Each time a dll is loaded, update_solib_list is called. This in turn calls deep down xfer_partial -> windows_xfer_shared_libraries, which calls windows_xfer_shared_library for each loaded dll, and pe_text_section_offset reads the dll for the text section offset. Also if the data provided by xfer_partial is bigger than 4K, then all of this is done for each 4K chunk (see target_read_alloc_1). Caching of the text section offset improves the startup time of an application with >300 dynamically loaded plugins from 2m10s to 10s. And the shutdown time improves from 2m to 2s. gdb/ChangeLog: 2020-01-23 Hannes Domani <ssbssa@yahoo.de> * i386-cygwin-tdep.c (core_process_module_section): Update. * windows-nat.c (struct lm_info_windows): Add text_offset. (windows_xfer_shared_libraries): Update. * windows-tdep.c (windows_xfer_shared_library): Add text_offset_cached argument. * windows-tdep.h (windows_xfer_shared_library): Update.
