[RFC,2/6] ARC: Fixed inline asm contraints to gcc 6.x
Commit Message
From: Cupertino Miranda <cmiranda@synopsys.com>
It seems glibc had some ancient ARC bits, added as part of some header
sync up back in 1999 (I was still in college)
That code obviously doesn't build with modern compilers.

longlong.h should be kept in sync with GCC. If the GCC version has been
fixed we can copy the updated version verbatim from GCC.

Indeed it is fixed in upstream gcc.

[ARC] Fix obsolete constrain
So I drop this patch from my series and rely on glibc upstream to have this fixed ?

Don't drop the patch; replace it with a patch that copies the file
verbatim from the GCC source tree.
