[cfe-dev] potential OpenMP back ports for 3.9.1

[Jack Howarth via cfe-dev]

Alexey,
      I scanned through the OpenMP commits in cfe trunk for potential
back ports to 3.9 branch for the 3.9.1 release. Do any of these merit
inclusion?
              Jack

Log:
[OpenMP] Add support for mapping array sections through pointer references.

Summary:
This patch fixes a bug in the map of array sections whose base is a
reference to a pointer. The existing mapping support was not prepared
to deal with it, causing the compiler to crash.

Mapping a reference to a pointer enjoys the same characteristics of a
regular pointer, i.e., it is passed by value. Therefore, the reference
has to be materialized in the target region.

Log:
[OpenMP] Add support to map member expressions with references to pointers.

Summary: This patch add support to map pointers through references in
class members. Although a reference does not have storage that a user
can access, it still has to be mapped in order to get the deep copy
right and the dereferencing code work properly.
