...ment we don't really see redundant ADRP yet. AArch64 is using ADDxxi_lsl0_s instead, and it will be folded into LS32_STR finally. Interesting. Looks like we are too clever here. I would have expected ISel to generate one base address and one displacement. I believe that if we fix that both the LOHs and the global merge become orthogonal. My guess is that we should be less aggressive at folding offset if there are several uses. > > Assuming you emit the right instructions at isel time, you will create ADRP, LOADGot, or ADD with symbols.

...on't see linker plug-in in LLVM trunk and it would be hard for me to verify any thoughts. The LOH solution is also orthogonal. You can see that as a last chance way to optimize those accesses. That said, if you CSE the ADRP and not the LOADGot, you will indeed create far less candidates for the LOHs because you will have ADRPs with several uses, which is not supported by LOHs. FYI, the LOH optimization is not a link-time optimization in LLVM, this is really a link-time optimization: on the binary. > > Any concrete suggestion of combining those different ADRP CSE solutions and tests wo...

This sounds reasonable. Thanks, all. > - CSE of ADRP optimization (Jiangning) Quentin may have some input here. He’s done quite a lot of optimizations for ADRP sequences. -Jim On Apr 12, 2014, at 12:08 AM, Tim Northover <t.p.northover at gmail.com> wrote: > Hi again, > > Having heard no howls of protest, those of us remaining on the > Wednesday decided to get down to

Hi all! It's great to start with "for dummies" question, but hey, we all have been human infants also =) Problem is, that I can not log on to this channel and I haven't found anything helpful during the past few days either. 1. The irc.freenode.net server gives me "Couldn't look up your hostname" and "No identd (auth) response" followed with

...ng that the AArch64CollectLOH-pass information and a linker > that makes use of that information could affect the profitability of > the GlobalMerge pass? It could, and does, from what I've seen (beware anecdata): - reusing the adrp base prevents optimizing it (the various Adrp*{ldr,str} LOHs). - reusing the adrp+add MergedGlobal pointer, with indexed addressing, doesn't prevent the AdrpAdd optimization. All in all, whether GlobalMerge is profitable or not (by increasing register pressure, or adding another indirection), whenever the LOH optimizations fire, they reduce its usefulne...

Hi Ahmed, Did you run these experiments on a platform with a linker that makes use of the AArch64CollectLOH-pass-produced information? I'm guessing that the AArch64CollectLOH-pass information and a linker that makes use of that information could affect the profitability of the GlobalMerge pass?

Hi, In addition to GADA, what are the available package in R and bioconductor to analyze amplification, deletion, LOH and indels of CNV, SNP data? Any reference is welcome. Best, Carol

http://www.youtube.com/watch?v=tDacjrSCeq4 I wonder if the inverse is true. If I whisper soothing words of encouragement at my JBODs, will I get more IOPS with reduced latency? :^)

I have tried to set up Samba on my Solaris 2.5.1 with 2 interfaces (le0, le0:1 - one network card with two IP addresses). But all I could see is throught the default ports 137 and 139. In my /etc/inetd.conf, I have: netbios-ns dgram udp wait root /opt/samba/bin/nmbd nmbd -s/opt/samba/lib/kes.smb.conf netbios-ssn stream tcp nowait root /opt/samba/bin/smbd smbd -s/opt/samba/lib/kes.smb.conf

It seems that the text command isn't working for a postscript device. Here is my code: #----------------------------- # I have stored some data in a 21 by 21 matrix called mat x <- 1:ncol(mat); y <- 1:nrow(mat); labs <- c(" ", "1298", "1537", "TP53", "786", "974", "1303", "1288", "1294",

Just another bit of info which might help solve this: Looking at the Asterisk log messages - I notice when I start up Asterisk, I see the error: pbx_config.c: Can't use 'next' priority on the first entry! Could I be right that its something got to do with priorities? I changed the incomingpstn context to the following eliminating the 'n' field and still the same errors were

Wondered about the best way to control for input variables that have a large number of levels in 'rpart' models. I understand the algorithm searches through all possible splits (2^(k-1) for k levels) and so variables with more levels are more prone to be good spliters... so I'm looking for ways to compensate and adjust for this complexity. For example, if two variables produce
