Sergio pointed out that the Windows builder was failing due to the -Wnarrowing patch, with: ../../binutils-gdb/gdb/windows-nat.c:301:27: error: narrowing conversion of '3221225477' from 'DWORD {aka long unsigned int}' to 'int' inside { } [-Wnarrowing] {-1, GDB_SIGNAL_UNKNOWN}}; ^ ../../binutils-gdb/gdb/windows-nat.c:301:27: error: narrowing conversion of '3221225725' from 'DWORD {aka long unsigned int}' to 'int' inside { } [-Wnarrowing] ../../binutils-gdb/gdb/windows-nat.c:301:27: error: narrowing conversion of '2147483651' from 'DWORD {aka long unsigned int}' to 'int' inside { } [-Wnarrowing] ../../binutils-gdb/gdb/windows-nat.c:301:27: error: narrowing conversion of '2147483652' from 'DWORD {aka long unsigned int}' to 'int' inside { } [-Wnarrowing] ../../binutils-gdb/gdb/windows-nat.c:301:27: error: narrowing conversion of '3221225614' from 'DWORD {aka long unsigned int}' to 'int' inside { } [-Wnarrowing] Looking into this, I found two things. First, in struct xlate_exception, it is better to have "them" be of type DWORD, as that's the type actually in use. Second, struct xlate_exception and xlate are not used in this file, because the code in windows_nat_target::resume is #if'd out. This patch changes the type of "them", but also similarly #if's out this object. In order to avoid a narrowing warning from the -1 entry, at Pedro's suggestion I have removed this and changed windows_nat_target::resume to use ranged for. Tested by rebuilding using the mingw toolchain on x86-64 Fedora 28. I also tested it by temporarily removing the "#if 0"s and rebuilding. gdb/ChangeLog 2018-08-29 Tom Tromey <tom@tromey.com> * windows-nat.c (struct xlate_exception) <them>: Change type to DWORD. (xlate): Fix formatting. Remove last entry. (struct xlate_exception, xlate): Comment out. (windows_nat_target::resume): Use ranged for. |

README
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.
