| | | | | | | 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. llvm-svn: 33939

* For PR950:Reid Spencer2006-12-311-3/+3
| | | | | | | | | | | | | 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. llvm-svn: 32785
* Eliminate static ctors due to Statistic objectsChris Lattner2006-12-191-7/+4
| | | | llvm-svn: 32693
* Detemplatize the Statistic class. The only type it is instantiated withChris Lattner2006-12-061-3/+3
| | | | | | is 'unsigned'. llvm-svn: 32279
* Replace #include <iostream> with llvm_* streams.Bill Wendling2006-11-261-8/+7
| | | | llvm-svn: 31924
* For PR786:Reid Spencer2006-11-021-2/+0
| | | | | | | | | | 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. llvm-svn: 31380
* For PR950:Reid Spencer2006-10-201-3/+3
| | | | | | | | 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. llvm-svn: 31063

| | | | | | | | using Function::arg_{iterator|begin|end}. Likewise Module::g* -> Module::global_*. This patch is contributed by Gabor Greif, thanks! llvm-svn: 20597

* Argument promotion transforms functions to unconditionally load theirChris Lattner2004-11-131-3/+51
| | | | | | | | | | 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. llvm-svn: 17718
* 'Pass' should now not be derived from by clients. Instead, they should deriveChris Lattner2004-09-201-1/+1
| | | | | | | from ModulePass. Instead of implementing Pass::run, then should implement ModulePass::runOnModule. llvm-svn: 16436

* Convert this pass to be a CallGraphSCCPass instead of a Pass, which eliminatesChris Lattner2004-09-181-39/+33

| | | | llvm-svn: 16384
* Changes For Bug 352Reid Spencer2004-09-011-4/+4
| | | | | | | | Move include/Config and include/Support into include/llvm/Config, include/llvm/ADT and include/llvm/Support. From here on out, all LLVM public header files must be under include/llvm/. llvm-svn: 16137
* bug 122:Reid Spencer2004-07-181-30/+1
| | | | | | - Excise dead CPR procesing. llvm-svn: 14944
* Make order of argument addition deterministic. In particular, the layoutChris Lattner2004-06-211-10/+35
| | | | | | | of ConstantInt objects in memory used to determine which order arguments were added in in some cases. llvm-svn: 14276
* Fairly substantial changes to update the alias analysis we are querying asChris Lattner2004-05-231-39/+92
| | | | | | | we make the transformation. This allows us to use interprocedural alias analyses successfully. llvm-svn: 13691
* Implement ArgumentPromotion/aggregate-promote.llChris Lattner2004-03-081-25/+145
| | | | | | | | | | | | | | | | | | 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. llvm-svn: 12202
