Bug ID: 80552
Summary: Make consecutive relative line numbers more
maintainable
Product: gcc
Version: 7.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: testsuite
Assignee: unassigned at gcc dot gnu.org
Reporter: vries at gcc dot gnu.org
Target Milestone: ---
[ Spinoff from PR80221: "Contrib script to rewrite testcase from absolute to
relative line numbers" ]
We have patterns using relative line numbers in dg directives like this in
gcc/testsuite/obj-c++.dg/class-extension-2.mm:
...
@implementation MyObject2
@end /* { dg-warning "incomplete implementation of class .MyObject2." } */
/* { dg-warning "method definition for .-test. not found" "" { target
*-*-* } .-1 } */
/* { dg-warning "class .MyObject2. does not fully implement the
.MyProtocol. protocol" "" { target *-*-* } .-2 } */
/* { dg-warning "method definition for .-test2. not found" "" { target
*-*-* } .-3 } */
/* { dg-warning "class .MyObject2. does not fully implement the
.MyProtocol2. protocol" "" { target *-*-* } .-4 } */
/* { dg-warning "method definition for .-test3. not found" "" { target
*-*-* } .-5 } */
/* { dg-warning "class .MyObject2. does not fully implement the
.MyProtocol3. protocol" "" { target *-*-* } .-6 } */
...
A few ideas were generated in PR80221 to deal with this in a less verbose and
more maintainable fashion.

foobar;
/* { dg-warning "warning for foobar" continue }
{ dg-warning "another warning for foobar" continue }
{ dg-error "error for foobar" } */

foobar;
/* { dg-warning "warning for foobar" .-1 }
Bla, bla, reasoning.
{ dg-warning "another warning for foobar" continue }
Bla, bla, more reasoning.
{ dg-error "error for foobar" continue } */
