--- Comment #2 from H.J. Lu <hjl.tools at gmail dot com> --- [hjl@gnu-cfl-2 tmp]$ gcc -pie -fPIE -O2 tst-relr.c -Wl,--pack-dyn-relocs=relr -fuse-ld=lld [hjl@gnu-cfl-2 tmp]$ ./a.out Segmentation fault (core dumped) [hjl@gnu-cfl-2 tmp]$ Given that the current lld implementation generates broken binaries for existing glibc without any warning at run-time, we need a different linker command line option to implement it properly so that the new binary will fail to run on glibc without DT_RELR support at run-time. We can do "-z relr=glibc" which generates DT_RELR and adds a glibc version dependency against the first version of glibc with DT_RELR support. -- You are receiving this mail because: You are on the CC list for the bug.
