Description

I closed all Debugger views: Variables, Stack and Watch is empty and closed as well. Still very slow I can send slow_steps.log if needed. The problem is with our "-stack-list-arguments 1" request per step. I modified it a little (see patch) and now debugger is instant like in command line Created attachment 163690 [details]

slow steps log
The proposal is to introduce combo-box in Tools->Options->C++->Debugger: - use 0 as a default, but allow use to select view mode for 0,1,2 from doc: https://sourceware.org/gdb/onlinedocs/gdb/GDB_002fMI-Stack-Manipulation.html If print-values is 0 or --no-values, print only the names of the variables; if it is 1 or --all-values, print also their values; and if it is 2 or --simple-values, print the name, type and value for simple data types, and the name and type for arrays, structures and unions. If the option --no-frame-filters is supplied, then Python frame filters will not be executed. Btw, I have tried "2" and it as slow as "1" when debug clang, but may be for normal binaries it wouldn't so slow. That's why may be 2 is more friendly that 0, but I still need a way to set to '0' for my usecase New check box added into Tools-> Options -> C/C++-> Debugging You can turn off arguments values request for Cal Stack and Debugging View Even if it is turned on but Call Stack View and Debugging view are both closed Step will work fast. suggested patch is in attach Created attachment 163730 [details]
