How to use this tool compile solidity/evm bytecode into llvm ir?

[ttiinn]

Hi, sorry to bother.
I'm wonder is this the right way to use this tool?

~/evmjit/build/cpp-ethereum/build/test$ EVMJIT="-help" ./testeth --jit

I got some unexpected feedback

Running tests using path: "/home/user0/tests"
An unrecognized parameter in the argument jit

Usage: testeth [Boost.Test argument]... -- [custom test module argument]...

For detailed help on Boost.Test parameters use:
  testeth --help
or
  testeth --help=<parameter name>

The Readme file is a little difficult for me to understand. I'll be really appreciated if anyone can help.

EVMJIT="-help" ./testeth -- --vm jit

And use EVMJIT="-dump" to dump generated LLVM IR.

Hi~May i ask you how did you build this project? on x86 or x64? use visual studio 2015 or 2017? how about your building system(Linux or Win)?
Sorry for so many questions, i have some problem when i build and i want to check my environment : ).

in linux.

EVMJIT is a submodule of testeth. You can build testeth with EVMJIT option on(open it in ../testeth/cmake/EthOptions.cmake)
Testeth build guide: https://github.com/ethereum/testeth

After build it successfully testeth is in the path: ../testeth/build/test

Thx , it helped a lot. I have built the whole testeth, and it works when i type
EVMJIT="-help" ./testeth -- --vm jit
But actually i want to compile my own solidity bytecode into LLVM bitcode. I have searched testeth docs but it is difficult for me. Is there any way can set the compile path to my code?

I'm not sure what you want to do with that, but some important information.

1. EVMJIT is not maintained any more, so you cannot build the latest Aleth with it.
2. You could select evmjit in aleth-vm to execute any EVM bytecode: aleth-vm --vm jit.
3. Combined with -dump flag you could print the LLVM IR code: EVMJIT=-dump aleth-vm --vm jit.
4. You will not get 1 to 1 mapping of Solidity code. In the LLVM IR there is a lot of runtime helper functions and probably solidity also generates some additional EVM code even for empty contract.

Hello, I wanted to convert my own etherum bytecode to llvm ir. Can you guide me about how to use this tool and the other tool - aleth mentioned in the above chat.
