What does $qqro means appended after methodname in stacktrace of Delhi application

Question

I have a created a stacktrace dump, using JCLDebug unit. Can anybody tell me what the $qqro means, appended to the method name CheckValidDate?

sToolEdit.TsCustomDateEdit.CheckValidDate$qqro (Line 926, "sToolEdit.pas" + 33) [00943068] sToolEdit.TsCustomDateEdit.CMExit$qqrr27Winapi.Messages.TWMNoParams (Line 960, "sToolEdit.pas" + 1) [0055C3ED] Vcl.Controls.TControl.WndProc$qqrr24Winapi.Messages.TMessage (Line 7224, "Vcl.Controls.pas" + 91) [0057FE70] Vcl.StdCtrls.Stdctrls.TButtonControl.WndProc$qqrr24Winapi.Messages.TMessage

(the above quote is only a clipped part of the whole stacktrace)

Those are mangled names. The annotation of the name encodes the parameter lists and is used to disambiguate overloaded methods in runtime packages.

The is some useful information here: Delphi - unmangle names in BPL's

So `qqro` means: `register calling convention, boolean`. etc. – Rudy Velthuis May 22 '17 at 11:15
