bolt/test/AArch64/inline-bti.s

## This test checks that for AArch64 binaries with BTI, we do not inline blocks with indirect tailcalls.

# REQUIRES: system-linux

# RUN: llvm-mc -filetype=obj -triple aarch64-unknown-unknown %s -o %t.o
# RUN: %clang %cflags -O0 %t.o -o %t.exe -Wl,-q -Wl,-z,force-bti
# RUN: llvm-bolt --inline-all %t.exe -o %t.bolt  | FileCheck %s

# For BTI, we should not inline foo.
# CHECK-NOT: BOLT-INFO: inlined {{[0-9]+}} calls at {{[0-9]+}} call sites in {{[0-9]+}} iteration(s). Change in binary size: {{[0-9]+}} bytes.
