Only effective together with --rom, makes two changes: - abort in case of build warnings - skip writing statistics The goal is to make sure we build cleanly in the configuration used for measuring code size, with all the compilers we use, both because we care about that configuration and those compilers, and because any warnings would cast a shadow on the code size measurements. Currently the build fails with armc5 due to a pre-existing warning in PK, this will be fixed in the next commit. The next commit will also add an all.sh component to make sure we have no regression in the future. (Which is the motivation for --check skipping statistics: an all.sh component should probably not leave files around.) While at it, fix two things: 1. The call to gcc --version was redundant with the echo line below 2. WARNING_CFLAGS shouldn't be overriden with armclang, as it would remove the -Wall -Wextra and any directory-specific warning (such as -Wdeclaration-after-statement in library). It's meant to be overriden only with compilers that don't accept the default value (namely armc5 here).

# Purpose
|
|
#
|
|
# * Create a baremetal library-only build (omitting the tests and
|
|
# example programs, which have stronger configuration requirements)
|
|
# for a Cortex-M target in a minimal configuration, and generate
|
|
# code-size statistics.
|
|
# By default, the script uses configs/baremetal.h and targets Cortex-M0+,
|
|
# and outputs the code-size statistics as `rom.COMMIT_HASH`.
|
|
#
|
|
# * Create a 32-bit host-build of library, tests and example programs
|
|
# in a 'baremetal' base configuration minimally modified to allow
|
|
# running tests and example programs, and obtain heap usage statistics
|
|
# of a test run of ssl_client2 and ssl_server2. This can be used as
|
|
# an estimate for heap usage of 32-bit baremetal applications using Mbed TLS.
|
|
#
|
|
# By default, the script uses configs/baremetal.h as the base configuration
|
|
# modified by configs/baremetal_test.h, and emits the heap usage statistics
|
|
# as `massif.COMMIT_HASH`.
|
