I just published a new project in GitHub called WebView4Delphi. WebView4Delphi allows you to embed Chromium based web browsers in your Delphi or Lazarus applications using the WebView2 runtime. It uses the latest stable version of the WebView2 nuget package 1.0.1054.31. I used many of the tricks I learned creating CEF4Delphi and you will notice many similarities if you used it. I still have to write the documentation but you can build the available demos to see it working in VCL, FMX and Lazarus apps. There are a few things pending like the "windowless mode". It's being distributed with a simple MIT license so anyone can do whatever s/he wants with it. https://github.com/salvadordf/WebView4Delphi

What's new video: Demos used in video: Map Viewer (OpenGL canvas., SVG, PDF, etc) https://delphihtmlcomponents.com/MapView.zip Fast blur: https://delphihtmlcomponents.com/blur.zip HTML Editor (VCL), print preview window https://delphihtmlcomponents.com/htedit.zip Office file viewer and print preview window https://delphihtmlcomponents.com/FileBrowser.zip What's new: Core Precise text rendering and measurement for all windows canvases: now text has the same layouot in GDI, GDI+, DX and Skia canvases on screen and printer and doesn't depend on scaling. Skia canvas for VCL. PDF export using Skia canvas - works from any canvas, not only Skia OpenGL canvas - useful for fast rendering of very large SVG (don't use as default canvas - it requires window handle). GDI canvas: improved graphics rendering speed. CSS var() support. function htmlpars.GetHTMLEncoding - determine codepage of HTML (TBytes). function for converting stylesheet to dark theme - TCSSStyleSheet.LighttoDark Support for UTF8 encoded inline SVG images. Optimized SVG paths seialization (smaller size) Optimized drawing of large SVG Support for individual glyph positioning in SVG text (DX attribute). THtCustomPath: CurveTo record now do not have initial point, all curves are defined by 3 points. HtPanel/Editor: support for horizontal mouse wheel HtPanel/Editor: Smooth scrolling in both direction HtPanel/Editor: Fast zoom in / zoom out in OpenGL canvas. Library now contains fastest native blur implementation (10-50 times faster than other). See htcanvas.FastBlur() Fast Base64Encode function (5-10 times faster than standard): htutils.Base64EncodeNoLF() THtBitmapData bitness conversion and masking methods are optimized using SIMD, f.e. Convert24to32. TSVGElement has GetStats methods for retrieving number of primitives, points, etc. Added support for system colors from CSS 4 color module: canvas, canvastext, field, fieldtext, etc. Bitmap images are now supported in GDI+, DX and Skia canvases. FontAwesome is upgraded to version 6.4. Now it contains regular (fa) and solid (fa-solid) icons. Support for CSS variables. Optimized displaying of documents containing many SVG images - like converted PDF documents (2000+ pages). Support for outlined and filled text (SVG). Support for relative image paths ('.\..') Improved flexbox layout. THtImageConverter now have CanvasClass propery - used in HTMLtoPNG conversion. HtPanel: OnScroll event New core classes documentation - /docs/HTML Library.chm/pdf https://delphihtmlcomponents.com/help/ New demos - MapView, Blur, Skia Editor Words suggestions/prediction while typing - see Words prediction section in Editor manual. New icons in context toolbar. Context and selection toolbars has acrylic background. All toolbars (selection, spellcheck) can be closed by pressing Esc. Add/edit image button in context toolbar Copy image button in selection toolbar Print preview button in context toolbar Add Symbol button in context toolbar. Spellcheck button in context toolbar. Windows ISpell implementation - htspellwin unit. Simply add it to uses list for spellcheking and word correction. Inline word correction - click on misspelled word to see suggestions. Windows spellecher is also used for autocorrection, suggection selection is based on Levenshtein distance. Cancelled autocorrections are remembered - words are added to exceptions list. Inline image cropping - use shift + resize handles Reports and Scripts New preview window for VCL and FMX (OSX, Linux) - float toolbar, smooth scroll and zoom, page selection and reorder, text search, text editing and moving. Preview window store its maximized/normal state and position for normal state even when maximized. Support for var parameters of all types. Fixed repeat - until bug. Default indexed properties now workind for object proprties, f.e. property Strings: TStringList; Obj.Strings := 'test'; Script can have own debugger instance

It took me a bit longer than expected to get here but I believe I've finally reached the goal. The following shows VTune profiling a Delphi application, with symbol, line number and source code resolution: Download Get the source here: https://bitbucket.org/anders_melander/map2pdb/ And a precompiled exe here: https://bitbucket.org/anders_melander/map2pdb/downloads/ The source has only been tested with Delphi 10.3 - uses inline vars so it will not compile with older versions. Usage map2pdb - Copyright (c) 2021 Anders Melander Version 2.0 Parses the map file produced by Delphi and writes a PDB file. Usage: map2pdb [options] <map-filename> Options: -v Verbose output -pdb[:<output-filename>] Writes a PDB (default) -yaml[:<output-filename>] Writes an YAML file that can be used with llvm-pdbutil -bind[:<exe-filename>] Patches a Delphi compiled exe file to include a reference to the pdb file -test Works on test data. Ignores the input file Example: Configure your project linker options to output a Detailed map file. Compile the project. Execute map2pdb <map-filename> -bind Profile the application with VTune (or whatever) Known issues The -bind switch must occur after the filename contrary to the usage instructions. PDB files larger than 16Mb are not valid. This is currently by design. 64-bit PE files are not yet supported by the -bind option. As should be evident I decided not to go the DWARF route after all. After using a few days to read the DWARF specification and examine the FPC source I decided that it would be easier to leverage the PDB knowledge I had already acquired. Not that this has been easy. Even though I've been able to use the LLVM PDB implementation and Microsoft's PDB source as a reference LLVM's implementation is incomplete and buggy and the LLVM source is "modern C++" which means that it's close to unreadable in places. Microsoft's source, while written in clean C and guaranteed to be correct, doesn't compile and is poorly commented. Luckily it was nothing a few all-nighters with a disassembler and a hex editor couldn't solve. Enjoy!

It's a sign from above

You can create a report at https://quality.embarcadero.com

The help also says it is generated if either option is set (detailed map files OR .drc generation); Package Files Created by Compiling - RAD Studio (embarcadero.com)

Looks like as designed:

With 11.3 it's the same. The .drc file is generated anyway.

Thankfully, my days of working for large corporations with their policies aimed at micromanaging programmer activities are over. I don't have an issue with Traceability. What i have an issue with is when you're working for a company and they put you through a few days of formal training in something like Agile that goes through things in detail, then you get back to your project and are told things aren't really the way you were taught. Such as, while Development owns the Backlog, Developers aren't allowed to write up Change Tickets or submit anything into the Backlog, only the Client is, and that requires a detailed documentation of the errors and how to reproduce them. Which is fine unless the errors are not reproducible because of existing bugs that the Client won't ever see, but Devs can and do find them. We're hired as "experts" and then managed like monkeys. I'm done with it. Got my own stuff to play with now. 🙂

If you have an active ssubscription just create a support case (https://supportforms.embarcadero.com/ if memory serves).

Oh, darn. I'm just lucky nobody depends on my numbers then...

Profilers measure application execution. Two main types are Sampling and Instrumenting profilers. You run the application and the profiler measures times for code to complete. It sounds like what you want is some sort of AI to read/parse your code and suggest improvements. You could try feeding pieces to ChatGPT and see how well that performs... Or, perhaps you want a static code analyzer, like Pascal Analyzer from Peganza....https://www.peganza.com/products_pal.html it will parse your code and provide reports of things that could be improved. (They offer a free, limited feature version to try....Pascal Analyzer Lite: https://www.peganza.com/download.html)

Not quite Game Over it seems. It appears that the Size being 1 is just because whomever wrote the linker has misunderstood the meaning of the field. 1 in this case means that there one entry, so I could replace the 1 with $1C and the entry would be valid. If I then assume that data in the debug directory is now valid then the one entry points to the .debug segment. I assume this segment contains the TDS debug data or something like (it starts with the TDS signature "FB09"). It's only present (for both 32- and 64-bit) if I link with debug info enabled. Now since this debug info isn't used anyway when profiling with VTune, I can just hijack the area occupied by it and store my IMAGE_DEBUG_TYPE_CODEVIEW structure there. This means that I won't have to deal with adding new sections and updating all the various offsets in the PE header. Should be doable with what I know so far. I have to some gardening to take care of now but I'll give it another go this evening. Stay (V)tuned...
