https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D234232 Bug ID: 234232 Summary: clang Assertion failed when building the port devel/aws-checksums Product: Base System Version: CURRENT Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: danilo@FreeBSD.org Clang is segfaulting on CURRENT when building devel/aws-checksums. It stops at this assertion: Assertion failed: (i =3D=3D DstIdx || !MI->getOperand(i).isReg() || MI->getOperand(i).getReg() !=3D RegA), function processTiedPairs, file /usr/src/contrib/llvm/lib/CodeGen/TwoAddressInstructionPass.cpp, line 1544. TwoAddressInstructionPass.cpp:1544. #ifndef NDEBUG // First, verify that we don't have a use of "a" in the instruction // (a =3D b + a for example) because our transformation will not // work. This should never occur because we are in SSA form. for (unsigned i =3D 0; i !=3D MI->getNumOperands(); ++i) assert(i =3D=3D DstIdx || !MI->getOperand(i).isReg() || MI->getOperand(i).getReg() !=3D RegA); #endif The target file (source/intel/crc32c_sse42_asm.c) has a lot of assembly inl= ine code. --=20 You are receiving this mail because: You are the assignee for the bug.=
