Bug ID: 99318
Summary: [10/11 Regression] -Wdeprecated-declarations where
non-should be?
Product: gcc
Version: 10.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: gcc-bugs at marehr dot dialup.fu-berlin.de
Target Milestone: ---
Hello gcc-team,
since gcc 10 the following code throws a deprecation warning, even though it
doesn't use any deprecated code.
```c++
template <typename derived_type>
class alphabet_base
{
[[deprecated("message")]] unsigned char_to_rank_table(char const chr)
{
using index_t = unsigned;
return derived_type::char_to_rank[static_cast<index_t>(chr)];
}
};
```
gives the following warning:
```
<source>: In member function 'unsigned int
alphabet_base<derived_type>::char_to_rank_table(char)':
<source>:7:55: warning: 'unsigned int
alphabet_base<derived_type>::char_to_rank_table(char)' is deprecated: message
[-Wdeprecated-declarations]
7 | return derived_type::char_to_rank[static_cast<index_t>(chr)];
| ^~~~~~~
<source>:4:40: note: declared here
4 | [[deprecated("message")]] unsigned char_to_rank_table(char const
chr)
| ^~~~~~~~~~~~~~~~~~
Compiler returned: 0
```
