tests of the Intel syntax should be added to prevent bitrot (including
relocatable expression syntax, etc). Test file dual03.s uses Intel
syntax lightly (i.e., register names without '%' prefix).
+ - Currently, .align in a .text section fills with 0x00000000. This is
+ a defect and it needs to fill with nop (0xa0000000). Write a testcase

Contact me (Jason Eckhardt, jle@rice.edu) if you'd like to help.
Known testsuite failures:
- - dual02-err.s: GAS currently doesn't check that dual mode pairs
