cpu/msp430: update to modern gcc & newlib
2019-02-22 23:42:08 +01:00
# Target architecture for the build. Use msp430-elf if you are unsure.
build system: Overwrite TARGET_ARCH per arch Add `TARGET_ARCH_<ARCH>` for each architecture (e.g. `TARGET_ARCH_CORTEX` for Cortex M) to allow users to overwrite the target triple for a specific arch from ~/.profile or ~/.bashrc (or the like) without overwriting it for all others as well.

makefiles: do not locally export compilation variables These are already exported by `makefiles/vars.inc.mk`. It is a prerequisite to allow handling compilation without global exports.

toolchain/cflags: enable dwarf compression. Use the -gz option to compress ELF sections containing DWARF information. This saves around 50% of disk space, without any side effects. See https://gcc.gnu.org/onlinedocs/gcc-9.2.0/gcc/Debugging-Options.html#Debugging-Options for more infomation on this option. Some platforms have an outdated toolchain that does not support -gz so the flag is blacklisted there. Even then, the results are quite impressive. I used @cladmi's `buildtest` branch (https://github.com/cladmi/RIOT/tree/wip/du/buildtest) with this change and compiled the `examples/default` application: ``` $ BUILD_IN_DOCKER=1 DOCKER="sudo docker" make -C examples/default buildtest-indocker ``` The size was obtained with: ``` $ find output -name "*.bin.bindirsize" -type f -exec tail -n1 '{}' \; | cut -f 1 | awk '{s+=$1} END {printf "%.0f", s}' ``` Results: - Vanilla: 10328112 KB (~10GB). - with -gz: 4982788 KB (~5GB). This was inspired by #8496.
