Bug ID: 111895
Summary: error: invalid operands of types 'unsigned char:2' and
'int' to binary 'operator!='
Product: gcc
Version: 13.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: nabijaczleweli at nabijaczleweli dot xyz
Target Milestone: ---
Simplified from other code:
#include <cstdint>
enum class o_field : std::uint8_t { no, yes, different_from_s };
struct fields {
o_field o : 2;
};
bool func(fields f) { return static_cast<bool>(f.o); }
yields
main.cpp: In function 'bool func(fields)':
main.cpp:8:50: error: invalid operands of types 'unsigned char:2' and 'int'
to binary 'operator!='
8 | bool func(fields f) { return static_cast<bool>(f.o); }
| ~~^
Which is nonsensical. Clang accepts this, and does the expected thing.
