Member Typedef Documentation
| typedef std::pair<llvm::Value*, llvm::Value*> comma::BoundsEmitter::LUPair |
Several methods return a std::pair of values representing a range. The following typedef provides a shorthand. The first component of such a pair contains the lower bound and the second component contains the upper bound.

Member Function Documentation
| llvm::Value * BoundsEmitter::computeBoundLength | ( | llvm::IRBuilder<> & | Builder, | |
| llvm::Value * | bounds, | |||
| unsigned | index | |||
| ) |
Emits code which computes the length of the given bounds value.
The returned Value is always an i32. This may change in the future when LLVM supports i64 alloca's.
Definition at line 190 of file BoundsEmitter.cpp.
| llvm::Value * BoundsEmitter::computeIsNull | ( | llvm::IRBuilder<> & | Builder, | |
| llvm::Value * | bounds, | |||
| unsigned | index | |||
| ) |
Emits code which tests if the given bounds object has a null range at the given index. The reuturn value is always an i1.
Definition at line 247 of file BoundsEmitter.cpp.
| llvm::Value * BoundsEmitter::computeTotalBoundLength | ( | llvm::IRBuilder<> & | Builder, | |
| llvm::Value * | bounds | |||
| ) |
Emits code which computes the total length of the given bounds value.
Like computeBoundLength(), this method returns an i32.

| static LUPair comma::BoundsEmitter::getBounds | ( | llvm::IRBuilder<> & | Builder, | |
| llvm::Value * | bounds, | |||
| unsigned | index | |||
| ) | [inline, static] |
Convenience method to pack the results of getLowerBound() and getUpperBound() into a std::pair.
Definition at line 86 of file BoundsEmitter.h.
| llvm::Value * BoundsEmitter::getLowerBound | ( | llvm::IRBuilder<> & | Builder, | |
| const Range * | range | |||
| ) |
Evaluates the given range and returns the lower bound.
Definition at line 129 of file BoundsEmitter.cpp.
| llvm::Value * BoundsEmitter::getLowerBound | ( | llvm::IRBuilder<> & | Builder, | |
| const DiscreteType * | type | |||
| ) |
Evaluates the range of the given scalar type and returns the lower bound.
Definition at line 103 of file BoundsEmitter.cpp.
| static llvm::Value* comma::BoundsEmitter::getLowerBound | ( | llvm::IRBuilder<> & | Builder, | |
| llvm::Value * | bounds, | |||
| unsigned | index | |||
| ) | [inline, static] |
Returns the lower bound at the given index.
Definition at line 57 of file BoundsEmitter.h.
| BoundsEmitter::LUPair BoundsEmitter::getRange | ( | llvm::IRBuilder<> & | Builder, | |
| const Range * | range | |||
| ) |
Evaluates a range and returns the lower and upper bounds as a pair.
Definition at line 182 of file BoundsEmitter.cpp.
| BoundsEmitter::LUPair BoundsEmitter::getScalarBounds | ( | llvm::IRBuilder<> & | Builder, | |
| const DiscreteType * | type | |||
| ) |
Evaluates the range of the given scalar type and returns the lower and upper bounds as a pair.
If the current frame has a bounds entry for the given type this method will use them. Otherwise, if the type has dynamic constraints, the computed bounds are registered with the frame and associated with the type.
Definition at line 66 of file BoundsEmitter.cpp.
| const llvm::StructType * BoundsEmitter::getType | ( | const ArrayType * | arrTy | ) |
Returns the LLVM type which represents the bounds of the given Comma array type.
- Note:
- This is simply a convinience wrapper around CodeGenTypes::lowerArrayBounds().
Definition at line 50 of file BoundsEmitter.cpp.
| llvm::Value * BoundsEmitter::getUpperBound | ( | llvm::IRBuilder<> & | Builder, | |
| const Range * | range | |||
| ) |
Evaluates the given range and returns the upper bound.
Definition at line 144 of file BoundsEmitter.cpp.
| llvm::Value * BoundsEmitter::getUpperBound | ( | llvm::IRBuilder<> & | Builder, | |
| const DiscreteType * | type | |||
| ) |
Evaluates the range of the given scalar type and returns the upper bound.

| static llvm::Value* comma::BoundsEmitter::getUpperBound | ( | llvm::IRBuilder<> & | Builder, | |
| llvm::Value * | bounds, | |||
| unsigned | index | |||
| ) | [inline, static] |
Returns the upper bound at the given index.

| llvm::Value * BoundsEmitter::synthAggregateBounds | ( | llvm::IRBuilder<> & | Builder, | |
| AggregateExpr * | agg, | |||
| llvm::Value * | dst = 0 | |||
| ) |
Constructs an LLVM structure object representing the bounds of the given positional aggregate expression.
If dst is non-null the synthesized bounds are stored into the given location.

| llvm::Value * BoundsEmitter::synthArrayBounds | ( | llvm::IRBuilder<> & | Builder, | |
| ArrayType * | arrTy | |||
| ) |
Computes the bounds of the given array type.

| llvm::Value * BoundsEmitter::synthRange | ( | llvm::IRBuilder<> & | Builder, | |
| llvm::Value * | lower, | |||
| llvm::Value * | upper | |||
| ) |
Packs the given values into a bounds structure.
Both values must be of the same integer type.
Definition at line 168 of file BoundsEmitter.cpp.
| llvm::Value * BoundsEmitter::synthRange | ( | llvm::IRBuilder<> & | Builder, | |
| const Range * | range | |||
| ) |
Evaluates a range and returns a corresponding bounds structure.

| llvm::Value * BoundsEmitter::synthScalarBounds | ( | llvm::IRBuilder<> & | Builder, | |
| const DiscreteType * | type | |||
| ) |
Evaluates the range of the given scalar type and returns a corresponding bounds structure.
If the current frame has a bounds entry for the given type this method will use them. Otherwise, if the type has dynamic constraints, the computed bounds are registered with the frame and associated with the type.
