Either OCaml or Haskell would be a good choice. Why not check out the LLVM tutorials for each language? The LLVM tutorial for OCaml is here: http://llvm.org/docs/tutorial/OCamlLangImpl1.html Haskell has more momentum these days, but there are plenty of good parsing libraries for OCaml as well including the PEG parser generator Aurochs, Menhir, and the GLR … Read more
mcsema is a production-quality binary lifter. It takes x86 and x86-64 and statically “lifts” it to LLVM IR. It’s actively maintained, BSD licensed, and has extensive tests and documentation. https://github.com/trailofbits/mcsema
The exact line to write in your ~/.lldbinit file is settings set target.x86-disassembly-flavor intel In the future, you will also be able to tweak how immediate values are displayed with the new settings: target.use-hex-immediates and target.hex-immediates-style.
You can build your project with -fsanitize=address -fsanitize-recover=address flags, and run with environment variable ASAN_OPTIONS=halt_on_error=0. Source: https://github.com/google/sanitizers/wiki/AddressSanitizer
Eli’s answer is great, but it’s missing the final part, which is getting the integer back. The full picture should look like this: if (ConstantInt* CI = dyn_cast<ConstantInt>(Val)) { if (CI->getBitWidth() <= 32) { constIntValue = CI->getSExtValue(); } } Of course, you can also change it to <= 64 if constIntValue is a 64-bit integer, … Read more
I have high hopes for it. This is being worked on by several people from Google. Seeing as how the BDFL is also employed there, this is a positive. Off the bat, they state that this is a branch, and not a fork. As such, it’s within the realm of possibility that this will eventually … Read more
1) To the best of my knowledge as of early Nov, 2017 you are correct: there is no commonly available way to compile Swift to WebAssembly. Maybe some enterprising hacker somewhere has made it happen but if so she hasn’t shared her code with us yet. 2) In order to enable Wasm support you will … Read more
The library requiring the symbols is included by -lLLVMSupport, so -ldl must come after -lLLVMSupport. I changed this: `llvm-config –ldflags –libs core` To this: `llvm-config –libs core` `llvm-config –ldflags` And the linker was successful.
