```
It looks like the test needs to be fixed up similar to
gcc.target/i386/cold-attribute-4.c, but it doesn't look like gccjit has a way
to provide a string optimization level option, so I suppose that needs to be
improved to allow the test to be fixed. Setting component to jit for that.
The fix was backported at least as far as gcc14.
