# The ARM asm is written in ARM RVCT syntax, but we actually build it with
# gas using GNU syntax. Add some rules to perform the conversion.

# Previously used $(dir $(ASFILES)) to figure out which directories to generate.
# However, .S (as opposed to .s) files are not added to ASFILES. There is only
# one directory with arm assembly currently so enumerate it manually.
