https://sourceware.org/gdb/wiki/Common describes the following directory structure: gdb/nat/ Native target backend files. Code that interfaces with the host debug API. E.g., ptrace code, Windows debug API code, procfs code should go here. gdb/target/ Host-independent, target vector specific code (target_ops). gdb/common/ All other shared code. This commit moves all native target backend files currently in gdb/common to gdb/nat. gdb/ 2014-06-20 Gary Benson <gbenson@redhat.com> * common/gdb_thread_db.h: Moved to nat. All includes updated. * common/glibc_thread_db.h: Likewise. * common/i386-cpuid.h: Likewise. * common/i386-gcc-cpuid.h: Likewise. * common/linux-btrace.h: Likewise. * common/linux-osdata.h: Likewise. * common/linux-procfs.h: Likewise. * common/linux-ptrace.h: Likewise. * common/mips-linux-watch.h: Likewise. * common/linux-btrace.c: Moved to nat. * common/linux-osdata.c: Likewise. * common/linux-procfs.c: Likewise. * common/linux-ptrace.c: Likewise. * common/mips-linux-watch.c: Likewise. * nat/gdb_thread_db.h: Moved from common. * nat/glibc_thread_db.h: Likewise. * nat/i386-cpuid.h: Likewise. * nat/i386-gcc-cpuid.h: Likewise. * nat/linux-btrace.c: Likewise. * nat/linux-btrace.h: Likewise. * nat/linux-osdata.c: Likewise. * nat/linux-osdata.h: Likewise. * nat/linux-procfs.c: Likewise. * nat/linux-procfs.h: Likewise. * nat/linux-ptrace.c: Likewise. * nat/linux-ptrace.h: Likewise. * nat/mips-linux-watch.c: Likewise. * nat/mips-linux-watch.h: Likewise. * Makefile.in (HFILES_NO_SRCDIR): Reflect new locations. (object file files): Reordered. * gdb/copyright.py (EXCLUDE_LIST): Reflect new location of glibc_thread_db.h. gdb/gdbserver/ 2014-06-20 Gary Benson <gbenson@redhat.com> * Makefile.in (SFILES): Update locations for files moved from common to nat. (object file files): Reordered. gdb/testsuite/ 2014-06-20 Gary Benson <gbenson@redhat.com> * gdb.arch/i386-avx.exp: Fix include file location. * gdb.arch/i386-sse.exp: Likewise.
