Hi all, I have a custom alias analysis pass that enforces that pointers from different address spaces do not alias, and I'm using MemoryDependenceAnalysis to, well, figure out dependence analysis. The AA pass is extremely simple, it only checks the address space of pointers, returns NoAlias if they're different, and delegates otherwise. It is the last alias analysis pass added to my

...ink that the personality-specific unwind tables were actually an ABI "artifact". I mean, let's say you compile a function in Visual Studio, the result is a function with some mangled symbol that other object code can make references through the linker. But the other object code never incestuously refers to the unwind tables of the function it calls, right? I'm speaking from the point of view of an implementor of a new programming language who wants to interoperate with C++. I've already got code that can decode the Microsoft RTTI info coming from C++ exceptions, and the pointe...

Hi folks, is anybody using those two products together and can give me any advice on how to do this? My specific issue has been addressed in other posts before, but as nobody responded, it would just now be interesting if anybody at least uses those applications together successfully? greets Malte

After a long tale of sorrow and woe, my colleagues and I stand here before you defeated. The Itanium EH representation is not amenable to implementing MSVC-compatible exceptions. We need a new representation that preserves information about how try-catch blocks are nested.
