            Dave Rigby In general I agree it seems unlikely that gcc 10 alone would cause this slowdown. However, we didn't change any of the compiler-related flags that we pass into Google's GN nightmare, other than one regarding setting an RPATH. The change did switch to using our own binutils and associated tools (that was the whole point of the change), and it's possible that somehow angered the GN configuration in such a way that different compiler flags were passed.
