## This checks for an issue with internal calls and BAT (BOLT address ## translation). BAT needs to map every output block back to an input ## block, but passes that introduce new blocks (such as validate ## internal calls) might create new blocks without a mapping to an ## input block. # REQUIRES: x86_64-linux,bolt-runtime # RUN: llvm-mc -filetype=obj -triple x86_64-unknown-unknown %s -o %t.o # Delete our BB symbols so BOLT doesn't mark them as entry points # RUN: llvm-strip --strip-unneeded %t.o # RUN: %clang %cflags %t.o -o %t.exe -Wl,-q # RUN: llvm-bolt --enable-bat %t.exe --relocs -o %t.out | FileCheck %s # CHECK: BOLT-INFO: Wrote {{.*}} BAT maps # RUN: llvm-bat-dump %t.out --dump-all | \ # RUN: FileCheck %s --check-prefix=CHECK-BAT-DUMP # CHECK-BAT-DUMP: BAT tables for {{.*}} functions .text .globl main .type main, %function .p2align 4 main: push %rbp mov %rsp,%rbp push %r12 push %rbx sub $0x120,%rsp mov $0x3,%rbx movq rel(%rip), %rdi .J1: cmp $0x0,%rbx je .J2 callq .J3 nopl (%rax,%rax,1) movabs $0xdeadbeef,%rax retq .J2: add $0x120,%rsp pop %rbx pop %r12 jmp .J4 .J3: pop %rax add $0x4,%rax dec %rbx jmp .J1 .J4: pop %rbp retq end: .size main, .-main .data rel: .quad end
