On armv7 FreeBSD 13 the iss= ue is not directly reproducible because this support function is not needed, b= ut you can pass -march=3Darmv6 to make it fail the same way. #include #include int main() { double f; f =3D strtod("1.0", NULL); printf("%u\n", (unsigned int)f); } To compile, type: $ cc -mthumb -o x x.c=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20= =20=20=20=20=20=20=20=20=20=20=20=20=20=20=20=20 ld: error: undefined symbol: __aeabi_d2uiz >>> referenced by x.c >>> /tmp/x-c2541a.o:(main) >>> did you mean: __aeabi_d2iz >>> defined in: /lib/libc.so.7 cc: error: linker command failed with exit code 1 (use -v to see invocation) It appears that this function is missing despite being provided in contrib/llvm-project/compiler-rt/lib/builtins/fixunsdfsi.c. --=20 You are receiving this mail because: You are the assignee for the bug.=
