I'm using LLVM to instrument C code to test the efectiveness of some methods of error detection with dynamic invariants (see http:// citeseer.ist.psu.edu/hangal02tracking.html). I'm using also a range invariant (max an min values seen). The problem is that for those invariants, I need to know if the value is signed or not (0xFF can be -1 or 255, depending on signed/unsigned).

The problem is that what i'm instrumenting is loads and stores, plus function call arguments and return values, which have no signedness information.

Hello everyone! I'm using llvm for instrumenting code, and I need to know if there's a way to difference between signed and unsigned Values of integer type during an optimization pass. I know in llvm 1 it was possible, but i'd like to work with llvm 2. Maybe using the debugging information? Is it available during an optimization pass? How do I access it? Thanks in advance Alberto

Hello, I want request to community collaboration to test xenwebmanager before release a beta version. Idea is found bugs and features not working to fix before beta version. For test this version you only need download from: https://sourceforge.net/projects/xenwebmanager/files/xenwebmanager_rev69_full.tar.gz/download uncompress: tar xvfz xenwebmanager_rev69_full.tar.gz and run: cd

I am getting problems with 'make check' on Linux x86. Several instances of 'couldn't execute "-emit-llvm": no such file or directory' :- FAIL: /usr/src/llvm/test/CodeGen/CBackend/2007-01-06-Signless.c Failed with posix(ENOENT,no such file or directory) at line 1 while running: -emit-llvm -S /usr/src/llvm/test/CodeGen/CBackend/2007-01-06-Signless.c -o -

Hi I currently would like to find out the signedness of a instruction. But looking at the CBackend, it looks as if it is not that simple? So i have two questions: Is there an easier way than guessing as it is done in the CBackend? Is there a reason for that signedness is not part of the instruction type? Best regards ST

Hello everybody, I have tried several iptables versions (from 1.2.4 to 1.2.6a) to mark outgoing packets (change the DSCP field) with no success. #iptables -A OUTPUT -t mangle -d 10.0.0.3 -j DSCP --set-dscp 0x2 iptables v1.2.6a: unknown arg ''--set-dscp'' TOS target is working fine, but I want to create different codes for EF and AF classes in a diffserv

Hi, my target handles operands of multiplying instructions differently based on signedness. I wonder then how I would do instruction selection based on the operands signs? The mul instruction sets a nsw for signed, but when i try unsigned ops, there is no wrap flag at all. I'm not sure this is enough information to work with, or?

Buen día para todos. Quisiera saber si conocen de alguna libreria que implemente los métods "forward" en R, al estilo SAS. Agradezco cualquier ayuda -- Luis Alberto López González [[alternative HTML version deleted]]

Buenas tardes. Quisiera saber como puedo aplicar las reglas de un kmeans a otra base, para hacer un proceso de validaciòn de la segmentaciòn. En SAS, se cuenta con el argumento "OUTSEED", ¿què debo tener en cuenta en R? Mil gracias. -- Luis Alberto López González [[alternative HTML version deleted]]

Hi Jonas, > my target handles operands of multiplying instructions differently based on > signedness. since the result of a multiply doesn't depend on the signedness, I find it strange that your target differentiates between them. What I'm saying is that if you have (say) two i32 numbers a and b and you do a signed multiply: c = a *s b and an unsigned multiply d = a *u b
