Neither llvm-gcc nor clang support exceptions on ARM (except, maybe, sjlj excheptions on arm/darwin). I have some patched uncommitted for EH on ARM but they are too far from being complete. -- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg State University

Hi, I was comparing the way LLVM generates the exception table and it looks a bit different from what GCC (arm-none-eabi-g++) generates. Maybe that's because clang is not generating ARM IR when I do: $ clang -c -emit-llvm -march=arm -mcpu=cortex-a8 -mtriple=arm-none-eabi exception.cpp -o exception.clang.bc clang: warning: argument unused during compilation: '-mcpu=cortex-a8' clang:

I did some experiments and managed to understand how LLVM does the exception handling, but my changes are also far from working. My ma...
