As Alan predicted at https://sourceware.org/ml/binutils/2017-10/msg00137.html the values in some Arm tests need updating after recent changes. These looked a bit spooky at first, but they are just a difference in the order we emit veneers and far jumps, so are not so scary after all.
Checked with an arm-none-eabi tester and an arm-none-linux-gnueabi tester with no issues. * testsuite/ld-arm/cortex-a8-far.d: Update expected disassembly. * testsuite/ld-arm/farcall-group-size2: Likewise. * testsuite/ld-arm/farcall-group.d: Likewise.
