Just updated the source and now I get the unreachable error again. The JIT doesn't know how to handle a RAUW on a value it has emitted. UNREACHABLE executed at /home/conrado/engines/llvm/lib/ExecutionEngine/JIT/JITEmitter.cpp:1542! I think that it's not helpful now, but I can post the program, if you want me to.

Great! It just worked. I was a bit worried about using pointers to call functions because it's a little too overwhelming in a big project, I think. Just for the record, if the function code isn't freed with freeMachineCodeForFunction, I get a segmentation fault during recompileAndRelinkFunction with this stack dump: Running pass 'X86 Machine Code Emitter' on function

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

Hi there. I was trying to rebuild LLVM, this time with Clang, and after getting the last svn version, I got this error during cmake: CMake Error: Error in cmake code at <dir>/llvm/projects/CMakeLists.txt:7: Parse error. Function missing ending ")". Instead found left paren with text "(". The line is "if(NOT (${entry} STREQUAL

Hm, I wonder if the error message for llvm_unreachable should change. I think I remember a couple people focusing incorrectly on the UNREACHABLE instead of the actual error message above it (which means it's our fault, not theirs). Miranda, this is pointing at the same problem you had before. You have a function JIT-compiled, and you're trying to RAUW (ReplaceAllUsesWith) it. You'll

Hi, Here's one of my proposals for GSoC 2012. What do you think? Chip Project Title: Table-Driven Decompilation Abstract: Over the years, the LLVM family has grown to include nearly every type of build tool in existence. One of the few missing is a decompiler. LLVM's TableGen tool could potentially accelerate development of such a tool; most backends already have the information needed

Hi, I recently downloaded and installed the libcpu package (from http://libcpu.org ) that uses llvm as the backend on my linux machine. I have a piece of Motorola 88100 code (essentially the output of the 176.gcc benchmark from SPEC CPU 2000) that I am trying to run using this emulator, but I am running into errors when trying to run it. Has anyone been able to successfully use the m88k

Hi there! In the x86 disassembler I noticed an if-statement with a duplicated branch. Are these intended to be identical?

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:
