Subject: Linux-6.17 meets gcc trunk

Hello there,

I just tried to compile linux-6.17 with gcc trunk. It said:

  HDRINST usr/include/asm/types.h
In file included from scripts/gcc-plugins/latent_entropy_plugin.c:78:
scripts/gcc-plugins/gcc-common.h:176:25: error: ‘TODO_verify_il’ was not declared in this scope; did you mean ‘TODO_verify_flow’?
  176 | #define TODO_verify_ssa TODO_verify_il
      |                         ^~~~~~~~~~~~~~
scripts/gcc-plugins/latent_entropy_plugin.c:567:27: note: in expansion of macro ‘TODO_verify_ssa’
  567 | #define TODO_FLAGS_FINISH TODO_verify_ssa | TODO_verify_stmts | TODO_dump_func \
      |                           ^~~~~~~~~~~~~~~
scripts/gcc-plugins/gcc-generate-gimple-pass.h:86:43: note: in expansion of macro ‘TODO_FLAGS_FINISH’
   86 |                 .todo_flags_finish      = TODO_FLAGS_FINISH,


gcc trunk is at https://gcc.gnu.org/git.html. This error has been occurring
for a few weeks now, so I don't think it is transitory.

The kernel configure script is:

$ make distclean allyesconfig
