----------------------------------------
Summary: Invalid function removal for eval input to pwrite/print
Key: SYSTEMML-2343
URL: https://issues.apache.org/jira/browse/SYSTEMML-2343
Project: SystemML
Issue Type: Bug
Reporter: Matthias Boehm
The following script fails with missing function and misleading error message.
The root cause is incorrect meta data management in the functional call graph
of IPA which did not properly detect eval functions under persistent writes or
print/tostring.
{code}
foo1 = function (matrix[double] M) return (matrix[double] ret) {
ret = M + 1
}
foo2 = function (matrix[double] M) return (matrix[double] ret) {
ret = M + 2
}
M = matrix ("1 2 3 4 5 6", rows=3, cols=2)
A = eval("foo1", M)
B = eval("foo2", A)
print ("A = \n" + toString(A))
print ("B = \n" + toString(B))
{code}
{code}
