* Change all self assignments X=X to (void)X, so that we can turn on aJeffrey Yasskin2010-12-232-3/+2
| | | | | | | new gcc warning that complains on self-assignments and self-initializations. llvm-svn: 122458
* Use IntEqClasses to compute connected components of live intervals.Jakob Stoklund Olesen2010-12-211-0/+1
| | | | llvm-svn: 122296
* Add ADT/IntEqClasses.h as a light-weight implementation of EquivalenceClasses.h.Jakob Stoklund Olesen2010-12-212-0/+70
| | | | | | | | | | This implementation already exists as ConnectedVNInfoEqClasses in LiveInterval.cpp, and it seems to be generally useful to have a light-weight way of forming equivalence classes of small integers. IntEqClasses doesn't allow enumeration of the elements in a class. llvm-svn: 122293

| | | | llvm-svn: 122026
* MemoryBuffer now return an error_code and returns a OwningPtr<MemoryBuffer> ↵Michael J. Spencer2010-12-164-48/+50
| | | | | | via an out parm. llvm-svn: 121958
* lib/Support/regexec.c: Let Regex LLP64-aware.NAKAMURA Takumi2010-12-161-2/+3
| | | | | | On LLP64 Win64, 'states1' (for small version) was expanded to 'char *' for large version. Thus small version would be mischosen when nstates > 32 regardless of sizeof(long) on Win64. llvm-svn: 121942

| | | | | | templated c_str in Windows.h to replace it. llvm-svn: 121381
* Support/FileSystem: Change file_status predicate functions that cannot fail toMichael J. Spencer2010-12-091-0/+27
| | | | | | | return their result instead of an error_code. Also add some missing predicate functions. llvm-svn: 121380
* Support/MemoryBuffer: Replace all uses of std::string *ErrMsg with ↵Michael J. Spencer2010-12-095-26/+50
| | | | | | error_code &ec. And fix clients. llvm-svn: 121379

| | | | llvm-svn: 121160
* Support/PathV2: Remove const from bool return types.Michael J. Spencer2010-12-071-9/+9
| | | | llvm-svn: 121157
* Support/PathV2: Change most functions in the path namespace to return their workMichael J. Spencer2010-12-073-104/+64
| | | | | | via their return value instead of an out parameter. llvm-svn: 121149
* build: Go back to dropping __eprintf reference when building with Clang, seeDaniel Dunbar2010-12-071-0/+5
| | | | | | comment. llvm-svn: 121146
* PR5207: Change APInt methods trunc(), sext(), zext(), sextOrTrunc() andJay Foad2010-12-074-87/+75
| | | | | | | | 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/PathV2: Remove the error_code return type from all functions in the pathMichael J. Spencer2010-12-073-95/+65

| | | | llvm-svn: 121108
* Support/Unix/PathV2: Return the real error from realpath instead of any errorMichael J. Spencer2010-12-071-1/+2
| | | | | | that close or unlink set. llvm-svn: 121094
* Support/Unix/PathV2: Use 0770 instead of 0700 when creating a directory. ↵Michael J. Spencer2010-12-071-1/+1
| | | | | | | | Also use the standard macros instead of octal notation. llvm-svn: 121093

* Silence 'may be used uninitialized in this function' warnings. Static analysisBill Wendling2010-12-041-2/+2
| | | | | | | may determine that they cannot be used uninitialized. But that might be a bit too much for the compiler to determine. llvm-svn: 120916

* Add IntervalMap::iterator::set{Start,Stop,Value} methods that allow limitedJakob Stoklund Olesen2010-12-031-3/+3
| | | | | | | | | | | editing of the current interval. These methods may cause coalescing, there are corresponding set*Unchecked methods for editing without coalescing. The non-coalescing methods are useful for applying monotonic transforms to all keys or values in a map without accidentally coalescing transformed and untransformed intervals. llvm-svn: 120829
