Hi,
This patch set tries to reduce the number of failed test cases for ARM based targets by leveraging the -mcpu=unset/-march=unset feature introduced in r15-3606-g7d6c6a0d15c. With the patch set applied, the test cases listed below will be reported as "regressions", but it's really that the test cases needs to be adapted to the different context they might be tested in. I have checked for regressions with r15-5047-g7e1d9f58858 as a baseline for Cortex-A7, Cortex-M0/3/4/7/33/55/85. For some of the regressions listed below, there is either patches shared that should fix them, or discussion has started on how to address them.
