Chris Lattner 28eeb73f2f If a global is just loaded and restored, realize that it is not changing 
value.  This allows us to turn more globals into constants and eliminate them.
This patch implements GlobalOpt/load-store-global.llx.

Note that this patch speeds up 255.vortex from:

Output/255.vortex.out-cbe.time:program 7.640000
Output/255.vortex.out-llc.time:program 9.810000

to:

Output/255.vortex.out-cbe.time:program 7.250000
Output/255.vortex.out-llc.time:program 9.490000

Which isn't bad at all!

Chris Lattner 78d31c13ff New testcase. Believe it or not, this happens a LOT in vortex

Chris Lattner 46dd5a6304 This optimization makes MANY phi nodes that all have the same incoming value. 
If this happens, detect it early instead of relying on instcombine to notice
it later.  This can be a big speedup, because PHI nodes can have many
incoming values.

llvm-svn: 17741
 2004-11-14 19:29:34 +00:00
Chris Lattner 7515cabe2a Implement instcombine/phi.ll:test6 - pulling operations through PHI nodes. 
This exposes subsequent optimization possiblities and reduces code size.
This triggers 1423 times in spec.

llvm-svn: 17740
 2004-11-14 19:13:23 +00:00
Chris Lattner fd6a717b95 New testcase: the phi can be eliminated if the casts are sucked into it. 
Note that this reduces code size anyway (as well as making further
optimizations simpler) so it's always a win.
