[cfe-dev] -faddrsig vs systems using GNU binutils

[Michał Górny via cfe-dev]

Hello,

Clang currently defaults to emitting address significance table
(-faddrsig) on majority of the systems.  Of those systems, at least
Gentoo still defaults to using GNU binutils most of the time.
As a result, strip(1) now outputs verbose errors on clang-created
executables, e.g.:

armv7a-unknown-linux-gnueabihf-strip: st5EpxDK: failed to find link
section for section 6
armv7a-unknown-linux-gnueabihf-strip: st5EpxDK: failed to find link
section for section 6

We (Gentoo) have received user reports about this [1].  We have passed
this on to GNU binutils [2] but it seems that they not only aren't
interested in providing any support for this section but actively
indicate that the proposed standard is unlikely to be accepted into
generic-abi.

Could you advise on how to proceed?  I'm thinking of disabling it
by default but I would prefer not to add unnecessary distro
customization if possible.
