           Summary: Assertion failure calling function with struct-typed phi
                    value
           Product: new-bugs
           Version: unspecified
          Platform: PC
        OS/Version: FreeBSD
            Status: NEW
          Severity: normal

Created an attachment (id=1878)
 --> (http://llvm.org/bugs/attachment.cgi?id=1878)
Test case.

Compiling the attached bitcode produces the following error:

$ llc bugpoint-reduced-simplified.bc 
Assertion failed: (0 && "Unknown type!"), function getMVT, file ValueTypes.cpp,
line 109.

The same error appears when it's compiled using the JIT.  It appears to be
related to the phi node, since generating the same function call without a
value which was returned directly from a function (not accessed via a phi
instruction) compiles and generates the correct (ABI-compliant) code.
