------- Comment From [email protected] 2016-02-24 19:04 EDT------- One thing I noticed may be relevant since we're talking about -Os code, which means out-of-line register save and restore functions. gcc-5 moves some code before the register save call, while gcc-4.9 doesn't seem to. It is important that the call to functions like _savegpr0_14 *not* go through stubs (for example to reach a destination more than 33M away) that might destroy regs. The save/restore functions have non-standard calling conventions, so you can't use stubs that destroy *any* of the volatile regs. In particular, r0, r11 and r12 are not available for use by a stub.
