reg2mem does not eliminate phi nodes the way codegen does, it just converts ssa values to non-ssa values. It's not the same thing.

Hi, Daniel I want to profile load/store operations, in order to reduce the overhead of profiling, I try to instrument the optimized llvm ir, which has phi nodes. BTW, when the value of some load/store operations may have multi-source, then the load will be translated into phi nodes, and all phi nodes are placed in the front of BB. Sometimes, the position is not where the load happens, is there

Hi all, I'm having trouble getting access to the pwr. This is on Ubuntu Lucid Lynx, 64 bit. I'm installing pwr via packages.install('pwr'), and loading it via library(pwr), both of which appear successful. Strangely, I never get access to the pwr object in R. I tried installing it to /usr/local/lib/R/site-library and ~/R/x86_64-pc-linux-gnu-library. I also tried installing it

Thank your reply. Pankaj. Actually, I have done it very similar to yours. But I think for my demand, it is better to implement in Front End. Maybe I will re-implement it later in clang. ---------- Forwarded message ---------- From: Pankaj Gode [via LLVM] <ml-node+s1065342n59345h22 at n5.nabble.com> Date: Mon, Jul 15, 2013 at 2:35 PM Subject: Re: Regarding scope information for variable

Craig, Thanks for your follow-up note on using the asypow package. My problem was not only constructing the "constraints" vector but, for my particular situation (Poisson regression, two groups, sample sizes of (1081,3180), I get very different results using asypow package compared to my other (home grown) approaches. library(asypow) pois.mean<-c(0.0065,0.0003) info.pois <-

Dear R experts, I have conducted a power calculation in order to estimate the number of subjects needed to detect an effect size of d=0.28 (cohen's d) for a difference between two independent groups (alpha level should be 0.05 and the effect should be detected with 80% probability). The results from the code below indicates that I would need n=400 subjects (200 in each group). This is seems

Hi, all When compiling a program with -g -O0, and if we have a PC, then with addr2line, we can get the line number of the instruction. My quesions are: what is the result of Phi node instruction, can we get the similar results ? -- Best Regards! Eric Lew -------------- next part -------------- An HTML attachment was scrubbed...

Hi Eric,  I was considering machine instructions to get scope information. And variable declaration does not correspond to machine instruction, hence the problem i.e. no scope associated with it. If 'i' is initialized in the 'if-scope' then we get 'variable i' mapped to correct scope as corresponding machine instruction is generated for this. This is not a problem as we

Hello, I've encountered a very weird issue with the method subset(), or maybe this is something I don't know about said method that when you're subsetting based on the columns of a data frame you can only use constants (0.1, 2.3, 2.2) instead of variables? Here's a look at my data frame called 'ea.cad.pwr': *>ea.ca.pwr[1:5,] MAF OR POWER 1 0.02 0.01 0.9999 2 0.02

1) Build clang with GCC-4.9.2, when compling other application s with clang/clang++, the default linker is ld, can I replace it with other linker tool， if we can, how to do it? I.E. can we use collect2 instead? 2) how to specify the path, if we do not use the default vertion GCC? Best Regards!

Hi, all I want to instrument load/store operations in LLVM IR. And I find the LLVM IR generated with flag -o3 is much more efficient than -o0, so I try to instrument on these optimized LLVM IR, but, some load operations are changed to Phi loads. Then, I try the -reg2mem flag to remove these phi nodes. The problems are: 1) I use visitLoadInst to collect these load operations, and it seems I

Hello guys, I've prepared a patch based on my findings for the bbswitch module (https://github.com/Lekensteyn/acpi-stuff/tree/master/bbswitch). This adds a proper check whether a _DSM function is supported or not and make OFF / ON for vga_switcheroo work for nVidia Optimus models. The patch is based against the mainline kernel. It has been tested on my Clevo B7130 laptop running kernel 3.2

I have an unbalanced design I would like to run a power analysis on. What I have been able to find has pointed me to using the pwr.f2.test function as described below. My problem is that I don't know how to appropriately define the numerator and demoninator df. If someone can help here is some more info about my design. It is an unbalanced 2^3 x 3 design where the factor with 3 levels is a

Hi, Ben gcc version is: 4.7.0 clang version is: 3.2 The command options are: 1) clang generated object files: clang -O3 -c *.c -o x.o link: clang *.o -lm -o mpeg2enc 2) gcc generated object files: gcc -O3 -c *.c -o x.o link: gcc *.o -lm -o mpeg2enc Yes, maybe it is the config introduced problems, I build it with enable debug options.

Hi, I am trying to sort out a discrepancy between power calculations results between me and another statistician. I use R but I am not sure what she uses. It is on the proportions test and so I have been using pwr.prop.test. I think I have tracked the problem down to pwr.prop.test not using the continuity correction for the test (I did this by using the java applet from
