clang vs gcc

Clang advantages over the GCC compiler:Faster compile timesLess compile outputThe error prompt is more friendly , such as clang can directly indicate a relatively simple error location and the way it "thinks" in the compilation process.built-in static analysis tools allow static analysis of code (CLANG-ANALYZE). That's

Most of the time, there are some similar to the compiler, such as GNU,GCC,CLANG,LLVM and other nouns, are not very clear what it is to do, understand these things, for many of the configuration of Xcode needs to be modified to be handy, so it is necessary to understand their direct relationship and differences.1 GUN"GNU, named from GNU's not Unix abbreviation, a UNIX -like operating system , driven by the G

If this is still more abstract, the introduction of the next Clang will know: Clang is a C + + written, based on LLVM, released under the LLVM BSD license c/c++/objective c/objective C + + compiler, its goal (one) is beyond GCC 。LLVM historyApple has been using GCC as the of

The main collation of a discussion on self-knowledge: Currently the industry's three major C + + compilers: visualc++, g++, clang++. visualc++ The main advantage is the graphical interface, debugging is convenient, but the available platform is very limited. This is mainly compared to g++ and clang++. the advantages of clang than

Label: GCC clang blocking warning wtrigraphs Generally, a considerable amount of warning information is generated during code compilation, especially when the-wall option is used. -Wall does not open all warnings as it literally means. however, it has opened a lot of warnings. we can certainly block warnings that we know are "harmless" but still print out to occupy poor console space.

1 OverviewValgrind can effectively monitor most of the memory problems, you can't help but think, since the C + + memory problem is so common, why not add the memory problem detection function in the compiler? Unfortunately, the GCC also does not currently support memory detection, it is gratifying that clang support. Here we see how to use Clang to discover memo

of well-defined interfaces, which makes the front-end design of the compiler Quite dumb. We can write a front-end of llvm for Perl, which can compile and run the binary code at a cost. It can compile a front-end for python. Do not think how complicated the front-end is. It is not very difficult to use llvm's reasonable interface. So in general, the llvm/clang architecture is better than the GCC architectur
