| − | ** No longer planned for Kepler
| |
| − | * Expression working sets [https://bugs.eclipse.org/372181 372181]
| |
| − | ** Pawel re-factored patch
| |
| − | ** After review there were many comments from platform that is delaying adoption
| |
| − | ** People interested must answer comments to try to move this forward
| |
| − | ** Can enhanced expressions be used for these use cases?
| |
| − | *** Abeer will follow-up on this with his product people.
| |
| − | *** Marc to look at Pawel's CDT fix for expression working sets to try it with Enhanced Expressions. Persistence of the collapsed state should work with this patch.
| |
| − | * Step into Selection [https://bugs.eclipse.org/244865 Bug 244865]
| |
| − | ** Alvaro is implementing this feature
| |
| − | ** First version will deal with the most common and simplest cases
| |
| − | * Dynamic-printf [https://bugs.eclipse.org/400628 Bug 400628]
| |
| − | ** Support for "Add breakpoint..." command for dprintf. First step is to support if for tracepoints [https://bugs.eclipse.org/376116 Bug 376116]
| |
| − | * Hardware breakpoints [https://bugs.eclipse.org/332993 Bug 332993]
| |
| − | ** We mentioned we could use a breakpoint type for hardware breakpoint and temporary bp
| |
| − | ** We could do the same for Tracepoints, but since tracepoints are a top-level breakpoint and not an attribute of a C/C++ breakpoint, this would need a lot of work. Also, the property page for tracepoint is different because it has a passcount and no ignore count.
| |
| − | ** How should dynamic printf be implemented? As a top-level bp like tracepoints, or as an attribute of breakpoints? For reference, WindRiver had their implementation use a top-level breakpoint.
| |
| − | ** GDB has a setting to tell GDB to set a hardware breakpoint if it can and if not then set a software breakpoint. This should be considered when dealing with hardware breakpoint support

| |
| − | * A extra conference call will be scheduled February 19th to discuss features for the Multicore Visualizer. All are welcomed to call in. Info will be posted on the list.
| |
| − | * Pin&Clone in platform [https://bugs.eclipse.org/145635 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 [https://bugs.eclipse.org/391608 Bug 391608]
| |
| − | ** All changes will be made in Linux Tools project, no need to change CDT
| |
| − | * CPU usage shown in Multicore Visualizer [https://bugs.eclipse.org/396268 Bug 396268]
| |
| − | * GDB Console synchronization
| |
| − | ** Memory changes synched with CDT [https://bugs.eclipse.org/397715 Bug 397715]
| |
| − | ** Reverse debugging enabled synched with CDT [https://bugs.eclipse.org/399163 Bug 399163]
| |
| − | ** Other new notifications planned such as: =traceframe-changed
| |
| − | * Expression working sets [https://bugs.eclipse.org/372181 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 [https://bugs.eclipse.org/244865 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 [https://bugs.eclipse.org/332993 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

| + | ** VarObjects for Registers would be interesting. |
| − | ** Terminate and restart should keep the Pin&Clone with this CDT patch | + | ** If time allows, Mikhail may have a look again. |
| − | ** Feature can be tested in a branch in the platform repo | + | * All Debug JUnit tests running on HIPP using all of GDB >= 7.1 |

| − | * Extend CDT launch to allow external profiling [https://bugs.eclipse.org/391608 Bug 391608]
| + | ** In some cases, probably with more recent GCCs, GDB 7.0 cannot step over printf (and maybe other issues) |
| − | ** To see profiling buttons one must Customize Perspective and enable the "Profile" menu | + | ** We discussed and approved only supporting GDB 7.1 and higher |
| − | ** Profile configuration add a single Profile tab which give the user the possibility to choose between different available profile. | + | ** We won't remove the code supporting older GDBs but we won't work on making those work |
| − | ** Profile As... will now only show "Local C/C++ Application" and will default to the highest ranked available profiler | + | ** We will announce in N&N and make it part of the 8.6 review record |
