; Tests that `llvm-dis` could disassemble ThinLTO minimized bitcode
; (e.g., bitcode generated by `opt --thin-link-bitcode-file=<minimized-bitcode>`,
;  or `clang -Xclang -fthin-link-bitcode=<minimized-bitcode>`)

; %t.o is the thin-lto ready bitcode, and %t.thinlink.bc is the minimized bitcode.
; RUN: opt -thinlto-bc %s -thin-link-bitcode-file=%t.thinlink.bc -o %t.o

; With default options, `llvm-dis` returns invalid record for ThinLTO minimized bitcode.
; RUN: not llvm-dis %t.thinlink.bc 2>&1 | FileCheck %s --check-prefix=INVALID-RECORD

; INVALID-RECORD: Invalid record

; Tests that `llvm-dis` could disassemble minimized bitcode with `--print-thinlto-index-only`, and verify its content.
; RUN: llvm-dis --print-thinlto-index-only %t.thinlink.bc -o - | FileCheck %s --check-prefix=DIS
