| ## Handle unrecognized arch attributes. |
| ## Encode an unrecognized arch feature into an object file and try to decode it. |
| ## The expected behavior is to ignore the unrecognized arch feature and |
| ## continue to process the following arch features. |
| ## |
| ## The object file has the "rv32i2p0_x1p0_m2p0" arch feature. "x1p0" is an |
| ## unrecognized architecture extension. llvm-objdump will ignore it and decode |
| ## "mul" instruction correctly according to "m2p0" in the arch feature. |
| ## |
| ## This test cannot be assembly because the test needs an unrecognized arch |
| ## feature and `llvm-mc` will filter out the unrecognized arch feature. |
