This patch catches invalid initialization of non-POD types with memset, at compile time. This is what I used to catch the problems fixed by the previous patches in the series: $ make -k 2>&1 | grep "deleted function" src/gdb/breakpoint.c:951:53: error: use of deleted function ‘void* memset(T*, int, size_t) [with T = bp_location; <template-parameter-1-2> = void; size_t = long unsigned int]’ src/gdb/breakpoint.c:7325:32: error: use of deleted function ‘void* memset(T*, int, size_t) [with T = bp_location; <template-parameter-1-2> = void; size_t = long unsigned int]’ src/gdb/btrace.c:1153:42: error: use of deleted function ‘void* memset(T*, int, size_t) [with T = btrace_insn; <template-parameter-1-2> = void; size_t = long unsigned int]’ ... gdb/ChangeLog: 2017-04-25 Pedro Alves <palves@redhat.com> * common/common-defs.h: Include "common/poison.h". * common/function-view.h: (Not, Or, Requires): Move to traits.h and adjust. * common/poison.h: New file. * common/traits.h: Include <type_traits>. (Not, Or, Requires): New, moved from common/function-view.h.
