This is probably due to the ISA level. The HG556a seems to use MIPS32r1 and the OM2P uses MIPS32r2. I think LLVM defaults to MIPS32r2 unless told otherwise. It would be interesting to get a disassembly at the SIGILL, then I could tell you for certain that this was the problem. M...
The address of the current instruction is kept in the 32-bit program counter (PC) register. To execute the code in Figure 6.29, the PC is initialized to address 0x00000830. The processor fetches the instruction at that memory address and executes the instruction, 0x01498933 (add s2, s3, ...

The handling of branch delay slots in MIPS microprocessors is enhanced. Branch instructions can be placed in branch delay slots by the judicious operation of the Exception Pointer Counter and the BD bit in the Cause register for exception handling.Frank Worrell...
