            Bug ID: 32464
           Summary: ld allows adding 2 relative symbols. lld rejects
           Product: binutils
           Version: 2.43.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: stsp at users dot sourceforge.net
  Target Milestone: ---

Created attachment 15843
  --> https://sourceware.org/bugzilla/attachment.cgi?id=15843&action=edit
test-case

Attached is a test-case.

$ ./test.sh
bfd linked allowed this, BAD
ld.lld: error: kernel.ld:5: at least one side of the expression must be
absolute
lld linker rejected this, GOOD

The culprit is this expression
in linker script:
SHOULD_FAIL = . + .;

lld reject it with the above error
message, while bfd linker silently
allows. I believe it should be rejected.
