2007-02-05Apply the VISIBILITY_HIDDEN field to the remaining anonymous classes inReid Spencer
the Transforms library. This reduces debug library size by 132 KB, debug binary size by 376 KB, and reduces link time for llvm tools slightly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33939 91177308-0d34-0410-b5e6-96231b3b80d8
2007-01-26Inherit CallGraphSCCPass directly from Pass.Devang Patel
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@33514 91177308-0d34-0410-b5e6-96231b3b80d8
2006-12-31For PR950:Reid Spencer
This patch replaces signed integer types with signless ones: 1. [US]Byte -> Int8 2. [U]Short -> Int16 3. [U]Int -> Int32 4. [U]Long -> Int64. 5. Removal of isSigned, isUnsigned, getSignedVersion, getUnsignedVersion and other methods related to signedness. In a few places this warranted identifying the signedness information from other sources. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32785 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31924 91177308-0d34-0410-b5e6-96231b3b80d8
2006-11-02For PR786:Reid Spencer
Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting fall out by removing unused variables. Remaining warnings have to do with unused functions (I didn't want to delete code without review) and unused variables in generated code. Maintainers should clean up the remaining issues when they see them. All changes pass DejaGnu tests and Olden. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31380 91177308-0d34-0410-b5e6-96231b3b80d8
2006-10-20For PR950:Reid Spencer
This patch implements the first increment for the Signless Types feature. All changes pertain to removing the ConstantSInt and ConstantUInt classes in favor of just using ConstantInt. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31063 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

2004-11-13Argument promotion transforms functions to unconditionally load theirChris Lattner
argument pointers. This is only valid to do if the function already unconditionally loaded an argument or if the pointer passed in is known to be valid. Make sure to do the required checks. This fixed ArgumentPromotion/control-flow.ll and the Burg program. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17718 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

2004-09-18Convert this pass to be a CallGraphSCCPass instead of a Pass, which eliminatesChris Lattner
the worklist and makes it more efficient. This does not change functionality at all. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16390 91177308-0d34-0410-b5e6-96231b3b80d8

2004-06-21Make order of argument addition deterministic. In particular, the layoutChris Lattner
of ConstantInt objects in memory used to determine which order arguments were added in in some cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@14276 91177308-0d34-0410-b5e6-96231b3b80d8
2004-05-23Fairly substantial changes to update the alias analysis we are querying asChris Lattner
we make the transformation. This allows us to use interprocedural alias analyses successfully. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@13691 91177308-0d34-0410-b5e6-96231b3b80d8
2004-03-08Implement ArgumentPromotion/aggregate-promote.llChris Lattner
This allows pointers to aggregate objects, whose elements are only read, to be promoted and passed in by element instead of by reference. This can enable a LOT of subsequent optimizations in the caller function. It's worth pointing out that this stuff happens a LOT of C++ programs, because objects in templates are generally passed around by reference. When these templates are instantiated on small aggregate or scalar types, however, it is more efficient to pass them in by value than by reference. This transformation triggers most on C++ codes (e.g. 334 times on eon), but does happen on C codes as well. For example, on mesa it triggers 72 times, and on gcc it triggers 35 times. this is amazingly good considering that we are using 'basicaa' so far. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@12202 91177308-0d34-0410-b5e6-96231b3b80d8
