In my case, I am working on a posix regular expression library that uses LLVM to execute a regular expression. Each regular expression is a very small sets of code and is faster to interpret than to JIT then execute. I wanted to JIT only when the regular expression is executed more than 20 times. The benchmarks I have run show that my library is amzingly fast to execute a regular expression

Hi Salomon, please don't forget to reply to the list too (I've CC'd the list). > I don't think my code is doing anything worng... No, it looks fine to me, and the interpreter certainly supports this. That suggests that the value of %str is not being transmitted to the function right. If it is getting the wrong pointer value, that would explain why it barfs. Ciao, Duncan.

You need a pointer-to-function type, but FunctionType just gives you a function type. Use PointerType::getUnqual(FunctionType::get(...)). Or TypeBuilder<char (*func)(void*), false>::get(context) from Support/TypeBuilder.h.

Hi all. I would like to declare a function that takes a function pointer as an argument. In C, it would be : void execute(char (*func)(void*), void *param) So, in my compiler, I have : std::vector<const Type *> cbFPtrArgs(1, Type::getInt8PtrTy(C)); FunctionType * cbFPtrTy = FunctionType::get(Type::getInt8Ty(C), cbFPtrArgs, false); Function * func =

Hello, Anyone else experiencing problems with the latest spandsp (pre3) and last libtiff beta? I'm getting 8 bytes long file, with the TIFF header only during such connection: -- Accepting call from 'XXXXXXX' to 'YYYYYY' on channel 0/2, span 1 -- Executing SetVar("Zap/2-1", "FAXFILE=/tmp/foch.tif") in new stack -- Executing

I am using Service Pack 5 on Windows NT Terminal Server 4.0. I understand that there may be an issue with SP5, but I am unable to upgrade immediately. Is there a registry entry on the NT server I can use? I cannot find anything on your web site but will continue looking.

Hi everyody, ince some of you asked for references, here some links: A good book is 'Data Compression' from David Salomon, ISBN 0-387-98280-9.

Hello R-users, I have been trying to fit what I think is a simple mixed-effects model using lmer (from lme4), but I've run into some difficulty that I have not been able to resolve using the existing archives or Pinheiro and Bates (2000). I am measuring populations (of birds) which change with time at a number of different sites. These sites are grouped into regions. Sites are not measured

Hi all, I have setup samba / openldap as describes by the idealx howto and as such I am using the smbldap-tools. However, I would like to add the givenname and email address fields for all users. What is the best way to do this? I would prefer continuing to use the smbldap-tools, but I cannot seem to find a good way to do this. When I try to: $ smbldap-usermod -M testuser@testdomain.net

Hi all! I have configured a Samba PDC (3.0.7) on a Fedora Core 2 machine with LDAP authentication (conform http://samba.idealx.org/smbldap-howto.en.html). I have about 180 Windows XP Pro clients using this PDC to log onto the domain, which works great! However I seem to have trouble synchronizing the time on the clients to the time on the server. The users (in group Domain Users) do not have

Hi all, I'm trying to get rsync running on a Windows 2k box (my tape backup server) to remotely back up stuff from a few unix boxes. Not my favored constellation, but there's not much I can do about that. I'm hoping someone could give me a quick tip or two on getting rsync working as a Win2k service. I'm not real proficient with Win2k, so be gentle. The posts I could find

I have just spent a day trying to determine why I seemed to be unable to read a file of microarray expression results into R properly. The file was produced by the Dchip software developed by Li and Wong at Harvard's Department of Biostatistics. It contains rows of tab-delimited fields in the order Probe set identifier Probe set description Array 1 expression Array 1 call Array 2 expression

Hi, OLPC's Openfirmware (OFW) implementation chokes when attempting to boot an iso created by isohybrid. The problem is that OFW's ISO-9660 support expects a partition type of 0x96 (CHRP ISO-9660, according to http://en.wikipedia.org/wiki/Partition_type). I see from

Hi, Can anyone tell me what the 'client_workarounds = outlook-idle' directive exactly does? I have enabled it in my /etc/dovecot.conf, but the problem that I think it should solve still exsits. That is that after being IDLE for more than half an hour Dovecot will disconnect Outlook but Outlook never connects back. Therefore users receive new mail, but they don't get notified unless

Hi Timo, I am sorry to bug you about this, but I am a bit confused and I have approx 200 users so I don't want to screw this up. I am using the latest FC2 Dovecot RPM: dovecot-0.99.10.5-0.FC2. I am using NFS to mount the /home dirs on the fileserver from the mailserver with mbox. In the docs you said that I should probably use :INDEX=MEMORY. However I think this really pushes the server to
