This commit fixes the unw_step() for ARM EHABI. However, this commit also changes the implementation details for ARM EHABI. The first change is that the personality function should call __gnu_unwind_frame() for default (or de facto) frame unwinding based on the ARM-defined unwind opcode. The function __gnu_unwind_frame() will in turn calls unw_step() which actually unwinds the frame. The second change is that the implementation _Unwind_Backtrace() should no longer calls unw_step() to unwind the frame; since according to ARM EHABI, the personality function should unwind the frame for us. Special thanks to Anton for helpful suggestion on the initial version of this patch. llvm-svn: 238560 |
