Bug ID: 20571
Summary: FileCheck should clear variables on CHECK-LABEL
Product: Test Suite
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: lit
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
Currently a variable captured before a CHECK-LABEL can match an attempted use
in a following label. This can result in unintended matches in what should be
an unrelated segment of code
; CHECK-LABEL: @func1
; CHECK: MOV [[FOO:1234]]
; CHECK: STORE [[FOO]]
; CHECK-LABEL: @func2
; CHECK: STORE [[FOO]] // Should be considered an undefined variable, but it
will match
