@ REQUIRES: arm-registered-target

// Test that code symbols take priority over data symbols if both are
// defined at the same address during disassembly.
//
// In the past, llvm-objdump would select the alphabetically last
// symbol at each address. To demonstrate that it's now choosing by
// symbol type, we define pairs of code and data symbols at the same
// address in such a way that the code symbol and data symbol each
// have a chance to appear alphabetically last. Also, we test that
// both STT_FUNC and STT_NOTYPE are regarded as code symbols.

@ RUN: llvm-mc -triple armv8a-unknown-linux -filetype=obj %s -o %t.o
@ RUN: llvm-objdump --no-print-imm-hex --triple armv8a -d %t.o | FileCheck %s

// Ensure that all four instructions in the section are disassembled
// rather than dumped as data, and that in each case, the code symbol
// is displayed before the disassembly, and not the data symbol at the
// same address.
