Bug ID: 114970
Summary: 32-bit ARM gcc-14.1 new false positive -Wunused-value
Product: gcc
Version: 14.1.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++

Testcase
The attached reduced test case produces the following warning:
test.cpp:6:43: warning: value computed is not used [-Wunused-value]
6 | std::string_view prefix("<prefix>");
When compiling with:
-Wall -std=c++20 -O2
I see the warning when building for 32-bit ARM but not x86-64.
There is no warning with GCC 13.2.0.
