When I run process-dies-while-detaching.exp with GDBserver, I see many warnings printed by GDBserver, ptrace(regsets_fetch_inferior_registers) PID=26183: No such process ptrace(regsets_fetch_inferior_registers) PID=26183: No such process ptrace(regsets_fetch_inferior_registers) PID=26184: No such process ptrace(regsets_fetch_inferior_registers) PID=26184: No such process regsets_fetch_inferior_registers is called when GDBserver resumes each lwp. #2 0x0000000000428260 in regsets_fetch_inferior_registers (regsets_info=0x4690d0 <aarch64_regsets_info>, regcache=0x31832020) at /home/yao/SourceCode/gnu/gdb/git/gdb/gdbserver/linux-low.c:5412 #3 0x00000000004070e8 in get_thread_regcache (thread=0x31832940, fetch=fetch@entry=1) at /home/yao/SourceCode/gnu/gdb/git/gdb/gdbserver/regcache.c:58 #4 0x0000000000429c40 in linux_resume_one_lwp_throw (info=<optimized out>, signal=0, step=0, lwp=0x31832830) at /home/yao/SourceCode/gnu/gdb/git/gdb/gdbserver/linux-low.c:4463 #5 linux_resume_one_lwp (lwp=0x31832830, step=<optimized out>, signal=<optimized out>, info=<optimized out>) at /home/yao/SourceCode/gnu/gdb/git/gdb/gdbserver/linux-low.c:4573 The is the case that threads are disappeared when GDB/GDBserver resumes them. We check errno for ESRCH, and don't print error messages, like what we are doing in regsets_store_inferior_registers. gdb/gdbserver: 2016-08-04 Yao Qi <yao.qi@linaro.org> * linux-low.c (regsets_fetch_inferior_registers): Check errno is ESRCH or not. |

README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
