This commit reworks the helper methods for model::QualifiedType, to
properly traverse typedefs.
These methods are used to check if a QualifiedType is:
- scalar
- primitive
- float
- void
- pointer
- array
This commit add the methods for checking pointers and arrays (that
weren't available before), reworks all the helpers so that they all
traverse typedefs, and adds comments so that it's clear that they
traverse typedefs.
This commit adds the static methods:
- model::Qualifier::isConst
- model::Qualifier::isArray
- model::Qualifier::isPointer
These methods replace the old, non-static, methods:
- model::Qualifier::isConst
- model::Qualifier::isArray
- model::Qualifier::isPointer
Having these method static is very helpful for filtering, when
iterating on sequences of qualifiers, such as:
for (const auto &Q :
llvm::make_filter_range(Qualifiers, Qualifier::isPointer)) {
// do stuff with Q
}
This will be very helpful for defining other helper functions for
model::QualifiedType.
This commit also drops the non-static version of the methods, since they
are redundant, and because they would cause ambiguity and failure of
type inference in the snippet above, making them effectively useless for
the goal they were designed for, which is filtering ranges.
This is a big step to split revng-lift in two parts: one that only
writes the model and one that actually lifts to LLVM IR.
* Introduce `revng import binary`
* Split off `BinaryFile.h`
* Drop `revng.h`
* `GeneratedCodeBasicInfo`: use model
* Reduce role of `GeneratedCodeBasicInfo` in favor of
`model::Architecture` and `model::Register` methods
* `CodeGenerator`: adopt `RawBinaryView` and model
* `JumpTargetManager`: adopt `RawBinaryView` and model
* `ExternalJumpsHandler`: adopt model
* `InstructionTranslator`: discard `Architecture` in favor of
`EndianessMismatch`
* Many other changes
1. Hoist the logic to retrieve a model CallEdge from an llvm::CallInst
out of `getCallSitePrototype()`, in a separate `getCallEdge()`
function.
2. Modify `getCallSitePrototype()` so that the parent function's type is
optional.
Inject is meant to inject a model into an `llvm::Module`, but it fails
when operating on a Module that had no model metadata.
This commit fixes the bug.
This commit switches from `deduplicateNames`, which changed certain
`CustomName` values, to `promoteOriginalName`, which updates empty
`CustomName` using non-ambiguous versions of `OriginalName`.
The goal of `OriginalName` is to keep track of the original name of a
symbol upon import.
In future, this will also be used to promote it to `CustomName`.
Model classes are now described by a YAML document, which is used to
generate C++ headers containing classes and all the boilerplate
required for YAML serialization/deserialization, usage in
SortedVectors, etc. See the README in include/revng/Model for more
info.
