Hi,<div><br></div><div>I haven't been able to reproduce this problem on a smaller test and the original source code is from another virtual machine's IR. What I found out was that 42 << 7 is actually DPSoRegImmFrm, defined in ARMInstrFormats.td. This format is not dealt with in the ARMCodeEmitter.cpp and that's the problem I'm facing.</div>
<div><br></div><div>The triple I'm using is "armv7-unknown-linux-gnueabi" and the bitcode I'm dealing with is:</div><div><br></div><div><div><font color="#006600"> ; ModuleID = 'CRYO jit'</font></div>
