Hi all, I'm getting more impressed by LLVM day by day, but what's a bit unclear to me now is the order of optimization passes, and their performance. I think I have a pretty solid understanding of what each pass does at a high level, but I couldn't find any documentation about how they interact at a lower level. I'd like to use LLVM for generating high-performance stream

Hi all! I'm thinking on installing OGO on CentOS 4. I've been to download.opengroupware.org but I didn't find any CentOS/RHEL 4 specific rpm packages. I'm wondering, since RHEL4/CentOS4 is based on Fedora Core 3, can I use these packages safely? Has anyone ever tried installing OGO on CentOS 4? Has anyone ever used ogoall-...rpm ? Thankx in advance. Best regards, Pedro

Hi Chris, Thanks for the detailed explanations. I have a few remaining questions: Am I correct that ScalarReplAggregates is hardly more expensive than Mem2Reg and therefore generally preferable? What would be the code quality implications of using "-dce -simplifycfg" instead of -adce? As far as I understand the algorithms involved, -dce would hardly ever miss a dead instruction if

ProxyDHCP can be very selective about only providing a response to previously known clients, implementation-dependent, supersceding DHCP responses for boot data while the client system uses the DHCP server for its address data. It's commonly accepted that the PXE spec reversed priority. >> as a solution, I seek a simple USB-based shim that >> will boot locally and then chain me over to my PXE server. Attempts...

Question: If syslinux.efi is loaded locally off USB rather than via an EFI PXE option ROM boot, but on a client whose EFI firmware has TCP support, should that locally-booted syslinux.efi be able to process HTTP URLs? Initial experiments indicate "no", but why not? Purpose: My TCP-capable EFI client is on a subnetwork with broken DHCP not under my control, so I can't

How do I get the necessary binutils on Windoze? Install MinGW or
