Siegfried Pammer	49bdca02d0	Fix #2032 : avoid propagating mutated SROA fields Aggressive scalar replacement propagated a display-class field to its source variable even when the field is mutated after initialization, aliasing two distinct source-level variables (Test9: thisField and this). Propagation is now cancelled when the field sees a second store or its address escapes, but only for propagation targets that cannot absorb the store: 'this' and variables that are themselves scalar-replaced display classes. Parameters continue to propagate, because their remaining uses are already restricted by ResolveVariableToPropagate and a captured parameter mutated inside a lambda (DelegateConstruction's Bug951) must keep mapping to the parameter. Checking CanPropagate first also keeps the guard away from Mono state-machine fields, whose VariableToDeclare is pre-bound to a state-machine variable that Propagate(null) would discard. Re-enables Test9 and adds Test10 covering the escaping-address variant (Interlocked.Exchange(ref displayClass.thisField, ...)).

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
