## We used to be wrong with some linker synthesized symbols.

## We mark __init_array_start as 'd', as consistent with GNU nm >= 2.33 (older GNU
## nm marks it as 't'). See https://sourceware.org/bugzilla/show_bug.cgi?id=24511

# CHECK: d __fini_array_start
# CHECK: d __init_array_start
# CHECK: d __preinit_array_start
# CHECK: B __bss_start
# CHECK: D _edata
# CHECK: B _end
