Hi, Julian,

In total there are two errors in this file. Apart from the invocation of removed function "MaybeReexec", this file also misses a header file "sanitizer_common/sanitizer_interface_internal.h".
I have attached the compiler's error message in the following section for your reference.

/llvm-project/compiler-rt/lib/tsan/rtl-old/tsan_rtl.cpp:212:12: warning: variable 'i' set but not used [-Wunused-but-set-variable]

for (int i = 0;
         ^

/llvm-project/compiler-rt/lib/tsan/rtl-old/tsan_rtl.cpp:419:3: error: use of undeclared identifier 'MaybeReexec'

MaybeReexec();
^

/llvm-project/compiler-rt/lib/tsan/rtl-old/tsan_rtl.cpp:437:3: error: use of undeclared identifier '__sanitizer_set_report_path'

__sanitizer_set_report_path(common_flags()->log_path);

Add include

H @lechenyu, thanks for helping out! :)

this file also misses a header file "sanitizer_common/sanitizer_interface_internal.h".

This probably means that rtl-old is unused / bit rotting in more than one way. AFAIK, I didn't add this dependency in D129157.

I still added the #include, but it probably means we should remove rtl-old sooner than later.

@lechenyu: do you mind signing off on this?

I am sorry I forget to send you the confirmation. I have tested this patch last week and it did fix the issue.

compiler-rt/lib/tsan/rtl-old/tsan_rtl.cpp

void Initialize(ThreadState *thr) {
   CacheBinaryName();
   CheckASLR();
   InitializeFlags(&ctx->flags, options, env_name);
   AvoidCVE_2016_2143();
   __sanitizer::InitializePlatformEarly();
   __tsan::InitializePlatformEarly();
 
 #if !SANITIZER_GO
-  // Re-exec ourselves if we need to set additional env or command line args.
-  MaybeReexec();
-
   InitializeAllocator();
   ReplaceSystemMalloc();
 #endif
   if (common_flags()->detect_deadlocks)
     ctx->dd = DDetector::Create(flags());
   Processor *proc = ProcCreate();
   ProcWire(proc, thr);
   InitializeInterceptors();
