similar to: [LLVMdev] llvm-gcc as Alpha cross compiler

Thanks Andrew. I would like to clarify what I tried to do. I want to use llvm-gcc on x86 linux to compile C programs into Alpha binary.

llvm-gcc doesn't not compile *on* alpha (128bit fp and int issues). I haven't tried it as a cross compiler.

Thank you, I did try that and got the following error: checking for library containing strerror... configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES. make[1]: *** [configure-target-libiberty] Error 1 make[1]: Leaving directory `/home/ghoang/llvm-test/llvm-gcc-2.8-build' make: *** [all] Error 2 I also tried adding --disable-libiberty but make would fail even earlier

Hi, I am trying to build the front end llvm-gcc 2.8 on 32-bit Ubuntu 10.04, using gcc 4.2.4. I was able to configure and build llvm-2.8 in the directory llvm-2.8-build. Here is the command I used to configure llvm-gcc build: ../llvm-gcc-4.2-2.8.source/configure --enable-checking --disable-bootstrap --disable-multilib --enable-llvm=/home/ghoang/llvm-test/llvm-2.8-build/ --enable-languages=c

try --disable-libmudflap when you config llvm-gcc FE:) On Mon, Jan 16, 2012 at 9:44 AM, Giang Hoang <ghoang84 at gmail.com> wrote: > Hi, > > I am trying to build the front end llvm-gcc 2.8 on 32-bit Ubuntu 10.04, > using gcc 4.2.4.  I was able to configure and build llvm-2.8 in the > directory llvm-2.8-build.  Here is the command I used to configure llvm-gcc > build: >

Hi, For my work, I want to use LLVM to compile SPEC 2k for Alpha. Since Alpha support has been dropped, I tried using version 2.8, but it is quite buggy, probably because the Alpha backend has not been maintained. I was wondering if there is an earlier version where the Alpha backend is stable enough to compile SPEC 2k? For my purpose, I do not need the most advanced optimizations, so an

Hi Giang, Given that the community deprecated the Alpha backend, I'm doubtful anyone would be able to point you in the right direction. Have you iteratively tried the difference versions of LLVM (i.e., 2.9, 2.8, 2.7 on down the line)?

Hi, I encountered an error while trying to use the indirectbr instruction with Alpha backend (current build). Here's part of the code sequence that I tried to compile: bb1: %1 = load i32* %i, align 4 %2 = add nsw i32 %1, 1 store i32 %2, i32* %i, align 4 indirectbr i8* blockaddress(@main, %bb1), [ label %bb1 ] br label %return This compiles correctly when I use the X86 or PPC

Hi, For my research, I need to reshape the current ARM backend to support armv2a. Zero-extend half word load (ldrh) is not supported by armv2a, so I need to make the code generation to not generate ldrh instructions. I want to replace all those instances with a 32-bit load (ldr) and then and the result with 0xffff to mask out the upper bits. These are the modifications that I have made to

Hi, I want to add an extra instruction to the Alpha ISA. This is not a new operation; it is just an addition with a lower latency, let's call it fast-add. Could you give me advice on what's an easy and clean approach to this? I am thinking of adding an extra instruction to the LLVM IR to represent this fast-add operation (I want to make the decision of using either the normal addition

I've committed my scripts that simplify building Linux/x86 -> Linux/ARM crosstool. There are 2 parts to using this: * llvm/utils/crosstool/create-snapshots.sh creates tarballs for LLVM and LLVM-GCC from HEAD SVN or a specific revision of your choice * llvm/utils/crosstool/ARM/build-install-linux.sh builds and installs a Linux/x86 -> Linux/ARM crosstool using the snapshots generated

Thanks Misha, However, I could not find the crosstool. Could you please check the name of the script?

Hi      I am using LLVM and LLVM-GCC from SVN (version number: 122880). And I am using arm-2009q1-176-arm-none-linux-gnueabi-i686-mingw32.tar.bz2 or arm-2007q3-51-arm-none-linux-gnueabi-i686-pc-linux-gnu.tar.bz2. I tried the automated scripts (create-snapshots.sh and build-install-linux.sh) that are in the LLVM repository for building crosstoll for ARM

Hi all, Since the 3.1 testing day is coming and be a ARM tester, I would like to make sure everything is O.K. so that we don't waste the precious time. As discussed on the ML before, I plan to cross compile LLVM/Clang first, then run regression test and test suite on the pandaboards. Could someone help me check to see if I miss something? Thanks! Here is the pandaboard configuration,

Can someone with llvm-gcc/ARM expertise (Dale?) please review Sandeep's patch? The patch works for me in building an LLVM-based cross-compiler from x86_64/Linux to ARM/Linux. I have been able to build without the patch to the asm file, but several people have reported needing the asm patch on http://llvm.org/PR2545 .

Attached is the patch I've been building arm-eabi with, which might help with linux-gnueabi. I disable multilib to get around several bugs with thumb. I build cross binutils first, then llvm, then llvm-gcc with newlib merged in. The following bugs need to be addressed for these non-Darwin ARM targets: 1388 2313 2545 2985 deep On Fri, Mar 13, 2009 at 12:30 AM, Misha Brukman <brukman at
