...een successful with a 16-bit target? I'm new to LLVM and am having problems. One problem I found stems from code in lib/CodeGen/SelectionDAG/SelectionDAGISel.cpp: visitRet(): // If this is an integer return value, we need to promote it ourselves to // the full width of a register, since getCopyToParts and Legalize will use // ANY_EXTEND rather than sign/zero. // FIXME: C calling convention requires the return type to be promoted to // at least 32-bit. But this is not necessary for non-C calling conventions. if (MVT::isInteger(RetOp.getValueType()) && RetOp.getValueType() &...

...// conventions. if (VT.isInteger()) { MVT MinVT = TLI.getRegisterType(MVT::i32); if (VT.bitsLT(MinVT)) VT = MinVT; } This is occurring when VT is a 16bit vector type,<2x i8>. LLVM is then changing it to be a 32bit type and it asserts in : getCopyToParts(DAG, SDValue(RetOp.getNode(), RetOp.getResNo() + j), &Parts[0], NumParts, PartVT, ExtendKind); Here: assert(ValueVT.getVectorElementType() == PartVT && ValueVT.getVectorNumElements() == 1 && "Only trivial vector-to...

I just tried building the latest clang following the instructions in http://clang.llvm.org/get_started.html, and got this error when trying to compile at test program: /usr/bin/ld: cannot find /home/davem/clang-235334/bin/../lib/clang/3.7.0/lib/linux/libclang_rt.asan-x86_64.a: No such file or directory This thread: http://lists.cs.uiuc.edu/pipermail/llvmdev/2015-April/084175.html indicates
