* Don't use PassInfo* as a type identifier for passes. Instead, use the ↵Owen Anderson2010-08-051-3/+3

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | source addition. Apparently the buildbots were wrong about failures. --- Add some switches helpful for debugging: -print-before=<Pass Name> Dump IR before running pass <Pass Name>. -print-before-all Dump IR before running each pass. -print-after-all Dump IR after running each pass. These are helpful when tracking down a miscompilation. It is easy to get IR dumps and do diffs on them, etc. To make this work well, add a new getPrinterPass API to Pass so that each kind of pass (ModulePass, FunctionPass, etc.) can create a Pass suitable for dumping out the kind of object the Pass works on. llvm-svn: 100249

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | <string> include. For some reason the buildbot choked on this while my builds did not. It's probably due to a difference in system headers. --- Add some switches helpful for debugging: -print-before=<Pass Name> Dump IR before running pass <Pass Name>. -print-before-all Dump IR before running each pass. -print-after-all Dump IR after running each pass.

* Move the dominator verification code out of special code embedded withinDan Gohman2009-09-281-4/+12
| | | | | | | | | | | | the PassManager code into a regular verifyAnalysis method. Also, reorganize loop verification. Make the LoopPass infrastructure call verifyLoop as needed instead of having LoopInfo::verifyAnalysis check every loop in the function after each looop pass. Add a new command-line argument, -verify-loop-info, to enable the expensive full checking. llvm-svn: 82952
* Move this assert to check the condition as soon as it is known.Dan Gohman2009-09-281-1/+1

* Extend the StartPassTimer and StopPassTimer functions so that theDan Gohman2009-09-281-2/+2
| | | | | | | | code that stops the timer doesn't have to search to find the timer object before it stops the timer. This avoids a lock acquisition and a few other things done with the timer running. llvm-svn: 82949

* When a loop is deleted, immediately release all of the activeDan Gohman2009-09-271-0/+9
| | | | | | | | LoopPasses for that loop. This avoids trouble with the PassManager trying to call verifyAnalysis on them, and frees up some memory sooner rather than later. llvm-svn: 82945

* Sprinkle some PrettyStackEntry magic into the passmanager. With this, we nowChris Lattner2009-03-061-5/+7
| | | | | | | | | | | | | | | | get nice and happy stack traces when we crash in an optimizer or codegen. For example, an abort put in UnswitchLoops now looks like this: Stack dump: 0. Program arguments: clang pr3399.c -S -O3 1. <eof> parser at end of file 2. per-module optimization passes 3. Running pass 'CallGraph Pass Manager' on module 'pr3399.c'. 4. Running pass 'Loop Pass Manager' on function '@foo' 5. Running pass 'Unswitch loops' on basic block '%for.inc' Abort llvm-svn: 66260
* Add a method to ScalarEvolution for telling it when a loop has beenDan Gohman2009-02-171-3/+0
| | | | | | | | | | | modified in a way that may effect the trip count calculation. Change IndVars to use this method when it rewrites pointer or floating-point induction variables instead of using a doInitialization method to sneak these changes in before ScalarEvolution has a chance to see the loop. This eliminates the need for LoopPass to depend on ScalarEvolution. llvm-svn: 64810

* Use 'static const char' instead of 'static const int'.Devang Patel2007-05-021-1/+1
| | | | | | | Due to darwin gcc bug, one version of darwin linker coalesces static const int, which defauts PassID based pass identification. llvm-svn: 36652
