UTF-8 conversion speed
At CPPcon last week, I saw a talk by Bob Steagall called "Fast Conversion From UTF-8 with C++, DFAs, and SSE Intrinsics." Part of this talk included data from a half-dozen or so conversion libraries... one of which was labeled "LLVM". The LLVM converters were invariably the slowest. On Windows, the mbtowc (or something like that) syscall was pretty good. Steagall's converters...

Netbios ?
I am trying a "netstat | grep netbios" and receive nothing back. I tried "netstat | grep 139" and nothing as well. I have the correct netbios ports in /etc/services. Does anyone know to make this show up with a netstat or have those services running? I believe this may be my problem with the mapping of samba shares to the client. Any help would be appreciated, Dan

[LLVMdev] Google Summer of Code Idea
...to hear any feedback on these ideas, specifically, but in no particular order, with regards the following points: 1. Is this too ambitious for a google summer of code project? 2. Would implementing any of these algorithms be tricky due to some peculiarity of LLVM? 3. Do existing optimisations and DFAs that depend on aliasing information interface with the alias analysis in a context sensitive manner, or do they require rewriting? 4. Is anyone willing to mentor this project? Me: I am PhD student at the University of Warwick, England, where my current research is focused on specifying compiler o...

applying a set of rules to each row
All, I would like to apply a set of rules to each row of the sample data set below. The rule sets are the guidelines for determining an individual's date for retirement eligibility. The rules are found in this document, http://www.opm.gov/feddata/RetirementPaperFinal_v4.pdf. I am only interested in the top two categories for retirement eligibility, the CSRS and FERS plans. The data set has

Both are amenable to the same style of offline variable optimizations that Hardekopf, et al (Ben and a friend have been helping out with implementation of andersen's in LLVM), and that may actually make them usable for real world programs. > 3.

[LLVMdev] problem trying to write an LLVM register-allocation pass
I have a new problem: Register RBP is used in a function foo. (I am not allocating RBP to any virtual register, the instances of RBP in function foo are in the machine code when my register allocator starts.) Function foo calls function bar. Register RBP is not saved across the call, though it is live after the call. Function bar includes a virtual register. The code that I'm using to

Mapping Problem
All, The Windows 2000 client is on my side of the firewall (the error message is: "remote computer is not available"), the Windows XP client is on the other side of the firewall, (the error message is: "The specified network name is no longer available"). I am able to ping both the IP address and server name of the CIFS/Samba server. I cannot perform the mapping, via Map
