            Bug ID: 48621
           Summary: lld can't build working static PIE on Linux/x86-64
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: ELF
          Assignee: unassignedbugs at nondot.org

When elf/ldconfig in glibc configured with --enable-static-pie is built
with lld on Linux/x86-64, I got

[hjl at gnu-skx-1 build-x86_64-linux]$ ./elf/ldconfig
Segmentation fault (core dumped)
[hjl at gnu-skx-1 build-x86_64-linux]$ 

One difference between lld generated ldconfig vs ld generated ldconfig is

lld:

Relocation section '.rela.dyn' at offset 0x318 contains 1469 entries:

ld:

Relocation section '.rela.dyn' at offset 0x398 contains 1434 entries:

If lld can generate the same number of dynamic relocations as ld, static PIE
may work with lld.
