This fixes PR cli/15603. The bug here is that when a software watchpoint is being used, gdb will stop responding to C-c. This is a regression caused by the "catch signal" patch. The problem is that software watchpoints always end up on the bpstat list. However, this makes bpstat_explains_signal return BPSTAT_SIGNAL_HIDE, causing infrun to think that the signal is not a "random signal". The fix is to change bpstat_explains_signal to handle this better. I chose to do it in a "clean API" way, by passing the signal value to bpstat_explains_signal and then adding an explains_signal method for watchpoints, which handles the specifics. Built and regtested on x86-64 Fedora 18. New test case included. * break-catch-sig.c (signal_catchpoint_explains_signal): Add 'sig' argument. * breakpoint.c (bpstat_explains_signal): Add 'sig' argument. Special case signals other than GDB_SIGNAL_TRAP. (explains_signal_watchpoint): New function. (base_breakpoint_explains_signal): Add 'sig' argument. (initialize_breakpoint_ops): Set 'explains_signal' method for watchpoints. * breakpoint.h (struct breakpoint_ops) <explains_signal>: Add signal argument. (bpstat_explains_signal): Likewise. * infrun.c (handle_syscall_event, handle_inferior_event): Update. * gdb.base/random-signal.c: New file. * gdb.base/random-signal.exp: New file. |

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.
