* Drop 'const'Devang Patel2007-05-031-2/+2
| | | | llvm-svn: 36662
* Use 'static const char' instead of 'static const int'.Devang Patel2007-05-021-2/+2
| | | | | | | Due to darwin gcc bug, one version of darwin linker coalesces static const int, which defauts PassID based pass identification. llvm-svn: 36652
* Do not use typeinfo to identify pass in pass manager.Devang Patel2007-05-011-0/+4

| | | | | | LLVM's footprint and speed up linking. llvm-svn: 33941
* Changed llvm_ostream et all to OStream. llvm_cerr, llvm_cout, llvm_null, areBill Wendling2006-12-071-3/+3

* Handle alias sets that have been unified, and thus can have other referencesChris Lattner2006-06-271-3/+3
| | | | | | to them. This fixes a regression in my previous checkin. llvm-svn: 28951
* Don't implement AliasSetTracker::remove in terms of deleteValue. deleteValueChris Lattner2006-06-271-10/+22
| | | | | | | | | causes the pointer to be removed from the underlying alias analysis implementation as well. This impl of remove is also significantly faster than the old one. This fixes: Regression/Transforms/DeadStoreElimination/2006-06-27-AST-Remove.ll llvm-svn: 28950
* Fix a stale pointer issue that caused 300.twolf to fail to build on zionChris Lattner2006-06-261-0/+11
