It's been implemented piece by piece on an as-needed basis. At this point most of the things people actually use should work. llvm-gcc has seen the Linux kernel, so most usages in there ought to work. The symptoms here

Thanks for the help. I've a couple of questions though: How does LLVM deal with inline assembly? I'm trying to compile kernel and I get this error probably because LLVM is not able to handle inline assembly. I'm using LLVM-2.3 code snippet from "arch/x86_64/kernel/asm-offsets.c" .... #define DEFINE(sym, val) \ asm volatile("\n->" #sym " %0 "

Thanks. I actually checked the IR code generated, it seems inline assembly is being handled correctly. The preprocessing is also being done correctly. Here is the asm-offsets.i file snippet.. ... builtin_offsetof(struct crypto_tfm,__crt_ctx))); asm volatile("\n->" : : ); asm volatile("\n->" "__NR_syscall_max" " %0 " "sizeof(syscalls) - 1"

We seemed to have it a stumbling block when building with the above (supported) versions. Our process... 1. Start with stock rhel5 2.6.18-8.1.14 source tree 2. Configure InfiniBand support out of the the kernel (we will build OFED separately). 3. Apply the 1.6.4.2 kernel patches to the kernel source. 4. Build the kernel. 5. Build OFED 1.2 against the patched kernel 6. Build Lustre using

Hello, I am trying to compile RHEL-6 kernel srpm on Fedora 14 and run into the following problem. From what I read -Werror flag causes warnings to be treated as errors - but I don't see that flag on in the following. Any ideas? gcc -Wp,-MD,arch/x86/kernel/acpi/realmode/.wakemain.o.d -nostdinc -isystem /usr/lib/gcc/i686-redhat-linux/4.5.1/include -nostdinc -isystem

Hi, I'm trying to compile linux-2.6.23.16 with llvm-2.3. Is it at all possible? I get "Not an ELF" error. I pass "-emit-llvm" option to spit LLVM IR, which can be JITed at runtime $ make CROSS_COMPILE=llvm- CFLAGS="-O2 -emit-llvm" Error: not ELF make[2]: *** [scripts/mod/elfconfig.h] Error 1 make[1]: *** [scripts/mod] Error 2 make: *** [scripts] Error 2 using

Hello All, As part of my clang/LLVM experiments and explorations with different clang-built kernel versions, I have tried to bring up other Linux/Ubuntu applications with their kernel modules also being clang-built. One such case has been with VMware Player 14.1.1. I am sharing this report for interested people that highlights my research and success in overcoming and solving the challenges in

Hi Devang, Is there any particular reason as to why debug info support for tls hasn't been implemented. Is the feature in pipeline ? How hard is it to implement ?

Yes, but it requires significant hacking, and the result for 2.6 is a mostly bitcode kernel with a few userspace shared libraries linked in as objcode (yes, the kernel builds .so files and includes them

Does anyone have experience to compile Linux kernel in LLVM-2.6? I am working on a C/C++ race detection framework and want to test in large applications. But I do have a lot of errors while compiling Linux kernel 2.6.3 using LLVM-2.6. Actually, I only need to get the .bc bitcode file. Anyboy does similar work before? Which Linux kernel version is used and any skills? Thanks. Lei /****** * Lei

Thank you all. It looks like -mno-red-zone flag is already in master branch since commit 7d70885d, but it seems it is applied to all EFI builds. IIUC, the problem only affects efi64 builds. So here's the modification of my patch to only apply -mno-red-zone flag to efi64 target. The patch is against master. I verified that it builds correctly in master. Please feel free to accept or reject

Hi all, I encountered an error while compiling Linux kernel 5.3 to IR. My LLVM version is 9.0.0 release. This error said "invalid operand for inline asm constraint 'i'" in arch/x86/include/asm/jump_table.h. The source code is static __always_inline bool arch_static_branch(struct static_key *key, bool branch) { asm_volatile_goto("1:" ".byte "

Dear R users I'm new in R management and maybe It's a silly question. I'm working with GLM to obtain predictive models. I have some problesm with the prediction instruction: > DatosTotal <- read.csv("Var_perdizcsv.csv", sep =";") > edvariable <- edit(DatosTotal) > pre <- predict(rlfinal, DatosTotal, type = 'probs') Erro en

I think I see what's going on, and I agree it looks like a bug. It was too much to hope that later passes weren't going to mess with the PUSH instruction. :( While I was trying to reproduce your problem, I think I found another one that looks like this: $ clang -S -O2 -m32 -mregparm=3 -mretpoline spill_across_rp.cpp -o - | grep _retpoline_push -B2 ... movl %eax, 8(%esp)

I am working on a script that takes numeric performance indicators and runs them against a series of regressors (dummy regressors, yes\no stuff via 0 and 1, e.g. Was is Christmas this week 0=no, 1=yes). The script is as follows (Written as a function): -- Begin Script -- doEnv <- function(HOUR,ENVNAME,REPORTNAME) { library(RODBC) library(forecast) library("geneplotter")
