Devang Patel 8c78a0bff0 Drop 'const' 
llvm-svn: 36662
 2007-05-03 01:11:54 +00:00
Devang Patel e95c6ad802 Use 'static const char' instead of 'static const int'. 
Due to darwin gcc bug, one version of darwin linker coalesces
static const int, which defauts PassID based pass identification.

llvm-svn: 36652

Devang Patel 01919d2c0b Speed Up Pass Manager. 
- Check Immutableness before searching PreservedSet.
- Avoid unnecessary traversal while setting Last User.

llvm-svn: 34974
 2007-03-06 17:52:53 +00:00
Devang Patel 42dd1e92c7 Keep track of inherited analysis. For example, if a loop pass does not 
preserve dominator info then it should update parent FPPassManager's
available analysis info to reflect this.

llvm-svn: 34942
 2007-03-06 01:55:46 +00:00
Devang Patel d74ede70fb Add preparePassManager() hook. This allows each pass to check whether 
current active pass manager is appropriate or not.

A loop pass may consider current LPPassManager in appropraite if loop
pass is not preserving analysis information that is used by other
passes managed by current LPPassManager. In such situation, loop pass
can pop current LPPassManager from the PMStack using this  hook
and use new LPPassManager for itself.

llvm-svn: 34941
 2007-03-06 01:06:16 +00:00
Devang Patel ec2b9a7850 Current pass manager, not the parent pass manager, assumes the role of 
last user when one of the managed pass uses info provided by parent pass
manager.

This was exposed by LPPassManager work.

Devang Patel 1c3633e461 - Undo previous check-in (i.e. Do not export TimingInfo class through

Devang Patel e3068403bd At the beginning of run, initialize analyis info availability for _ALL_
