For WOW64 processes, the Wow64* variants of SuspendThread, GetThreadContext, SetThreadContext, and GetThreadSelectorEntry have to be used instead. And instead of EnumProcessModules, EnumProcessModulesEx with LIST_MODULES_32BIT is necessary. gdb/ChangeLog: 2020-03-04 Hannes Domani <ssbssa@yahoo.de> * NEWS: Mention support for WOW64 processes. * amd64-windows-nat.c (amd64_mappings): Rename and remove static. (amd64_windows_segment_register_p): Remove static. (_initialize_amd64_windows_nat): Update. * configure.nat <windows> (NATDEPFILES): Add i386-windows-nat.o. * i386-windows-nat.c (context_offset): Update. (i386_mappings): Rename and remove static. (i386_windows_segment_register_p): Remove static. (_initialize_i386_windows_nat): Update. * windows-nat.c (STATUS_WX86_BREAKPOINT): New macro. (STATUS_WX86_SINGLE_STEP): New macro. (EnumProcessModulesEx): New macro. (Wow64SuspendThread): New macro. (Wow64GetThreadContext): New macro. (Wow64SetThreadContext): New macro. (Wow64GetThreadSelectorEntry): New macro. (windows_set_context_register_offsets): Add static. (windows_set_segment_register_p): Likewise. (windows_add_thread): Adapt for WOW64 processes. (windows_fetch_one_register): Likewise. (windows_nat_target::fetch_registers): Likewise. (windows_store_one_register): Likewise. (display_selector): Likewise. (display_selectors): Likewise. (handle_exception): Likewise. (windows_continue): Likewise. (windows_nat_target::resume): Likewise. (windows_add_all_dlls): Likewise. (do_initial_windows_stuff): Likewise. (windows_nat_target::attach): Likewise. (windows_get_exec_module_filename): Likewise. (windows_nat_target::create_inferior): Likewise. (windows_xfer_siginfo): Likewise. (_initialize_loadable): Initialize Wow64SuspendThread, Wow64GetThreadContext, Wow64SetThreadContext, Wow64GetThreadSelectorEntry and EnumProcessModulesEx. * windows-nat.h (windows_set_context_register_offsets): Remove declaration. (windows_set_segment_register_p): Likewise. (i386_windows_segment_register_p): Add declaration. (amd64_windows_segment_register_p): Likewise.
