! Error test -- DO loop uses obsolete loop termination statement (warning)
|
|
! See R1131 and C1133
|
|
|
|
! By default, this is not an error and label do are rewritten to non-label do.
|
|
! A warning is generated with -pedantic
|
|
|
|
|
|
! RUN: %flang_fc1 -fdebug-unparse-with-symbols -pedantic %s 2>%t.stderr | FileCheck %s
|
|
|
|
! CHECK: end do
|
|
|
|
! The following CHECK-NOT actively uses the fact that the leading zero of labels
|
|
! would be removed in the unparse but not the line linked to warnings. We do
|
|
! not want to see label do in the unparse only.
|
|
! CHECK-NOT: do [1-9]
|
|
|
|
! RUN: FileCheck --check-prefix=ERR --input-file=%t.stderr %s
|
|
! ERR: A DO loop should terminate with an END DO or CONTINUE
