dw2-case-insensitive.exp: p fuNC_lang fails on arm. The problem occurs
when thumb mode code is generated. On ARM last bit of function pointer
value indicates whether the target function is an ARM (if 0) or Thumb
(if 1) routine. The PC address should refer to actual address in
either case. This patch adds new compile unit and function labels to
code which act as address ranges of compile unit and functions in
debug information. Therefore address ranges will have correct
addresses and not the ones with an incremented least significant bit.
This patch has been tested on x86_64 and arm machines.
gdb/testsuite/ChangeLog:
2013-11-14 Omair Javaid <Omair.Javaid@linaro.org>
* gdb.dwarf2/dw2-case-insensitive-debug.S: Updated compile unit
and function label names.
* gdb.dwarf2/dw2-case-insensitive.c: Created function and
compile unit labels.
