; This test case has two scops in a row. When code generating the first scop,
|
|
; the second scop is invalidated. This test case verifies that we do not crash
|
|
; due to incorrectly assuming the second scop is still valid.
|
|
|
|
; We explicitly check here that the second scop is not code generated. Later
|
|
; improvements may make this possible (e.g., Polly gaining support for
|
|
; parameteric conditional expressions or a changed code generation order).
|
|
; However, in case this happens, we want to ensure this test case is been
|
|
; reasoned about and updated accordingly.
