# running code. These provide the addresses only. This utility can be
# used to decode the backtrace into a readable form:
#
# Example
# Example:
# If the following lines were pasted into the shell after running decode_backtrace.py
#
# INFO Backtrace: 10
# INFO ./mainapp(px4_backtrace+0x27) [0x42b0d1]
# INFO ./mainapp() [0x42d44d]
# INFO ./mainapp() [0x42d3c6]
# INFO ./mainapp(px4_backtrace+0x27) [0x42b212]
# INFO ./mainapp() [0x42d608]
# INFO ./mainapp() [0x42d57e]
# INFO ./mainapp() [0x4ba48d]
#
# The output would be:
# 0x42b0d1 _sighandler (0x42b15b)
# 0x42d44d ACCELSIM::devRead(void*, unsigned long) (0x42d4be)
# 0x42d3c6 ACCELSIM::stop() (0x42d442)
#
# The output is:
# 0x42b212 px4_backtrace (0x42b1eb)
# 0x42d608 ACCELSIM::devRead(void*, unsigned long) (0x42d600)
# 0x42d57e ACCELSIM::start() (0x42d578)
# 0x4ba48d DriverFramework::DevObj::addHandle(DriverFramework::DevHandle&) (0x4ba42e)
#
# The output format is:
# <backtrace address> <function name> (<function address>)
