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.

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

llvm-svn: 129582

Don't infinitely recurse! Patch by Marius Wachtler!

llvm-svn: 124366

StringRef::compare_numeric also differed from StringRef::compare for characters > 127.

llvm-svn: 112189

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

llvm-svn: 112185

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, ...

Silence compiler warning.

warning: comparison between signed and unsigned integer expressions
llvm-svn: 92359

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

llvm-svn: 92340

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.

llvm-svn: 92146

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

llvm-svn: 91817

Reenable Split2 StringRef test with Apple gcc.

llvm-svn: 89357

"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.

llvm-svn: 89077

Distinguish "a," from "a". The first one splits into "a" + "" and the second one into
"a" + 0.

llvm-svn: 87084

Switch to smallvector. Also fix issue with using unsigend for MaxSplit.

llvm-svn: 87068

Add a new split method to StringRef that puts the substrings in a vector.

llvm-svn: 87058

Add From arguments to StringRef search functions, and tweak doxyments.

Also, add unittests for find_first_of and find_first_not_of.

llvm-svn: 86770

Add StringRef::{rfind, rsplit}

llvm-svn: 82087

Fix pasto in StringRef::count(char)

llvm-svn: 79356

Add StringRef::count({char,StringRef})

llvm-svn: 79354

StringRef: Add find(char) and find(StringRef).

Also, regroup functions.

llvm-svn: 78712

Add StringRef::{slice, split}, two convenient string operations which are simple
and efficient on a StringRef.

llvm-svn: 77117

Support writing a StringRef to a raw_ostream directly.

llvm-svn: 76754

Add StringRef::{substr, startswith}.

llvm-svn: 76559

Add StringRef class, with fixes.
