+ * linux-proc.c: New file. Implement child_pid_to_exec_file,
+ so that attaching to a pid will automatically read the process's
+ symbol file and shlibs.
+ * Makefile.in: Add rule for linux-proc.o.
+ * config/nm-linux.h: Define CHILD_PID_TO_EXEC_FILE.
+ * config/alpha/alpha-linux.mh: Add linux-proc.o to NATDEPFILES.
+ * config/arm/linux.mh: Ditto.
+ * config/i386/linux.mh: Ditto.
+ * config/i386/x86-64linux.mh: Ditto.
+ * config/ia64/linux.mh: Ditto.
+ * config/m68k/linux.mh: Ditto.
+ * config/mips/linux.mh: Ditto.
+ * config/powerpc/linux.mh: Ditto.
+ * config/sparc/linux.mh: Ditto.
