Test gcc.target/arm/pr42093.c, added by Ramana, requires support for arm_thumb2 but fails for those targets. The patch for which it was added modified support for thumb1. Should the test instead require arm_thumb1_ok, as in this patch?
No this is for a Thumb2 defect so the test is valid for Thumb2 - we shouldn't be generating a tbb / tbh with signed offsets and that's what was happening there.
This test I think ends up being fragile because the generation of tbb / tbh depends on how the blocks have been laid out . It would be interesting to try and get a test that works reliably in T2 .
cheers Ramana
