23 | /* This file tests the GAS's ability in assembling the alias mnemonics | |
24 | of sbfm, bfm and ubfm. Disassembler should prefer to use alias | |
25 | mnemonics to display {[u|s]}bfm instructions. | |
26 | bitfield-bfm.s and bitfield-alias.s will be assembled into idential | |
27 | binary, which is why the two tests share the same dump match | |
28 | file 'bitfield-dump'. | |
29 | This assembly file is also used for the bitfield-no-aliases test. */ | |
