Do you remember what those features are Renato? MC has been around
years, we really should start sorting them now.

Here's where we left off:

In 3.4, I think the integrated assembler is in excellent shape and
should be enabled by default for ARM ELF.  I've been using it
exclusively for at least 6 months now.

Back then you mentioned a Chromium build, are you still running that
routinely with -integrated-as? That would give a reasonable
reassurance about general-usage, if not weird features.

Cheers.

No. I remember there were issues, but I never catalogued them.

I agree we should move as soon as possible, and there's nothing holding me
of doing it.

I think post-3.4 we can cope with the consequences if they come, since it
seems nobody remembers what they were in the first place. ;)

Looks like there might be a handful of .eabi_attribute variantswe
can't handle (http://llvm.org/bugs/show_bug.cgi?id=15172) -- ones
involving a string?

Cheers.
