Bug ID: 25458
Summary: [Polly] Timeout during scop construction due to overly
complex sets being formed
Product: Projects
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Polly

Test case
Polly with 252451 times out when running polly-opt -polly-process-unprofitable
timeout.ll
It seems that the sets we are creating during scop construction are becoming
very complex. We could probably timeout on this, but my feeling is that at
least for this test case we should be able to compute the scop represenation
more efficiently?
