Bug ID: 89882
Summary: [8/9 Regression] Extra caret marker when issuing
diagnostics for the "'friend' used outside of class"
error
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Keywords: diagnostic
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: asolokha at gmx dot com
Target Milestone: ---
gcc 9 and 8 emit what I believe is a superfluous marker when issuing a
diagnostic for the following invalid code:
friend void
foo ();
% g++-9.0.0-alpha20190324 -fsyntax-only ehvo8syg.cc
ehvo8syg.cc:1:1: error: 'friend' used outside of class
1 | friend void
| ^~~~~~
| ------
Or is the second line of dashes meant to give a cue that the marked substring
have to be simply removed? If so, it is seemingly inconsistent, as there's no
such lines for other invalid specifiers in the following example:
friend virtual void
foo () override;
% g++-9.0.0-alpha20190324 -fsyntax-only ehvo8syg.cc
ehvo8syg.cc:1:1: error: 'friend' used outside of class
1 | friend virtual void
| ^~~~~~
| ------
ehvo8syg.cc:1:8: error: 'virtual' outside class declaration
1 | friend virtual void
| ^~~~~~~
ehvo8syg.cc:2:8: error: virt-specifiers in 'foo' not allowed outside a class
definition
2 | foo () override;
| ^~~~~~~~
