            Bug ID: 42329
           Summary: lld ignores symbols declared as EXTERN in linker
                    script
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: ELF
          Assignee: unassignedbugs at nondot.org

ld.lld has a different behavior compared to GNU ld when it comes to adding
undefined symbols from a linker script. Here's a simple test case:

$ touch a.c
$ clang -c a.c -o a.o
$ echo "EXTERN(test)" > a.lds
$ ld.lld -T a.lds a.o -o a.out
$ objdump -t a.out | grep test
$

The resulting file doesn't contain the "test" symbol, which was added through
the linker script. With GNU ld on the other hand:

$ ld -T a.lds a.o -o a.out
$ objdump -t a.out | grep test
0000000000000000         *UND*  0000000000000000 test
