Hi all, I had a look at the interprocedural optimizer. In my opinion the routine 'GlobalOpt::ProcessInternalGlobal' is a little bit to conservative. It removes global variables if the only routine using this variable is main. Typically this condition is valid only for very few global variables. Here is a code snippet containing the test before the transformation: file:

Hi, i am currently trying to code a little netfilter plugin, to be placed into the bridge forwarding path. In such plugin, i would like to test if a packet is: - unicast - multicast - broadcast The starting condition is that the bridge has no knowledge of the IP configuration of the sending and receiving stations. It does not know about their netmask e.g. I have tried the following function

Hello all, My question: - - - - - - - Does anybody know when the reverse path filtering occurs as the packet traverses the kernel? Does it happen before NF_IP_PRE_ROUTING (PREROUTING) or not? Does it only happen at route selection time? What I have tried to do to find the answer: - - - - - - - - - - - - - - - - - - - - - - I find a posting (from many years ago) [0], which suggests that this

Hi all Iam trying to implement "route add " using netlink. The changes are not reflected in the routing table. I have given my code and screen shots of the routing tables. Can anybody tell me is there any mistake iam making in defining the fields . or any other mistake iam commiting thanxs viji //////////////////////////////////// CODE

Hello, I am working on the the "Global Variable Optimizer" pass. I'd like to modify this pass to be more aggressive. Therefore I need the call graph. The call graph contains AssertVHs of all functions. If the "Global Variable Optimizer" pass identifies a function to be delete able it will be deleted immediately by this pass. The call graph is not destroyed before.

Hello, I had a look at the global variable optimizer. In my opinion it handles a few special cases, when global variables can be replaced by local variables or be removed completely. Basically I think that this problem could be solved with an interprocedural live value analysis for global variables more generally. An assignment to a global variable can be removed, if this global variable is dead

Hi developers, I have some problems using a non-default alias analysis. I wrote a modulepass which needs a functionpass. The functionpass needs a type bases alias analysis instead of the basicaa. I added the command line parameter for this analysis to the opt invocation as follows: opt -tbaa -global-live-values test.bc The 'global-live-values' pass preserves all and requires a

Hi LLVM-Developers, I am looking for an analysis which figures out, if via function argument dereferencing a given value can be modified within that function. Or stated differently: Is in a called function an alias to a given value being modified? The current Basic Alias Analysis seems not to support values in different scopes, so I can't use it for this purpose. Is it supported by a

Dear LLVM developers, I have a question regarding the IPSCCP class and the handling of dead blocks: The file lib/Transforms/Scalar/SCCP.cpp of llvm 2.8 from contains some code to deal with a dead block which could not be folded (line 1909ff). This happens when a user of this dead block is a branch or switch with an undef condition. The action taken than is to replace this terminator with an

Has anyone managed to combine bridged network model and SNAT? I have a machine that just ssh''s into other boxes and updates via rsync a copy of their filesystems. I figured I could stage a xen VM for this server with a private IP address and do SNAT and "routing" via the dom0 box, but I get a wierd "Performing cross-bridge DNAT requires IP forwarding to be enabled"

Hello, I have finished setting up the load balancer with IPROUTE ... also patch the kernel to support DGD and now it''s working fine with the valuable guide at LARTC website, Julian Anastasov, and the kind people in this mailing list. Now I would like to launch a web server and a ftp server to the public but I''m stuck into a problem and really need your help. Currently internal

Hello, I am successfully connecting my Windows box to a RHEL 5 over SMB. This works for both mounting a regular share as well as (my own implementation of) a FUSE mountpoint. On RHEL 6 I can only mount a regular share, but not a FUSE mountpoint. I am getting a Permission Denied error. On both machines I have disabled firewall and I set SELinux to permissive. Does anybody know why this

Hi, I would like to know if the upload-progress functions available in Rails 0.14.3 are the most up-to-date available ? I have some strange behaviour and would like to know if I am on the code edge before digging in the code. (I see many upload''s just doing nothing; mostly the first upload works; the following don''t ... ) regards, -- Bart Duchesne

Dear R users, According Brockwell & Davis (1991, Section 9.3, p.304), the penalty term for computing the AIC criteria is "p+q+1" in the context of a zero-mean ARMA(p,q) time series model. They arrived at this criterion (with this particular penalty term) estimating the Kullback-Leibler discrepancy index. In practice, the user usually chooses the model whose estimated index is

I used to run the julian function from chron but this new version of R has also a julian function in the base package that doesn't do exactly what I need. Is there a way of telling R to run the function from chron and not from base? Thanks, Fernando __________________________ Fernando Colchero Doctoral Fellow Duke University Department of Ecology

I''m havign a HUGE amount of difficulty getting shoreline to work with LVS. We use it here constantly so we know it works. The problem is packets come in, get directed to a webserver, webserver returns the packet to firewall, and then it goes into a black hole. rp_filter is off globally on all interfaces. LVS seems to be working right.... I use shorewall tcrules to mark packets on

In http://www.ssi.bg/~ja/dgd.txt I read: -- - key "gw" for ip_route_output used to select the right route for the gateway - key "lsrc" for ip_route_input used to find the best unicast route between this IP and the destination address (similar to output routing call but still makes the checks needed for input packet). -- Could someone please provide a couple

With the ATI bug I was hitting earlier fixed, only my btrfs partition continues to show high cpu usage for some operations. Rsync, git pull, git checkout and svn up are typicall operations which trigger the high cpu usage. As an example, this perf report is from using git checkout to change to a new branch; the change needed to checkout 208 files out of about 1600 total files. du(1) reports
