2009-03-06Change various llvm utilities to use PrettyStackTraceProgram inChris Lattner
their main routines. This makes the tools print their argc/argv commands if they crash. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66248 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-06Don't assign rank numbers to debug intrinsic "calls".Dale Johannesen
This is needed so debug info doesn't change codegen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66235 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-06Revert rev. 66167. Devang Patel
We are still not out of woods yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66232 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-06Tweak the check for promotable alloca's to handleDale Johannesen
debug intrinsics correctly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66225 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66224 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66223 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-05GlobalOpt only process non constant local GVs while optimizing global vars.Devang Patel
If non constant local GV named A is used by a constant local GV named B (e.g. llvm.dbg.variable) and B is not used by anyone else then eliminate A as well as B. In other words, debug info should not interfere in removal of unused GV. --This life, and those below, will be ignored-- M test/Transforms/GlobalOpt/2009-03-03-dbg.ll M lib/Transforms/IPO/GlobalOpt.cpp git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66167 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-05Fix another case where debug info was affectingDale Johannesen
codegen. I convinced myself it was OK to skip all pointer bitcasts here too. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66122 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-05Fix another case where a dbg.declare meant somethingDale Johannesen
had 2 uses instead of 1. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66112 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-04Re-commit 65975 and a fix for the problem thatDale Johannesen
was causing llvm-gcc to fail to build. I've verified it bootstraps now; good enough for me. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@66073 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-04Always skip ptr-to-ptr bitcasts when counting,Dale Johannesen
per Chris' suggestion. Slightly faster. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65999 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-04If a global constant is dead then global's debug info should not prevent the ↵Devang Patel
optimizer in deleting the global. And while deleting global, delete global's debug info also. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65994 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-04Make my earlier patch to skip debug intrinsicsDale Johannesen
when counting work; it was only off by 1. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65993 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-03Marking debug info intrinsics as not touching memoryDale Johannesen
caused them to be considered trivially dead. Fix this. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65979 91177308-0d34-0410-b5e6-96231b3b80d8
2009-03-03Instruction counters must skip the bitcasts thatDale Johannesen
feed into llvm.dbg.declare nodes, as well as the debug directives themselves. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65976 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-03When removing a store to an alloca that has only oneDale Johannesen
use, check also for the case where it has two uses, the other being a llvm.dbg.declare. This is needed so debug info doesn't affect codegen. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65970 91177308-0d34-0410-b5e6-96231b3b80d8

2009-03-02If branch conditions' one successor is dominating another non-latch ↵Devang Patel
successor then this loop's iteration space can not be restricted. In this example block bb5 is always executed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@65902 91177308-0d34-0410-b5e6-96231b3b80d8
