            Bug ID: 115953
           Summary: --wrap does now work with lto
           Product: gcc
           Version: 12.3.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: lto
          Assignee: unassigned at gcc dot gnu.org
          Reporter: koule2333 at gmail dot com
  Target Milestone: ---

I am using gcc 12.3.1 and ld 2.41, and this error occurs again.
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88643

my case:

int foo();

int __wrap_foo() {
    return 6;
}

int main() {
    return foo();
}

When I use 'gcc -flto ccc.c -Wl,--wrap=foo' to compile it, I got undefined
reference to `__wrap_foo'.

Can anyone tell me why?
