Bug ID: 107942
Summary: [10/11/12/13 Regression] Documentation of the volatile
style for noreturn is gone
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Keywords: documentation
Severity: normal
Priority: P3
Component: c
Assignee: unassigned at gcc dot gnu.org
Reporter: pinskia at gcc dot gnu.org
Target Milestone: ---
r5-7698-g8648c55f3b703a removed the documentation of the volatile style of
noreturn even though it is still implemented as of today.
Take:
```
typedef void voidfn ();
volatile voidfn fatal;
void fatal() {}
```
This still warns today with the C front-end:
<source>: In function 'fatal':
<source>:8:1: warning: 'noreturn' function does return
8 | }
| ^
The reasoning why the documentation was removed was it references an (real) old
version of GCC.=
