Can we see some timings with and without this patch?
I'll do some tests with checking disabled once the builds are completed.
Bootstrap times with checking enabled were not affected by the patch, so
was PR8361. The tramp3d testcase showed a significant increase in
compile time, but the 350% performance regression compared to 3.4 is
fixed - in fact, we are now comparing apples-to-apples wrt compile times
of 3.4 and 4.0 for this kind of code (comparisons with leafify show
roughly the same compile time performance regression from 3.4 to 4.0).
I'll post some more exact numbers for a checking disabled compiler later.
