Good day,
I wanted to upgrade my kernel to the latest 5.15.162 but it seems to fail with this error message after upgrading to fedora 40, any ideas what could be the problem?
$ make HOSTCXX scripts/gcc-plugins/randomize_layout_plugin.so scripts/gcc-plugins/randomize_layout_plugin.c: In function 'bool dominated_by_is_err(const_tree, basic_block)': scripts/gcc-plugins/randomize_layout_plugin.c:693:20: error: 'last_stmt' was not declared in this scope; did you mean 'call_stmt'? 693 | dom_stmt = last_stmt(dom); | ^~~~~~~~~ | call_stmt make[2]: *** [scripts/gcc-plugins/Makefile:48: scripts/gcc-plugins/randomize_layout_plugin.so] Error 1 make[1]: *** [scripts/Makefile.build:552: scripts/gcc-plugins] Error 2 make: *** [Makefile:1246: scripts] Error 2
Maybe a problem with gcc 14?
This seems to fix the compiler error: https://lore.kernel.org/all/20230811060545.never.564-kees@kernel.org/
Maybe, has any previous 5.15.y kernel worked?
My current kernel was compiled with gcc 13: [ 0.000000] [ T0] Linux version 5.15.160 (thomas2@localhost.localdomain) (gcc (GCC) 13.3.1 20240522 (Red Hat 13.3.1-1), GNU ld version 2.40-14.fc39) #15 PREEMPT Sat Jun 1 16:54:27 CEST 2024
If you build 5.15.160 with gcc 14 does it also fail? Doing a 'git bisect if it does not would be great to track down the offending commit.
thanks,
