Do you mean a test-suite run that passes integrated-as? There's the
usual clutch of regression tests that pass, but I don't know if any
build-bots run anything using it.

Unfortunately I suspect the things that are most likely to fall over
are weird bare-metal systems people have that rely on esoteric ELF
properties in some way. I suspect I could break ELF output in a dozen
ways without affecting what actually happens on arm-none-linux-gnueabi
with a standard linker.

Certainly agreed there. It's best to have a good run-up where people
can file bugs.
