Chris Lattner 21a7218c5f Make sure to add a targetdata instance to the passmanager, and make it match the
one in use by the TargetMachine

Chris Lattner ba90675054 Fix problem where we would read 64 bits worth of pointer information, even on 32 bit targets!

Chris Lattner 3c98276168 Fix major problem with PHI node traversal: rechecking PHIs should go into
the visit function.  The worklist is for when their lattice value changes.

Chris Lattner 0347cda8b8 Rename Kept -> Suffix

Chris Lattner e483398516 Allow for easy detection of when a "default" TargetData is created by the
passmanager, which is never the right thing to do.

Chris Lattner 65e5f653fd Big programs have tons of global variable initializers, and most passes don't care
about them.  Try to delete them if it doesn't affect the passes.

Chris Lattner f32939bbc9 Speed up convergence significantly and also reduce the size of testcases by making large portions of a function's CFG dead at a time.

2003-04-24 23:51:38 +00:00
Chris Lattner de39f2bdac The big fix is this change:
-    if (I->isExternal() && !Functions.count(I))
+    if (!I->isExternal() && !Functions.count(I))

We were not actually deleting any functions from the module!

Chris Lattner 60430423c9 Fix a nasty bug where the ConstantMerge pass was invalidating the TargetData pass
even though it was immutable.  Immutable passes should never end up in CurrentAnalyses!
