set ml "undefined.c:9: undefined reference to `*this_function_is_not_defined'"
# With targets that use elf/dwarf2, such as the arm-elf and thumb-elf
# toolchains, the code in bfd/elf.c:_bfd_elf_find_nearest_line() is called
# in order to locate the file name/line number where the undefined
# reference occurs. Unfortunately this tries to use the dwarf2 debug
# information held in the .debug_info section. This section contains a series
# of comp_unit structures, each of which has a low/high address range
# representing the span of memory locations covered by that structure. The
# structures also index into other structures held in the .debug_line section
# and together they can translate memory locations back into file/function/line
# number addresses in the source code. Since the information about the memory
# region covered by a comp_unit is only determined at link time, the low/high
# addresses in the .debug_info section and the line addresses in the .debug_line
# section are computed by generating relocs against known symbols in the object
# code.
#
# When the undefined reference is detected, the relocs in the dwarf2
# debug sections have not yet been resolved, so the low/high addresses and the
# line number address are all set at zero. Thus when _bfd_elf_find_nearest_line()
# calls _bfd_dwarf2_find_nearest_line() no comp_unit can be found which
# actually covers the address where the reference occured, and so
# _bfd_elf_find_nearest_line() fails.
#
# The upshot of all of this, is that the error message reported by the
# linker, instead of having a source file name & line number as in:
#
# undefined.c:9: undefined reference to `this_function_is_not_defined'
#
# has an object file & section address instead:
#
# undefined.0(.text+0xc): undefined reference to `this_function_is_not_defined'
#
# hence the xfails below.

# The undefined test fails on 31 bit s/390 because the address of the
# function `this_function_is_not_defined' is stored in the literal pool of
# the function. Therefore the line number in the error message is 8 instead
# of 9. On 64 bit s/390 this works because of the new brasl instruction that
# doesn't need a literal pool entry.
