Thread: Call stack trace implementation
Call stack trace implementation
user name

My question is on implementation of stack backtrace on
architures,
MIPS and PPC. Is the implementation based on libunwind and
unwind
directives in the executable?  Or is it based on older code
which
analyzes prologue of a function? Or a mix of both
approaches?
Thanks

Both prologue analysis and call frame information. 
Libunwind is not
used except on IA64; GDB has its own support for DWARF-2
unwind tables.
