate them with clang, and for that reason I would mark aggregate structures arguments as unsupported for now, and only handle aggregate structure returns. When test with aggregate structure arguments appears we can add handling for it.
