Christoph Wille	fe9f6db3ee	Emit C# 7.1 default literals where the context supplies the type Shortening default(T) is the same problem as removing the redundant cast around a lambda whose delegate type the context already fixes, so it uses the same mechanism: ConvertTo makes the explicit type implicit when the conversion is an identity conversion and the caller allows an implicit one. The literal keeps the type it was shortened from, so any later conversion to a different type - or any context that requires an explicit type, such as an overload resolution recheck falling back to CastArguments - can spell default(T) out again. That keeps the value intact where the bare literal would change it, e.g. "object o = default(SomeStruct)", which boxes a non-null struct while "default" would be null. Because the shortened literal resolves to DefaultLiteralResolveResult, CallBuilder's existing overload resolution recheck sees a real default literal and rejects ambiguous calls on its own; no separate bookkeeping about which arguments may stay untyped is needed. Only the contexts that supply no target type at all restore the explicit form: an awaited expression, and arguments of operator methods, which later become operator or cast syntax rather than calls.

Siegfried Pammer	f8617a0c3d	Print 0m instead of default(decimal) for zero decimal values decimal has no IL literal: legacy csc compiles 0m to a Decimal.Zero field load, which already decompiled to the literal, but Roslyn compiles it to a zero-initialization, which decompiled to default(decimal). The two forms are bit-identical for decimal, so the literal is no less faithful to the IL and matches what a human writes; it also removes the per-compiler split in the CompoundAssignmentTest fixture.

Siegfried Pammer	87c13f99dc	Convert float/double += 1 into increment and decrement expressions Reviving the 2020 test-cases-fp-types fixtures (compound assignment on float, double and decimal) exposed an asymmetry: post-increment and post-decrement on float/double round-tripped as x++/x--, but the pre forms came back as x += 1f because the increment detection in PrettifyAssignments only accepted integer constants. C# defines ++/-- on floating-point types as adding or subtracting exactly 1, so the conversion is exact for a constant 1 operand. Decimal already works through the op_Increment/op_Decrement path.

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.	7 years ago
