Bug ID: 106272
Summary: clang build: new warning ?
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: dcb314 at hotmail dot com
Target Milestone: ---
Recent gcc builds with clang say this:
libcpp/include/line-map.h:1882:12: warning: moving a temporary object prevents
copy elision [-Wpessimizing-move]
I have little idea what that means, but the line of code is
return std::move (label_text (buffer, true));
This new warning appears about 700 times, so it might be important.
