Patch 10 was adjusted to use it. The patches without explicit approvals are still: - [06/10] gdb/solib-rocm: move per-inferior data to rocm_solib_ops - [08/10] gdb: add objfile -> solib backlink Below is the original cover letter, which still applies. This series adds support for having multiple solib_ops instances providing solibs for a given program_space. The main use case to justify this change is to make rocm_solib_ops less clunky. When debugging ROCm programs, we need to have an instance of svr4_solib_ops providing solibs for host shared libraries, and an instance of rocm_solib_ops providing solibs for device code objects. Since there can only be one solib_ops in a program, rocm_solib_ops has to wrap and replce the svr4_solib_ops instance previously installed. By allowing multiple solib_ops in the same program_space, the two solib_ops instances can co-exist without knowing each other. The main change is contained in the last patch. The patches before that are cleanup or preparatory patches.
