Bug ID: 15937
Summary: MIPS backend generates wrong code for vector icmp fed
into sext
Product: new-bugs

OS: Linux

Minimal LLVM-IR test case
The MIPS backend does not handle vectors correctly when the result of an icmp
operation is then sign-extended. Essentially, the sign-extension is being
dropped. Wrong behavior requires an LLVM vector, and sext by itself seems to
work fine. Minimal test case attached.
