You can reproduce exactly what is being done by the CI by following:
https://git-us.linaro.org/toolchain/ci/interesting-commits.git/plain/gcc/sh=
a1/7ca35f2e430081d6ec91e910002f92d9713350fa/tcwg_gnu_embed_check_gcc/master=
-thumb_m55_hard_eabi/reproduction_instructions.txt

If you prefer to do it manually:
