Suggestion: In AIX's implementation of LLU (Live Library Update), the caller of a Virtual API (VAPI) interface instead calls VAPI glue and the implementation for a VAPI function is entered from the VAPI glue. If a VAPI is not already active on the thread, the VAPI calls the implementation of the VAPI function with the link register (LR) value set to a return address in the VAPI glue. In this case, the LR (return address) value on entry to the VAPI glue is saved in the VAPI control block. https://github.com/llvm/llvm-project/pull/209280 _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
