Hi, I'm interested in developing a 64-bit operating system to run inside a version of BOCHS compiled with x86-64 support enabled (bochs-2.2.6-x86-64.exe) that I found on the web. Can I use LLVM as a GCC replacement for OS development? I need to generate 64-bit x86-64 assembly language output which I can then assemble with the normal 'as' and link via 'ld' commands. How do

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:

Hello, Koen. > So my question is: How should I build llvm and llvm-gcc4 to have it cross-compile from x86 > to ARM/EABI? Well, just supply appropriate --host/--target options to configure. I haven't tried ARM, but this definitely works for crosscompiling from linux to mingw32. Please also note, that you'll need native (=arm) tools (binutils, libcheaders, etc) during gcc build

I'm looking forward to your patches and bug reports.

Currently I'm working on bootstrapping llvm-gcc4 on mingw32 platform. There are some serious miscompartibilities preventing build. I'll let know the results. Anyway, it's common knowledge, that msys itself have

Hello, Everyone. Today I've finished digging into llvm-gcc4 in order to build in under mingw32. The most trickiest was to make libstdc++ build, since its configure & makefiles are not so perfect as main gcc ones. There are several problems with inline assemler (in two places at least), but both of them are easily seen. Also, there are some compiler crashes while compiling libiberty (with

-----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

Hello, Everyone. I'm currently trying to bootstrap llvm-gcc4 on mingw32 platform. Everything (except some small fixes) seems to be fine: stage1 finished successfully. I'm linking with debug variant of LLVM, since linker bug prevents release builds. Unfortunately, stage2 failes immediately with this cryptic message: $/f/tmp/llvm/gccbuild/gcc/xgcc -B/f/tmp/llvm/gccbuild/gcc/

Hello, Everyone. All blackmagic (playing with pwd, etc) in my build description has gone with patched bash (pwd builtin was just hardly disabled). It's not good, I myself prefer modifying libstdc++ configure script to use PWD_CMD environmental variable as main gcc ones. I'm working on this feature. -- With best regards, Anton mailto:asl at math.spbu.ru

Hello, Everyone. This is just brief description on building llvm-gcc4 with mingw32. It's definitely non error-free and contains many "hacks", which should be eliminated in the future. 1.
