antangelo added a comment.
Rebased, updated release notes, updated .thumb to align to a 2-byte boundary, and added a test case
To my knowledge (testing with arm-none-eabi), the GNU assembler aligns code after the .arm directive to the next
4-byte boundary when switching from thumb to ARM mode. It does not seem to emit any alignment when switching
from ARM to thumb mode with .thumb.
