Hi Keith,
just fixed up / simplified the testcase.
m68k: gdb.dwarf2/pr11465.S:44: Error: unknown pseudo-op: `.value'
And with -nostdlib link to executable:
/usr/bin/ld: Dwarf Error: Can't find .debug_ranges section.
/usr/bin/ld: Dwarf Error: mangled line number section (bad file number).
/usr/bin/ld: Dwarf Error: mangled line number section (bad file number).
/usr/bin/ld: Dwarf Error: mangled line number section (bad file number).
/usr/bin/ld: Dwarf Error: mangled line number section (bad file number).
