# In python's re.sub patterns, '%{3}' means three '%%%'. If we permitted that | |
# as a substitution name (and escaped it before recording it as a | |
# substitution), it would be confusing if someone tried to use the same name in | |
# a lit configuration file, where the pattern isn't escaped automatically. | |
# DEFINE: %{3} = value | |
# RUN: echo %{3} | |
# CHECK: Substitution name '%{3}' is malformed {{.*}} | |
# CHECK-NEXT: in {{DEFINE}}: directive on test line [[#@LINE-4]] | |
# CHECK: Unresolved: 1 {{\([0-9]*.[0-9]*%\)}} |
