Bug ID: 90184
Summary: confusing diagnostic "attribute using prefix"
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: roland.illig at gmx dot de
Target Milestone: ---
From cp/parser.c:
pedwarn (input_location, 0,
"attribute using prefix only available "
"with %<-std=c++17%> or %<-std=gnu++17%>");
The words "attribute using prefix" can be interpreted by humans in really many
different ways:
- "attribute" can be a noun or an adjective
- "using" can be a verb or the C++ keyword
Is this about an "attribute that is using a prefix"?
Is this about a "prefix to an attribute called "using""?
Is this about a prefix called "attribute using"?
Since the comment above this diagnostic mentions that "attribute-using-prefix"
is a fixed term in the C++ grammar, the diagnostic should use hyphens instead
of spaces.
