The Valgrind sources contain test programs, including expected outputs, for all SSE/SSE2/SSE3 instructions on amd64 (see none/tests/amd64/insn-sse and insn-sse2). Running those on QEMU might be a quick and easy first check for something wrong in the SSE department. They are not completely comprehensive but may find obvious arithmetic errors and instruction decoding errors. J
