idk what godbolt is, but if it's some sort of online compiler, then I
suppose it's of limited usefulness for the Linux kernel.

Easiest way to see a disassembly (also has C code interleaved) would be
this:

make drivers/net/dsa/microchip/ksz_ethtool.lst

This is also useful to see precisely which instruction went boom in case
there's a NULL pointer dereference or something like that.
