Regression test for using %{test} in (diff ...)
|
||
|
|
|
||
|
|
The action expander treats the second argument of diff? as "consuming
|
||
|
|
a target". Since targets needs to be known at rule creation time
|
||
|
|
rather than at rule evaluation time and dependencies are usually
|
||
|
|
evaluated at the latter stage, the below pattern could break if we
|
||
|
|
are not careful. We want to support it because it is a common pattern.
