# This test checks that for AArch64 binaries with BTI, we do not inline blocks with indirect tailcalls.
# Same as inline-bti.s, but checks the debug output, and therefore requires assertions.
# REQUIRES: system-linux, assertions
# 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 --debug 2>&1 | FileCheck %s
# For BTI, we should not inline foo.
# CHECK: BOLT-DEBUG: Skipping inlining block with tailcall in _Z3barP1A : .LBB01 to keep BTIs consistent.
# 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.
