# test_zeroize.gdb
#
# This file is part of mbed TLS (https://tls.mbed.org)

#
# Purpose
#
# Run a test using the debugger to check that the mbedtls_zeroize() function in
# utils.h is not being optimized out by the compiler. To do so, the script
# loads the test program at programs/test/zeroize.c and sets a breakpoint at
# the last return statement in the main(). When the breakpoint is hit, the
# debugger manually checks the contents to be zeroized and checks that it is
# actually cleared.
#
# Note: This test requires that the test program is compiled with -g3.
