I've promised to make more thorough and accurate comparison of
df-branch and mainline on last merge point to the branch. The
df-branch compiler does not include sunday's Steven's patch which uses
a separate obstack for df bitmaps. It does not change code but it can
speedup the df-branch compiler (I'll do compilation time measurement
of the branch with the patch later on this week).
Here the result of how last Steven's patch affects compilation times.
