Hi,
I am on CentOS 7 with kernel package 3.10.0-862.2.3.el7.x86_64.
I was looking at the scheduling info of my application by cat
/proc/[pid]/sched:
---
se.exec_start: 78998944.120048
se.vruntime
What I mean is will it nowadays compile the kernel with 4.19 or do you need
to manually hack the inline asm?

Well I found and old post by John Criswell describing how he did his
dissertation project SVA. He didn't use LTO but llvm-link. So I figure I
would try to do it that way and see if this works since I am not sure how
good the current support for LTO is. Will clang generally work if an
external assem

Then add those options to the p
The problem is I have to do something special with the clang options. I
have to add an interprocedural link time optimization pass spitting out
bitcode files and tying them together using llvm-link.

Hi,
I am having exploring how much work it would be to do whole kernel
optimization using clang on the current kernel. My understanding is the
kernel uses a recursive make file system. I am curious if there are any
easy ways to get the kernel to build llvm bit code for all files without
going thro
