----- Forwarded message from "H. J. Lu" <hjl@lucon.org> ----- I will open a bug in gcc bugzilla when conversion is done. In the meantime, I opened https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=91056 The problem is gcc doesn't save/store gp across call. According to the ia64 ABI, callee can change gp and gp must be saved/restore by caller across calls. It is on page 5-2 in the Itanium Software Conventions and Runtime Architecture Guide. Am I right? ----- End forwarded message ----- I have put the entire thread at http://people.freebsd.org/~obrien/gcc-violate-ia64ABI.mbox -- -- David (obrien@FreeBSD.org)
