2007-05-02Use 'static const char' instead of 'static const int'.Devang Patel
Due to darwin gcc bug, one version of darwin linker coalesces static const int, which defauts PassID based pass identification. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@36652 91177308-0d34-0410-b5e6-96231b3b80d8

2005-03-15This mega patch converts us from using Function::a{iterator|begin|end} toChris Lattner
using Function::arg_{iterator|begin|end}. Likewise Module::g* -> Module::global_*. This patch is contributed by Gabor Greif, thanks! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@20597 91177308-0d34-0410-b5e6-96231b3b80d8
2004-09-20'Pass' should now not be derived from by clients. Instead, they should deriveChris Lattner
from ModulePass. Instead of implementing Pass::run, then should implement ModulePass::runOnModule. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16436 91177308-0d34-0410-b5e6-96231b3b80d8

2003-09-16This is effectively a complete rewrite of the globaldce algorithm, resultingChris Lattner
in it being both shorter and more effective. It no longer depends on the callgraph, so one FIXME has been fixed. Additionally, this pass was not able to delete recursive (but dead) functions if they were pointed to by global variables which were also dead. In fact this pass had a lot of problems deleting functions which were only pointed to by dead globals and other stuff. Fixing this means that the entire EH library should be stripped away now from programs that don't use sjlj or exceptions. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8567 91177308-0d34-0410-b5e6-96231b3b80d8

2003-08-07Fixed a segfault in gccld.John Criswell
The original code does not work because the value from WorkList.end() is invalidated once WorkList.erase() is called. To ensure proper functionality, we must ensure that WorkList.erase() is always called before WorkList.end(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@7673 91177308-0d34-0410-b5e6-96231b3b80d8

2002-10-01Updates to work with recent Statistic's changes:Chris Lattner
* Renamed StatisticReporter.h/cpp to Statistic.h/cpp * Broke constructor to take two const char * arguments instead of one, so that indendation can be taken care of automatically. * Sort the list by pass name when printing * Make sure to print all statistics as a group, instead of randomly when the statistics dtors are called. * Updated ProgrammersManual with new semantics. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@4002 91177308-0d34-0410-b5e6-96231b3b80d8

2002-04-27* Rename MethodPass class to FunctionPassChris Lattner
- Rename runOnMethod to runOnFunction * Transform getAnalysisUsageInfo into getAnalysisUsage - Method is now const - It now takes one AnalysisUsage object to fill in instead of 3 vectors to fill in - Pass's now specify which other passes they _preserve_ not which ones they modify (be conservative!) - A pass can specify that it preserves all analyses (because it never modifies the underlying program) * s/Method/Function/g in other random places as well git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2333 91177308-0d34-0410-b5e6-96231b3b80d8
