* For PR495:Reid Spencer2005-07-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | Get rid of the difference between file paths and directory paths. The Path class now simply stores a path that can refer to either a file or a directory. This required various changes in the implementation and interface of the class with the corresponding impact to its users. Doxygen comments were also updated to reflect these changes. Interface changes are: appendDirectory -> appendComponent appendFile -> appendComponent elideDirectory -> eraseComponent elideFile -> eraseComponent elideSuffix -> eraseSuffix renameFile -> rename setDirectory -> set setFile -> set Changes pass Dejagnu and llvm-test/SingleSource tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22349 91177308-0d34-0410-b5e6-96231b3b80d8

* Take advantage of the fact that we are allowed to clobber the input moduleChris Lattner2004-11-161-26/+8
| | | | | | | | | | | | | | | by splicing function bodies from the src module to the destination module. This speeds up linking quite a bit, e.g. gccld time on 176.gcc from 26s -> 20s when forming the .rbc file, with a profile build. One of the really strange but cool effects of this patch is that it speeds up the optimizers as well, from 12s -> 10.7s, presumably because of better locality??? In any case, this is just a first step. We can trivially get rid of the LocalMap now and do other simplifications. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@17893 91177308-0d34-0410-b5e6-96231b3b80d8
