[LLVMdev] Instructions having variable names as operands
Dear Mr. Lattner: You have asked me how my instruction set works. If I code like this: int foo1() { int x1,x2; x1 =1; x2 = foo2(x1); return x2; } int foo2(int k) { if(k == 1) k = 2; return k; } int main () { int j; j = foo1(); } This should be emitted like this: Enter foo1; reg x2, x1 add 1;x1 Call foo2;x1,x2 Exit foo1; x2

Estimate region of highest probabilty density
Estimate region of highest probabilty density Dear R-community I have data consisting of x and y. To each pair (x,y) a z value (weight) is assigned. With kde2d I can estimate the densities on a regular grid and based on this make a contour plot (not considering the z-values). According to an earlier post in the list I adjusted the kde2d to kde2d.weighted (see code below) to estimate the

[LLVMdev] PBQP allocator progress.
Hi everyone, This is a quick status update regarding the PBQP (Partitioned Boolean Quadratic Programming) register allocator. A quick overview of the project: PBQP is a heavyweight allocation technique intended for native code compilation, and compilation of performance critical sections. It works by modeling register allocation problems as PBQP problems, solving these using a generic solver, and

[LLVMdev] LLVM assembly without basic block
Thank you for reminding me the notion of the basic block. Of course, I know all the assembly takes the form of BBs and is divided into units of BB. OK. It looks better for me to explain what I wanted to do more clear from the first. Actually, I am working on emitting out an assembly of VM by using LLVM. LLVM assembly looks similar with this VM assembly except BB. The VM assembly does not have the

LLVM and strict SSA
Hello to all LLVM Developers. The LLVM IR is in strict SSA form (i.e. every variable is defined before it is used along every path from the entry to exit point)? According to the documentation, currently the LLVM IR is in the SSA form, but I don't see additional information about *strict* SSA form. The strict SSA form provide opportunities of optimization in register allocation, because is

[LLVMdev] Greedy Register Allocation in LLVM 3.0
Hi Jakob, Yes. I have references. For example, from the top of my head I would name the following papers: 1)  A Generalized Algorithm for Graph-Coloring Register Allocation by Michael D. Smith, Norman Ramsey and Glenn Holloway      http://www.cs.tufts.edu/~nr/pubs/gcra-abstract.html 2) Register allocation by puzzle solving by Fernando Magno Quintão Pereira, Jens Palsberg

using "eval(parse(text)) " , gsub(pattern, replacement, x) , to process "code" within a loop/custom function
R-help users, Thanks in advance for any assistance ... I truly appreciate your expertise. I searched help and could not figure this out, and think you can probably offer some helpful tips. I apologize if I missed something, which I'm sure I probably did. I have data for many "samples". (e.g. 1950, 1951, 1952, etc.) For each "sample", I have many data-frames.

[LLVMdev] Unreachable code executed crash
Initially, tt was not a problem with the verifier, we were just inserting a wrong instruction in our pass. Also we were able to figure out the error you pointed out and our pass is running as intended!!! Thanks a lot.

zfs showing more filesystem using ls than df actually has
Platform T2000 SunOS ccluatdwunix1 5.10 Generic_125100-10 sun4v sparc SUNW,Sun-Fire-T200 I have a user that stated zfs is allocating more file system space than actually available via ls command versus what df -k shows. He stated he used the mkfile to verify if ZFS quota was working. He executes "ls -s" to report usage which reports more allocated than available from "df

We have talked about whole function instruction selection but does not have immediate plan to implement it. If we were to implement it today, it would probably be done on DAGs with

[LLVMdev] Code instruction selection based on SSA-graphs
Hi, LLVM already uses dynamic-programming based optimal pattern matching selectors for some of the target architectures. But as far as I know, the code is first converted out of the SSA form, before the selection process takes place. The same approach is used by many other compilers. But there is an article from Erik Eckstein, where a different method is proposed. In the described approach, the

remove 0 rows from a data frame
Dear all, As part of a larger function, I am randomly removing rows from a data frame. The number of removed rows is determmined by a Poisson distribution with a low mean. Sometimes, the random number is 0, and that's when the problem starts: My data frame: > temp occ x y dbh age 801 0 2977.196 3090.225 6 36.0 802 0 2951.892 3083.769 8 40.6 803 0 2919.111

Problem reading vitals from Gigabyte H77-DH3H
Hello everyone, I'm unable to read temperature Gigabyte H77-DH3H motherboard. Is that motherboard supported or am I doing it incorrectly? When trying to access hw.acpi.thermal everything appears to be ok, but it is not, the system always returns 27,8C and 29,8C which fooled me initially - the values never change. Here is output: [chinatsu]:/root# sysctl hw.acpi.thermal

Re: Installing Libguestfs
And yes the guest is running. We are creating folder of files and want to transfer all files present in that folder. We have host OS as ubuntu and want to transfer files in one particular folder to guest VM which also has ubuntu as guest OS.
