Minutes

• A extra conference call will be scheduled February 19th to discuss features for the Multicore Visualizer. All all welcome to call it. Info will be posted on the list.
• Pin&Clone in platform Bug 145635
  • Pawel will continue working on it
  • Plan is to make Pin&Clone a single action
  • Would be nice if people gave feeback on the branch which has this new way of handling things
• Extend CDT launch to allow external profiling Bug 391608
  • All changes will be made in Linux Tools project, no need to change CDT
• CPU usage shown in Multicore Visualizer Bug 396268
• GDB Console synchronization
  • Memory changes synched with CDT Bug 397715
  • Reverse debugging enabled synched with CDT Bug 399163
  • Other new notifications planned such as: =traceframe-changed
• Expression working sets 372181
  • Pawel put Abeer's patch and put it on a branch with a bit of refactoring.
  • Pawel is playing around with automatic selection of working sets
  • If Pawel does not have enough time to continue playing around with it he will commit the feature as Abeer implemented it
  • Automatic selection would be nice and Abeer is also looking into it
  • Abeer will continue to work on it and post information on the bug
• StepIntoSelection is being implemented for CDT Bug 244865
• Marc K would like to try to add Dynamic printf to CDT
  • Breakpoint types would be used to provide this
  • The new bp type would be kept in DSF-GDB
• Hardware breakpoint contribution Bug 332993
  • Mikhail is concerned that changing the breakpoint type to set a hardware bp is overkill
  • Another option would be to add a "Toggle Hardware Breakpoint" command, although that is not ideal either
  • We would like to provide this feature in CDT, and Mikhail might be able to post a patch

Minutes

• Assembly view vs Disassembly view
  • Want to show assembly with source code without the use of the Debugger
  • How does CDT get access to the assembly code
  • A dummy debug session hidden from the user can be used to fill the disassembly view
  • Jeff will open bug
• Pin&Clone in platform Bug 145635
  • Update for CDT to remove Pin&Clone buttons: Bug 398012
  • Terminate and restart should keep the Pin&Clone with this CDT patch
  • Feature can be tested in a branch in the platform repo
  • Would allow to use another 'agent' to provide info without a debugger
  • Adds breadcrumb to the view when pinned
  • No colors and no visual decorator in the Debug view, as CDT used to do
• Extend CDT launch to allow external profiling Bug 391608
  • To see profiling buttons one must Customize Perspective and enable the "Profile" menu
  • Profile configuration add a single Profile tab which give the user the possibility to choose between different available profile.
  • Profile As... will now only show "Local C/C++ Application" and will default to the highest ranked available profiler
  • If no profiler is installed the profiling launch will show an error.
• CPU usage shown in Multicore Visualizer Bug 396268
  • Good progress, expect to push code next week
• Expression working sets 372181
  • Abeer will comment on bug
  • Pawel will look at it once Pin&clone is ok
• GDB Console synchronization
  • Mikhail did the synchronization of breakpoints. This needs GDB 7.4
  • GDB 7.6 will provide new MI notifications when data changes.
  • Marc K has pushed a feature for review, which uses the new =memory-changed event Bug 397715
  • Marc K plans on making use of other new notifications such as: =traceframe-changed, =record-started, =record-stopped
