Hi Duncan, when I run "opt -std-compile-opts" on the original source code it has the same output of O3. when I run "opt -std-compile-opts" on the -O3 optimized code, things get even more weird, it outputs the following code: while.body: ; preds = %while.body, %entry %indvar = phi i32 [ 0, %entry ], [ %indvar.next.3, %while.body ] %tmp

After a few more tests, I found out that if we set -unroll-threshold to a value large enough, and run "opt -std-compile-opts" or "opt -O3" 3 times, the unroll will be able to unroll the original loop 32 times, and when you have it unrolled for at least 32 times a optimization is triggered, folding it to a single "%xor.3.3.1 = xor i32 %tmp6, -1" (dont know why it does

Dear R users, I'd like to make this data rem.y = c(-1,0,2,4,5) from y = c(-1,-1,0,2,2,2,2,4,4,5,5,5,5,5). That is, I need to remove repeated values. Here is my code, but I don't think it is efficient. How could I improve this? #------------------------------------------------------------------------ y = c(-1,-1,0,2,2,2,2,4,4,5,5,5,5,5) n=length(y) for (i in 1:n) #

Hello, I'm trying to fill CID data into the astdb using AsteriskWin32's asterisk.exe, to no avail: The batch file stops after the first line, and just waits: ---------------------------------------- rem c:\cygroot\mystuff>import.bat rem rem c:\cygroot\mystuff>C:\cygroot\bin\asterisk.exe -rx 'database put cidname 123 "My cellphone"' rem rem Asterisk module

Dear R-users, When I call Rterm from cygwin, I have no options but typing the exact syntax the first time. If I happen to hit the "delete" key (backspace), R dies when I press enter saying : Error: ... (error concerning the function on the last line of text) Execution halted Perhaps some of you have experienced this and found work arounds? One has to be pretty good to type without

Hi, i'm having a serious problem with the following logon-script. It works under W2k, but not under W98, although W98 tells it is running startup-script .. First my smb.conf (only interesting parts) : ---snipp--- [global] server string = Samba-PDC %v on %h workgroup = WORKGROUP encrypt passwords = yes netbios name = 486dx66 domain master = Yes

Hi folks, I couldn't find a specific XOR (OR and AND) optimization on llvm, and therefore I am about to implement it. But first I would like to check with you guys that it really does not exist. For a simple loop like this: nbits = 128; bit_addr = 0; while(nbits--) { bindex=bit_addr>>5; /* Index is number /32 */ bitnumb=bit_addr % 32; /* Bit number in longword */

Hello all, Since the rsync on Panther many things changed in my professional life. This project is abandoned although it should work. But this you already know. What's new? On my new job I have several servers to administrate. Servers that aren't backed up (sic). So, there's why I'm back to rsync. The backup plan I would like: 1) Client side: PCs running rsync (or

Hi, Hopefully this isn't duplicating info. If so, sorry for the noise. I tried searching through old posts to this list about this issue, but couldn't find anything that worked. Below is a script I have put together that lets you rsync from a Windows 2003 shadow copy without having to copy files out of it first. You can link the shadow copy to either a drive letter or to a folder. You

Hi! I'm pretty new to using Samba and have come accross a puzzling problem that I cannot figure out with the documentation or Samba books... please forgive me if this has been discussed before in this forum, I have not seen such discussion. We have a customer that uses a script that basically maps to three samba shares, then uses the substitute command repeatedly. Every time a subst command

Please consider using 16-bit 16kHz (wideband) instead. It's a huge increase in audio quality and the bitrate is still very low, especially if you take advantage of Speex features such as VBR. 8kHz seems totally inappropriate to me for desktop streaming audio, let alone 8-bit samples. Or perhaps your recording equipment is an original Sound Blaster from 1989? (Even that could record at

hi, currently, the DAGCombiner unconditionally converts (DAGCombiner::visit(U|S)REM) expressions of the form X % C for constants C into X-X/C*C. this makes sense in certain cases where the div/mul logic will simplify X/C*X but is counterproductive in general, especially if the multiply is expensive. also, this doesn't allow targets to custom lower rem operations. shouldn't this

Hello While searching the archives and googling for : -login script to map drives according to group membership I saw lots of complicated solutions (on-the-fly scripts, group directories) etc. but the following works very well for me: I downloade dthe ifmember.exe from the microsoft website, and stuck it in the netlogon directory (not the scripts directory)

Dear All, Sorry to bother you again. I have a model: coxfita=coxph(Surv(rem.Remtime/365,rem.Rcens)~all.sex,data=nearma) and I'm trying to do a plot of Schoenfeld residuals using the code: plot(cox.zph(coxfita)) abline(h=0,lty=3) The error message I get is: Error in plot.window(...) : need finite 'ylim' values In addition: Warning messages: 1: In sqrt(x$var[i, i] * seval) : NaNs
