Daniel Grunwald	fc73851bb4	#1610 : Slightly more aggressive copy propagation. This helps clean up the mess left behind when stack slots are not eliminated by the normal transforms. We previously didn't do this because aggressive copy propagation could confuse the normal transforms; but this is no longer an issue with the new pass ordering.	6 years ago
Siegfried Pammer	ec18094c65	Implement transformation of delegate construction with ldvirtftn.	6 years ago
Siegfried Pammer	65f9fe1076	Remove unused code.	6 years ago

Siegfried Pammer	1e3e8fdac1	Allow ref-locals to be initialized from nested field addresses.	6 years ago
Daniel Grunwald	df13f0ce01	Fix #1605 : Inline ref locals more aggressively; this is necessary for VB compound assignments.	6 years ago
Daniel Grunwald	0e0179edff	Improve NullPropagation (?.) when fields of value-type are involved.	6 years ago
Daniel Grunwald	7f8689c464	Allow inlining of compiler-generated value-type-temporaries when field accesses are involved.	6 years ago

Daniel Grunwald	97d490a3df	Slightly generalize the post-increment transform so that it no longer depends on copy propagation.	6 years ago
Siegfried Pammer	25f625af99	Move copy propagation after expression and statement transforms.	6 years ago
Siegfried Pammer	7d62a7e032	Reset HasInitialValue flag after TransformDisplayClassUsage.	6 years ago
Siegfried Pammer	e5f95143cf	TransformDisplayClassUsage: set HasInitialValue = true for newly introduced locals.	6 years ago
Daniel Grunwald	6c0216bbb9	Fix assertion in ReduceNestingTransform: after copying the exitInst, it was possible that the old copy of the exitInst became unreachable.	6 years ago
Daniel Grunwald	8117dfff4a	Fix #1242 : Discard unreachable code. Unreachable code is not part of the dominator tree, which most of our transforms are based on. In particular, dominance-based loop detection runs into the problem where unreachable code might have jumps into two independent loops. In that case, it's impossible to place the unreachable code in a way that avoids assertions / generating invalid C#. We establish the invariant that all blocks in a BlockContainer must be statically reachable from the entry point (-> every block is part of the dominator tree). This means transforms no longer have to deal with special cases for unreachable code. The "Remove dead and side effect free code" option still has an effect on dead stores, but unreachable code is now always removed (previously this also was dependent on this option).	6 years ago
Daniel Grunwald	c3037afa70	Fix #1352 : Assertion in NullableLiftingTransform.DoLift	6 years ago
Daniel Grunwald	539e3a906d	Fix #1552 : user-defined and decimal increments For user-defined increments, there were problems with Roslyn was optimizing out one of the stores. The new transform FixRemainingIncrements now takes increments/decrements that were not detected by TransformAssignment and introduces a temporary variable that can be incremented. This sometimes requires un-inlining via the new ILInstruction.Extract() operation. Extract() is not supported in all possible contexts, so it is possible but unlikely that some op_Increment calls remain. For decimals, the situation is different: legacy csc actually was optimizing "d + 1m" to "op_Increment(d)", so we can get rid of any left-over increments by undoing this optimization. This now happens in ReplaceMethodCallsWithOperators.	6 years ago
Siegfried Pammer	61231b7725	Fix #1593 : TransformCollectionAndObjectInitializers uses nested indexer call as target of object initializer.	6 years ago
Daniel Grunwald	856cedc95e	#1456 : add test case; add additional checks to ensure we only transform normal locals into using/foreach-locals	6 years ago
Daniel Grunwald	beed6b5e24	Remove MarkGeneratedVariables() step in AsyncAwaitDecompiler. This was left-over from earlier versions; but ILSpy stopped caring so much about variable vs. stack slot since Roslyn started to optimize more aggressively. The change of variable type caused problems for debug information and could even cause an assertion. Closes #1456, closes #1562.	6 years ago

Daniel Grunwald	ccdabf2325	Fix a bunch of XmlDoc compiler warnings.	6 years ago
Daniel Grunwald	b32cae412a	Eliminate BlockKind.PostfixOperator. We can now represent all compound assignments using the CompoundAssignInstruction, including those on local variables. Closes #1583.	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.	6 years ago
