I posted a similar issue, but this relates to how to keep a function call from being lowered to an ISD:FABS. In this case, I don't want FABS (floating point absolute) to be converted into an operation). In this case, what happens is that clang generates the code for floating point absolute (fabs) as a subroutine call: %5 = load douuble %x, align 8 %call = call double @fabs(double %5) nounwind read...

When we add -ffreestanding the compiler won't get to inline this any more.

...I think the only way to find out how speexdsp has been compiled is to resample some bytes and observe the output; which is awkard I plan to post some patches in this direction shortly... thanks, regards, p.

Hi As I''m more familiar with cfengine and it''s way to split updates (in update.conf) from the actual grunt work (in cfagent.conf), I''m wondering how to best manage puppet and my manifests with puppet...? Should I define a puppet class that copy the puppet package (in .tgz format) and all the manifests to the client, and then have all my other classes depend on

Hi, When I try to specify a file I want copied in place, like: configfile { "/etc/init.d/puppet": source => "config/apps/puppet/puppet" } and has a require on that later on: exec { "/usr/sbin/update-rc.d puppet defaults": require => "/etc/init.d/puppet" } puppetd throws an error: err: Could not find type

Hi, I''ve setup my systems to do reporting as explained in https:// reductivelabs.com/cgi-bin/puppet.cgi/wiki/ReportsAndReporting, with tagmail defined as one of the report types - but I do not recieve any mail at all. I''ve configured a tagmail.conf file like this: all: root@localhost But the documentation mentions three options, namely sendmail, reportfrom,

Hello, DVD Fab HD Decrypter is a DVD copy program. The free version is limited to decrypt and store the result onto HDD only. Better than all other tools (that I tried), this program does not have problems with some tricky copy protection methods. While the best other program fails on about 50% of current DVD movies, DVD Fab HD Decrypter took them all fine. I tried to run DVD Fab HD Decrypter

Hi I''m anxious to get puppet into production, and although I''d prefer installing puppet as a .deb package (as most of the servers in our shop runs Debian), I think I''ll try to get some of my not-so- important servers into my test setup by installing puppet with the .tgz files. Upon the first installation I realize that puppetd and puppetmasterd is copied to

Hi all I''ve stumbled upon something that I consider a bug: Node variables can''t have dashes in them: node blah { $allow-from = "127.0.0.1" } err: Could not parse; using old configuration: Could not match ''- from'' at /home/mercurial/repositories/manifests/nodes/nodes.pp:8 I''m using the variable to create a template-based config file.

Hi, I''ve just finished my first attempt at making anything in ruby. It ended up beeing a module to facter, which collects facts about the number of domU''s and the memory, id and vcpu facts on all of the domU''s. It''s meant to be run on the dom0, and uses the xm utility to get the information. The only thing I haven''t figured out, is how to

Hi, i have running samba with ldap as a PDC. The PDC works fine, except adding new computer to the domain. The Computer how was added 2-3 Years ago works fine, but i cannot add new PCs to the domain.

Hi I''m wondering if it''s possible to define some defaults for the package type. What I want is that package install/updates only happens at certain times of the day. I could do: class shorewall { package { "shorewall": ensure => latest, schedule => maintenance } } for every package I want to manage. But that means I have to type
