Debugger unable to view large structs

Martin.S

Hello,

I am using ARM Development Studio for debugging and have encountered some problems with the debugger's handling of large c structs.

EDIT: The following part about size is unrelated to the bug and I misread the numbers (see first Answer to this post).

In the variables view it shows the following for my struct vm: 

However, the actual size of struct vm is 76256 (I added a print to get sizeof(struct vm)) and I am unable to access fields of the struct that are outside of the size shown in the Variables view.

Even when using the debugger commands to print vms[0].something it fails with ERROR(EXP16): Member "something" not found despite something being a member of the struct.

Is there a way to view larger structs with the ARM Debugger?

I am thankful for any help!

Greetings

Martin.S

    Hi Stephen,

    Sorry that I didn't reply earlier. First off, unticking "Use LLVM Dwarf Parser" indeed fixed the bug and now I am able to see all struct members!
    Great to hear that you could reproduce the error and are working on a fix.

    About the size in my original post, I somehow misread the numbers and thought the size shown in ARM DS was smaller than the actual size in bytes.

    I did not encounter members shown as "Optimized Away" (apart from occasions where I assume they acutally were optimized).

    Thanks for your fast help and the workaround.

    Kind Regards

    Martin
