Compilation works on Linux (LLVM 15)

[mrexodia]

Just some local experiments in a Docker image if anyone is interested (not ready for merging obviously)...

[mrexodia]

Unfortunately this crashes right away when lifting a mov instruction: 140001000 4889c8 mov rax, rcx

liftme.exe.zip

I'll have to compile this with address sanitizer and see what's going on in more detail...

Only reason I could think is apparently I havent implement jnb instruction, its implemented now and binary is lifted on windows correctly right now.

[mrexodia]

Yeah it doesn’t even get there, it crashes in the mov right away with some memory corruption error on the command line. I’ll investigate it properly tomorrow and see what could be going on. My LLVM is also at 15, so that might be an issue as well…

I figured out it crashes, can you update to latest version so I can merge your branch?

[mrexodia]

Yes, I will rebase it!

[mrexodia]

Done, I rebased on the latest development branch and removed the CMake changes. I think the CMake needs to be rewritten fully, but I don't have time for this now...

Currently this will not compile, because you need to add linux-pe to the project yourself. Feel free to push and update to my branch in a way that works for you. Locally it looks something like this for me:

include(FetchContent)

# Fix warnings about DOWNLOAD_EXTRACT_TIMESTAMP
if(POLICY CMP0135)
	cmake_policy(SET CMP0135 NEW)
endif()
message(STATUS "Fetching linux-pe (58249d9)...")
FetchContent_Declare(linux-pe
	GIT_REPOSITORY
		"https://github.com/can1357/linux-pe"
	GIT_TAG
		58249d9
)
FetchContent_MakeAvailable(linux-pe)

message(STATUS "Fetching Zydis (v4.1.0)...")
FetchContent_Declare(Zydis
	GIT_REPOSITORY
		"https://github.com/zyantific/zydis"
	GIT_TAG
		v4.1.0
)
FetchContent_MakeAvailable(Zydis)

And then:

target_link_libraries(lifter PRIVATE
	Zydis
	linux-pe
)

The crash isn't fixed though, but I will debug it more next week...

LGTM, I'll push the commit to fix the crash in a bit. Thanks for your contributions!
