Siegfried Pammer	154d60e2a3	TransformExpressionTrees: document the ILAst patterns Every converter now states the Expression.* call it matches and the ILAst it produces, and the argument-count switches label the factory overload each case stands for. The shapes were read off ILAst dumps of compiled expression trees rather than from the factory signatures; two branches are documented as unreachable, since no arithmetic or logical factory declares the four-argument (left, right, liftToNull, method) overload their case matches. Also drops the result-type local left in ConvertField, which BuildField re-derives from the field and the type hint. Assisted-by: Claude:claude-opus-5[1m]:Claude Code	2 weeks ago
Siegfried Pammer	49b7257e9c	TransformExpressionTrees: inline MatchConstantCall into ConvertConstant ConvertConstant is its only caller, and with the result type gone the out parameter that reconstructed it - a switch over LdNull/LdStr/Ldc* - has no consumer. What remains is a match condition: the two-argument Expression.Constant overload must pass its type as typeof(T), while the one-argument overload legacy csc emits for display-class instances has nothing to check.

Siegfried Pammer	d9b502aa20	TransformExpressionTrees: return only the builder, not the result type Every converter handed back a (Func<ILInstruction>, IType) pair, and the IType was consumed by matchers that ran before the builder. Now that the ILAst instructions carry their own types, InferType() on the built operand answers the same questions, so the type-dependent decisions move into the builders and the pair collapses to the builder alone. Builders that could already fail (ConvertArrayIndex) set the precedent for returning null from inside one; ConvertInstruction propagates that.

Siegfried Pammer	a3b06e79fe	TransformExpressionTrees: drop the unused result type from ConvertBind ConvertBind is the only expression-tree converter whose IType nobody reads: ConvertMemberInit, its sole caller, takes Item1 and discards the rest, and the member type is recoverable from the Call/StObj it builds anyway.

Siegfried Pammer	80b901ee2e	TransformExpressionTrees: operatorName for ConvertBinaryNumericOperator System.Linq.Expressions resolves the user-defined operator behind a binary factory by metadata name (Expression.Add looks up op_Addition), and the checked factories reuse the unchecked names: AddChecked also looks up op_Addition, never op_CheckedAddition. Recording that name at the call site keeps the mapping next to the factory it belongs to. Assisted-by: Claude:claude-opus-5[1m]:Claude Code	2 weeks ago

Daniel Grunwald	c4e181505c	Prepare for a split of StackType.O into StackType.Obj and StackType.VT: the easy cases	2 weeks ago
Daniel Grunwald	5526400b17	Extend InferType() to every ILInstruction Change InferType() to an abstract method and implement for every ILInstruction. With this change, we now always have enough information to create a variable of an appropriate type to store the result of evaluating the instruction. This previously was not the case for instructions producing "other value type", for which the stacktype-based fallback incorrectly produced `object`.	2 weeks 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

Siegfried Pammer	7e1e9d65fd	Fix #2922 : Invalid object initializer ILAst, when expression tree contains get-accessor in Expression.Bind. Because either one of the accessors is used by Expression.Bind to determine the property, we can safely use the set-accessor instead.	4 years ago
