// clang-format off
// REQUIRES: lld, x86

// Test that we can display S_CONSTANT records.

// RUN: llvm-mc -filetype=obj -triple=x86_64-pc-win32 %p/Inputs/s_constant.s > %t.obj
// RUN: %build --compiler=clang-cl --nodefaultlib --mode=link -o %t.exe -- %t.obj
// RUN: env LLDB_USE_NATIVE_PDB_READER=1 %lldb -f %t.exe -s \
// RUN:     %p/Inputs/s_constant.lldbinit | FileCheck %s

// clang-cl cannot generate S_CONSTANT records, but we need to test that we can
// handle them for compatibility with MSVC, which does emit them.  This test
// case was generated by compiling this file with MSVC and copying the bytes
// that they emit for S_CONSTANT records.  Then we compile the same code with
// clang to get a .s file, and replace all S_LDATA32 records with the bytes from
// the S_CONSTANT records.  This way we end up with a .s file that contains
// symbol records that clang-cl won't generate.
