... but when I do this in regex.c of uclibc, I get a ton of 'Branch out
of range' errors from the assembler - so I guess there'd be some more
fixing in arm.md. Should I file this as a bug report, too - but I guess
it'd be hard to come op with a small example, since you need at least 1k
(?) of code?
