--- Comment #1 from Francois-Xavier Coudert <fxcoudert at gcc dot gnu.org> ---
I don't know enough to see if the asm in the code is incompatible with darwin
syntax, or if the middle-end should emit different asm.

Most likely the testcase needs:
/* { dg-require-effective-target nonpic } */

Or something like that.

this seems to have been fixed by r14-6423-g02f562484c1752, does it need back
porting? or should we close?
