aix: Debugging does not require a stack frame.
The rs6000 port has allocated a stack frame when debugging is enabled
on AIX since the earliest versions of the port. Apparently the
earliest versions of the debuggers for AIX had difficulty with stackless
frames.
Both AIX DBX and GDB support stackless frames on AIX, and IBM XLC,
OpenXL and LLVM for AIX do not generate an extraneous stack frame when
debugging is enabled. This patch updates the rs6000 stack info function
to not set the stack frame flag when debugging is enabled for AIX.
gcc/ChangeLog:
* config/rs6000/rs6000-logue.cc (rs6000_stack_info):
Do not require a stack frame when debugging is enabled for AIX.
