So to confirm, the issue is non-pic crt calling an init routine beyond the current 256 MB region? Otherwise for PIC the issue is dealt with by the assembler with the JAL <sym> being expanded to a load from the got and indirect call through t9. Previously t9 would not have been set up for the callee if the code was built non-pic (as it would just use a JAL). That would have made the setup of gp somewhat pointless in the CRT_CALL_STATIC_FUNCTION code. I am therefore a little confused by the existing code that sets up GP but then it seemingly is not used unless built for PIC. I need a little time to consider this further. Catherine may comment in the meantime. Thanks, Matthew
