similar to: [LLVMdev] Adding Intrinsics for custom processor (frotend problem)

As mentioned in an earlier mail, I am working on an LLVM backend for a custom processor based on MIPS. My problem is how to extend LLVM to support some esoteric/non-standard feature of the underlying hardware. I saw in the "Extending LLVM" document, that the easiest / most common way to do this was using an intrinsic function, and examples of the technique abound (all SSE for

Personally I would just modify the frontend - it's not that hard once you know where to look . In this case all you need to do is add the declaration of your builtin to the TARGET_INIT_BUILTINS target hook (see the gcc internals manual) defined in the gcc/config directory corresponding to your target. If the name the the declaration matches the name used with GCCBuiltin in the intrinsics

Hi. My name is Gil Dogon and I am working in MobileEye using LLVM in order to generate code for a proprietary processor. Our processor architecture is very similar to MIPS, so I started to work using the "experimental" MIPS back end. Anyway, my question is rather simple but somehow I did not find a quick answer to it in the documentation. What I want to know, is how can the

Using GCC 4.9.2, decoding the opus test vector set 10 times. All tests pass. I will do longer tests later with a larger test set, but it looks good so far. I am having a lot of trouble with the Ne10 detection. Using the precompiled Ne10 binaries at http://people.linaro.org/~viswanath.puttagunta/opus/NE10_root/ Both NE10 and Ne10 capitalizations seem to be in use. Also, where should the NE10

Hi! Apparently there are no precompiled binaries for llvm-gcc 4.0 for Linux. I've tried downloading the sources and building according to http://llvm.org/docs/CFEBuildInstrs.html (except I'm not an elite gcc hacker). I tried following the guidelines and got what looks like a gcc for x86 with no traces of LLVM. I tried passing --enable-llvm with various llvm root pathnames and got ICEs.

Dear all, Since version R-2.12.0, I've got problems building an add-on package for R ("imglib" here) for 32-bit Windows. The following command is called: C:\Program Files\R\R-2.12.0\bin\i386\Rcmd build --binary imglib And here is an error I am getting in the end of processing: ** testing if installed package can be loaded Error : package 'imglib' is not installed for

Hi, I got lots of "undefined reference" when building vmkit. Anyone can help to give a solution? I download vmkit with "svn co http://llvm.org/svn/llvm-project/vmkit/trunk/", followed the instructions of "http://llvm.org/svn/llvm-project/vmkit/trunk/README.TXT", and built vmkit on ubuntu 13.10 x64 with sunjava 1.6.0_45 + llvm 3.3 + classpath 0.99 + gcc 4.8.1.

Hi, I''ve just updated my app to the final 3.1 release and deployed it to the staging server after running tests but there is a problem with the precompiled assets. The precompiled assets are all in the public directory, like they were before, Capistrano doesn''t throw any error and running `rake assets:precompile` in the current directory work as expected. But the asset

I'll test on Darwin/PPC, precompiled llvmgcc, objdir == srcdir.

hi all, i surely overlooked something. but i am currently trying to do some benchmarking stuff with llvm. in my thesis i was using llvm-1.5 (i did some extension work, which i would have to frontport now). But unfortunately 1.5 is for some benchmarks unstable (at least on my box) such that llc sigsegvs sometimes, etc. So I wanted to give 1.9 a go and build that on the my intel mac book. I did

Hi , I have an issue during LTO phase of llvm compiler which is as follows, File t3.c --------- #include <stdio.h> #include <stdlib.h> // A linked list node struct Node { int data; struct Node* next; struct Node* prev; }; struct Node* head; /* Given a reference (pointer to pointer) to the head of a list and an int, inserts a new node on the front of the list. */

Hello, I do not know whether this idea would be considered useful or not. Or easy to implement. But it is the case that on certain Linux distributions there are OS packages with precompiled R packages. However, install.packages (and related functions) download the source ones. Would it be possible to add an extra "repository" (or option) on install.packages that would direct R to

I tried to use lsode with precompiled C code instead of an R function defining the derivatives. No problem so far. However, now I need to implement an ODE that contains spline functions, i.e. the derivatives at given time points depend on the value of a spline function at this time point. What is an efficient way to implement this in precompiled C code? -- Daniel Kaschek <daniel.kaschek at

I haven't seen anyone claim x86 linux objdir == srcdir, so I'll test it out. Missed the 18th,but I'll try to have it done asap. On Apr 18, 2006, at 2:51 PM, Robert L.

Hi Johannes, Thank you for your quick feddback. As I am using linux os build with buildroot on my raspberry pi I can't use package manager such as apt-get to install R. What I need to do is to get the precompiled R for arm arch and then when I build my linux image using buildroot I include the R precompiled package to my rootfs. Could you please send me a link where I can download

I'm having a problem with MCJIT (in LLVM 3.3 and 3.4), in which it's not resolving symbol mangling in a precompiled bitcode in the same way as old JIT. It's possible that it's just my misunderstanding. Maybe somebody can spot my problem, or identify it as an MCJIT bug. Here's my situation, in a nutshell: * I am assembling IR and JITing in my app. The IR may potentially make

Hello Thomas, I use the following configure command to link against Ne10 Eg: configure --host=arm-linux-gnueabihf --enable-intrinsics --with-NE10-libraries=${BUILD_NE10_LIB} --with-NE10-includes=${BUILD_NE10_INC}" So, in my normal testing, I explicitly specify where the NE10 header files are installed and where the NE10 libraries are installed. Looking back at configure.ac

Dear r-help- >From reading the CRAN web page, it appears that you should not submit precompiled binary versions of your package, but rather that these are built for you by someone working with CRAN. I submitted my package using R CMD build but without the binary flag on. I'd like to have a binary version available for Windows users. Should I submit a precompiled binary version as well?

Hi all, I want to install wgrib2 on my windows 7 laptop. It appears that a precompiled version exists and works for many. I managed to download a precompiled version and placed it in a directory and added this directory to the PATH. However, when execute R-command, I get the error suggesting that wgrib2 is not recognized as either internal or external command. Any suggestions? Thanks
