It also excludes debugging features that increase the code size -# of other modules. -# Features that are excluded from "full" won't be in "baremetal" either. - -use warnings; -use strict; - -my $config_file = "include/mbedtls/config.h"; -my $usage = <<EOU; -$0 [-f <file> | --file <file>] [-o | --force] - [set <symbol> <value> | unset <symbol> | get <symbol> | - full | realfull | baremetal] - -Commands - set <symbol> [<value>] - Uncomments or adds a #define for the <symbol> to - the configuration file, and optionally making it - of <value>. - If the symbol isn't present in the file an error - is returned. - unset <symbol> - Comments out the #define for the given symbol if - present in the configuration file. - get <symbol> - Finds the #define for the given symbol, returning - an exitcode of 0 if the symbol is found, and 1 if - not.
