RVCT and ADS make long jump be possible by adding veneer. But, interestingly, link tool of RVCT and ADS, added veneer only when jump to the code located in other execution area. So, in the case that long jump to the same-execution-area-code is needed, linker generates "memory relocation error" in ADS and RVCT. That's why we need to classify code and put them into several execution area.

TI's TMS470 adds veneer('Trampoline' in TMS) even if target code of long jump is in same execution area. But TMS470 is very slow... :-(

I have no idea about gnu arm eabi tools...
