similar to: Adding assembly instructions to LLVM

https://bugs.freedesktop.org/show_bug.cgi?id=98506 Bug ID: 98506 Summary: Pagefault in gf100_vm_flush Product: xorg Version: git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Driver/nouveau Assignee: nouveau at lists.freedesktop.org

Hello; I was planning to add a new instruction to the LLVM IR (and later to MIPS backend) for TLS(Thread level speculation) support. For this I tried to follow the steps described in http://llvm.org/docs/ExtendingLLVM dot html#instruction. But I could not find any llvm/lib/AsmParser/Lexer.l and llvm/lib/AsmParser/llvmAsmParser.y file in both the svn repository and the source code downloaded

I was reading: https://llvm.org/docs/ExtendingLLVM.html And am heeding the warnings that come with new (derived) types. I'm trying to use LLVM to model chemicals. More specifically, there are several reactive groups that exist: salts, bases, acids, etc. that adequately represent their respective values. I, for obvious reasons, want to manifest those types in LLVM so I can type check a

Hello. I come back to this thread. But I want to ask a slightly different question. Is there a way to have LLVM IR language intrinsics that are given at construction time a string that is written at assembly generation time as it is? (so, basically having placeholders of strings in LLVM that remain untouched until the end, including code generation time.) More exactly, I would

Hi, I'm trying to follow the instructions on how to add a new bitcode instruction: http://llvm.org/docs/ExtendingLLVM.html This is my first foray into the guts of LLVM and I'm not sure I'm doing things the right way. I came up with a patch that adds a NOP (no operation) that will work with llvm-as, llvm-dis, and lli. It would be nice if one of the experts could take a look and give

​Hi. I want to change order of code basic blocks in memory. I visited " http://llvm.org/docs/ExtendingLLVM.html" page and it advised me to ask it before any effort. What parts of LLVM help me and how? I am a newbie on LLVM. Thanks. -------------- next part -------------- An HTML attachment was scrubbed... URL:

I'm not sure i would try to port instead of just rewrite. The whole goal of MemorySSA is to enable us to write memory optimizations in non-N^2 ways. If

Hi, The document for "Adding a new SelectionDAG node" ( @ http://llvm.org/releases/2.9/docs/ExtendingLLVM.html#sdnode ) says, "1. include/llvm/CodeGen/SelectionDAGNodes.h: Add an enum value for the new SelectionDAG node." Where exactly shall one add the info for new SelectionDAG ? I dont see enums for other SDnodes too. Please help. Regards, Ankur

Hello again, I really need to know how to make llvm understand the annotate in C++ code or to write a new Intrinsic by myself. I tried to add a new Intrinsic corresponding to the ExtendingLLVM doc instructions, but it is too opaque and I faild. Please, advise me if you can. Sincerely, Hripsime.

> Here is my problem: > what does instrinsic / intrinsic function really means? You probably need to look at http://llvm.org/docs/ExtendingLLVM.html. Simply put, when you want to extend LLVM IR, say adding a new LLVM instruction, you have better try to add a intrinsic function [1] which has the same effect as the instruction you want to add. I don't think they are the same

Have you looked at these? https://llvm.org/docs/LangRef.html https://llvm.org/docs/ExtendingLLVM.html On Tue, Mar 26, 2019 at 9:06 AM div code via llvm-dev < llvm-dev at lists.llvm.org> wrote: > Of course, in this sense they are not platform-dependent.

Hello . I would like to add new custom data type to llvm C parser, I use LLVM/Clang version 3.1. Adding new type instructions from llvm.org site are out of date (http://llvm.org/docs/ExtendingLLVM.html#type). Could you please provide me with guidance? Thanks in advance, Edvard  -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, I want to implement a new intrinsic in llvm that will denote a parallel section within a function. I followed the documentation for extending llvm (http://llvm.org/docs/ExtendingLLVM.html) but there is something about the working mechanism that is not clear for me. 1. Why do we have to add support for the C backend? Is this only necessary to transform the llvm assembly (bytecode) into C code

Dear folks, If I want to setup a mapping between an LLVM instruction and the x86 assembly instructions it generates, is this possible? Or, an equavalent question is, when LLVM is emitting assebmly instructions, will it transform a set of LLVM instructions to a set of assembly instructions, or transform each LLVM instruction to assembly instructions independently? -- Regards, Heming Cui

Hi Shahid. Do you mind providing a concrete example of X86 code where an intrinsic was added (preferrable with filenames and line numbers)? I'm having difficulty tracking down the steps you provided. Any help is appreciated. On Mon, Apr 4, 2016 at 9:02 PM, Shahid, Asghar-ahmad < Asghar-ahmad.Shahid at amd.com> wrote: > Hi Rail, > > > > We had done this for generation

Hi Dan, Yes, they could be represented with insertelement and extractelement, but I don't think they actually generate optimal code using movq2dq and such. Else both bugs 2584 and 2585 would be fixed. Anyway, I'm actually already encouraged to get involved myself. I'm quite experienced with MMX and SSE but I'm still trying to learn more about how LLVM does instruction selection
