<pre>Issue: When the first argument to _MoveToCoProcessor instrinsic is passed via a
parent function argument, it results in a compile error.
Compilation error: fatal error: error in backend: Cannot select: intrinsic
%llvm.arm.mcr
Clang Version:
clang version 3.5.0 (217039)
Target: armv7-none-linux-androideabi
Thread model: posix
Code (myfunc.cpp):
void MyFunc(const unsigned int x)
{
_MoveToCoprocessor(x, 2, 3, 4, 5, 6); // this doesn't compile
}
Compilation command:
%PATH%\clang++.exe -c myfunc.cpp -o myfunc.o -target
armv7-none-linux-androideabi -fms-extensions
The following code doesn't give a compile error:
const unsigned int x = 0; // this compiles fine
void MyFunc()
{
_MoveToCoprocessor(x, 2, 3, 4, 5, 6);
}
Thanks.</pre>
