RTEMS PowerPC Applications Supplement
Each high-level language compiler generates subroutine entry and exit code based upon a set of rules known as the compiler's calling convention. These rules address the following issues:
A compiler's calling convention is of importance when interfacing to subroutines written in another language either assembly or high-level. Even when the high-level language and target processor are the same, different compilers may use different calling conventions. As a result, calling conventions are both processor and compiler dependent.
RTEMS supports the Embedded Application Binary Interface (EABI) calling convention. Documentation for EABI is available by sending a message with a subject line of "EABI" to eabi@goth.sis.mot.com.
