2020-08-23ada-lex.l: Ignore register diagnostic also for g++ defaulting to ISO C++17Mark Wielaard1-0/+5
Building with a really old flex and a really new g++ is probably not recommended, but it should not cause compile errors. gdb/ChangeLog: * ada-lex.l: Extend register warnings diagnostics comment for g++. include/ChangeLog: * diagnostics.h (DIAGNOSTIC_IGNORE_DEPRECATED_REGISTER): Also define for GCC version 7.0 or higher.

2019-12-12Fix unused function errorLuis Machado1-9/+0
Attempting to build GDB in Ubuntu 16.04.6 LTS on x86_64, I ran into warnings that caused the build to fail: binutils-gdb/gdb/gdbsupport/safe-strerror.c:44:1: error: ‘char* select_strerror_r(char*, char*)’ defined but not used [-Werror=unused-function] select_strerror_r (char *res, char *) The diagnostic macro DIAGNOSTIC_IGNORE_UNUSED_FUNCTION seems to expand correctly to its respective pragma, but this doesn't seem to have an effect on the warning. I tried to use the pragma explicitly and got the same result. ATTRIBUTE_UNUSED works fine in this case if you put it in both functions, which should fix warnings for both gdb and gdbserver builds. The compiler version is gcc (Ubuntu 5.4.0-6ubuntu1~16.04.11) 5.4.0 20160609. This is likely the result of PR64079 in GCC, which was fixed by commit 9e96f1e1b9731c4e1ef4fbbbf0997319973f0537. To prevent other developers from attempting to use this macro, only to get confused by it not working as expected, it seems better to not define this particular macro. gdb/ChangeLog: 2019-12-12 Luis Machado <luis.machado@linaro.org> * gdbsupport/safe-strerror.c: Don't include diagnostics.h. (select_strerror_r): Use ATTRIBUTE_UNUSED instead of the diagnostics macros. include/ChangeLog: 2019-12-12 Luis Machado <luis.machado@linaro.org> * diagnostics.h (DIAGNOSTIC_IGNORE_UNUSED_FUNCTION). Remove definitions. Change-Id: Iad6123d61d76d111e3ef8d24aa8c60112304c749

2018-09-05Disable -Wformat-nonliteral in parts of printcmd.cSimon Marchi1-0/+12
commit 3322c5d9a1 ("Remove unneeded explicit .o targets") broke the build with clang, because -Wno-format-nonliteral was in fact needed. This patch fixes the problem by introducing DIAGNOSTIC_IGNORE_FORMAT_NONLITERAL and using it in printcmd.c. This seems preferable to reverting the patch because now the warning suppression is more targeted. gdb/ChangeLog 2018-09-05 Simon Marchi <simon.marchi@ericsson.com> * printcmd.c (printf_c_string): Use DIAGNOSTIC_IGNORE_FORMAT_NONLITERAL. (printf_wide_c_string, printf_pointer, ui_printf): Likewise. include/ChangeLog 2018-09-05 Simon Marchi <simon.marchi@ericsson.com> * diagnostics.h (DIAGNOSTIC_IGNORE_FORMAT_NONLITERAL): New macro.

2018-07-05darwin: Silence syscall deprecated declaration warningSimon Marchi1-0/+6
This patch silences this warning: /Users/simark/src/binutils-gdb/gdb/darwin-nat.c:839:10: error: 'syscall' is deprecated: first deprecated in macOS 10.12 - syscall(2) is unsupported; please switch to a supported interface. For SYS_kdebug_trace use kdebug_signpost(). [-Werror,-Wdeprecated-declarations] res = syscall (SYS___pthread_kill, thread->gdb_port, nsignal); ^ /usr/include/unistd.h:745:6: note: 'syscall' has been explicitly marked deprecated here int syscall(int, ...); ^ The comment of the new pthread_kill function explains why we use the syscall function directly. include/ChangeLog: * diagnostics.h (DIAGNOSTIC_IGNORE_DEPRECATED_DECLARATIONS): Define for clang. gdb/ChangeLog: * darwin-nat.c (darwin_pthread_kill): New function. (darwin_resume_thread): Use darwin_pthread_kill.
