sdardis added a comment. Sorry for the delay in getting back to this, but testing this by building it explicitly for N32 (I built a full N32 compiler + libunwind and modified the test setup py to compile for N322) and I'm getting crashes on the return path in _Unwind_Backtrace.
The problem occurs when saving the registers, as saving the (second I believe) last register clobbers the saved return address. I've seen crashes on MIPS64 (eb). Qemu however is aborting at runtime, but I haven't had the time to trace the execution, and I haven't found a way yet to dump the locations of the shared libraries at runtime to determine where the fault lies. This was with GCC 4.9.2 (debian) on MIPS64 and our 2016.05-06 toolchain for qemu. https://reviews.llvm.org/D39074 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org http://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
