Siegfried Pammer	cd212ea05f	Pass the compilation to ILInstruction.CheckInvariant Invariants that involve types (stack type of a variable against its IType, the element type of an array access, the operand types of a comparison) need a type system to resolve them against, and the only correct one is the type system the instruction tree was decoded with. Until now CheckInvariant took only the phase, so such a check had no compilation to use: DeconstructInstruction.CheckInvariant called IsAssignment with a null type system, which only held up because the targets it sees are ldloc, whose InferType never touches the compilation; a ldflda-wrapped or pointer target would have failed inside the invariant instead of reporting a violation. Every call site already has that type system in scope: the ILReader's compilation, the ILTransformContext of the running transform, or the decompiler's own IDecompilerTypeSystem. It is now passed explicitly and the base implementation asserts it is present, so a future invariant can rely on it without re-plumbing the callers.

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

Daniel Grunwald	8117dfff4a	Fix #1242 : Discard unreachable code. Unreachable code is not part of the dominator tree, which most of our transforms are based on. In particular, dominance-based loop detection runs into the problem where unreachable code might have jumps into two independent loops. In that case, it's impossible to place the unreachable code in a way that avoids assertions / generating invalid C#. We establish the invariant that all blocks in a BlockContainer must be statically reachable from the entry point (-> every block is part of the dominator tree). This means transforms no longer have to deal with special cases for unreachable code. The "Remove dead and side effect free code" option still has an effect on dead stores, but unreachable code is now always removed (previously this also was dependent on this option).	7 years ago

Daniel Grunwald	102729cfde	Put switch instructions into their own BlockContainer. This removes the need for "goto case" in the ILAst as we can just branch to the appropriate block. It also means we can support "break;" within switch using the "leave" instruction (otherwise we'd have to introduce yet another special kind of jump).	9 years ago
