[cfe-commits] [PATCH] vecreturn attribute support

[Sergey Epanchintsev]

Hello everyone,

Please review the attached patch.

It adds vecreturn attribute functionality to get a single element structure
or class (declared with 'vecreturn' attribute) compiled to IR so it  will be
returned by value.

I have unit tests but will submit them with a separate patch - I want to
keep my first patch small and clean. :)

As a headsup; I will submit a patch for SemaDeclAttr.cpp to support
vecreturn with C++ classes after this patch will be accepted.

Cheers,
Sergey.
