Just did a quick test. Correct myself previously. Those lines also needs to be removed since they are XPASS now.
However the real issue is the dg-note at Line 32, that is the warning disappeared. diff --git a/libgomp/testsuite/libgomp.oacc-fortran/privatized-ref-2.f90 b/libgomp/testsuite/libgomp.oacc-fortran/privatized-ref-2.f90 index 498ef70b63a..8cf79a10e8d 100644 --- a/libgomp/testsuite/libgomp.oacc-fortran/privatized-ref-2.f90 +++ b/libgomp/testsuite/libgomp.oacc-fortran/privatized-ref-2.f90 @@ -29,16 +29,10 @@ program main implicit none (type, external) integer :: j integer, allocatable :: A(:) - ! { dg-note {'a' declared here} {} { target *-*-* } .-1 } character(len=:), allocatable :: my_str character(len=15), allocatable :: my_str15 A = [(3*j, j=1, 10)] - ! { dg-bogus {'a\.offset' is used uninitialized} {PR77504 etc.} { xfail *-*-* } .-1 } - ! { dg-bogus {'a\.dim\[0\]\.lbound' is used uninitialized} {PR77504 etc.} { xfail *-*-* } .-2 } - ! { dg-bogus {'a\.dim\[0\]\.ubound' is used uninitialized} {PR77504 etc.} { xfail *-*-* } .-3 } - ! { dg-bogus {'a\.dim\[0\]\.lbound' may be used uninitialized} {PR77504 etc.} { xfail { ! __OPTIMIZE__ } } .-4 } - ! { dg-bogus {'a\.dim\[0\]\.ubound' may be used uninitialized} {PR77504 etc.} { xfail { ! __OPTIMIZE__ } } .-5 } call foo (A, size(A)) call bar (A) my_str = "1234567890" After the change, all the tests are passed. However, is that right? I am not familiar with either Fortran or libgomp, but the warning like something declared here which might report variable declaration conflict seems needed.

The problem is that specific warning test.
