How to prevent llvm's default optimization
Hi, James,
Thanks for your reply.
I do not think it is always true, that "mul then add" is faster than "add then mul".
For example,
A small immediate can be directly encoded in the instruction, but it becomes a larger one after a multiplication, which has to be loaded from the constant pool (extra memory access).
So I wonder, is it possile to prevent it, via changes

How do I identify the initiating View from within a Helper?
I would like to call a helper method from my View to construct a sidebar
menu. The menu is contextual, so ideally I would like to do something
like this:
View
----
<%= sidebar_menu %>
Helper
------
def sidebar_menu
case _calling_view_
when ''_view_identifier_''
... build menu...
end
end
where ''_calling_view_'' is the key that points to the

Question about Distinguishable Permutation
Hi,
How can I list all possilities of Distinguishable Permutation by R? For example, N=6, n1=n2=n3=2, the total possible answers are 6!/(2!2!2!)=90.
Please help me.
Thank you So much.

How to prevent llvm's default optimization
Yes - this has been in InstCombine for a long time:
https://github.com/llvm/llvm-project/blob/master/llvm/lib/Transforms/InstCombine/InstCombineMulDivRem.cpp#L268
We could say that the canonicalization should be reversed, but that
probably uncovers more missing optimizations.
The code size concern is legitimate. For example on x86, gcc asm is 2 bytes
smaller on this example:

How to prevent llvm's default optimization
Thanks. I have checked the hook DAGCombiner::isMulAddWithConstProfitable
And I think the above condition is too aggressive.
// If the add only has one use, this would be OK to do.
if (AddNode.getNode()->hasOneUse())
return true;
Shall we make it to
if (AddNode.getNode()->hasOneUse() && TargetLowering.isCheaperCommuteAddMul(......))
return true;

Re: How do I identify the initiating View from within aHelper?
Lindsay,
Wouldn''t you want to use a component for this? I know components seem
to be out of favor, but they seem like a perfect fit for this very
thing.
You could then go like:
<%= render_component :controller => ''sidebar'', :action => ''home_menu'' %>
The :action parameter could even be more dynamic based on your own
needs.

'trim' means discard?
Currently we cannot support discard on block storage since ovirt may need
to wipe
lvs when deleting a disk, and discarding may leave unwiped user data.

No domain server was available to validate your password.
Hi all,
I have a strange problem with the Samba server as PDC.
I periodically get the error message "No domain server
was available to validate your password". But, at
other times it would login fine and execute the login
scripts to handle all the map drives.
I don't have the slightest clue where the problem is.
When the problem arise, I don't even need to do
anything about it.
