The Error Message I receive is the following: "Instruction:1:1: error: invalid operand for instruction" I was using the MCAsmParser, with the RelaxAll Flag set to true, for the MCStreamer. Can someone clarify, as to why this is happening, or what I am missing? Thank you in advance.

I think a key point to understand is the MCStreamer interface, which has two implementations: one for object-file generation, and one for .s file generation. CodeGen/AsmPrinter can attach to either of these implementations. MCAsmParser will generally attach to the object-file version of MCStreamer. --paulr From: llvm-dev [mailto:llvm-dev-bounces at lists.llvm.org] On Behalf Of Craig Topper via llvm-dev Sent: Thursday, May 10, 2018 4:47 PM To: soham1 at bu.edu Cc: llvm-dev Subject: Re: [llvm-dev] Assembly file compilation flow P...

Hi everyone. We're interested in contributing a Hexagon assembler to MC and we're looking for comments on a good way to integrate the grammar in to the infrastructure. We rely on having a robust assembler because we have a large base of developers that write in assembly due to low power requirements for mobile devices. We put in some C-like concepts to make the syntax easier and this

Passing an assembly file to clang does not go through any CodeGen phases. It operates entirely in the MC layer. No MachineFunctions will be created. It just runs it through the MCAsmParser. Most of the setup for this is in clang's tools/driver/cc1as_main.cpp in the function ExecuteAssembler ~Craig On Thu, May 10, 2018 at 1:32 PM Soham Sinha via llvm-dev < llvm-dev at lists.llvm.org> wrote: > Hello, > > LLVM MC blog post > <http://blog.llvm.org/2010/04/in...

Hello, LLVM MC blog post <http://blog.llvm.org/2010/04/intro-to-llvm-mc-project.html> explains fairly well how the backend MC project is working. However, it's not clear to me how LLVM converts an assembly file (.s) to an object file. The driver --verbose option is not giving me much information as well. I want to know the flow. Like, What CodeGen phases does this file pass through? Is

As part of trying to fix PR30610 (ThinLTO with module inline asm), I wanted to add an assert that we have a Target and an MCAsmParser when we have non-null module inline asm in IRObjectFile::CollectAsmUndefinedRefs. Otherwise it silently fails to parse the module inline asm, which I initially found when trying to add an 'opt' based test for my fix (because 'opt' wasn't initializing asm parsers, something I am...

Hello, I am working on backend development and would like to utilize my target's MCAsmParser inside of an MCInst-level class implementation. I noticed that the AsmParser is registered with the target registry however I am having no luck grepping for a "template" of how to instantiate it and have yet to find specific documentation on how it is done. Any ideas or help is greatly ap...

Hi, I might just be doing something stupid, but when I do $ cmake -DCMAKE_INSTALL_PREFIX=/usr/local/llvm-2.8 -DCMAKE_BUILD_TYPE=Release .. $ sudo make install I don't get the expected headers in /usr/local/llvm-2.8/include/llvm It is simply an empty directory. What am I doing wrong? This is on Mac OS X, CMake 2.8+ Kind regards, Samuel
