* Remove bounded StringRef::compare() since nothing but Clang SA was using it ↵Lenny Maiorani2011-04-281-21/+0
| | | | | | and it is just as easy to use StringRef::substr() preceding StringRef::compare() to achieve the same thing. llvm-svn: 130430
* Implements StringRef::compare with bounds. It is behaves similarly to ↵Lenny Maiorani2011-04-151-0/+21
| | | | | | strncmp(). Unit tests also included. llvm-svn: 129582
* Fix a ton of comment typos found by codespell. Patch byChris Lattner2011-04-151-2/+2
| | | | | | Luis Felipe Strano Moraes! llvm-svn: 129558
* PR5207: Change APInt methods trunc(), sext(), zext(), sextOrTrunc() andJay Foad2010-12-071-1/+1
| | | | | | | | zextOrTrunc(), and APSInt methods extend(), extOrTrunc() and new method trunc(), to be const and to return a new value instead of modifying the object in place. llvm-svn: 121120
* Support/ADT/StringRef: Add find_last_of.Michael J. Spencer2010-11-301-0/+15

* Fix memory leak in StringRef::edit_distance(). 'Allocated' could be leaked ↵Ted Kremenek2010-11-071-5/+6

* Extend StringRef's edit-distance algorithm to permit an upper bound on the ↵Douglas Gregor2010-10-191-1/+8

* StringRef::compare_numeric also differed from StringRef::compare for ↵Benjamin Kramer2010-08-261-1/+1
| | | | | | characters > 127. llvm-svn: 112189
* Do unsigned char comparisons in StringRef::compare_lower to be more ↵Benjamin Kramer2010-08-261-4/+4
| | | | | | consistent with compare in corner cases. llvm-svn: 112185
* Avoid O(n*m) complexity in StringRef::find_first(_not)_of(StringRef).Benjamin Kramer2010-08-231-4/+13
| | | | | | | | - Cache used characters in a bitset to reduce memory overhead to just 32 bytes. - On my core2 this code is faster except when the checked string was very short (smaller than the list of delimiters). llvm-svn: 111817
* Add StringRef::compare_numeric and use it to sort TableGen register records.Jakob Stoklund Olesen2010-05-261-0/+28
| | | | | | | This means that our Registers are now ordered R7, R8, R9, R10, R12, ... Not R1, R10, R11, R12, R2, R3, ... llvm-svn: 104745
* Add an override to StringRef::getAsInteger which parses into an APInt.John McCall2010-02-281-12/+93
| | | | | | | | | | It gets its own implementation totally divorced from the (presumably performance-sensitive) routines which parse into a uint64_t. Add APInt::operator|=(uint64_t), which is situationally much better than using a full APInt. llvm-svn: 97381
* More trivial optimizations to a function well outside the critical pathDouglas Gregor2010-01-071-15/+8
| | | | llvm-svn: 92896
* Switch StringRef::edit_distance over to using raw pointers, since bothDouglas Gregor2010-01-071-7/+25
| | | | | | | std::vector and llvm::SmallVector have annoying performance tradeoffs. No, I don't expect this to matter, and now it won't. llvm-svn: 92884
* Document the edit-distance algorithm used in StringRef, switch it overDouglas Gregor2009-12-311-5/+14
| | | | | | to SmallVector, and add a unit test. llvm-svn: 92340
* Implement edit distance for StringRefDouglas Gregor2009-12-301-0/+31
| | | | llvm-svn: 92309
* Use StringRef::min instead of std::min.Daniel Dunbar2009-11-191-5/+5
| | | | llvm-svn: 89372
* Add compare_lower and equals_lower methods to StringRef. Switch all users ofBenjamin Kramer2009-11-121-0/+20
| | | | | | StringsEqualNoCase (from StringExtras.h) to it. llvm-svn: 87020
* Add From arguments to StringRef search functions, and tweak doxyments.Daniel Dunbar2009-11-111-9/+24
| | | | | | Also, add unittests for find_first_of and find_first_not_of. llvm-svn: 86770
* Pass StringRef by value.Daniel Dunbar2009-11-061-3/+3

* add some more overloads of StringRef::getAsInteger forChris Lattner2009-09-191-0/+45
| | | | | | common and useful integer types. llvm-svn: 82338
* provide a "strtoull" operation that works on StringRef's.Chris Lattner2009-09-191-0/+63
