- gcc - What exactly is LLVM? - Stack Overflow
An LLVM-based compiler: This is a compiler built partially or completely with the LLVM infrastructure For example, a compiler might use LLVM for the frontend and backend but use GCC and GNU system libraries to perform the final link
- How to detect LLVM and its version through #define directives?
0 Similarly to semequ solution, we can build macros that will detect the LLVM clang version while using Apple clang by directly leveraging the Wikipedia data (which is built on the CMakeLists of the llvm-project, like this one)
- How to list supported target architectures in clang?
Clang is essentially just a C to LLVM translator, and it's LLVM itself that deals with the nitty-gritty of generating actual machine code, so it's not entirely surprising that Clang isn't paying much attention to the underlying architecture As others have already noted, you can ask llc which architectures it supports
- llvm - How to automatically register and load modern Pass in Clang . . .
I'm trying to write a simple "modern" LLVM pass and use it with Clang I want it to be able to be run with a command like: clang -Xclang -load -Xclang libMyPass so file cpp There are a lot of manu
- Switching between GCC and Clang LLVM using CMake
I have a number of projects built using CMake and I'd like to be able to easily switch between using GCC or Clang LLVM to compile them I believe (please correct me if I'm mistaken!) that to use Cl
- What is the difference between clang (and LLVM) and gcc g++?
LLVM is, perhaps, two things then LLVM-the-machine, which is the type system and instruction set, which is probably better referred to as "LLVM IR"; and LLVM-the-API, which is software for manipulating code in the LLVM IR, such as the LLVM JIT compiler, or perhaps the LLVM x86 machine code backend
- llvm: How to get the label of Basic Blocks - Stack Overflow
Values in LLVM IR are not required to have a name; and indeed, those basic blocks don't have names, which is why you get an empty string from currBB->getName() The reason that they have names in the LLVM IR printout is because when you print to the textual format of LLVM IR (as it appears in ll files), you have to assign a name to them to make them referable, so the printer assigns
- How to make clang compile to llvm IR - Stack Overflow
I want clang to compile my C C++ code to LLVM bitcode rather than a binary executable How can I achieve that? And if I have the LLVM bitcode, how can I further compile it to a binary executable? I
