This patch implements the parsing and sema support for OpenMP from clause with potential user-defined mappers attached. User defined mapper is a new feature in OpenMP 5.0. A from clause can have an explicit or implicit associated mapper, which instructs the compiler to generate and use customized mapping functions. An example is shown below:

  struct S { int len; int *d; };
  #pragma omp declare mapper(id: struct S s) map(s, s.d[0:s.len])
  struct S ss;
  #pragma omp target update from(mapper(id): ss) // use the mapper with name 'id' to map ss from device
