Hi,

For VS build, the size is same for enable or disable MBEDTLS_NO_UDBL_DIVISION, because the previous code only had GCC build failure. This MACRO doesn't affect the VS build.

For GCC build, the previous code didn`t have the size because of the build failure.
To compare the size ,I add the dummy API for previous code:
tu_int __udivti3 (tu_int a, tu_int b)  { return 0;} And the size has very small change(<1kb) for enable or disable MBEDTLS_NO_UDBL_DIVISION.

Thanks
Wenxing

Hi,
> disabling it can reduce code size in some embedded targets.
Could you provide size change after/before this define enabled?

Thanks,
Yi
