Those routines in GRHydro instantiate many C++ templates for the different cases. Overall compilation speed probably improves if one makes one tiny C++ file per instantiation. The instantiation happens in these lines:
INSTANTIATE_RECONSTRUCTION_OPERATOR(GRHydro_WENOReconstruct1d_cxx00) INSTANTIATE_RECONSTRUCTION_OPERATOR(GRHydro_WENOReconstruct1d_cxx01) INSTANTIATE_RECONSTRUCTION_OPERATOR(GRHydro_WENOReconstruct1d_cxx10) INSTANTIATE_RECONSTRUCTION_OPERATOR(GRHydro_WENOReconstruct1d_cxx11) *each* of which (in the macro INSTANTIATE_RECONSTRUCTION_OPERATOR) instantiates 12 copies of the given routine. The macro is defined in GRHydro_Reconstruct_drv_cxx.hh . Yours, Roland -- My email is as private as my paper mail. I therefore support encrypting and signing email messages.
