Hi Dieter, Sorry my mistake. I wanted to convert them into Decimal (not Hexadecimal). Given this string, the desired answer follows: > ascii_str <- "ORQ>IK" 79 82 81 62 73 75 > ascii_str2 <- "FDC" 70 68 67 - Gundala Viswanath Jakarta - Indonesia On Mon, Dec 22, 2008 at 5:49 PM, Dieter Menne <dieter.menne at menne-biomed.de> wrote: > Gundala Viswanath <gundalav <at> gmail.com> writes: > >> F...

This conversation has (partially) moved on to D37896 now, but if possible I was hoping that we could perform this in DAGCombiner and remove the various target specific combines that we still have. At least ARM/AARCH64 and X86 have cases that can hopefully be generalised and removed, but there will probably be a few legality/perf issues that will occur. Simon. > On 14 Sep 2017, at 06:23,

Dear sir, I have to set up a mail gateway which will be explored to Internet and a secure mail server in the Intranet. I need a smart imap proxy in the mail gateway which will fetch the mail from server and present to user through either a stand alone mail client or a web mail client. All authentication is through ldap server. I have installed Dovecot 2.2 Unstable in my Ubuntu 12.04 with ssl

Hi, This set of patches contains initial kexec/kdump implementation for Xen v2 (previous version were posted to few people by mistake; sorry for that). Currently only dom0 is supported, however, almost all infrustructure required for domU support is ready. Jan Beulich suggested to merge Xen x86 assembler code with baremetal x86 code. This could simplify and reduce a bit size of kernel code.

This is hopefully the last iteration of the pvops64 patch. >From the last version, we have only one change, which is include/asm-x86_64/processor.h: There were still one survivor in raw asm. Also, git screwed me up for some reason, and the 25th patch was missing the new files, paravirt.{c,h}. (although I do remember having git-add'ed it, but who knows...) Andrew, could you please push it
