Building the openbios package fails with cross-gcc 5.2* and binutils 2.25.1*. I noticed this on f23 originally where 5.2 is in the stable repo, but also reproduced on f22. Packages that work fine on f22: binutils-powerpc64-linux-gnu.x86_64 2.25-4.fc22 binutils-sparc64-linux-gnu.x86_64 2.25-4.fc22 cross-binutils-common.noarch 2.25-4.fc22 cross-gcc-common.noarch 5.1.1-3.fc22 gcc-powerpc64-linux-gnu.x86_64 5.1.1-3.fc22 gcc-sparc64-linux-gnu.x86_64 5.1.1-3.fc22 Packages that fail on f22 (from updates-testing): binutils-powerpc64-linux-gnu.x86_64 2.25.1-1.fc22 binutils-sparc64-linux-gnu.x86_64 2.25.1-1.fc22 cross-binutils-common.noarch 2.25.1-1.fc22 cross-gcc-common.noarch 5.2.1-3.fc22 gcc-powerpc64-linux-gnu.x86_64 5.2.1-3.fc22 gcc-sparc64-linux-gnu.x86_64 5.2.1-3.fc22 Steps to reproduce: fedpkg co --anonymous openbios cd openbios fedpkg local

The tlbie instruction has a second argument from power7 onwards. The bug is in the openbios code, not the assembler. .machine power7 .text .align 2 tlbie 28 fails, but: .machine power7 .text .align 2 tlbie 28,0 works.
Note that gcc should be given an explicit power setting rather than relying on the default. gcc gives -mpower7 to the assembler without any instruction to the contrary.
Thanks David, I brought it up on the openbios mailing list
I've proposed a fix: http://www.openfirmware.info/pipermail/openbios/2015-November/008878.html
Fix is upstream now: commit 56f5de9b6177f1451e864efe45f7d121555d5608 Author: mcayland <mcayland@f158a5a8-5612-0410-a976-696ce0be7e32> Date: Wed Feb 3 20:46:31 2016 +0000 ppc: force target cpu With gcc-5.2 default target is power7. - For 32-bit PPC builds set the target cpu to 604 in order to support PReP as well as Macs in the future. - For 64-bit PPC builds set the target cpu to 970 as used in 64-bit Macs but disable altivec. Based on an original patch by Laurent Vivier <laurent@vivier.eu>.
