Hi, I'm trying to finally make XView work on IA64. This is old and ugly sourcecode from Sun and of course, the assumption sizeof(int)==sizeof(long)==sizeof(void *) is causing lots of problems. Additionally, the whole API is based on stdarg and this is causing the problem where I'm currently stuck:
According to the IA64 ABI, all arguments for stdarg-functions are passed in 64 bit slots. However, if you just pass a 32 bit quantity, then the upper 32 bits of the slot are undefined. Is there any way to avoid this (i.e. can you force the unused part of the slot to be initialized to 0)? Without this, I fear porting XView to IA64 will require much more effort than I can justify. Thanks, Martin
