From 8118159c69a957292ce701b3d2937f19a0d0f973 Mon Sep 17 00:00:00 2001 From: Tom de Vries Date: Fri, 12 Jun 2020 18:36:56 +0200 Subject: [PATCH] [gdbserver] Fix Wlto-type-mismatch for debug_agent When building gdb including gdbserver with CFLAGS/CXXFLAGS -O2 -g -flto=auto, I run into: ... src/gdbserver/../gdbsupport/agent.h:47:13: error: type of 'debug_agent' \ does not match original declaration [-Werror=lto-type-mismatch] extern bool debug_agent; ^ src/gdbserver/ax.cc:28:5: note: type 'int' should match type 'bool' int debug_agent = 0; ^ src/gdbserver/ax.cc:28:5: note: 'debug_agent' was previously declared here src/gdbserver/ax.cc:28:5: note: code may be misoptimized unless \ -fno-strict-aliasing is used ... Fix this by changing the type of debug_agent in ax.cc from int to bool. Tested on x86_64-linux. --- gdbserver/ax.cc | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/gdbserver/ax.cc b/gdbserver/ax.cc index 213db410a07..42d28128fa6 100644 --- a/gdbserver/ax.cc +++ b/gdbserver/ax.cc @@ -25,7 +25,7 @@ static void ax_vdebug (const char *, ...)
