Devang Patel fdee7034b3 The pass manager is not able to schedule -loop-deletion -loop-index-split. 
The loop-deletion pass does not preserve dom frontier, which is required by
loop-index-split. When the PM checks dom frontier for loop-index-split, it has
already verified that lcssa is availalble. However, new dom frontier forces new
loop pass manager, which does not  have lcssa yet.

The PM should recheck availability of required analysis passes in such cases.

Devang Patel ec9e1a60ad Keep track of analysis usage information for passes. Avoid invoking 
getAnalysisUsage() repeatedly.

 2008-08-11 21:13:39 +00:00
Chris Lattner 4c493d9a58 Don't call getAnalysisUsage unless -debug-pass is enabled. This speeds 
up the passmgr by avoiding useless work.

Devang Patel ab85d6b6af "Unable to schedule <A> required by <B>" is more helpful then 
"Unable to handle Pass that requires lower level Analysis pass"

Dan Gohman d78c400b5b Clean up the use of static and anonymous namespaces. This turned up

but not intended to be global.

Devang Patel af75ab8130 Do not use virtual function to identify an analysis pass. 
llvm-svn: 48520
 2008-03-19 00:48:41 +00:00
Devang Patel 864970e9b6 Identify Analysis pass. 
Do not run analysis pass again if analysis info is still available.
This fixes PR1441.

 2008-03-13 01:57:34 +00:00
Dan Gohman 73caf5ff10 Change PMTopLevelManager's PassManagers vector element type from 
Pass* to PMDataManager*. PMDataManager is more specific than Pass,
so this more accurately describes the objects that are being stored.

This eliminates the need for several dynamic_casts to PMDataManager*.
It does introduce one dynamic_cast though, in dumpPasses(). Give
this one a comment describing why a dynamic_cast is being used.

 2008-03-13 01:48:32 +00:00
Dan Gohman 11eecd635c Change PMStack::push to accept a PMDataManager* instead of 
a Pass*. PMDataManager* is what it actually holds, so this
makes it clearer.

 2008-03-13 01:21:31 +00:00
Dan Gohman d3a20c9e1e Give PassManager and FunctionPassManager a common base class, with 
add(Pass *) as a pure virtual member function. This will allow all
the various addPassesTo* functions in LLVM to avoid hard-coding what
type of PassManager is used.
