In original GNU libgcc, _Unwind_Backtrace is published with GCC_3.3 vers= ion for all architectures but ARM. For ARM should be publishes with GCC_4.3.0 version. This was originally omitted in r255095, fixed in r318024 and omi= tted aging in LLVM libunwind implementation in r354347. For ARM _Unwind_Backtrace should be published as default with GCC_4.3.0 version , (because this is right original version) and again as normal(not-default) with GCC_3.3 version (to maintain ABI compatibility compiled/linked with wrong pre r318024 libgcc) PR: 233664 Changes: =20 projects/clang1100-import/contrib/llvm-project/libunwind/src/UnwindLevel1-g= cc-ext.c --=20 You are receiving this mail because: You are on the CC list for the bug.=
