            Bug ID: 47586
           Summary: lld 10 fails to link mozilla rr: can't create dynamic
                    relocation R_386_32 against local symbol in readonly
                    segment
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P

When I try to compile mozilla rr (https://github.com/mozilla/rr) with lld
10.0.1 I get:

ld.lld: error: can't create dynamic relocation R_386_32 against local symbol in
readonly segment; recompile object files with -fPIC or pass '-Wl,-z,notext' to
allow text relocations in the output
>>> defined in CMakeFiles/fxregs_32.dir/32/x86/fxregs.c.o
>>> referenced by fxregs.c:64 (32/x86/fxregs.c:64)
>>>               CMakeFiles/fxregs_32.dir/32/x86/fxregs.c.o:(main)

The maintainer says that for him linking with lld 9 succeeds. See also the bug
report over at rr for this issue: https://github.com/mozilla/rr/issues/2650
