decl_to_instance_map

decl_to_instance_map_t* decl_to_instance_map

extern

Map DECLs to instance discriminators.  This is allocated and
defined in ada/gcc-interfaces/trans.cc, when compiling with -gnateS.
Mappings from this table are saved and restored for LTO, so
link-time compilation will have this map set, at least in
partitions containing at least one DECL with an associated instance
discriminator.
