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
Daniel Grunwald	38e7ab4373	Fix #3110 : Add support for MCS 2.6.4 pinned region with array variable * Added additional code to remove the conv instruction present in the initialization part of the pinned region. * Extended the code responsible for removing the unpin stloc to correctly match the inverted condition found in MCS 2.6.4 compiled code. * Enabled already present correctness test to run for MCS 2.6.4. This is a more generalized version of the fix on PR #3110 proposed by @ElektroKill.	2 years ago
ElektroKill	915c0310c4	Add support for MSC 2.6.4 pinned region with string variable	3 years ago
Siegfried Pammer	3c2e52854e	DetectPinnedRegions: Inline the stack-slot involved in CustomRefPinPattern so that the following ProcessPinnedRegion call can reuse existing unmanaged pointer variables instead of being forced to create a new variable.	5 years ago
Siegfried Pammer	f98012ec16	DetectPinnedRegions: Support special case where pinned pointer is unused and the compiler optimized out the StopGCTracking-conversion.	5 years ago
Daniel Grunwald	df339e72fb	Fix DetectPinnedRegions.SplitBlocksAtWritesToPinnedLocals creating blocks without ILRange. These blocks could trigger assertions if LoopDetection was creating a loop BlockContainer from them (BlockContainers have an assertion requiring an ILRange). Closes #2533 and #2457.	5 years ago
Daniel Grunwald	583771e012	#2533 : Fix bug in CreatePinnedRegion that could cause pinned regions to be created with the wrong entry point if the original IL had blocks in an unusual order	5 years ago
Daniel Grunwald	eec24ee6bb	Fix #2311 : Handle additional `comp` instruction in `IsNullSafeArrayToPointerNotNullBlock`	6 years ago
Daniel Grunwald	0e1c24464f	Fix #2148 : Don't attempt to detect `fixed` statement for pinned value types	6 years ago
dotnet format	0d9f871a4f	#2128 : Reformat the whole code base.	6 years ago
Daniel Grunwald	f5409ebe31	Fix re-pinning getting confused about which variant of the pinned local to use when the new re-pinned reference depends on the old pinned reference.	6 years ago
Daniel Grunwald	4b716e2db5	Fix #2056 : "remove branch into body" must be executed before the clone cleanup Otherwise the to-be-removed branch could keep an soon-to-be-unreachable block alive outside the pinned region.	6 years ago
Daniel Grunwald	bd4e565b93	Ensure all pinned regions variables are converted to VariableKind.PinnedRegionLocal	6 years ago
Daniel Grunwald	ddff831cf0	#1292 : Fix some more problems with pinned locals. Let's distinguish between the original pinned locals and the PinnedRegion locals. The format need declarations if any are left over after transformations; the latter don't.	6 years ago
Daniel Grunwald	1f2d1660c8	#2023 : If blocks are reachable both from within the pinned region and from outside it, clone those blocks. This removes an error condition where pinned variables could remain after DetectPinnedRegions, resulting in invalid C#. The downside is that it's possible for the code size to increase exponentially when given sufficiently evil IL code.	6 years ago
Siegfried Pammer	8925b4ff7b	Inline variable declarations/modernize parts of our code base.	7 years ago
Daniel Grunwald	65fe59e393	#1918 : Fix a bunch of issues with pinned region detection. Not every pinned region has a clean `P = null` assignment to mark its end. If a second pinned region starts with the same variable `P`, consider that to mark the end of the previous pinned region for that variable. Also, fix a bunch of special cases with empty pinned regions.	7 years ago

Siegfried Pammer	c1fca21e8a	Make ILRange field private - introduce public API for IL range manipulation.	8 years ago
Daniel Grunwald	f6aae1f97d	Fix #1386 : MoveArrayToPointerToPinnedRegionInit: Only consider the pinned variable uses within the PinnedRegion This also makes CleanUpTryFinallyAroundPinnedRegion() redundant as it is no longer necessary to trigger the array-to-pointer transform; so the normal elimination of pinned variable resets is sufficient.	8 years ago
Daniel Grunwald	1ab11ba7ce	DetectPinnedRegions: also add debug step for failed CreatePinnedRegion() calls	8 years ago
