Phantom.JIT

Phantom.Code extension providing Just-In-Time asm x64 compilation based on LLVM (see my related project LLVM JIT PDB for how on-the-fly PDB debugging is done inside LLVM).

Installation

• Download, clone or fork Phantom and Phantom.Code.
• Copy (or mklink) every content of this repo, same as for the Phantom.Code repo, to your Phantom folder.
• Get LLVM 11.0
• Get LLVM JIT PDB and follow the instructions in the README to integrate it to the LLVM build pipeline
• Use CMake to generate the LLVM.sln inside %YOUR_LLVM_PATH%/build/vs20XX (XX depending on your Visual Studio version year number, ex: vs2019).
• Check you have the LLVMJITPDB project inside LLVM.sln/Libraries
• Build LLVM.sln/Libraries folder, either using Debug or RelWithDebInfo configurations (no Release, or you'll need to modify the Phantom.JIT.premake.lua)
• Open a cmd with administrator rights in %YOUR_PHANTOM_PATH%/dependencies
• Run into the cmd mklink /D LLVM %YOUR_LLVM_PATH% to create a link to LLVM inside the dependencies folder of Phantom
• Run (again) the Premake-vs20XX.bat in the Phantom folder
• NOTES :
  • To build LLVM somewhere else, edit Phantom.JIT.premake.lua
  • You can directly download LLVM into %YOUR_PHANTOM_PATH%/dependencies/LLVM and skip the cmd/mklink part above

Running

Just explore, compile, run HelloWorld.JIT sample, insert breakpoints inside the HelloWorld.Jit.cpplite file and see how it works ! Have fun !
