Hints and Advice

+ +

The generated LLVM code will be easier to read if +you use stdio (e.g., printf) than iostreams (e.g., std::cout).
Unused inline functions and methods are not generated. Instead +of 'class foo { void bar() {}};', +try writing 'class foo { void bar(); }; void foo::bar() {}'.
If you want to try out a file that uses non-standard header files, you should + preprocess it (e.g., with the -save-temps or -E options to + gcc) then upload the result.

+ + +

Demangle C++ names with C++ filt

+ +

+Select this option if you want to run the output LLVM IR through "c++filt", +which converts 'mangled' C++ names to their unmangled version. +Note that LLVM code produced will not be lexically valid, but it will +be easier to understand. +

+ +

Run link-time optimizer

+ +

+Select this option to run the LLVM link-time optimizer, which is designed to +optimize across files in your application. Since the demo page doesn't allow +you to upload multiple files at once, and does not link in any libraries, we +configured the demo page optimizer to assume there are no calls +coming in from outside the source file, allowing it to optimize more +aggressively.

+ +

Note that you have to define 'main' in your program for this +to make much of a difference. +

+ +

Show detailed pass statistics

+ +

+Select this option to enable compilation timings and statistics from various +optimizers.

+ + +

Analyze generated bytecode

+ +

+Select this option to run the llvm-bcanalyzer tool +on the generated bytecode, which introspects into the format of the .bc file +itself.

+ + +

Show C++ API code

+ +

+Select this option to run the llvm2cpp tool +on the generated bytecode, which auto generates the C++ API calls that could +be used to create the .bc file. +
