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	6 days ago
Siegfried Pammer	d4922cfec0	Don't inline a pointer-typed stackalloc into an expression A stackalloc whose result is a pointer is only valid C# as the initializer of a pointer-typed local. The inliner moved a single-use pointer stackalloc into its use, producing e.g. 'K.V(stackalloc int[3] { 1, 2, v })' or '*stackalloc ...'; in an expression position the stackalloc is typed as Span<T>, which does not convert to a pointer, so the output did not compile. Keep such a stackalloc as a separate local. Moving it into a local store (its declaration) and into the Span<T>/ReadOnlySpan<T> constructor stay allowed, since those are the positions where the pointer or span form is exactly what is wanted. Found while exploring stackalloc-initializer coverage. Assisted-by: Claude:claude-opus-4-8:Claude Code	2 weeks ago

Daniel Grunwald	dd4bf7d8a4	Fix #3518 by replacing `FixLoneIsInst` with an inlining restriction. This way we avoid having to extract later, as we will never inline if the `isinst` argument if this could result in it being unrepresentable in C#. This commit also refactors inlining restrictions to avoid requiring special cases in ILInlining itself. But when making this change, I discovered that this broke our pattern-matching tests, and that the weird IL with double `isinst` is indeed generated by the C# compiler for `if (genericParam is StringComparison.Ordinal)` style code. So instead we also allow `isinst` with a `box(expr-without-side-effects)` argument to be represented with the `expr is T ? (T)expr : null` emulation.	11 months ago
