Hi All,
Based on below links __ubsan_handle_type_mismatch has been renamed to __ubsan_handle_type_mismatch_v1.
https://github.com/llvm-mirror/compiler-rt/commit/56faee71af1888ba12ab076b3d1f9bbe223493df#diff-21369cc6f3917b27df3ced8de89cf134 https://www.mail-archive.com/gcc-bugs@gcc.gnu.org/msg535130.html
When I tried to compile the kernel with LLVM seen following errors. arch/arm64/kernel/traps.o: In function `dump_backtrace': kernel/arch/arm64/kernel/traps.c:192: undefined reference to `__ubsan_handle_type_mismatch_v1' kernel/arch/arm64/kernel/traps.c:192: undefined reference to `__ubsan_handle_type_mismatch_v1' kernel/arch/arm64/kernel/traps.c:192: undefined reference to `__ubsan_handle_type_mismatch_v1' kernel/arch/arm64/kernel/traps.c:192: undefined reference to `__ubsan_handle_type_mismatch_v1' arch/arm64/kernel/traps.o: In function `dump_mem':
Can I add __ubsan_handle_type_mismatch_v1 API similar to __ubsan_handle_type_mismatch()(I will send path for review)? If both apis are present, then there will be backward compatibility. Let me know if you have any other suggestions for this issue.
-Thanks, Prasad
