[llvm-commits] [PATCH] Test NEON code generation and calling convention

[Edmund Grimley-Evans]

Could this file (vadd2.ll) be added in test/CodeGen/ARM/?

It broke in r103411 and was fixed again in r103854. It would be nice
to keep it working.

I'm not sure what if any official rules govern how vector quantities
should be passed as arguments and returned. It appears that vectors of
less than 64 bits (such as the <2 x i8> in the first example in
vadd2.ll) currently get passed in R0-R3 rather than Q0-Q3, which leads
to some ugly code. Is this a bug or a feature?
