#ifndef _rustc_llvm_SuppressLLVMWarnings_h
#define _rustc_llvm_SuppressLLVMWarnings_h
// LLVM currently generates many warnings when compiled using MSVC. These warnings make it difficult
// to diagnose real problems when working on C++ code, so we suppress them.
#ifdef _MSC_VER
#pragma warning(disable:4530) // C++ exception handler used, but unwind semantics are not enabled. Specify /EHsc
#pragma warning(disable:4624) // 'xxx': destructor was implicitly defined as deleted
#pragma warning(disable:4244) // 'initializing': conversion from 'xxx' to 'yyy', possible loss of data
#endif
