Re: [PATCH] Speed up for_each_rtx


But this is also interesting:

(I'll point out once more that a long time in bootstrap is spent
in ld -- about 8 minutes).


How did you measure this?

This is just a conservative approximation, I used a stopwatch and measured the time spent in the final link for libstdc++ and libjava.


Also consider several minutes pass before stage2 starts running, and that compiling libjava to libgcj.jar does not use for_each_rtx. A better measurement of the speedup would be "make bootstrap2 && time make bootstrap", or something akin to that, but still it would not account for linking.
