37 | // and in the shared library. We can't use the visibility attribute | |
38 | // here, becaues that may cause gcc to generate a PC relative reloc; | |
39 | // we need it to get the value from the GOT. I'm not sure this is | |
40 | // really useful, given that it doesn't work with the visibility | |
41 | // attribute. This test exists here mainly because the glibc | |
42 | // testsuite has the same test, and we want to make sure that gold | |
43 | // passes the glibc testsuite. | |
