Detailed Description

A dictionary entry of ssa-values that together compose a variable referenced by a Symbol. For example, the declaration

CHARACTER(LEN=i) :: c(j1,j2)

is a single variable c. This variable is a two-dimensional array of CHARACTER. It has a starting address and three dynamic properties: the LEN parameter i a runtime value describing the length of the CHARACTER, and the j1 and j2 runtime values, which describe the shape of the array.

The lowering bridge needs to be able to record all four of these ssa-values in the lookup table to be able to correctly lower Fortran to FIR.

VT

using Fortran::lower::SymbolBox::VT

Initial value:

 
      std::variant<Intrinsic, FullDim, Char, CharFullDim, PointerOrAllocatable,
                   Box, fir::FortranVariableOpInterface, None>

Member Function Documentation

getAddr()

mlir::Value Fortran::lower::SymbolBox::getAddr ( ) const

inline

Get address of the boxed value. For a scalar, this is the address of the scalar. For an array, this is the address of the first element in the array, etc.
