Richard Biener suggested `-fno-var-tracking` or `-g0` as workaround and both indeed workaround the problem (see [2]). I don't yet know how to limit the addition of `-fno-var-tracking` to KBUILD_CFLAGS to `net/ipv4/fib_semantics.c` [...]
Ok, found what I need on [1]: ``` $(CFLAGS_$@) specifies per-file options for $(CC). The @ part has a literal value which specifies the file that it is for. [...] Example: # drivers/scsi/Makefile CFLAGS_aha152x.o = -DAHA152X_STAT -DAUTOCONF ``` [1]: https://github.com/torvalds/linux/blob/master/Documentation/kbuild/makefiles.rst I'll give that a try and if it works create a MR on [2] so kernel builds for ia64 can succeed with gcc-13 until that one is fixed.
