undeclared identifier with xmmintrin.h

[ScottDillman]

I'm actually having problems with this header being included somewhere deep down in the project hierarchy, but paired the problem down to a simple example.

#include <x86intrin.h>

int main(int argc, char *argv[])
{
    return 0;
}

executing the following command line:

cldoc generate -m64 -I/usr/lib/llvm-3.6/lib/clang/3.6.2/include -- --type html --loglevel info --language c++ test.cpp --output ./test

generates the following errors:

Could not generate documentation due to parser errors

Executing clang like the following:

clang -I/usr/lib/llvm-3.6/lib/clang/3.6.2/include test.cpp  

builds cleanly..

I'm relatively new to clang so it could be operator error, but scouring the usual sources for solutions turned up nothing

I discovered I have clang 3.6 installed and added '3.6' to the array here:

https://github.com/jessevdk/cldoc/blob/master/cldoc/tree.py#L53

which solved the problem..

All recent versions of clang are now added in the search for the library. This issue should be resolved.
