stabs+ vs dwarf-2

[Art Berggreen]

Are there any issues using stabs+ rather than dwarf-2 debugging info
with GDB?

We are using an arm-elf build of GCC which defaults to dwarf-2.  But gas
appears to want (need?) stabs directives to perform source code
inclusion in assembly listing files (-ahls).  If I tell GCC to produce
stabs+ directives, I get the desired assembly listing, but was wondering
if there is a downside.  The target is a custom board with no formal
OS.  GCC version 2.95.2, gas version 2.9.5, gdb version 4.18.
