[Bug target/60610] [4.9 Regression] ICE in convert_regs_1, at reg-stack.c:3064
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60610 Richard Biener rguenth at gcc dot gnu.org changed: What|Removed |Added Target Milestone|--- |4.9.0 --- Comment #1 from Richard Biener rguenth at gcc dot gnu.org --- Note that the weird thing is that with 4.8 I get [ 127s] GRUB2 will be compiled with following components: ... [ 127s] efiemu runtime: No (cannot compile with -m64 -mcmodel=large -mno-red-zone -nostdlib) but appearantly with 4.9 that succeeds (the compiler wasn't built with multilibs) [ 153s] efiemu runtime: Yes so maybe this isn't a true regression. It's at least odd.

I can reproduce this, looking into it now. 4.8 configured the same way would complain: error: code model ‘large’ not supported in the 32 bit mode sorry, unimplemented: 64-bit mode not compiled in but 4.9 doesn't for some reason.
