I'll compare r165239 to (r165240 plus your commit at r165382), ok? Looking at r165240, I have a hunch that we're going to find a function call to a libgcc function with the stack-pointer at an...awkward state. cris.h: #define BIGGEST_ALIGNMENT 8 #define STACK_BOUNDARY \ (TARGET_STACK_ALIGN ? (TARGET_ALIGN_BY_32 ? 32 : 16) : 8) (i.e. 8 for cris-elf default.)
