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

This was fixed here:
https://git.kernel.org/linus/a40282dd3c484e6c882e93f4680e0a3ef3814453
It will need backporting to prior kernel releases.
