llvm-link has no --allow-multiple-definition
Hi Eli,
I know the page, and the only mentioning about LTO or link time
optimization I found is the option
PassManagerBuilder::EP_FullLinkTimeOptimizationLast - and nobody knows
how this works (and asked about it on this list too before with no
reply), and the author who wrote that part in the llvm code at Redhat
did not reply to a question how to actually use it. And there is no
example code or

llvm-link has no --allow-multiple-definition
HI Eli,
that sounds like the -mllvm option would be a good a mention in the
WritingAnLLVMPass document ;-)
Two further questions for this and I am keeping this on the list so
other people have pointers to this if they struggle with the same thing:
1. Does this require to use lld? (I am sure it is, just to clarify, for
the very low chance that it would also work with gnu ld and the llvm

I had that initially:
auto cf = IRB.CreateICmpULT(Incr, ConstantInt::get(Int8Ty, 1));
auto carry = IRB.CreateZExt(cf, Int8Ty);
Incr = IRB.CreateAdd(Incr, carry);
it makes no difference to the generated assembly

optimisation issue in an llvm IR pass
Hello,
I have an optimisation issue in an llvm IR pass - the issue being that
unnecessary instructions are generated in the final assembly (with -O3).
I want to create the following assembly snippet:
mov dl,BYTE PTR [rsi+rdi*1]
add dl,0x1
adc dl,0x0
mov BYTE PTR [rsi+rdi*1],dl
however what is created is (variant #1):
mov dl,BYTE PTR [rsi+rdx*1]

in an IR pass: access the instruction pointer/BB address
Hi,
I looked through the documentation and source and am unable to find a way:
in an IR pass on basic blocks
for (auto &F : M)
for (auto &BB : F) {
....
}
I want to access the current address of the basic block. It does not
need to be the exact address of the BB, a few instructions down of that
BB is fine as well.
basically the same that I could do with an "leaq

resolve the name of an ifunc resolver function
Hi,
I just spent 4 hours trying to find a way to get the name of the
resolver function of a ifunc definition ... :-(
and with all that time I didnt event get far:
for (GlobalIFunc &IF : M.ifuncs()) {
StringRef ifunc_name = IF.getName();
Constant *r = IF.getResolver();
But how do I get to the (Function*) or function name of the resolver
from there? I tried everything with the Constant

Finding callees of a function
I searched the doxygen documentation and could not find a solution to my

What about mounting over nfs instead of the fuse client. Or maybe libgfapi.
Is that available for export domains

[ovirt-users] slow performance with export storage on glusterfs
Hello
If you use Gluster as FUSE mount it's always slower than you expect it to
be.
If you want to get better performance out of your oVirt/Gluster storage,
try the following:
- create a Linux VM in your oVirt environment, assign 4/8/12 virtual disks
(Virtual disks are located on your Gluster storage volume).
- Boot/configure the VM, then use LVM to create VG/LV with 4 stripes
(lvcreate -i

MEMDISK issues and Dell OptiPlex and Latitude systems
Hello all. Again I call upon the greats of this mailing list to help me with an issue related to MEMDISK - notably when paired with various Dell OptiPlex and Latitude systems.
The issue presented itself sometime ago and I best dealt with it by remaining with version 3.83 of the SYSLINUX package. But valuing the improved changes fostered by newer versions, I would prefer to move forward with

Centos laptop support
Today I found myself in need of a laptop to run Centos on. And that simple statement led to an all-day odyssey.
My original plan was to purchase a laptop and install Centos 6 on it. I went to Staples and tried booting it on every model of laptop that they had in the store. They all come with Windows 8 installed, and for the edification of anyone who doesn't know this (I didn't until

MonkeyPatching ActiveRecord::Base class
I am trying to monkey-patch the ActiveRecord::Base class to incorporate
a generic search class method so that it can be used by all model
classes which need this functionality. Since model classes directly
inherit from ActiveRecord::Base and unlike controllers and helpers, do
not have an ancestor class defined, I think I am forced to open the
ActiveRecord::Base class and patch it? May be I am

crash of xen-system when accessing cdrom
Hello together,
I already sent the message below to xen-users a few days ago, but didn''t get
an answer. So I hope that here on xen-devel is someone who has some ideas
(or is using XEN on this specific system and can confirm this isn''t a
problem within xen itself but with this specific BIOS or sth.
similar :-) ).
