Will Arch Linux going to change the default compiler to Clang?

Recently read a news about building the kernel with LLVM Clang.
I would like to ask will Arch Linux adopt this also soon, or in a plan, or no decision yet?

Teho wrote:Would you mind sharing some sources? There seems to be quite a bit of work going on making upstream Clang/LLVM to compile Linux kernel
Same as you (I suppose) I've been following these attempts by looking at overall progress, mailing lists and some of the bug reports, like I said this is not the first attempt to get llvm/clang to compile Linux (afaik this latest one is a consolidation of previous efforts together with some new blood(?) which makes it more likely that it will atleast be able to compile a stable kernel, albeit requiring patches).
Teho wrote:Debian also seems to have plans to compile their entire repository with Clang. Not to mention that LLVM itself is very popular nowadays being installed on almost every Linux system.
Are you referring to that one Debian developer who has compiled the repository with Clang to see how well it went? Is that the basis of your 'Debian also seems to have plans to compile their entire repository with Clang' claim?. AFAIK developers of distros have tried pretty much all the compilers under the sun on their repos and have reported the results, doesn't mean they plan to use that compiler for their official builds.
Teho wrote:To my understanding the patches applied to Linux are also relatively small and non-intrusive.
I don't know what the state is now but the previous patches I recall where not unintrusive, of course there are two targets of problems here, you can pretty much leave Linux alone if you can have clang-llvm accept lots of patches, and vice versa. If the current crop of patches needed were relatively small and non-intrusive they would likely have made in into some testing branches in the trees of their upstream targets by know, the changes needed for FreeBSD to compile using Clang/LLVM were quite substantial as I recall and it was like a 4-5 year period necessary for the transition despite being a very focused effort which will finally reach it's culmination with the upcoming FreeBSD 10 release.
Teho wrote:There's obviously a lot of community intrest considering that it was worth setting up the LLVMLinux project under Linux Foundation (to reduce dublicated work);
Well I don't judge a project's success or community interest by a webpage, I judge it by progress. Currently it seems to be where it was last I checked, patches needing to be applied to both Linux and Clang/LLVM with a unstable kernel as a result.
Teho wrote:Not to mention that LLVM itself is very popular nowadays being installed on almost every Linux system.
Well yes LLVM is pretty much ubiquitous as a JIT-framework which is used in lots of projects but LLVM as a an actual installed package?
Like I said, I would be surprised (as in I don't think it will happen) if upstream linux and clang/llvm took in the patches necessary for compiling linux 'out-of-the-box' based upon past and current progress. I guess we'll have to see.

    For sideloaded content the nook pulls the metadata from ePub file itself.  I would suggest looking at a program like Sigil or Calibre that will let you edit the metadata in the book to make it appear like you want.
    For the PDF vs ePub - No, that's the way PDFs work (think of them as graphics, not text), wheres ePubs are Web Pages - so  no you can't them to behave exactly alike without converting the files.

  • Will migration assistant change the default display settings on my new Mac?

    I just set up a new iMac and used Migration Assistant to load from my Time Machine. But now the display looks muted and not as bright. Would Migration Assistant change the default display settings on my new Mac?

    Migration Assistant may not be the cause. But you should reset the NVRAM and see it that fixes the issue.
    Shut down your Mac.
    Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
    Turn on the computer.
    Press and hold the Command-Option-P-R keys before the gray screen appears.
    Hold the keys down until the computer restarts and you hear the startup sound for the third time.
    Release the keys.

  • On my macbook pro, where is the file for the original default desktop wallpaper? ...and if i replace this will it change the default wallpaper?

    Whenever I lock my screen on my mac (by closing the lid) the login screen I see on reopening my computer is a faded version of my desktop image (which is normal, and fine) however when I close my laptop while it's in fullscreen mode (when I'm using a web browser or other application in full screen) the lock screen displays the default desktop image, which is what i'm trying to change. My macbook has always done this.
    My computer is running Mac OS X version 10.7.3
    I've been looking for a way to change the default wallpaper on my mac, so that when i lock my screen in full screen mode the lock screen displays my selected wallpaper image (the same one as is on my desktop) instead of the default (andromeda galaxy). Can anyone please provide me with the location of the default image file (if it's even accessible) or maybe even provide me with a way to fix this? Any help is greatly appreciated!

    Hi Mr. Wog,
    My guess is that once you see an estimate for replacement for hundreds of dollars, those scratches won't look too bad anymore. There are products to cover the outer casing, and some people put stickers on, or even paint (I don't recommend either, but ymmv). Good luck.

  • How to change the default font size in X11?

    I was a PC/linux user and have switched to use Mac lately (MBP Snow leopard 10.6.8).
    Everything's been running perfectly on Mac so far and I really like it, until I have to run some programs on XQuartz/X11 (XQuart 2.7.0).  
    The default font size in the Xterm is too small. And I hate it that I have to change it everytime i open a new terminal (via vt fonts menu, ctrl+right-mouse click).
    Is there a way to change the default font size "permanently" in XQuartz/X11 ??
    This may be a stupid question to ask in the developer forum but i cant really solve it.
    There's only config. file ~/.Xdefaults they have mentioned so far on Google but i really cant find it regarding to the directorty.
    Thank you very much in advance.

    You would be surprised to find out that is not like this, to get your account blocked you really need to do a lot of damage and posts are not removed unless they are illegal, and *always* it needs more than a person to delete something. That's a site managed by the community, not by some people put in place by a company.
    It is always acceptable to link to external resources as long these resources do provide additional usefull information. Clearly the thread on that side contained much more information than the one here. I observed people linking from there to this forum, but it's not so common, and that's not due to the policy, just because here is more chat and less usefull information.... you will not see endless threads of replies on with "yes, I have the same problem" there.
    Shortly, this is "discussions" and is quite different in approach than the SE model, where everythign is aimed towards getting the be answers UP and removing all the nonsense.
    I wish that Apple would invest more in discussion, and going towards making this more practical.

  • How to change the default BC image that shows in the address bar?

    Does anyone know how to change the default BC image that shows in the address bar? I want to swap it out so the client logo shows next to their URL.
    Thank you!

    Hi,
    If you are trying to change the favicon for your site,
    You can do it from Site Manager-> Page template -> Default Template
    Look for the code   <link type="image/x-icon" href="/Path for your image" rel="icon" />, and Click save.
    Now where you will use this template, it will display your favicon for that webpage instead of BC favicon. You can define it on Page directly if you are not going to use template.
    Please let me know if you have any doubt.

  • Changing the default download settings in the excel.

    Hi All,
    Is there any methodology to change the default settings of the download of a report to a excel file. Because when I try to download reports having pivoted chart view it tends to hide the titles. I have added the padding but no luck. It is taking the default settings.
    Is there any xml file where we change those properties?
    Thanks:

    George,
    Thanks a lot, that is very helpful.
    To solve my problem I am going to use that method (Create a new file @ startup, see if it exists, and if it does not exist then it is the first time running) and tweak it a little to solve my exact problem.
    I need to be sure that the application is being run after installation (from the installer), because the user MAY select "do not run after install", in which case the first time they try to run the program by opening an associated file, the program will exit, which is not a good first impression to leave on the user.
    So I will check if the file exists created and if then i will check if arguments (file name) is being passed.
    1. If a file name argument is passed I'll create the file and continue running to program. - First time run, but not from installer.
    2. If no argument is present and it is the first time, I will shut down immediately with no message. - First time running/run from installer.
    3. If no argument is present and file exists, exit with error (file needed). - Not the first time run, but no argument passed.
    4. If argument exists and and file exists, run program. - Normal execution.

  • How do I change the default POP account directory (~/Library/Mail)?

    With Mail 1.0 in 10.3.9, I could change the default ~/Library/Mail storage location for a POP account. I did this by setting up an account and in the advanced tab choosing a path.
    With Mail 2.0 in 10.4.4, when going through the guided account setup, the directory option is no longer available. But the option still shows greyed-out, so I assume it's possible to change.

    How do I get my POP account to store somewhere else?
    G4 1.25 MDD   Mac OS X (10.4.4)  

    hmmm.. I've been complaining about this to the engineers for over a year. The storage location should be chooseable as should there also be a backup feature (as in Addressbook and iCal).
    for those that want to change this... it would be cool for someone to write a non cryptic, complete 1,2,3 stepped procedure.
    That is.. exactly what do you change to what in the mail user preference file? And what do you use to change it.. text edit? "[ ]" heretofor = folder
    I would like to change my Mail storage location to the my [Documents] . Using Text Edit, I went into my user [Library], to [Preferences] and opened the com.apple.mail.plist and changed all the ~/Library/mail storage locations to ~/Documents/Mail
    lastly I moved the [Mail] that was in the [Library] to my [Documents].
    Didn't work. Restarting Mail got me into the guided set a new account (and as far as I can see there IS no way of not taking the guided set up as alledged above). There must be something, some built-in direction other than in the [Preferences] defaulting mail to be saved in the [Library] folder
    If someone has done this and been successful.. a 1,2,3.. list would be apprecaited... and please don't leave any details out. Thanks

  • How do I change the default application to open files.

    I am rather new to Mac OS (using Leopard). I am rather frustrated, that I have not been able to find a way to change the default application that opens PDF files. I looked around the System Prefernces, couldn't find it, searched the Web, nothing. And I could not find an answer in this forum either.
    So here is my question. How do I change the default application for opening PDF files from Preview to Adobe Reader? I do not want to have to click "open with" every time, I want to open a PDF file.
    And how do I do this for other files also? For instance, I may want to open images files with Photoshop instead of Preview.

    Hey ! I was going mad with the same question - and I'm not a complete newbie - so thanks to William for answering it - I knew I'd seen that dialog somewhere, but just couldn't find it. Text edit was driving me crazy telling me that .ppt files were screwed, now I've got em to open with Powerpoint...
    In answer to your last question, Craig, the dialog that appears to ask if you're sure specifically says the change will relate to all .pdf files ( or .ppt or .whatever ), so it won't stop Preview from opening other types of files.
    Thanks for the help - searched Apple support in vain on this one...

  • How to change the default new project folder in Premiere Elements 13?

    I keep all my projects on a different drive than the default My Documents folder. How can I change the default setting so that Premiere Elements does not try to create new projects in the My Documents\Pemiere Elements\13.0 folder? In fact, I do not want that folder to be used for anything (including layouts and styles).

    steveb
    Short version....
    Referring to the 13.0 Folder in the Adobe Folder in documents, you wrote
    In fact, I do not want that folder to be used for anything (including layouts and styles). 
    I do not believe that is possible.
    For my best case scenario
    Set the Scratch disks, not to Same As Project, but set for Custom with the set being the save location that you set for the project file.
    Set the project save in, my preference, File Menu/Save As.
    You are going to end up automatically with a 13.0 Folder in the Libraries/Documents/Adobe/Premiere Elements/13.0 Folder every time you open a Premiere Elements project. No matter how many times you try to delete the 13.0 Folder. And that 13.0 Folder will contain a Layout Folder and, if you applied a Style in the project, a Styles Folder.
    Longer Version....
    There is no problem directing your project file to the save location of choice. You can do that two way
    1. After you open the project to the Expert workspace, go to File Menu/Save As to change the name of the project as well as the location for the save in order to avoid the defaults.
    2. You can also do that through File Menu/New/Project.
    That 13.0 Folder also gains its contents from the settings of the scratch discs in Edit Menu/Preferences/Scratch Disc - some examples preview files, disc encoding files, conformed audio files... Some Files/Folders are placed there automatically. So what to do to keep the Documents area clear of Premiere Elements files, project or otherwise after you have move all that you thought you could to a non Adobe default location? See above best case scenario.
    Miscellaneous
    1. If you set the save location of the project in either of the 2 ways, that setting will not hold from project to project. It will hold for that particular project.
    3. If you set the Scratch disks in Edit Menu/Preferences/Scratch Disks, those settings seem to hold from project to project as well as for in the particular project.
    Stevenb, please review and consider and verify. I have gone through several scenarios on what you would prefer. But, I do not see a way to make that happen with the programming that exists.

  • How do I change the default window color?

    Having white screens is too bright for my eyes!! I always change the default window color in Windows (hiss hiss) to a light shade of gray and that setting carries thru to all windows (i.e. Word, Excel, notepad....). Is it possible to do a similar thing with Tiger? I see that I can choose between a couple of "schemes" from a "Desktop and Dashboard Settings" area (or similar - i don't have my mac here now so can't look to see the proper name) but I see no way to alter colors within those schemes. If you can tell me how to change the default color for my windows I will be awfully happy. thanks.

    Personally, I wouldn't trust it, and I don't hesitate to try these things most of the time even though they sometimes cause problems. But I've used Unsanity products before and they all require installing a preference pane called APE; Application Enhancement module, and that thing caused me lots of problems for my system, lots of crashes and flakiness. I won't use it again.
    But I'm sure there are lots of people using it happily, but if you don't feel confident in dealing with system problems stay away from anything that adds a system preference pane or goes up in the top menu bar at the top (Apple icons excepted) or has to start up with the system.

  • How do I change the Default number of pings?

    I know that using -c will temporarily set the number of pings issues for example:  "ping -c 5 192.168.1.50" would issue 5 pings.  My issue is that if I don't use the -c option (i.e. ping 192.168.1.50), my terminal issues an endless number of pings and it continues to do so until I manually stop the command.  I'm not even sure if it would ever stop or just keep going.
    In most cases this is not a big deal because I can easily use -c to set the desired number of pings.  However when I try to issue a broadcast ping for my LAN which is "ping 192.168.1.255" the command pings the First host that is connected, and continues to ping that same host over and over until I stop it and it never pings any other host besides the first, and my broadcast ping never works. 
    I really only use the broadcast ping to update the Arp cache before issuing an "arp -a" or something similar, however, it would be nice if I could change the default to something low like between 5 and 10 pings, so that even if I don't use the -c option the count will be low!
    Does anybody know how to make this adjustment?

    ComputerG,
    the ping command in OS X does not have an option to change its default  count. If the -c count option is not provided on the command line, the unchangeable default count is infinite (i.e. keep pinging until interrupted).
