# Purpose
|
||
|
|
#
|
||
|
|
# Show symbols in the X.509 and TLS libraries that are defined in another
|
||
|
|
# libmbedtlsXXX.a library. This is usually done to list Crypto dependencies.
|
||
|
|
#
|
||
|
|
# Usage:
|
||
|
|
# - build the library with debug symbols and the config you're interested in
|
||
|
|
# (default, full minus MBEDTLS_USE_PSA_CRYPTO, full, etc.)
|
||
|
|
# - run this script with the name of your config as the only argument
|
