            Bug ID: 31299
           Summary: lld prints basename of source file name in error
                    messages
           Product: lld
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P
         Component: ELF
          Assignee: unassignedbugs at nondot.org
          Reporter: roland at hack.frob.com
                CC: llvm-bugs at lists.llvm.org, phosek at chromium.org
    Classification: Unclassified

Test case:

    $ mkdir foo
    $ echo 'void _start(void) { foobar(); }' > foo/bar.c
    $ gcc -g -c foo/bar.c
    $ bin/ld.lld -o out bar.o 
    bin/ld.lld: error: bar.c:1: undefined symbol 'foobar'
    $

This should say:

    bin/ld.lld: error: foo/bar.c:1: undefined symbol 'foobar'

File names in DWARF info must be assembled from both the directory table
and the file name table in .debug_line.  It looks like lld is using only
the file name table.
