[LLVMdev] Limit loop vectorizer to SSE
Nadav,
I believe aligned accesses to unaligned pointers is precisely the issue.
Consider the function `add_u8S` before[1] and after[2] the loop vectorizer
pass. There is no alignment assumption associated with %kernel_data prior
to vectorization. I can't tell if it's the loop vectorizer or the codegen
at fault, but the alignment assumption seems to sneak in somewhere.
v/r,
Josh

Adding memdisk or similar when booting linux
Hi
Thanx guys for the help on understanding howto read dmi info!
I now have a custom boot menu for install of different linux versions based if they have been installed before (reinstall is ok for users, first install is not), and installquirks like if we detect odd hardware, we add install options to redhat installer so it can install anyhow (for instance hp dc7800 who needs pci=nommconf as

[PATCH 00/12] elflink shrinkage
From: Matt Fleming <matt.fleming at linux.intel.com>
This is a series of patches that,
* shrink the core by moving things into an ldlinux ELF module
* begin wiring up some of the C versions of various functions
The core now only contains essential code and loads the ldlinux module
to do everything else, like providing a command line interface and
loading kernels.
The config file parsing
