                    language flags -fprofile-instr-generate
                    -fcoverage-mapping
           Product: tools
           Version: trunk
          Hardware: All
                OS: All

=====================================================================
ERROR SCENARIO

 clang --version
==============================
Chromium OS 9.0_pre353983_p20190325-r19 clang version 9.0.0
(/var/cache/chromeos-cache/distfiles/host/egit-src/llvm-project
de7a0a152648d1a74cf4319920b1848aa00d1ca3) (based on LLVM 9.0.0svn)
Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin


My test code is –cat test.cc 
===========================================
#include<iostream>
using namespace std;
int main()
{
cout << "Hello World\n";
return 0;
}

Compiler the code using the below command
==============================================
clang++ -Wall -fprofile-instr-generate -fcoverage-mapping test.cc -o test

In the above command both the flags are required because I want to generate
code coverage report.
-fprofile-instr-generate -fcoverage-mapping 

Below is the ERROR Message
=======================================
fatal error: error in backend: Cannot select: intrinsic
%llvm.instrprof.increment

WORKING SCENARIO

Another system where clang++ version is shown below
clang++ --version
Chromium OS 9.0_pre353983_p20190325-r1 clang version 9.0.0
(/var/cache/chromeos-cache/distfiles/host/egit-src/clang.git

Target: x86_64-pc-linux-gnu
Thread model: posix
InstalledDir: /usr/bin

Source code and compilation step is same. Build successfully and object is
created.
