# Test gdbstub Xfer:siginfo:read stub.
#
# The test runs a binary that causes a SIGSEGV and then looks for additional
# info about the signal through printing GDB's '$_siginfo' special variable,
# which sends a Xfer:siginfo:read query to the gdbstub.
#
# The binary causes a SIGSEGV at dereferencing a pointer with value 0xdeadbeef,
# so the test looks for and checks if this address is correctly reported by the
# gdbstub.
#
# This is launched via tests/guest-debug/run-test.py
