marcel 2002/11/11 00:11:44 PST Modified files: sys/ia64/include setjmp.h lib/libc/ia64/gen _setjmp.S setjmp.S sigsetjmp.S Log: ia64 ABI breaker: Don't force 16-byte alignment at run-time. Do it at compile-time. This saves us the pointer fiddling by the setjmp functions and reduces complexity. While here, increase the jmp_buf by 16 bytes to an even 512 bytes. Coincidentally, due to the way alignment was handled prior to this change, the jmp_buf has not changed in size, but only in how the space is used. Prior to this change the 16 bytes were reserved for enforcing alignment; now they are reserved by us for future extensions. Therefore, this ABI breaker is relatively save: the failure is always an alignment trap.
