similar to: [LLVMdev] How to make a cross compiler for xilinx microblaze

conmfigure does not accept mblaze nor mblaze-elf as target. checking target system type... Invalid configuration `mblaze': machine `mblaze' not recognized configure: error: /bin/bash ../../spare/llvm/autoconf/config.sub mblaze failed However with microblaze it proceeds fine. But when i try to use clang i get: clang: error: 'microblaze-unknown-none': unable to pass LLVM bit-code

Hi Fivos, LLVM refers to the target as "mblaze" for -target. -Jim On Jun 26, 2012, at 8:42 AM, Fivos <fivosz at gmail.com> wrote: > Hello, > > i am trying to create a LLVM stack to cross compile c code targeting the > xilinx microblaze. > > I built LLVM configured with target=microblaze however cland doesn't > like it. When i try to emit llvm code

I have been working on a LLVM backend for the MicroBlaze soft-processor: http://www.xilinx.com/tools/microblaze.htm http://en.wikipedia.org/wiki/MicroBlaze Attached is the initial MicroBlaze patch. It does the following: 1. Adds mblaze as a target in configure and configure.ac 2. Adds mblaze specific intrinsics in include/llvm/IntrinsicsMBlaze.td and include/llvm/Intrinsics.td 3. Adds mblaze

Still the same. Is there any chance that the placement of my directories are causing this? Also the exact command that fails is /home1/public/zakkak/java/vmkit/Release+Asserts/bin/vmjc -std-compile-opts -load=/home1/public/zakkak/java/vmkit/Release+Asserts/lib/MMTKRuntime.so -load=/home1/public/zakkak/java/vmkit/Release+Asserts/lib/MMTKMagic.so -LowerMagic

Hi, My machine is running Ubuntu server 64-bit And the revision from the trunk is 158095 for llvm, clang and vmkit llvm configuration ../../llvm/configure --enable-doxygen --enable-optimized --disable-jit vmkit configuration ../../llvm/vmkit/configure --with-llvmsrc=/home1/public/zakkak/llvm/ --with-llvmobj=/home1/public/zakkak/java/llvm/

Hi Nicolas, I thought MMTk is written in java and it is compiled by javac. retried a clean build with JIT enabled llvm configuration ../../llvm/configure --enable-doxygen --enable-optimized --enable-jit vmkit configuration ../../llvm/vmkit/configure --with-llvmsrc=/home1/public/zakkak/llvm/ --with-llvmobj=/home1/public/zakkak/java/llvm/

Hi Nicolas, it looks like there are missing things $ more lib/j3/LLVMRuntime/LLVMRuntime.inc // Generated by llvm2cpp - DO NOT MODIFY! Module* makeLLVMModuleContents(Module *mod) { mod->setModuleIdentifier("<stdin>"); // Type Definitions // Function Declarations // Global Variable Declarations // Constant Definitions // Global Variable Definitions // Function

Hi Fivos, I cannot reproduce on my machine (ubuntu 64bit, clang/llvm/vmkit on svn trunk). What's your configuration?

Hi Fovios, Do you have a ./lib/j3/LLVMRuntime/LLVMRuntime.inc file being generated? What does it contain? Nicolas On Thu, Jun 7, 2012 at 5:47 PM, Foivos S.

Hi Nicolas, I finally found the root of the problem. Build was unable to locate llvm-build because it was looking for it in path/to/vmkit_src/utils/llvm-build while it was located in path/to/llvm_src/utils/llvm-build Actually llvm-build's path is defined by the path/to/llvm_src/Makefile.rules and looks like this LLVMBuildTool := $(PROJ_SRC_ROOT)/utils/llvm-build/llvm-build however in

VMKit needs it to compile MMTk.

Hello, after completing the build i get ...

Hi, I just saw this thread. I work on llvm at Xilinx but I do not work on microblaze. I will check to see if there is any interest here at Xilinx to contribute resources to the maintenance of this backend.

I think you should wait until it becomes a problem. Xilink is actively hiring for LLVM people so maybe it will get some use again soon. I get at least one email a day from their head hunters. http://en.wikipedia.org/wiki/MicroBlaze On 02/05/2013 01:02 PM, Chandler Carruth wrote: > > > > On Tue, Feb 5, 2013 at 12:52 PM, Chandler Carruth <chandlerc at gmail.com >

folks hi, something i just wanted to double-check. is it possible to use, with LLVM, entirely free software tools to build and upload to a xilinx microblaze FPGA target? i take some c code, put it through llvm-fpga, aaand... then what? is there any documentation about this stuff, anywhere? tia, l.

The MBlaze backend seems to be essentially unmaintained since 2011. The maintainer (Wesley Peck who is BCC'ed) seems to have vanished, and in fact all emails to him are bouncing. I propose to remove the MBlaze backend on Friday if none step forward as a maintainer. Currently, folks are having to keep it up to date when changing shared parts of the backend with no help. -Chandler

The Sparc, Microblaze, and Mips code generators implement branch delay slots. They all seem to exhibit the same bug, which is not surprising since the code is very similar. If I compile code with this snippit: while (n--) *s++ = (char) c; I get this (for the Microblaze): swi r19, r1, 0 add r3, r0, r0 cmp r3, r3, r7 beqid r3,
