Suppose I have x<-data.frame(v1=1:4, v2=c(2,4,NA,7), v3=rep(1,4), v4=LETTERS[1:4],v5=rep('Z',4)) or a much larger frame, and I wish to test for and remove the constant numeric columns. I made: is.constant<-function(x){identical(min(x),max(x))} and apply(x,2,is.constant) # Works for numerics x[,-which(apply(x,2,is.constant))] I'd really like to be able to

..., %NOREG %r11 = LDR <fi#3>, %NOREG, 0, 14, %NOREG %lr = LDR <fi#2>, %NOREG, 0, 14, %NOREG %sp = ADDri %sp<kill>, 36, 14, %NOREG, %NOREG BX_RET 14, %NOREG, %r0<imp-use,kill> The problem is the def of %r0 right after the BL. %r0 is killed at the BL but is also implicitly defed and not marked dead. I believe it should be marked dead at the implicit def, similarly to %r1. Is that right? This is probably a bug I introduced but I want to make sure it actually is a bug. -Dave

We have run an experiment in which we set all physical register limits to zero. The purpose of this experiment was estimating the potential impact of getting complete liveness info. The results of this experiment were better than the results that we got using the real physical limits (the total number of spills in CPU2006 was reduced), but the difference was not substantial. We took this as an

Hi, I can't read a environment variable in a asterisk dialplan. When logged in as user root on the system an 'echo $HOSTNAME' gives the hostame of the machine. Asterisk (1.4) is started from the same console. I try to read it like this: exten => s,n,NoOp(host=${ENV(HOSTNAME)}) Does anyone know what i am missing? Ipv een saaie e-mail een leuk videobericht? Ga naar

....reset(i); (gdb) p i $179 = 145 (gdb) p /x KeepRegs.test(145) $180 = 0x1 * 145 is the value of T9_64. In CriticalAntiDepBreaker.cpp, there is a comment " Also assume all registers used in a call must not be changed (ABI).", but T9_64 is changed here. Also it says "registers that are defed but not used in this instruction are now dead", but I don't see the code that checks whether T9_64 is used. -------------- next part -------------- An HTML attachment was scrubbed...

The prospect of people actually putting B-format audio (via the panner or directly input) into Ogg/Vorbis brings an interesting challenge: What do we do with the audio after decoding it? The following sane options exist: A) Simply output the B-format audio B) Produce a downmix 1) Mono. 2) Stereo blumlein crossed pairs 3) Stereo UHJ 4) binaural C) Produce speaker feeds 1) Fully

All, I have just finished uploading the source release for FLAC 1.0.4 beta to Sourceforge; there are no binary releases. See the included doc/html/news.html for the changes since 1.0.3; there are quite a few. http://prdownloads.sourceforge.net/flac/flac-1.0.4_beta-src.tar.gz?download Please beat up on this as much as possible in the next week or two and try and turn up bugs. Here's a
