Overview

BiSheng compiler is developed based on the open-source LLVM. The frontend Clang of LLVM checks the syntax and conforms to language standards more strictly than GNU and Intel compilers. For details about common compatibility and portability problems of Clang, see the open-source official document at https://clang.llvm.org/compatibility.html. This section lists some BiSheng compiler compatibility problems in contrast with GNU and Intel compilers and some intrinsic procedures for reference. BiSheng compiler has achieved a certain level of compatibility with GNU and Intel compilers and provides the overall compatibility option -fGNU-compatibility for GNU compiler and the overall compatibility option -fIntel-Compatibility for Intel compiler.
