--- Comment #5 from Iain Sandoe <iains at gcc dot gnu.org> ---
So the reason that Segher and I were seeing different results is that I was
using the default BINUTILS on the platform (2.27) and Segher was using 2.31.
The salient difference appears to be this (from auto-host.h):
2.27 .... 2.31
/* #undef HAVE_AS_PLTSEQ */ | #define HAVE_AS_PLTSEQ 1
As a second point - I checked r266557 and that produces correct code with:
GNU assembler version 2.27 (ppc64-redhat-linux) using BFD version version
2.27-28.base.el7_5.1
It's possible that the patch sequence 266599-266610 could have caused this.
