* For PR495:Reid Spencer2005-07-072-18/+26
| | | | | | | | | | | | | | | | | | | | | | 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

* PR466:Reid Spencer2004-12-021-41/+54
| | | | | | | | | | | | | | | | | * Make the linker find lib*.bca files now instead of lib*.bc since those are what the makefiles now generate for bytecode archives. * Make sure the linker only links archives when LinkLibraries is called. Previously if it found a lib*.bc file and that file was a bytecode file, it would link in the entire bytecode. This could make -lc -lc fail with duplicate symbols error but it shouldn't as searching multiple libraries, even the same one more than once, is permitted. * Now that the above problems are corrected, implement the dependent libs feature. After the module is linked with all specified libraries, the LinkLibraries function will obtain the set of dependent libraries from the linked modules and attemp to find and link against those libraries. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@18428 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
