similar to: [LLVMdev] Linux Kernel Compile for Sparc v8 Arch

Does anyone succeed at compiling Linux kernel for Sparc v8 architecture? I am currently trying to expand the regime of LLVM to Sparc kernel codes. The following is the initial error messages. Any comment is welcomed. #1. Inline Assembly Code: register struct thread_info *current_thread_info_reg asm("g6"); Error Message: include/asm/thread_info.h:77: error:

Hi, The source attached at the bottom is a testcase which causes a back-end error in LLVM 2.4. These types of assembly routines are mainly used in OS kernels. I checked that GCC 4.3 works for this routine. The error messsage is ... Couldn't allocate output reg for constraint 'A'! I just need help or comments so that I could analyze and fix this bug. My

Hi Armin! I have problems on debian sarge with standard 2.6.8-2-386 kernel. I've installed the packages: kernel-headers-2.6.8-2 kernel-headers-2.6.8-2-386 kernel-image-2.6.8-2-386 kernel-kbuild-2.6-3 kernel-source-2.6.8 Then I unpacked the kernel sources into /usr/src/kernel-source-2.6.8 and made a symlink from /usr/src/linux --> kernel-source-2.6.8 Then I entered

Hi, I have couple of questions that those who design unconventional passes would be interested in. 1. How to move a virtual register data to another new virtual register? It seems like that there is no LLVM instruction similar to mov machine instruction. Arithmetic or logical operators could be used for integer variables but what about pointer variables? 2. What is

Hi, This is a simple question about building ARM cross-compiler. What is the building procedure using LLVM 2.4 and GCC front-end 4.2? I used these commands for LLVM, and it is okay. $ ../configure --prefix=/usr/local -target=arm $ make ENABLE_OPTIMIZED=0 $ make ENABLE_OPTIMIZED=0 install Then these commands were used for GCC front-end but this got couple of errors. $ ../configure

Greetings, I''m unable to build current (Sun Feb 26 18:14:23 UTC 2006) linux-2.6-xen.hg on Debian sarge AMD64 host.

Hi I am writing a freestanding statically linked x86_64 kernel. And now I want to load and use thread-local storage. As I have a freestanding binary I can't use libc/Linux kernel thread-local mechanism and need to implement initialization code by myself. I am trying to find a clear explanation of what is the memory layout for x86 TLS but can't find anything useful. Maybe LLVM developers

Hello, I am trying to run xen-3.0 in some of my dell servers. I have tried the binary distribution of xen, but it doesn''t boot in my test system (a dell poweredge 750) because a module driver problem (I get an error message during booting saying it doesn''t load a NFS root filesystem). So I am trying to compile a custom kernel. So I have downloaded linux source 2.6.12. I am

[ Expand, correct and clarify comments; minor code change. ] Most of the time we can simply use the iret instruction to exit the kernel, rather than having to use the iret hypercall - the only exception is if we're returning into vm86 mode, or from delivering an NMI (which we don't support yet). When running native, iret has the behaviour of testing for a pending interrupt atomically
