Hi, I noticed a bunch of psuedo instructions used for creation of constants without generating loads. e.g. pxor xmm0, xmm0 Here is an example of what i am referring to snipped from X86InstrSSE.td: def FsFLD0SS : I<0xEF, MRMInitReg, (outs FR32:$dst), (ins), "", [(set FR32:$dst, fp32imm0)]>, Requires<[HasSSE1]>, TB, OpSize; My question is

Instrinsic llvm.memory.barrier does not work as expected. Is it a bug or it has not been implemented yet ? (1) false arguments do not work // pesudo code void foo(int *x) { x[2] = 10; llvm.memory.barrier(0, 0, 0, 0, 0); x[2] = 20; return void } The barrier is actually noop, but it prevents "x[2] = 10" from being deleted. (2) True arguments do not work. // pesudo code void foo(int * restrict x) { x[2] = 10; llvm.memor...

Don't do that. :) Really, why are you using a noop barrier...

...aaberga@epsilon-stargate:~/sources/voip/zaptel-1.0.6> ls /dev [....] z2ram zap1 zap2 zap3 zap4 zapchannel zapctl zappseudo zaptimer zero zkshim zqft0 I edited the list to avoid a huge message. As said I am not a Linux low level expert ... still it's striking that Asterisk does not find a pesudo file /zap/channel and there is something similar, ie zapchannel. Anyways the zaptel modules are there: aaberga@epsilon-stargate:~/sources/voip/zaptel-1.0.6> cat /proc/modules wcfxo 11808 0 - Live 0xdf2a8000 wcfxs 27680 0 - Live 0xdf2b1000 zaptel 176772 2 wcfxo,wcfxs, Live 0xdf2ba000 Does anyb...

Hi R users, Sorry for a simple question: I found different people use different i in set.seed(i), are there any rules to choose an i or one can choose as he likes? Thanks Xiaohua

I can't be the first person to think of this, can I? But I couldn't locate any reference on this combination. If you know of one, please tell me.

I am using Ubuntu 10.04 and ruby-enterprise (not ubuntu ruby) and installed puppet via gem. How can I install puppet-dashboard if I don''t see a gem available and if I use the ubuntu package, i get the whole slop of ruby packages sucked in (which i am trying to avoid)? # dpkg -i puppet-dashboard_1.1.0-1_all.deb Selecting previously deselected package puppet-dashboard.

Hi! I have a recipe that''s supposed to download ree from a master and install it. It looks like: # Install ree file { "/root/puppet-setup/ruby- enterprise_1.8.7-2010.01_amd64.deb": source => "puppet://$servername/files/ruby- enterprise_1.8.7-2010.01_amd64.deb", mode => 0644, owner => root, group => root, notify =>

hi everyone, so,first it seemed a trivial question to me, but since I could not find anybody being neither able to answer this question nor giving a short config example. after a few sleepless nights and exhausting all the reading and research. here I am sharing my problem with all of you, in the hope of some possible solution/sugestion. or is it that this is impossible?? below my
