This sounds like a great idea. LLVM definitely lacks some profile-driven optimizations. -- With best

Hello, I am a final semester Dual Degree( B.Tech. M.Tech.) student from Indian Institute of Technology, Kanpur. I was looking forward to participate in this year's GSoC 2009.Starting Fall 2009 i shall be pursuing a Phd in compilers. I am having a good background in compilers. My current masters thesis is aimed at automatic parallel code from c programs target for the Cell Processor using

Am a newbee to Linux and am trying to evaluate various distros to see how they fit my needs. For this purpose I now have six trial Linux partitions on the same machine. My other criterions to replace XP as my main system have been passed by all the distros, but remains the last one: to be able to handle Lotus wk4-files. That is where I have my history. First tried installing Lotus 123 from

Hi, I have run into the following strange behavior and wanted to ask for some advice. For the C program below, function sum() gets inlined in foo() but the code generated looks very suboptimal (the code is an extract from a larger program). Below I show the 32-bit x86 assembly as produced by the demo page on the llvm home page ("Output A"). As you can see from the assembly, after

Dear Pals I think all of us in this business (or most) looking at the Corn Flakes Back Side , Wish to find a NAT Friendly VOIP solution. Thats ridiculous I know, but what about this wish list (Personal Point of view) Upnp support for Asterisk STUN Support for Asterisk Small Embedded Asterisk (just to redirect IAX) SIP-IAX , h.323-IAX or something like that , on the End Point. As a Nat

I don't know much about this, but maybe -mllvm -unroll-count=1 can be used as a workaround? /Patrik Hägglund -----Original Message----- From: llvmdev-bounces at cs.uiuc.edu [mailto:llvmdev-bounces at cs.uiuc.edu] On Behalf Of Brent Walker Sent: den 28 mars 2012 03:18 To: llvmdev Subject: [LLVMdev] Suboptimal code due to excessive spilling Hi, I have run into the following strange behavior

I was trying to simply test bandwidth that Solaris/ZFS (Nevada b63) can deliver from a drive, and doing this: dd if=(raw disk) of=/dev/null gives me around 80MB/s, while dd if=(file on ZFS) of=/dev/null gives me only 35MB/s!?. I am getting basically the same result whether it is single zfs drive, mirror or a stripe (I am testing with two Seagate 7200.10 320G drives hanging off the same interface
