I suggest you turn the scalars into arrays and make the ptr argument volatile as well. Other ways: If you are careful with tail recursion eliminiation, you can compare local var addresses from different recursive calls. I believe there are va_arg based approaches as well. That said, there is no truly portable way. /Stein Roger

...l get rid of one of the loads and insert an inttoptr/ptrtoint. This is incorrect (in our memory model, at least), since GVN is essentially introducing implicit casts with the memory operations. One of the consequences of memory models that support implicit casts is that they make dead store eliminiation illegal in general, which is not really desirable (more details in the paper draft I sent you). >> My personal opinion is that we should fix LLVM/clang such that memory >> operations are properly typed.

Hello all, Some may find this redundant, but this addresses a lot of qustions that I've been seeing, in the last few months, that were not dealt with, in the whole. In this message, I am addressing only capabilities, not specific HOW-TOs. It's more of a WHAT-IT-CAN-DO with a hint of WHY-YOU-WOULD-WANT-TO. In the near view, treat this as a features test report. SUMMARY: The questions were

Thanks very much. I only have one more question, (hopefully), which is, is there a better way of finding the direction of stack growth other than: static bool StackCmp(void *ptr) { volatile int a; return (void *)&a > ptr; } bool FindStackDirection() { volatile int a; return StackCmp((void *)&a); } Preferably one which isn't destroyed by optimization. Thanks again,

Hola a todos, Os escribía para saber si alguno conocéis alguna herramienta tipo SonarQube, para medir la calidad del software desarrollado en R.

Sorry for the unnecessary list mail. No problem, this is a better way to go. The MallocInst and FreeInst instructions are about to be removed from LLVM IR.

Any opinions on the best ATA? For example, if someone was having a problem and I wanted to rule out any ATA glitches or firmware issues, what device could I give them that I could count on to always be a trouble free top performer that just plain works?

I blogged about some of the problems with aaf in production (http://www.jroller.com/BrightCandle) yesterday but inspired by the poitive response I thought I would share the perceived problems and discuss some of the potential solutions to help newcomers and make aaf work as if by magic just like Rails does. All of these problems boil down to one simple problem, running acts as ferret in a
