* Remove attribution from file headers, per discussion on llvmdev.Chris Lattner2007-12-291-2/+2

* Integrate the readonly/readnone logic more deeplyDuncan Sands2007-12-011-2/+1
| | | | | | | | | | | | | | | into alias analysis. This meant updating the API which now has versions of the getModRefBehavior, doesNotAccessMemory and onlyReadsMemory methods which take a callsite parameter. These should be used unless the callsite is not known, since in general they can do a better job than the versions that take a function. Also, users should no longer call the version of getModRefBehavior that takes both a function and a callsite. To reduce the chance of misuse it is now protected. llvm-svn: 44487
* Readonly/readnone functions are allowed to throwDuncan Sands2007-11-221-27/+1
| | | | | | | exceptions, so don't turn invokes of them into calls. llvm-svn: 44278
* New CallInst interface to address GLIBCXX_DEBUG errors caused byDavid Greene2007-08-011-1/+1
| | | | | | | | indexing an empty std::vector. Updates to all clients. llvm-svn: 40660

* Drop 'const'Devang Patel2007-05-031-2/+2
| | | | llvm-svn: 36662
* Use 'static const char' instead of 'static const int'.Devang Patel2007-05-021-2/+2
| | | | | | | Due to darwin gcc bug, one version of darwin linker coalesces static const int, which defauts PassID based pass identification. llvm-svn: 36652

* Apply the VISIBILITY_HIDDEN field to the remaining anonymous classes inReid Spencer2007-02-051-1/+2
| | | | | | | 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
* Switch over Transforms/Scalar to use the STATISTIC macro. For each statisticChris Lattner2006-12-191-4/+5
| | | | | | | converted, we lose a static initializer. This also allows GCC to emit warnings about unused statistics. llvm-svn: 32690
* Detemplatize the Statistic class. The only type it is instantiated withChris Lattner2006-12-061-3/+3
| | | | | | is 'unsigned'. llvm-svn: 32279
