Christoph Wille	c8474419c4	Redesign DecompilerEventSource with Start/Stop tracing and keyword gating The events introduced in #2519 timed only the five per-entity DoDecompile overloads, allocated a Stopwatch and the member's FullName even when no trace session was attached, and reported whole milliseconds, which rounds almost every member to zero. Flat one-shot events also gave PerfView and dotnet-trace no way to show durations or nesting, and the actually expensive stages (type system initialization, assembly resolution probing, the IL/AST transform pipelines, whole-project decompilation) were not instrumented at all. Start/Stop event pairs let trace viewers derive duration and nesting from event timestamps, keywords let a session enable only the areas of interest, and every call site is gated on IsEnabled() so tracing costs a branch when disabled. Per-transform events are Verbose because of their volume; unlike the STEP/Stepper mechanism they work in Release builds. EventSource is in-box for netstandard2.0 and flows over both ETW and EventPipe, so this stays cross-platform with no new dependency. Assisted-by: Claude:claude-fable-5:Claude Code	2 months ago
Siegfried Pammer	468e3da92c	Bracket ILAst WriteTo in one place via WriteToCore The debug-step node bracket (MarkNodeStart/try/finally/MarkNodeEnd) was copied into every hand-written WriteTo override and re-emitted by the T4 generator, so a newly added instruction could silently omit it and lose step highlighting with no compile error or test failure. Seal WriteTo on ILInstruction to apply the bracket once and delegate to a new abstract WriteToCore; move every override (hand-written and generated) to WriteToCore without the wrapper. Rendered output is unchanged -- the marks are no-ops unless the output tracks nodes. Assisted-by: Claude:claude-opus-4-8:Claude Code	3 months ago
Siegfried Pammer	04505bbdf2	Highlight and scroll to the changed instruction in the ILAst view The C# debug-steps view highlights and centers the exact AST node a transform changed; the ILAst view already had the step tree and replay-at-step but produced no highlight. Bring it to parity. IL rendering has no token-writer seam like the C# output visitor, so per-instruction text spans are recorded by bracketing ILInstruction.WriteTo via a new INodeTrackingOutput. The dominant inst.ReplaceWith(newInst) transform pattern detaches the instruction passed to Step, so ILTransformContext gains EndStep to record the produced instruction; Stepper additionally records the position's ancestor chain as fallback candidates before the step-limit throw, so the "show state before" view -- which halts at the selected step -- still resolves to a surviving ancestor (ultimately the ILFunction). The highlight-range resolver is shared with the C# language. Assisted-by: Claude:claude-opus-4-8:Claude Code	3 months ago

Jackson Davis	6ab1f98fa3	Expand the range of sequence points out the closest empty ilstack or implicit sequence point without creating overlapping sequence points. If such a location cannot be found do, nothing. Fill in the gaps with hidden sequence points. Also emit a sequence point for the prolog to account for seqeunce point there emitted by the C# compiler. Without this, the debugger can stop there on a step in using the original pdb, then decompile resulting in a no-code at this location failure.	7 years ago
