Bug ID: 90141
Summary: Missing test case for ambiguous -gdwarf command line
options
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: debug
Assignee: unassigned at gcc dot gnu.org
Reporter: roland.illig at gmx dot de
Target Milestone: ---
From opts.c:
case OPT_gdwarf:
if (arg && strlen (arg) != 0)
{
error_at (loc, "%<-gdwarf%s%> is ambiguous; "
"use %<-gdwarf-%s%> for DWARF version "
"or %<-gdwarf%> %<-g%s%> for debug level", arg, arg, arg);
break;
}
else
value = opts->x_dwarf_version;
This diagnostic looks wrong. It is probably missing the = between -gdwarf and
%s.
Since there is no test case for this invocation, I can only guess that it is
wrong.
