Hi, I didn't do any serious benchmarking but so far I never found a case where LLVM does better than IAR on CortexM0, but I saw a lot of cases where IAR output is better than LLVM... That said I did not use -Os or -Oz, I just used -O3. A recurrent situation is that LLVM push/pop one or two extra registers compared to IAR, I guess it does so in order to comply with a standard ABI or something but i...

I gave the following function to IAR compiler (targeting CortexM0) and to clang/LLVM 3.2 (clang -O3 -target thumbv6-eabi -emit-llvm) int calleeSave8(int in[]){ int out=0; int i; for(i=0;i<8;i++){ out ^= in[i] & in[(i+1)%8]; }//expand to out = (in[0]&in[1])^(in[1]&in[2])^(in[2]&in[3])^(in[3]&in[4])^(in[4]&...

Hai, This is amar. I have a situation like installing IAR compiler on Fedora 8 so i installed compiler with the help of wine 1.2. It successfully installed :) but i got a problem during build the programs it is asking the Dongle key(USB) Drivers.This Dongle key is Licensed key provided by IAR vendor. These Drivers are not installed during Installation pr...

...and. Anyway this should be a target independent optimization isn't it ??

Hi all, I mounted by smbmount a partition on a winNT machine without problem... but when i tried to copy a file whitch have size more than 2 Gb i have the following error : Overflow size allowed for a file (translated from french ;-) :D?bordement de la taille permise pour un fichier ) PS. the file system of the harde drive is NTFS PS. The command of smbmount : /usr/sbin/smbmount

Hello, I am running a samba 3.0.32 under fedora core 9. I only try to authenticate users against a ldap server. Of course this server knows the encrypted password as microsoft does. I entered the ldap password using smbpasswd to query into the ldap. After this, I just obtain a message like "you don't have rights to ...". What errors do I make ??? Any ideas will be appreciated

Anybody know a tool to migrate smbpasswd to Ldap Backend, i trying using the pdbedit -i smbpasswd:/passwd -e ldapsam:ldap://127.0.0.1, but this don't works. Thanks in advance. Reggards, ---------------------------------- iarly Selbir ( Ski0s )

Hi, this is kind of a strange situation. I have a share that I want to work like a drop box. I want users to be able to create new files and read existing files, but not be able to delete them (except for the owner of the dropbox). Does anyone know how to do this? I've tried every combination I could think of write list, read only, force group, and sticky bits on the directory itself.

In fact, on my shelf is running speex using Raisonance Primer2 DK and IAR STM32-SK DK. But I want to save the power consumption of the device runnig speex, and EFM32 seems to be a very good candidate. Also, do yo think that the STM32F103 (Cortex M3 90 MIPS) could be used to run Speex at 4 Kbps in real time? Regards, Nicolas 2010/3/3 Jean-Marc Valin <jean-marc.valin...

Hi all, I'm rappedly moving away from windows, but one of the last programs i need to run in windows is 'IAR Embedded Workbench (Kickstart Version)' I've tried to run it some time ago (i think about 2 months back) in wine, but it didn't work so well back then. I haven't tried it with newer versions since then. I need that program so i can program my msp430 microcontroller. If anybody...

...ould not be a load from x. Anyway, I'm curious: is the C-like interpretation of a volatile expression statement considered to be a feature by the LLVM maintainers? If so, what is the rationale? I haven't done extensive testing, but there do exist compiler families (such as those from IAR and Intel) where the C compiler loads from x and the C++ compiler does not. [I just sent a very message very much like this one to the GCC mailing list.] Thanks, John Regehr

Hello, I'm sorry if this is not the correct place to ask this question but what I'm looking for is any data on the reality of Speex working on an ARM7 core? I'm looking at doing a few diffrent projects where I will be using a proc such as the LPC2378 with the ARM7TDMI-S core running at 72Mhz (although errata show only 60Mhz is currenlty possible). Do you know if there is a port

I've followed the OpenLDAP + SAMBA Domain Controller tutorial step-by-step: http://ubuntuforums.org/showthread.php?t=640760 And after long hours, and enless googling, I've yet to find a solution. LDAP works great SAMBA works great. But the intergration between them don't work. Here is the samba log: root:/etc# tail /var/log/samba/log.smbd smbd version 3.0.28a started. Copyright
