Hello, i need to fold constants, i found that a function ConstantFoldConstantExpression could be used, however I am not able to make it fold anything. Could you please give me some advice, what I am doing wrong? My code looks something like this: //data layout is obtained from clang-generated code for triple arm-none-linux-gnueabi with added v32:32:32 const char* const TARGET_DATA_LAYOUT =

I forgot to mention, that I use LLVM release 2.8, I did not try it with the latest revision, but I expect that I am rather doing something wrong than using non-implemented functions.

Adam, I just fixed this issue a few days ago. A version from the trunk should work for you.

Hello everyone, we are planning to implement a stronger alias analysis for backend, because e.g. for VLIW architectures, this is our main performance limitation. I would have 2 questions regarding this. I know that backend processes one function at a time, is it somehow possible to do there a whole program analysis, or could you give me some guidelines? Which alias analysis algorithm

Hi everyone, I am trying to write a pass, that finds some instructions and replaces them with my intrinsics, but I am having problem understanding, how this should be done. Let's say I have this instruction: %tmp14 = load i32* getelementptr ([32 x i32]* @gpregs, i32 0, i64 28) and i need to read the load's operands and replace it by let's say: %tmp14 = call i32

Hello gyus, I am working on a project, where we are trying to create a development environment for new ASIP processor design. Part of this project is a compiler generator, where we would like to generate C compiler from some instruction description. To keep it short, let's say, that in each instruction's semantics is described by some C code. What I would like to do is to compile this

Dear all, I would have a proposal for adding a project to the page http://llvm.org/ProjectsWithLLVM/. We successfully use LLVM as a base for a retargetable compiler and below is some information on the project. If you would have any comments, questions or if we should improve the text below, please let me know. --- Codasip Studio By Codasip Ltd. (link https://www.codasip.com/) Codasip

Hello! I was trying to optimize our automatically generated backend for Open RISC and for this purpose I went through the gcc torture testsuite. There are many programs that are better optimized by LLVM, but some are much better optimized by gcc 4.9. The main limitations were is loop unrolling and structures handling. Differences can be best seen e.g. when compiling for an

Hallo! While compiling Icecast (after successfully installing libshout, ogg, vorbis-tools, and libao on a Red Hat 8.0 system) I get the following error which causes the compilation to abort: --- quote: [...] make[2]: Entering directory `/usr/local/programs/icecast/src' source='yp.c' object='yp.o' libtool=no \ depfile='.deps/yp.Po' tmpdepfile='.deps/yp.TPo' \

Hello, I need to allow for some people to execute ssh with one shared private key for remote executing command on various machines. However, it is not possible to set group permissions for private keys and it is possible to have just one private key file for one user. Please, is it possible to add patches into openssh development tree like these, so that standard behavior of ssh is not changed,

Hi, I am newbie for LLVM. I need some help, I want to disassemble ARM binaries and perform some operation on LLVM IR and again back to generate ARM binary from modified ARM LLVM IR. How I can proceed for the same. Any tool or document will be highly appreciated. Thanks and Regards, Deep -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello How do I subscribe to samba-docs mailing list? The list is listed at http://samba.kn.vutbr.cz/samba/archives.html however it is not listed on the subscription page at http://lists.samba.org/mailman/ judging by grepping 'samba-docs' in the page and finding nothing. Cl<

Hello, I would like to ask, whether do the functions code in the compiler-rt library are written in the way that they can be used also for 16-bit architectures, or it was intended for 32-bits only. I looked at the code and it seemed quite portable, but are there any issues I should know when trying it for 16-bit architectures? Thank you Adam

LLVM version: 2.6 Query context: Automatic generator of LLVM backends. Query: What are canonical rules for initial DAG (generated by LLVM)? Are there any at all? Example: Commutative operations. Are operations like X = 1 + REG automatically transformed into X = REG + 1 ? Because of the nature of our project, we need exact information. Thank you very much. JH
