* Add some basic Pool-allocation infrastructure. This adds a Recycler class,Dan Gohman2008-07-071-0/+7
| | | | | | | | for handling bookkeeping for deleted objects, as well as the alist class template, for keeping lists of objects allocated from Recyclers, and some related utilities. llvm-svn: 53210
* Add a version of AddString that takes a const char* so we can avoid extraneousOwen Anderson2008-07-011-0/+38

* Append to the ActiveTimers std::vector before looking at the timer insteadDan Gohman2008-06-241-1/+1
| | | | | | | | of after, so that any reallocation it does doesn't get counted for the pass being timed. This probably doesn't account for a timing discrepancy I was looking into, but I'm fixing it anyway. llvm-svn: 52693
* First step to fix PR2088. Implement routine to compute the Wojciech Matyjewicz2008-06-231-7/+48

* As comments said, for negative value, the arithmetic Zhou Sheng2008-06-051-1/+1

* Fix compilation errors on MSVC. Patch by Argiris Kirtzidis!Bill Wendling2008-04-011-1/+2
| | | | llvm-svn: 49055
* Change the MemoryBuffer::getFile* methods to take just a pointer to theChris Lattner2008-04-012-17/+10
| | | | | | | | 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
* Reimplement MemoryBuffer::getFile with three enhancements:Chris Lattner2008-04-011-85/+64
| | | | | | | | | | | | | | | | | | | | | 1) stop using MappedFile. 2) if profitable use the sys::path::MapInFilePages api to read the file. 3) otherwise fallback to read. When sys::path::MapInFilePages is implemented, this provides several benefits: #1: this avoids fragmenting memory for small files. #2: this avoids extraneous stat calls when the file size is known. #3: this only keeps the file descriptor open while reading the file, not for the duration of the lifetime of the memory buffer. This fixes a serious clang FD 'leak' problem. I believe that this will work on a win32 machine, but I don't have one to test on. I'd appreciate it if someone could check. llvm-svn: 49031
* Remove the MappedFile::charBase member, rename base -> getBase() andChris Lattner2008-04-011-3/+4
| | | | | | make getBase() return a const-correct pointer. llvm-svn: 49025
* 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 Lattner2008-04-012-3/+3
| | | | | | | and shared. This complicates the design, is not used, and probably doesn't even work. llvm-svn: 49022

| | | | llvm-svn: 48801
* A quick nm audit turned up several fixed tables and objects that wereDan Gohman2008-03-252-2/+2
| | | | | | | marked read-write. Use const so that they can be allocated in a read-only segment. llvm-svn: 48800

| | | | llvm-svn: 48035
* Add support to APInt for shift and rotate operations with APIntDan Gohman2008-02-291-0/+27
| | | | | | instead of uint32_t for the shift/rotate count operand type. llvm-svn: 47741
* Add a method to APFloat to convert directly from APInt.Dan Gohman2008-02-291-0/+17

* Unbreak build with gcc 4.3: provide missed includes and silence most ↵Anton Korobeynikov2008-02-205-0/+5

* Fixed bug in APInt::Profile() where the BitWidth field was not included in theTed Kremenek2008-02-191-0/+2
| | | | | | | profile of the APSInt object. This caused unexpected Profile collisions where none should have occurred. llvm-svn: 47338
* Fixed bug in FoldingSetIteratorImpl where we did not correctly check ifTed Kremenek2008-02-151-2/+4
| | | | | | | we had reached the "fake bucket" after the last bucket, allowing the iterator in some cases to run off the end of the hashtable. llvm-svn: 47178
* Fix a warning about comparison between signed and unsigned,Dan Gohman2008-02-141-1/+1
| | | | | | being consistent with the rest of the APInt implementation. llvm-svn: 47138
* Add countTrailingOnes member functions to APInt.Dan Gohman2008-02-131-0/+12
| | | | llvm-svn: 47086
* Added "Profile" method to APFloat for use with FoldingSet.Ted Kremenek2008-02-112-11/+6
| | | | | | | | | | Added member template "Add" to FoldingSetNodeID that allows "adding" arbitrary objects to a profile via dispatch to FoldingSetTrait<T>::Profile(). Removed FoldingSetNodeID::AddAPFloat and FoldingSetNodeID::APInt, as their functionality is now replaced using the above mentioned member template. llvm-svn: 46957
* Add support to FoldingSet for hashing APInt objects.Dan Gohman2008-02-061-0/+4
| | | | llvm-svn: 46833
