Summary: Anders pass asserts on extractvalue/insertvalue
Product: libraries
Version: trunk
Platform: All
OS/Version: All
Status: NEW
Severity: normal
Priority: P2
Component: Interprocedural Analyses
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
CC: [email protected]
Very easy to reproduce: Feed any program containing a insertvalue or
extractvalue to Anders AA pass, and it asserts. These instructions were
recently added (for the "first class aggregate" feature), but no one told
anders about them yet.
Also see bug #2451, which is the same bug, but for the vector insert/extract
instructions.
Using a testcase from InstCombine, we can easily check this:
llvm-as < test/Transforms/InstCombine/extractvalue.ll | opt -anders-aa
-disable-output
Unknown instruction: %s1.1 = insertvalue { i32, i32 } undef, i32 0, 0
; <{ i32, i32 }> [#uses=1]
