Comment 1 Gustavo Zacarias 2015-03-18 10:05:41 UTC 
Care to provide a config?
I was able to build qemu_sparc_ss10_defconfig switching to gcc 4.9.2 just fine and it even boots.
Comment 2 Uwe Hermann 2015-03-19 15:40:03 UTC 
Yup, qemu_sparc_ss10_defconfig works for me as well. The attached config (based on a fresh checkout, "make menuconfig" and only minimal changes to the config settings) doesn't build for me though.
