5.15.x: randomize_layout_plugin.c: 'last_stmt' was not declared in this scope?

[Thomas Meyer <thomas@m3y3r.de>]

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?

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

$ gcc --version
gcc (GCC) 14.1.1 20240522 (Red Hat 14.1.1-4)

any help appreciated.

with kind regards
thomas
