[PATCH 0/4] OpenMP: Parsing of lvalues for "map" clauses for C andjC++

[Julian Brown]

This patch series builds on top of the previously-posted series:

"Topological sort for OpenMP 5.0 base pointers"
https://gcc.gnu.org/pipermail/gcc-patches/2021-August/577211.html

and:

"OpenMP: Deep struct dereferences"
https://gcc.gnu.org/pipermail/gcc-patches/2021-October/580721.html

To add support for parsing general lvalues in "map" clauses in both
C and C++.  A new "address inspector" class is introduced in order to
unify address analyses from several places in the C/C++ front-ends which
had some level of duplication.

Tested with offloading to NVPTX, and bootstrapped.  OK?

Julian Brown (4):
  Add debug_omp_expr
  OpenMP: Add inspector class to unify mapped address analysis
  OpenMP: lvalue parsing for map clauses (C++)
  OpenMP: lvalue parsing for map clauses (C)
