Sorry, it's __aeabi_d2uiz of course. contrib/llvm-project/compiler-rt/lib/builtins/fixunsdfsi.c:
COMPILER_RT_ABI su_int __fixunsdfsi(fp_t a) { return __fixuint(a); }
#if defined(__ARM_EABI__)
#if defined(COMPILER_RT_ARMHF_TARGET)
AEABI_RTABI su_int __aeabi_d2uiz(fp_t a) { return __fixunsdfsi(a); }
#else
COMPILER_RT_ALIAS(__fixunsdfsi, __aeabi_d2uiz)
#endif
#endif
Presumably making this available is just a matter of #defines and Symbol.map entries.

When compiling the following code in Thumb mode on armv6 FreeBSD 13, linking fails due to an undefined symbol __aeabi_d2iz. On armv7 FreeBSD 13 the issue is not directly reproducible because this support function is not needed, but you can pass -march=armv6 to make it fail the same way. #include <stdio.h> #include <stdlib.h> int main() { double f; f = strtod("1.0", NULL); printf("%u\n", (unsigned int)f); } To compile, type: $ cc -mthumb -o x x.c 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.
