Detailed Description

Abstraction of the iteration space for building the elemental compute loop of an array(-like) statement.

Constructor & Destructor Documentation

IterationSpace()

Fortran::lower::IterationSpace::IterationSpace ( const IterationSpace & from, llvm::ArrayRef< mlir::Value > prefix, llvm::ArrayRef< mlir::Value > suffix )

inlineexplicit

Create a copy of the from IterationSpace and prepend the prefix values and append the suffix values, respectively.

Member Function Documentation

getElement()

mlir::Value Fortran::lower::IterationSpace::getElement ( ) const

inline

Get the value that will be merged into the resultant array. This is the computed value that will be stored to the lhs of the assignment.

innerArgument()

mlir::Value Fortran::lower::IterationSpace::innerArgument ( ) const

inline

This is the output value as it appears as an argument in the innermost loop in the nest. The output value is threaded through the loop (and conditionals) to maintain proper SSA form.

iterVec()

llvm::SmallVector< mlir::Value > Fortran::lower::IterationSpace::iterVec ( ) const

inline

Returns a vector for the iteration space. This vector is used to access elements of arrays in the compute loop.

outerResult()

mlir::Value Fortran::lower::IterationSpace::outerResult ( ) const

inline

This is the output value as it appears as an output value from the outermost loop in the loop nest. The output value is threaded through the loop (and conditionals) to maintain proper SSA form.

setElement()

void Fortran::lower::IterationSpace::setElement ( fir::ExtendedValue && ele )

inline

Set the element value. This is the SSA value that corresponds to an element of the resultant array value.
