llvm-svn: 1976
 2002-03-24 03:54:03 +00:00
Vikram S. Adve 479126b3d3 Use deterministic iterator for SchedGraphs. This is actually not 
useful right now when we only do local scheduling.

 2002-03-24 03:53:03 +00:00
Vikram S. Adve 9db158f568 Bug fix: nextToTry was not being initialized in one case.

 2002-03-24 03:45:35 +00:00
Vikram S. Adve c228f7a077 Add option to disable scheduling. 
Destroy live-variable information after scheduling so it is
recomputed before later phases (e.g., reg. allocation).
Use deterministic iterator to enumerate sched graphs.

Also, add a flag to marked nodes that do not need code because they
have been folded into the user (parent in the BURG tree).

Chris Lattner 70b130f27b Testcase for a missed level raise opportunity 
llvm-svn: 1932
 2002-03-21 21:20:04 +00:00
Chris Lattner 06707765fa Make ConvertableToGEP handle cases where the user is indexing into the 
first element of a structure type.  Before this would not be handled because
getStructOffset would either stop immediately (because StopEarly was true
and Offset = 0), or blast past the level we wanted.

Now ConvertableToGEP steps down through the type one level at a time, checking
the Offset and Scale conditions at each step

Chris Lattner 0d984ef719 Fix the: test/Regression/Other/2002-03-20-LevelRaiseCrash.ll bug. It turned 
out that almost always the result of the add was the same as the GEP that
would be generated.  In this case, however, it wasn't, so bad things happened.
