![]() ![]() Related Question Should I use GCC or clang? Why does Apple use Clang? Clang is mainly used to provide performance superior to that of GCC. Clang is a C, C++, Objective-C, or Objective-C++ compiler that is compiled in C++ based on LLVM and released under the Apache 2.0 license. GCC is a program language compiler developed by GNU. However the advantage of using Clang is about much more than just speed. Apple claims that the Clang parser is 3x faster than GCC for debug builds whilst maintaining compatibility with GCC. ![]() It uses the Clang frontend and LLVM backend optimizer and code generator. And at each optimization level GCC now beats Clang by 17%. GCC more than reverses Clang's former superiority. Good, but at each optimization level GCC's 619 build is more than twice as fast as its 301. How many optimization levels are there in GCC?Īt -O2 optimization Clang's 619 build is 46% faster than its 301 build: at -O3 Clang's improvement is 31%.How do I use GCC instead of clang on Mac?.What is difference between G ++ and GCC?.I haven't been able to find a 64-bit cross-compiler for Mac. $ yum install mingw64-gcc mingw64-g++ mingw64-zlibīest bet for cross-compiling seems to be Fedora, which gives you both mingw32 and mingw64: To install mingw64, follow the instructions at: On Fedora, you can install mingw32 using standard yum. On Ubuntu, you can get going in many cases with "apt-get install gcc-mingw32" ![]()
