similar to: [LLVMdev] MC to LLVM disassembler?

I'm wondering if anyone is working on a machine code -> LLVM bitcode disassembler? Obviously, there won't be a one-to-one correspondence but it seems like you should be able to get close. There's always inline asm for the remaining fragments. So is there such a thing? Thank you, Bob

I built llvm-2.7 from source on FreeBSD-i386 with: ./configure --prefix=/opt && gmake It builds fine, but the Hello plugin fails to load with an unresolved symbol. $ opt -load /opt/lib/libLLVMHello.so -help Error opening '/opt/lib/libLLVMHello.so': /opt/lib/libLLVMHello.so: Undefined symbol "_ZNK4llvm4Pass5printERNS_11raw_ostreamEPKNS_6ModuleE" -load

This might be a very beginner question, but I'm looking for an example for something that I have never done. Suppose that I wanted to express actions with respect to lifted semantics of CPU instructions to an intermediate representation, BAP IL or LLVM IR. How might I go about providing a Backus Naur Form specification and then dynamically interpreting those lifted instructions by also

I don't have an android busybox handy, but I see similar on binaries compiled for ARMv7. The trick is to use: llvm-objdump -triple=armv7 -d whatever (ARMv7 covers virtually

Hi Evan, Thanks for the information! I've try to use llvm-objdump to disassemble some ARM binary, such as busybox in android. ./llvm-objdump -arch=arm -d busybox There are many instructions cannot decode, :./llvm-objdump: warning: invalid instruction encoding Did I use llvm-objdump in a correct way? I think that one possible reason is that llvm-objdump encounter pc relative data.

Hi Tim, Thanks a lot for the reply. I tested libc.so which is a shared library. llvm-objdump also report some disassemble errors. Could you please tell me more about $a, $t and $d symbols? How these symbols are used to define different regions? Where I can find this symbols in ELF object file? Thanks, David I'm now try to find a decoder of ARM instructions in oder On Thu, Jun 7, 2012

Hi, I'm considering to use MC disassembler for ARM target in a binary translation project. However after trying some ARM binary and I find that there are a lot of instructions that the disassembler fails to to decoding. Could anyone give me some information about the maturity of ARM disassembler? Thanks! David -------------- next part -------------- An HTML attachment was scrubbed... URL:

At the start of each range of ARM code, an assembler or compiler should produce a "$a" symbol with that address, and

The coding style I use for compiz is very similar to what's used in the xserver. This was the best I could get out of GNU indent. indent -psl -saf -sai -saw -sob -i4 -bbo -bls -lp -di1 -pcs -bs -cs -bl -bli0 -cdb -sc -bad -bap -l78 The style in compiz is slightly different though. Function parameters are aligned and I usually align function parameter names and variable names too. I also

That depends on how you define "one ARM instruction." It's not a clear cut thing. For example, is "add r1, r2, r3" the same ARM instruction as "add r1, r2, #4"? What is a distinct instruction and what's a variant encoding of the same instruction is often entirely a matter of convenience. -Jim On Jun 8, 2012, at 6:40 AM, Fan Dawei <fandawei.s at

Hi Tim, Thanks a lot for your help! I'm very grateful. libc.so is a prelinked library, I'll build a non-prelinked one and have another try. I'm now at the start of a binary translation project. I want to convert ARM binary code [*] to llvm ir, which is then translated to binary for our mips like architecture. That's why I'm looking for a decoder for ARM binary. The

Hi Jim, Thanks for reply. I'm sorry I didn't make myself clear enough. The MCInst created by MCDisassembler depends on the instructions defined in td files. These instructions do not have a one to one mapping to ARM instructions. There are usually one or more instructions defined in the td file correspond to one actual ARM instruction.

Hi, Is decompilation possible in general to the SSA form for binaries? I assume one has to make certain assumptions about code in general to get tools like these to work. For example if code like with dlsym or jit heap allocated functions can be incorporated at runtime it would seem that in general it is quite difficult to ascertain the boundaries of a basic block and insert the correct phi

Hi All, Is this possible to generate LLVM IR from any static/dynamic link library? I have some static and dynamic link library and I want to generate LLVM IR as I want to obfuscate these libraries. Is there any way to do the same. Please give me some pointers on this. Thanks, Deep -------------- next part -------------- An HTML attachment was scrubbed... URL:

This may be a dumb question, but here goes So I''m running on Puppet 3.1.1 on RHEL5, and i''ve been using Hiera since 2.5/2.6 ish and it''s been great!! I was reading up on Automatic Parameter Lookups and would love to use it for my modules. But I can''t seem to ever get Hiera/Puppet to load the value i''ve set in my yaml files. I feel like I must be
