<pre>Hi, all.
This small case, bug.cc, clang can not emit the line or column number on
diagnostic message.
$cat bug.cc
volatile enum a { };
$clang++ -c bug.cc
warning: 'volatile' is not permitted on a declaration of a type
[-Wmissing-declarations]
1 warning generated.
$clang++ -c -pedantic-errors bug.cc
error: 'volatile' is not permitted on a declaration of a type
[-Werror,-Wmissing-declarations]
1 error generated.
While in GCC
$g++ -c bug.cc
bug.cc:1:1: error: ‘volatile’ can only be specified for objects and functions
1 | volatile enum a { };
| ^~~~~~~~
$clang++ -v
clang version 11.0.0 (<a href="https://github.com/llvm/llvm-project">https://github.com/llvm/llvm-project</a>
