When I last played with the powerpc many years ago, the main differences between Linux and eabi was some details that you may or may not run into (note these are from memory, so you probably need to check what the current reality is): 1) eabi had different stack alignments than Linux; 2) eabi uses 2 small data registers (r2, r13) and Linux only 1 (r13?). 3) There are eabi relocations not officially in Linux and vice versa, but the GNU linker should support any relocations the compiler uses. 4) eabi can be little endian, Linux is only big endian. 5) different system libraries were linked in by default. -- Michael Meissner AMD, MS 83-29 90 Central Street Boxborough, MA 01719
