similar to: [LLVMdev] How to output a .S *and* a .OBJ file?

llvm-dev, Thanks so much in advance for any help, tips, or advice you may be able to offer me. I'm going to try to avoid the big-picture description of the project I'm working on, and only talk about the parts that I have trouble with / currently need to implement. -- I've been starting by taking the source code from the "llvm-mc" tool, and working that down into a

Hi, My apologies if this appears to be a very trivial question -- I have tried to solve this on my own and I am stuck. Any assistance that could be provided would be immensely appreciated. What is the absolute bare minimum that I need to do to disassemble an array of, say, ARM machine code bytes? Or an array of Thumb machine code bytes? For example, I might have an array of unsigned chars -- how

Hi Aiden, The easiest thing I can do is to point you to the source of the "llvm-mc" tool, which does exactly what you ask in its "-disassemble" mode. The code is rather small, so it should be easy to work out. tools/llvm-mc Cheers, James -----Original Message----- From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] On Behalf Of Aidan Steele Sent:

Hi Aiden, The 'C' based interface you could use in is llvm/include/llvm-c/Disassembler.h, which in there is: /** * Disassemble a single instruction using the disassembler context specified in * the parameter DC. The bytes of the instruction are specified in the * parameter Bytes, and contains at least BytesSize number of bytes. The * instruction is at the address specified by the

Hi Kev and James, Thanks to both of you for responding. I had looked at the otool release published for 10.7.2 (cctools-800), but it seems that it only snuck in after that and by the cctools-809 release! In any case, both that and llvm-mc should be more than adequate! A follow-up question: is the C interface to LLVM a second-class citizen or should I reasonably be able to expect to do everything

Attached is a working patch set for llvm to be able to emit arm64 (currently as triple aarch64-apple-ios) mach-o object files, in case someone is interested. I'm not sure if the llvm maintainers want the patch given the previous message that there's going to be an official patch set from apple to support this, but here is mine. What works (tested on an iPhone 5S): * objc strings,

Ping, Apart from Anton's concerns (which I think are manageable) and Micah's support, I received no reply on this. Does there exist a way to tell MC to generate and ELF container for code on Windows? If not, I'm willing to submit a patch to fix this, but would like some opinions on the best direction to take here. The proposed "llvm::TargetSpec class"

Hi, I have been trying to use LLVM as a disassembler, thus providing a small part of my decompiler that I am working on. It currently decompiles from X86_64 binary.o -> LLVM IR. It works with a small set of test programs so far, so cannot currently handle large binary programs yet. The problem is with the LLVM "getInstruction()" method. It used to have a PC (program counter)

Hi All, While trying to put together an MC-based assembler the other day, I again encountered MC's non-obvious memory ownership rules. The most egregious example of these is MCObjectStreamer's destructor: MCObjectStreamer::~MCObjectStreamer() { delete &Assembler->getBackend(); delete &Assembler->getEmitter(); delete &Assembler->getWriter(); delete Assembler;

Hi, > Would it be OK to add "ELF" to Triple::EnvironmentType? It seems like a plausible choice since MachO is there. On the other hand, I'm not sure whether it makes sense to make it mutually exclusive with the other members of EnvironmentType (GNU, GNUEABI, EABI). EABI and GNUEABI imply ELF. GNU in practice does not need to imply ELF, but is used in the ARM world as "the

I can use llc to compile my IR module to amdgcn with some non-zero output. However, if try to write the output (assembly or object) to a string (via buffer_ostream) the resulting string has always zero length. Here the code changes I do: Original llc:       if (Target->addPassesToEmitFile(PM, *OS,                                       DwoOut ? &DwoOut->os() : nullptr,

Hello, My question in 2 words is the following: Is it mandatory to generate host keys on the target host, or can they be generated on another host and transfer to thetarget host ? If my question is not clear here is an example... I need to install host keys on a host server. I imagine the usual way is to launch the following command locally on the host server . # ssh-keygen -t rsa1

This patch refactors the data transfer code with several goals: * Have a common read(source)/write(target) loop so that common processing can happen in the middle of it, e.g. format change/progress bar * Provide volume metadata to transfers to allow smarter reading/writing, e.g. of sparse files * Simplify the data transfer code The patch *isn't* NFC because there are some minor behaviour

Hi, In the document: http://llvm.org/docs/WritingAnLLVMBackend.html described example like: SparcTargetAsmInfo::SparcTargetAsmInfo(const SparcTargetMachine &TM) { Data16bitsDirective = "\t.half\t"; Data32bitsDirective = "\t.word\t"; Data64bitsDirective = 0; // .xword is only supported by V9. ZeroDirective = "\t.skip\t"; CommentString = "!";

Hello Tim, Rafael, Renato and llvmdev, I’m working to get llvm-objdump handle both arm and thumb disassembly from the same object file similarly to how darwin’s otool(1) works. And I’m looking for implementing direction. I spoke to Jim Grosbach about some ideas and he suggested I send out and email about some of the possibilities. Since none of the ones I could think of are pretty he thought

Hi Daniel, attached is a patch that pushes most of the object file specific parsing out of AsmParser and down into MachOAsmParser. This was done as a cleanup for the ELF work. I know that you're not happy with this approach, particularly the fact that as we add more object file formats and assembler dialects, it's going to cause a class explosion. But I was hoping that we could use this
