            Bug ID: 26814
           Summary: lld needs to set DF_TEXTREL if the output contains
                    relocations in non-writable segments
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: FreeBSD
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs
          Assignee: unassignedbugs at nondot.org

PR 26813 reports an issue where an lld-linked FreeBSD libc contains .text
relocations, which should not be the case.

However, if the output does contain .text relocations the DF_TEXTREL flag needs
to be set (and perhaps the DT_TEXTREL tag).

Split into a separate PR for tracking.

> If this flag is not set, no relocation entry should cause a modification
> to a non-writable segment, as specified by the segment permissions in the
> program header table. If this flag is set, one or more relocation entries
> might request modifications to a non-writable segment, and the dynamic 
> linker can prepare accordingly.
