Marcel Moolenaar db7ffe67c6 Rewite _start(). We cannot use a C function due to the fact that we ... don't call it according to the runtime specification and especially WRT to gp this can cause trouble. The gcc 3.3.1 import broke the ia64 runtime because the compiler saved gp prior to us being able to set it properly. Restoring gp after the calls would then invalidate gp and cause segmentation faults later on. By rewriting _start() as an assembly function, we also avoided even more gcc dependences, by trying to use gcc specific features to work around the problem. This version of _start() does not reference _DYNAMIC. We register the cleanup function when it's a non-NULL pointer. The kernel will always pass a NULL pointer and dynamic linkers may pass a non-NULL pointer. The machine independent code to set __progname now unfortunately is written in assembly. So be it.		2003-07-13 23:11:37 +00:00
