Hi,
This backport intends to enable new arm rtx cost model in trunk for
embedded-4_8-branch. The backport incorporates all relevant trunk commits
and some minor tweaks for embedded-4_8-branch. Tested with gcc regression
test and found one regression related to case pr42575.c. The upstream gcc
has same issue. We are working on it.
BR,
Terry
