Hi Koen, The process to build llvm-gcc as a crosscompiler is basically the same as build a normal gcc as crosscompiler. The differences: you need a LLVM installed (compiled for the host). You must configure llvm-gcc with --enable-llvm. Problems: - Today LLVM supports ARM/EABI, but llvm-gcc don't. You must apply the patch:

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, After hearing Chris' talk at bossaconference I wanted to see if I could use LLVM (and/or llvm-gcc) as a crosscompiler for ARM. The documentation beautifully outlines how to build it for your host and how to crosscompile it, but not how to build it as a cross-compiler. So my question is: How should I build llvm and llvm-gcc4 to have it

It has some bug fixes that are important to ARM EABI and the patch should apply cleanly. Lauro

Hello > grep llvm configure* doesn't return anything in trunk/, did I > checkout[1] the wrong svn? No. It's ok :) It's just complicated nature of gcc's build system. In fact, try "grep llvm gcc/configure" :) -- With best regards, Anton Korobeynikov. Faculty of Mathematics & Mechanics, Saint Petersburg State University.

You haven't specified any ARM specific stuff during llvm-gcc conffigure (cpu type, fpu type, floating point abi, etc). This means that default will be used. LLVM defaults to

Hello, Pazzo > I had a look to llvm (2.6) configure options but I couldn't find any > way to specify cpu type, fpu ecc.. These are not llvm configure options, but gcc's one.

Dear ML, I'm trying to understand how to build a llvm (2.6) cross compiler for arm-elf target using the gcc frontend with newlib. Could you please indicate, if possible steps I should follow? I try to configure and build llvm with ../llvm-2.6/configure --prefix=/usr/local/cross-llvm-gcc-arm-elf-4.2-2.6 --enable-optimized --disable-threads --enable-targets=cbe,cpp,arm and LLVM-GCC frontend

Dear ML, Anton, Thank you for your answer and your help. I had a look at ARM.td of LLVM 2.6 (in lib/Target/ARM..) where I found following definitions: // V4T Processors. def : ProcNoItin<"arm7tdmi", [ArchV4T]>; def : ProcNoItin<"arm7tdmi-s", [ArchV4T]>; def : ProcNoItin<"arm710t", [ArchV4T]>; def :

i am getting this compilation error: gcc -c -g -O2 -DIN_GCC -DCROSS_DIRECTORY_STRUCTURE -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -pedantic -Wno-long-long -Wno-variadic-macros -Wno-overlength-strings -Wold-style-definition -Wmissing-format-attribute -DHAVE_CONFIG_H -I. -I. -I../../llvm-gcc-4.2-2.7.source/gcc -I../../llvm-gcc-4.2-2.7.source/gcc/.

Dear Anton, Thank you again for your help! I tried with the following options (adding --with-cpu=arm7tdmi and using binutils from cvs snapshot): ../llvm-gcc4.2-2.6.source/configure --prefix=/usr/local/cross-llvm-gcc-arm-elf-4.2-2.6 --program-prefix=llvm- --enable-llvm=/Users/dummy/Develop/llvm/llvm-build --enable-languages=c,c++ --host=i686-apple-darwin9 --build=i686-apple-darwin9

Hi,    I use the crosstool build script to build a crosscompiler for ARM. I get the following error when compilng "helloworld" program:   llvm-gcc hello.c -o hello   as: unrecognized option `-meabi=4'   I know that the reason is not to get proper cross assembler. It tries to use the native assembler but I am unable to fix the problem. I use llvm-gcc -### hello.c -o hello and see

Dear Anton, Thanks for your help! I had a look to llvm (2.6) configure options but I couldn't find any way to specify cpu type, fpu ecc..Could you please give me any indication and/or example?

I'm looking for an antivirus program for a Samba fileserver (PDC). Is ClamAV good enough? It seems to be mainly used for mail servers... Any other suggestion, free or non-free? I tried F-secure antivirus for linux servers but it keeps giving problems. All clients use F-secure which i centrally manage from another linux server which is pretty good imo. I read other people suggesting to use

This testscript creates reflinks to files on different subvolumes, overwrites the original files and reflinks, and moves reflinked files between subvolumes. Originally submitted as testcase 302, changes are made based on comments from Eric: http://oss.sgi.com/archives/xfs/2013-03/msg00231.html Two new common/rc functions used in this script (_require_cp_reflink and _verify_reflink) have been

Hi list, I'm looking for a function or a combination of functions to do panel plotting of mixed graph types with the same x axis. I would like to construct a panel with 3 stacked windows with on top a histogram, below that 2 cdf plots. They all have the same x axis value but different y axis values. Is it possible to construct something like that? I've looked into the lattice package

You need to configure with --enable-llvm. (It would still be nice if V1DI_pointer_node was defined; I'll take a look at that.)
