Change the way that the TD pass inlines graphs.  Instead of inlining each

graph when it visits it.

While we're at it, inline global information from the GG instead of from each
of the callers.  The GG contains a superset of the info that the callers do
anyway, and this way we only need to do it one time (not one for each caller).

on perlbmk, it now takes 36s.  On povray, we went from about 5s to 1.97s.

19 years agoCreate an equivalence class of global variables that DSA will never be able
Chris Lattner [Sat, 19 Mar 2005 22:23:45 +0000 (22:23 +0000)]
Create an equivalence class of global variables that DSA will never be able
to tell apart anyway, and only track the leader for of these equivalence
classes in our graphs.

This dramatically reduces the number of GlobalValue*'s that appear in scalar
maps, which A) reduces memory usage, by eliminating many many scalarmap entries
and B) reduces time for operations that need to execute an operation for each
global in the scalar map.

As an example, this reduces the memory used to analyze 176.gcc from 1GB to
511MB, which (while it's still way too much) is better because it doesn't hit
swap anymore.  On eon, this shrinks the local graphs from 14MB to 6.8MB,
shrinks the bu+td graphs of povray from 50M to 40M, shrinks the TD graphs of
130.li from 8.8M to 3.6M, etc.

This change also speeds up DSA on large programs where this makes a big
difference.  For example, 130.li goes from 1.17s -> 0.56s, 134.perl goes
from 2.14 -> 0.93s, povray goes from 15.63s->7.99s (!!!).

This also apparently either fixes the problem that caused DSA to crash on
perlbmk and gcc, or it hides it, because DSA now works on these.  These
both take entirely too much time in the TD pass (147s for perl, 538s for
gcc, vs 7.67/5.9s in the bu pass for either one), but this is a known
problem that I'll deal with later.
