This reverts the part of the commit 1906dc30a5
which introduced modifications in the expr templates of the Green's
functions. The commit had introduced some bugs and this revert
removes them (the expr templates will be taken care of fully in later
commits). This is a temporary fix for issues #18 and #25.
reverted: triqs/gfs/data_proxies.hpp
reverted: triqs/gfs/gf.hpp
reverted: triqs/gfs/gf_expr.hpp
- add move semantics in expression template.
for gfs :
- rm descriptor
- Remove data from expr, rewrote assignment
which now iterates on the mesh, simply.
RHS models now FunctionOnMesh
- This fix the multiplication bug of gf
- Remove assign_no_resize/assign_with_resize from proxy
- change : all objects are by default
stored now by reference, not by copy any more.
Unless the trait force_copy_in_expr is true.
- rvalue refs are moved into the tree
- simplifies a lot the writing of lazy method, objects.
- added a macro for methods
- tests ok. Further check needed to control absence of copies...
- improved documentation
gcc has a pb because the template mesh<Variable,Opt>
has the name same as the gf mesh method (!).
Clang is fine however on this...
Solution : rename the template mesh<...> to gf_mesh...
Not very elegant, but ok.
