This series adds test cases for linked {break,watch}points to the
debug-exceptions test, and expands {break,watch}point tests to
use non-zero {break,watch}points (the current test always uses
{break,watch}point#0).
Patches 1-6 add some helpers or do minor refactoring for
preparation of adding test cases in subsequent patches.
Patches 7-8 add test cases for a linked {break,watch}point.
Patch 9 expands {break,watch}point test cases to use non-zero
{break,watch}points.
The series is based on v6.1-rc1 with the patch [1] applied.
v2:
- Use FIELD_GET() to extract ID register fields (Oliver, Ricardo)
- Try to make function/variable names more clear (Oliver, Ricardo)
- Make the context number more unlikely to happen by mistake (Ricardo)
- Remove unnecessary GUEST_SYNC for test stage tracking
- Collect Reviewed-bys from Oliver and Ricardo (thanks!)
