Looking at this list here: http://www.sourceware.org/gdb/onlinedocs/gdb/Output-Formats.html

I don't see some of the ones you have on here. Do you have a reference document that specifies some of these?

[pieandcakes]

Thanks for the PR. Can you tell us which debugger version and distros you tried this on so that we can validate the testing matrix?

The problem with https://docs.microsoft.com/en-us/visualstudio/debugger/format-specifiers-in-cpp?view=vs-2019 is that it is specifically for the Visual Studio Debugger (cppvsdbg) and not for this. I don't mind it being added in this case but that document is targeting something else.

@WardenGnaw Assigning to you. I'm approving it but I'll leave it up to you to determine when to commit this change.

The reason for adding these is compatibility with natvis type definitions originally written for VS.
Like Qt visualizers for example.

bstr is different and not worth supported as BSTR is a Windows-only concept.

[Trass3r]

Done.

[WardenGnaw]

@Trass3r Thank you for your contirubtion to MIEngine!

We will target this for the next VSCode C++ Extension's insiders release.

It will appear in the CHANGELOG when it is avaliabe to use in the extension.

@WardenGnaw I still don't see it in the changelog. So I guess it hasn't been integrated yet?

[WardenGnaw]

I must have missed this one when updating the change log.
Do you not see the change in the latest cpptools extension?
