* Use the new script to sort the includes of every file under lib.Chandler Carruth2012-12-03
| | | | | | | | | | | | | | | | | Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8
* Change default error_code ctor to a 'named ctor' so it's more self-documenting.David Blaikie2012-02-09
| | | | | | | | | | | Unify default construction of error_code uses on this idiom so that users don't feel compelled to make static globals for naming convenience. (unfortunately I couldn't make the original ctor private as some APIs don't return their result, instead using an out parameter (that makes sense to default construct) - which is a bit of a pity. I did, however, find/fix some cases of unnecessary default construction of error_code before I hit the unfixable cases) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150197 91177308-0d34-0410-b5e6-96231b3b80d8

* Change the MemoryBuffer::getFile* methods to take just a pointer to theChris Lattner2008-04-01

* For PR797:Reid Spencer2006-08-22
| | | | | | | | | | | Adjust users of MappedFile to its new non-throwing interface. Note that in most cases the lazy step of just throwing after a call to MappedFile was installed. This was done in the name of incremental changes. Getting rid of the new throw statements will take adjustment of interfaces and propagation of errors to higher levels. Those changes will come in subsequent patches. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@29817 91177308-0d34-0410-b5e6-96231b3b80d8
* Change Path::getStatusInfo to return a boolean and error string on an errorChris Lattner2006-07-28

* Adjust DiffFilesWithTolerance to help poor cygwin's mmap facility byReid Spencer2005-02-15

If only one of the files is zero length then we return 1 (false) indicating that the files differ.
