; Test to ensure that the LTO pipelines add pass to build the TargetLibraryInfo
; using the specified target triple.
; Check with regular LTO
; RUN: llvm-as < %s >%t1
; RUN: llvm-lto -exported-symbol=main -o %t2 %t1
; RUN: llvm-nm %t2 | FileCheck %s
; Check with ThinLTO. Use llvm-lto2 since this adds earlier passes requiring
; the TargetLibraryInfo with ThinLTO (WholeProgramDevirt).
; RUN: opt -module-summary -o %t1 %s
; RUN: llvm-lto2 run -r %t1,main,plx -o %t2 %t1

; We check that LTO will be aware of target triple and prevent exp2 to ldexpf
; transformation on Windows.
