Hi Guys,
The new MSP430 target has a few limitations which show up as
unexpected failures in the GCC testsuite. I would like to apply the
patch below to update target-supports.exp with this information.
Applying the patch results in a drop of 133 unexpected failures (per
multilib).
OK to apply ?
Cheers
Nick
