* fpcmp: Fix bug where fpcmp wouldn't early exit when files obviously differ andDaniel Dunbar2010-06-151-9/+9
| | | | | | no tolerance is set. llvm-svn: 106033
* fpcmp: Fix a possible infinite loop when comparing something like:Daniel Dunbar2010-06-151-0/+8
| | | | | | | | | 1..19 ok to 1..20 o k (yes, the odd space is necessary). llvm-svn: 106032
* Convert some users of ftostr to raw_ostream.Benjamin Kramer2010-01-291-7/+7

* Fix more -Wshorten-64-to-32 warnings.Evan Cheng2008-05-051-2/+4

* Change the MemoryBuffer::getFile* methods to take just a pointer to theChris Lattner2008-04-011-4/+2
| | | | | | | | start of a filename, not a filename+length. All clients can produce a null terminated name, and the system api's require null terminated strings anyway. llvm-svn: 49041
* Change DiffFilesWithTolerance to be written in terms of MemoryBuffer,Chris Lattner2008-04-011-73/+56
| | | | | | | | not an mmapped file. This more closely matches its requirements and provides an implicitly null terminated buffer, something this routine had to emulate itself before. llvm-svn: 49024
* Remove MappedFile support for mapping files for write and execChris Lattner2008-04-011-2/+2
| | | | | | | and shared. This complicates the design, is not used, and probably doesn't even work. llvm-svn: 49022
* Unbreak build with gcc 4.3: provide missed includes and silence most ↵Anton Korobeynikov2008-02-201-0/+1

* Simplify the code and fix a typo.Lauro Ramos Venancio2008-01-281-7/+4

* Fix fpcmp infinite loop when comparing "29-266" with "29-268".Lauro Ramos Venancio2008-01-281-5/+21

* Remove attribution from file headers, per discussion on llvmdev.Chris Lattner2007-12-291-2/+2
| | | | llvm-svn: 45418
* For PR1291:Reid Spencer2007-04-071-2/+2
| | | | | | | Change uses of sys::Path class to sys::PathWithStatus in those places where the file status information is needed. llvm-svn: 35743
* For PR789:Reid Spencer2007-03-291-5/+6
| | | | | | | | Make the sys::Path::getFileStatus function more efficient by having it return a pointer to the FileStatus structure rather than copy it. Adjust uses of the function accordingly. Also, fix some memory issues in sys::Path. llvm-svn: 35476
* For PR789:Reid Spencer2007-03-291-2/+2
| | | | | | Updates for change in interface of getFileStatus method of sys::Path class. llvm-svn: 35458
* Make the absolute/relative tolerance information easier to read/understand.Reid Spencer2006-11-251-2/+3

* Remove redundant <cmath>.Jim Laskey2006-11-081-1/+0

* Beef up the output from DiffFilesWithTolerance by setting the error codeReid Spencer2006-10-181-3/+16
| | | | | | | to describe the difference being reported. This assists with understanding differences an llvm-test and should help with bugpoint too. llvm-svn: 31044
* For PR797:Reid Spencer2006-08-231-83/+75
| | | | | | | Final remove of exception handling from this file. lib/System can no longer throw exceptions so there's no need for try/catch blocks here. llvm-svn: 29848
* For PR797:Reid Spencer2006-08-221-6/+14
| | | | | | | | | | 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. llvm-svn: 29817
* Change Path::getStatusInfo to return a boolean and error string on an errorChris Lattner2006-07-281-12/+16
| | | | | | | | instead of throwing an exception. This reduces the amount of code that is exposed to exceptions (e.g. FileUtilities), though it is clearly only one step along the way. llvm-svn: 29395
* For PR777:Reid Spencer2006-05-151-0/+3
| | | | | | | Add an additional catch block to ensure that this function can't throw any exceptions, even one's we're not expecting. llvm-svn: 28309
* 200.sixtrack prints FP numbers with a very strange notation that uses DChris Lattner2005-08-021-3/+21
| | | | | | | instead of E for exponentials (e.g. 1.234D-43). Add support for this notation. llvm-svn: 22574

* Instead of doing a manual comparison loop, just use memcmp, thanks to JohnCChris Lattner2005-02-151-9/+6
| | | | | | for the suggestion! :) llvm-svn: 20203
* Make this more efficient now that we know both files are the same length.Chris Lattner2005-02-151-2/+2

* Fix spellingMisha Brukman2005-02-151-1/+1
| | | | llvm-svn: 20201
* Adjust DiffFilesWithTolerance to help poor cygwin's mmap facility byReid Spencer2005-02-151-8/+24
| | | | | | | | | | handling zero length files a little more intelligently. If both files are zero length then we return 0 (true) indicating a match. If only one of the files is zero length then we return 1 (false) indicating that the files differ. If the files don't agree in length then they can't match so we skip the first loop that looks for a quick match. llvm-svn: 20200
* Fix crash comparing empty file against nonempty file.Chris Lattner2005-01-231-1/+2
| | | | llvm-svn: 19782

* For PR351:Reid Spencer2004-12-161-7/+0
| | | | | | | | * Remove the "removeFile" function, now implemented by the sys::Path::destroyFile method. * Make the FileRemove work with a sys::Path instead of a std::string llvm-svn: 18999
* For PR351:Reid Spencer2004-12-151-88/+1
| | | | | | | Remove getUniqueFilename and CopyFile. These are now implemented by sys::Path::makeUnique and sys::CopyFile, respectively. llvm-svn: 18946
* For PR351:Reid Spencer2004-12-131-39/+0
| | | | | | | | Remove the MakeFileReadable and MakeFileExecutable functions which are no longer present in LLVM. They have been replaced with the sys::Path methods makeReadable and makeExecutable, respectively. llvm-svn: 18910
* For PR351:Reid Spencer2004-12-131-46/+0
| | | | | | | | The ReadFileIntoAddressSpace and UnmapFileFromAddressSpace functions are no longer used by LLVM. Remove them. Replacement functionality for both functions is now encapsulated in the sys::MappedFile class. llvm-svn: 18903
* For PR351: \Reid Spencer2004-12-131-21/+3
| | | | | | | | The getFileTimestamp and getFileSize functions have been removed from \ FileUtilities.{h,cpp}. They are replaced by Path::getTimestamp and \ Path::getSize,respectively. llvm-svn: 18892
* For PR351:Remove the file type checking methods (now in sys::Path)Reid Spencer2004-12-131-54/+0

* Put in a #error in the event that we don't have an mmap that can map a fileReid Spencer2004-09-201-0/+1
| | | | | | | | into memor. This is just a reminder that the ReadFileIntoAddressSpace function needs to be properly converted to lib/System and implemented via read/write if there's no mmap of file support. llvm-svn: 16428
* Changes For Bug 352Reid Spencer2004-09-011-8/+8
| | | | | | | | 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
