Bug ID: 110596
Summary: Documentation: typo in the docs for -Wnrvo
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: gennaro.prota+gccbugzilla at gmail dot com
Target Milestone: ---
>From the manual (currently,
<https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html>, but I'm afraid this
is a moving target):
-Wnrvo [...]
For instance, in the example below the compiler cannot elide copies from
both
v1 and b2, so it elides neither.
std::vector<int> f()
{
std::vector<int> v1, v2;
// ...
if (cond) return v1;
else return v2; // warning: not eliding copy
}
Clearly, the text should say "v1 and v2", not "v1 and b2".
