…rated IR does not pass the mlir-opt verifier. Tested on all the offload examples
…tion arguments are dereferenced, since HLS is not compatible with pointers to pointers. OpenMP variables in the omp.map.info operations are forwarded and the omp.target operation is forwarded (operands are forwarded to the block operations). Tested with offload/ex1.F90

… earlier in the pipeline. Also, remove attributes from the module, since they are incompatible with the downgrading to LLVM v7
…nly works when called after offload and extract-target, target-to-hls, but it is not enforced yet for debuggability

This pass transforms a target function generated with the
extract-targetpass to an HLS compatible format. This PR includes the changes to theextract-targetpass to, since this pass depends on it - check #9 for details.The arguments to the target function are dereferenced, since HLS does not accept pointers to pointers. The operands of the
omp.map.infooperations are forwarded and so are the operands of theomp.targetoperation, so that the operations inside its block can manipulate arrays. Theomp.target,omp.boundsandomp.map.infooperations are removed. Other operations, such asomp.parallelare not treated yet, but will be replaced by the corresponding HLS operation in thehlsdialect.Currently working for
offload/ex1.F90
