commit r16-6721-g0c775dcf3e78148204b78022dfd3de4a0833f496 Author: Maciej W. Rozycki <[email protected]> Date: Mon Jan 12 13:08:28 2026 +0000 libiberty: Make `objalloc_free' `free'-like WRT null pointer Inspired by a suggestion from Jan Beulich to make one of `objalloc_free' callers `free'-like with respect to null pointer argument handling make the function return with no action taken rather than crashing when such a pointer is passed. This is to make the API consistent with ISO C and to relieve all the callers from having to check for a null pointer. libiberty/ * objalloc.c (objalloc_free): Don't use the pointer passed if null.
