search for: __cxa_eh_globals

I'm at the stage where I'd like to try implementing exception handling for my little language. First off, I had a lot of difficulty understanding the documentation on exception handling until I went and started looking at the source code for libstdc++, in particular the definitions of __cxa_eh_globals and the functions that use it. I did not realize, until reading that code, that the exception pointer is stored using thread-local data. It seems to me that it ought to be possible to write a "pure" LLVM exception implementation that does not depend on the C++ libraries, however I...

+glider The compiler hardly matters here, I would expect the same failures with clang. Alex, could you please take a look? --kcc On Thu, Nov 29, 2012 at 9:55 PM, Jack Howarth <howarth at bromo.med.uc.edu>wrote: > Nick, > Can you take a quick look at the asan_eh_bug.tar.bz testcase > I uploaded into the newly opened radr://12777299, "potential > pthread/eh bug exposed

Nick, Can you take a quick look at the asan_eh_bug.tar.bz testcase I uploaded into the newly opened radr://12777299, "potential pthread/eh bug exposed by libsanitizer". The FSF gcc developers have ported llvm.org's asan code into FSF gcc (and are keeping it synced to the upstream llvm.org code). I have been helping with the darwin build and testing -fsanitize=address against the
