LLDB development
-- Debug lldb test cases on armhf to figure out problems in
individual test-cases
-- Create an updated lldb development project plan on JIRA.
-- Update collaborate with steps on LLDB development process.
== Progress ==
* Widening pass (TCWG-547) - 8/10
- Handled review comments.
- Improved CONVERT_EXPR handling.
- Re based and retested - found some failures.
- This was due to VRP reusing the range info computed in VRP1 after
type promotion is applied. Invalidating the range info when type is
promoted.
- ARM with type promotion now improves (-O2) about ~2.8% with one tiny
benchmark (where it used to regress).
- Still some test cases failures (not execution failures but scanning
certain patterns in the dump/asm).
* Misc - 2/10
- Connect slides.
- gcc-patches, gcc-bgs list
- Meetings
