Hi, I see this error when GDB connects with qemu, (gdb) n .... Sending packet: $vCont;c#a8...Ack Packet received: Ffstat,00000001,f6fff038 Cannot execute this command while the target is running. Use the "interrupt" command to stop the target and then try again. looks we don't set rs->waiting_for_stop_reply to zero before handle fileio request, #10 0x00000000005edb64 in target_write (len=64, offset=4143968312, buf=0x7fffffffd570 "\375\377\377\377", annex=0x0, object=TARGET_OBJECT_MEMORY, ops=<optimised out>) at /home/yao/SourceCode/gnu/gdb/git/gdb/target.c:1922 #11 target_write_memory (memaddr=memaddr@entry=4143968312, myaddr=myaddr@entry=0x7fffffffd6a0 "", len=len@entry=64) at /home/yao/SourceCode/gnu/gdb/git/gdb/target.c:1500 #12 0x00000000004b2b41 in remote_fileio_func_fstat (buf=0x127b258 "") at /home/yao/SourceCode/gnu/gdb/git/gdb/remote-fileio.c:1037 #13 0x00000000004b1878 in do_remote_fileio_request (uiout=<optimised out>, buf_arg=buf_arg@entry=0x127b240) at /home/yao/SourceCode/gnu/gdb/git/gdb/remote-fileio.c:1204 #14 0x00000000005b8c7c in catch_exceptions_with_msg (func_uiout=<optimised out>, func=func@entry=0x4b1800 <do_remote_fileio_request>, func_args=func_args@entry=0x127b240, gdberrmsg=gdberrmsg@entry=0x0, mask=mask@entry=RETURN_MASK_ALL) at /home/yao/SourceCode/gnu/gdb/git/gdb/exceptions.c:187 #15 0x00000000005b8dea in catch_exceptions (uiout=<optimised out>, func=func@entry=0x4b1800 <do_remote_fileio_request>, func_args=func_args@entry=0x127b240, mask=mask@entry=RETURN_MASK_ALL) at /home/yao/SourceCode/gnu/gdb/git/gdb/exceptions.c:167 #16 0x00000000004b2fff in remote_fileio_request (buf=0x127b240 "Xf6fff038,0:", ctrlc_pending_p=0) at /home/yao/SourceCode/gnu/gdb/git/gdb/remote-fileio.c:1255 #17 0x0000000000496f12 in remote_wait_as (ptid=..., status=0x7fffffffdb20, options=1) at /home/yao/SourceCode/gnu/gdb/git/gdb/remote.c:6997 however, we did set rs->waiting_for_stop_reply to zero before Luis's patch https://sourceware.org/ml/gdb-patches/2015-10/msg00336.html In fact, Luis's patch v1 https://sourceware.org/ml/gdb-patches/2015-08/msg00809.html is about setting rs->waiting_for_stop_reply back to one after remote_fileio_request, which is correct. However during the review, the patch is changed and ends up with "not setting rs->waiting_for_stop_reply to zero". I manually test GDB, but I don't have a way to run regression tests. gdb: 2016-02-04 Yao Qi <yao.qi@linaro.org> * remote.c (remote_wait_as): Set rs->waiting_for_stop_reply to 0 before handling 'F' and set it back afterwards. |

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.
