Joerg Sonnenberger 6c4dc2b218 Add a Python-like join function to merge a list of strings with a 
separator between each two elements.

Nick Kledzik 85a62b1a1d Use unsigned long long instead of uin64_t for OS where that matters.

Benjamin Kramer d95ceff092 Don't call getAsUnsignedInteger directly, it fails to compile if uint64_t is not "unsigned long long". 
while there add more test cases.

Nick Kledzik f8a75eef85 Add getAsUnsignedInteger test case that checks that known bad values are rejected

Michael J. Spencer 93303819ac [Support/StringRef] Add find_last_not_of and {r,l,}trim.

Michael J. Spencer cfa95f66a1 Make StringRef::getAsInteger work with all integer types. Before this change 
it would fail with {,u}int64_t on x86-64 Linux.

This also removes code duplication.

Chandler Carruth ca99ad3f0d Add generic support for hashing StringRef objects using the new hashing library.

Benjamin Kramer 4d681d7dc4 Add a bad char heuristic to StringRef::find. 
Based on Horspool's simplified version of Boyer-Moore. We use a constant-sized table of
uint8_ts to keep cache thrashing low, needles bigger than 255 bytes are uncommon anyways.

The worst case is still O(n*m) but we do a lot better on the average case now.

Jakob Stoklund Olesen c874e2d8fb Fix a bug in compare_numeric(). 
Thanks to Alexandru Dura and Jonas Paulsson for finding it.

Lenny Maiorani 367342e209 Remove bounded StringRef::compare() since nothing but Clang SA was using it and it is just as easy to use StringRef::substr() preceding StringRef::compare() to achieve the same thing.

Lenny Maiorani fad9d95722 Implements StringRef::compare with bounds. It is behaves similarly to strncmp(). Unit tests also included.

Benjamin Kramer 9bf0380a54 StringRef::compare_numeric also differed from StringRef::compare for characters > 127.

Benjamin Kramer b04d4af057 Do unsigned char comparisons in StringRef::compare_lower to be more consistent with compare in corner cases.

Jakob Stoklund Olesen d1d7ed63ff Add StringRef::compare_numeric and use it to sort TableGen register records. 
This means that our Registers are now ordered R7, R8, R9, R10, R12, ...
Not R1, R10, R11, R12, R2, R3, ...

Douglas Gregor 5639af4eac Document the edit-distance algorithm used in StringRef, switch it over 
to SmallVector, and add a unit test.

Douglas Gregor 4ee2cf658c Move the two definitions of operator<< into namespace llvm, so they 
will be found by argument-dependent lookup. As with the previous
commit, GCC is allowing ill-formed code.

Eli Friedman 00879d8faa Change StringRef::startswith and StringRef::endswith to versions which are a 
bit more verbose, but optimize to much shorter code.

 2009-11-19 16:04:41 +00:00
Daniel Dunbar 1acdfbd60b "XFAIL" the Split2 StringReft test with Apple gcc, which miscompiles it. 
- I plan on fixing/workarounding this, but until then I'd like the bots to stay
   green.

"a" + 0.
