// #define CRYPTOPP_DISABLE_MIXED_ASM 1
// Several compilers discard SIMD code that loads unaligned data. The symptom
// is often self test failures and UBsan findings for unaligned loads. For
// example, Power7 can load unaligned data using vec_vsx_ld but some versions
// of GCC and Clang require 16-byte aligned data when using the builtin.
// It is not limited to SSE and PowerPC code. Define this to disable
// Crypto++ code that uses potentially problematic builtins or intrinsics.
// Also see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=88234 and
// https://bugs.llvm.org/show_bug.cgi?id=39704
// #define CRYPTOPP_BUGGY_SIMD_LOAD_AND_STORE 1
// This list will probably grow over time as more compilers are identified.

// Define CRYPTOPP_NO_CXX11 to avoid C++11 related features shown at the
// end of this file. Some compilers and standard C++ headers advertise C++11
// but they are really just C++03 with some additional C++11 headers and
