Subject: [PATCH] gdb/build: Fix Wpessimizing-move in clang build
Date: Fri, 28 Jan 2022 21:41:16 +0800 [thread overview]
Message-ID: <MEAP282MB029383DD920EBB5CBF2F8B79DD229@MEAP282MB0293.AUSP282.PROD.OUTLOOK.COM> (raw)
When building with clang, I run into an error:
...
tui/tui-disasm.c:138:25: error: moving a temporary object prevents copy
elision [-Werror,-Wpessimizing-move]
tal.addr_string = std::move (gdb_dis_out.release ());
^
tui/tui-disasm.c:138:25: note: remove std::move call here
tal.addr_string = std::move (gdb_dis_out.release ());
^~~~~~~~~~~ ~
...
The error above is caused by the recent commit 5d10a2041eb8 ("gdb: add
string_file::release method").
Fix this by removing std::move.
Build on x86_64-linux with clang 13.0.0.
