A bug in the IPA inliner caused a segfault when a target rejected inlining for reasons other than general optimization settings. This occurred because the compiler attempted to print details about the rejected inlining even when the relevant data was null. The fix adds a null check before calling the print function, preventing the crash and improving robustness for targets like MIPS with specific inlining constraints.
