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

Daniel Grunwald	925a4e1e65	#2050 : Don't put ldflda/ldelema with immediate exceptions into StObj.TargetSlot. The C# translation of StObj will always apply delayed exceptions in these two cases, so putting an instruction with delayed exceptions in that slot would change program semantics.	6 years ago

Daniel Grunwald	f2151972a0	Redesign CompoundAssignmentInstruction to support an 'Address' mode where we don't implicitly turn an LdObj into an StObj, but instead directly operate on an address. This means we can get rid of the special case in TransformDisplayClassUsage, as compound.assign can now also be used with the address of a local variable.	7 years ago
