llvm/test/CodeGen/X86/large-eh-encoding.ll

; Test that --large-eh-encoding uses 8-byte encodings for personality, LSDA,
; and TType in x86_64 ELF targets.

; Default (small code model, no flag): sdata4 encodings
; RUN: llc -mtriple x86_64-pc-linux-gnu -code-model=small < %s | FileCheck %s --check-prefix=DEFAULT
; RUN: llc -mtriple x86_64-pc-linux-gnu -code-model=small -relocation-model=pic < %s | FileCheck %s --check-prefix=DEFAULT-PIC

; With --large-eh-encoding: sdata8 encodings
