--- Comment #21 from Jonas Jelten <jj at stusta dot net> ---
I fear this is still present, I think due to
eb7892c4019bd5d00175c0eb80eb0c5a47a42ca1 and
3221c470f0765886a49a1a3d2ec602e4104a377b my testcase should work.
Tested on:
Gentoo: gcc 15.2.0 p5, ld.bfd 2.44-r1
Ubuntu 26.04dev: gcc 15.2.0-10ubuntu1 ld.bfd 2.45.50.20251201
+++ lib.c +++
#include <stdio.h>
int lib() {
printf("library function\n");
return 0;
}
+++ main.c +++
#include <stdio.h>
int __real_lib();
int __wrap_lib() {
printf("wrap lib\n");
__real_lib();
return 0;
}
int lib();
int main() {
printf("running func\n");
lib();
return 0;
}
% gcc -Wl,--wrap=lib lib.c main.c -o prog && ./prog
running func
wrap lib
library function
% gcc -Wl,--wrap=lib -flto lib.c main.c -o prog && ./prog
running func
