dd322be238 C++: Remove noise from argHasPostUpdate check 
This consistency check seems to have value for AST data flow, but I've
disabled it on the IR for now.

This commit also includes two unrelated changes that seem to fix a
semantic merge conflict.

c3a6ca0d9a C++: Better support for complex numbers in IR and AST 
This PR adds better support for differentiating complex and imaginary floating-point types from real floating-point types, in both the AST and in the IR type system.

*AST Changes*
- Introduces the new class `TypeDomain`, which can be either `RealDomain`, `ImaginaryDomain` or `ComplexDomain`. "type domain" is the term used for this concept in the C standard, and I couldn't think of a better one.
- Introduces `FloatingPointType.getDomain()`, to get the type domain of the type.
- Introduces `FloatingPointType.getBase()`, to get the numeric base of the type (either 2 or 10).
- Introduces three new subtypes of `FloatingPointType`: `RealNumberType`, `ComplexNumberType`, and `ImaginaryNumberType`, which differentiate between the types based on their type domain. Note that the decimal types (e.g., `_Decimal32`) are included in `RealNumberType`.
- Introduces two new subtypes of `FloatingPointType`: `BinaryFloatingPointType` and `DecimalFloatingPointType`, which differentiate between the types based on their numeric base, independent of type domain.

*IR Changes*
- `IRFloatingPointType` now has two additional parameters: the base and the type domain.
- New test that ensures that C++ types get mapped to the correct IR types.
- New IR test that verifies the IR for some basic usage of complex FP types.

fbef146a49 C++: Remove PositionalArgumentWithoutWriteSideEffectNode (since not all arguments need a PostUpdateNode). Also generalized the added flow rule in simpleLocalFlowStep since there isn't always a ChiInstruction - for instance of it's a write to a struct that only has a single field. 2020-03-26 11:39:20 +01:00
