Siegfried Pammer	de33be74da	Don't reconstruct a partially written stackalloc as an initializer HandleSequentialLocAllocInitializer formed a stackalloc initializer whenever the explicit stores were contiguous from offset 0, even if they did not cover the whole buffer. A 'stackalloc byte[16]' reinterpreted as int and written through three of its four elements decompiled to 'stackalloc int[4] { 1, v, 3 }', whose initializer has fewer elements than the declared length and does not compile. Require every element to be written (from the constant data blob or an explicit store) before forming the initializer; otherwise the buffer stays a plain stackalloc with individual stores. Found while exploring stackalloc-initializer coverage. Assisted-by: Claude:claude-opus-4-8:Claude Code	2 weeks ago
Siegfried Pammer	a06c22b88a	Decode float/double stackalloc initializer constants by their type A constant-size stackalloc initializer stores its constant elements through a data blob (cpblk from a <PrivateImplementationDetails> field). ReadElement decoded every element by width, so a 4-byte float was read as Int32 and an 8-byte double as Int64. The resulting constant carried the raw bit pattern (1f decoded as 1.0653532E+09f) and its stack type no longer matched the store, tripping StObj.CheckInvariant. Dispatch on the element's type code so Single and Double are read as floating-point, matching the heap-array decoder. Found while exploring stackalloc-initializer coverage around the element-type hint fix; floating-point element types had no test case. Assisted-by: Claude:claude-opus-4-8:Claude Code	2 weeks ago

ElektroKill	760a6a653e	Reduce allocations in TransformArrayInitializers DecodeArrayInitializer - Instead of relying on the Add method of a list to expand the underlying array when necessary, the code now allocates a big enough array to fit all the elements removing the need for the Add method to expand the array several times. BlockFromInitializer now reuses a single instance of List<ILInstruction> instead of reallocating a new one every time and clears it when necessary. The same pre-allocation approach mentioned above has been implemented here too.	4 years ago

Daniel Grunwald	925a4e1e65	#2050 : Don't put ldflda/ldelema with immediate exceptions into StObj.TargetSlot.

Daniel Grunwald	469501210c	Add support for C# 7 tuple types: * Use tuple literals instead of calling 'new ValueTuple<..>' constructor * Where available, use element names for field access * Make CallBuilder aware of tuple-name/dynamic type erasure, to avoid introducing casts when the types differ only in the tuple element names. * Make CallBuilder provide a ResolveResult with the correct C# return type for the resulting expression. Previously we were using the type-erased return type from the IL. * Fix a bug that caused us to introduce returning casts when accessing an indexer.	8 years ago
