[cfe-dev] [LLVMdev] ARM EABI Exceptions

[Duncan Sands]

Hi Renato,

> Up until __cxa_throw, everything is fine. The parameters are the same, in the same registers and the table header is similar. The failures come when getting into __cxa_begin_catch, when the PR recognizes the type thrown ('int') but still calls terminate. I'm guessing the action table is different, but there is no documentation on neither LLVM nor GCC intrinsics I could find.

if you compile with -fverbose-asm you should get some helpful comments in the
action table.  You could also send the tables to the mailing list.

> Does LLVM have implementations of __cxa_* intrinsics? If so, where are they?

These aren't intrinsics, they are C++ standard library functions.

Ciao,

Duncan.
