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

Daniel Dunbar ff53d4694c Add an implementation of the delta debugging algorithm. 
- This is a pretty slow / memory intensive implementation, and I will likely
   change it to an iterative model, but it works.

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.

Rafael Espindola ff2c72b858 Distinguish "a," from "a". The first one splits into "a" + "" and the second one into 
"a" + 0.

Jeffrey Yasskin b40d3f76a0 Fix DenseMap iterator constness. 
This patch forbids implicit conversion of DenseMap::const_iterator to
DenseMap::iterator which was possible because DenseMapIterator inherited
(publicly) from DenseMapConstIterator. Conversion the other way around is now
allowed as one may expect.

The template DenseMapConstIterator is removed and the template parameter
IsConst which specifies whether the iterator is constant is added to
DenseMapIterator.

Actually IsConst parameter is not necessary since the constness can be
determined from KeyT but this is not relevant to the fix and can be addressed
later.

Patch by Victor Zverovich!

Jeffrey Yasskin 4546d31235 Try r84890 again (adding ValueMap<>), now that I've tested the compile on 
gcc-4.4.

llvm-svn: 84892
 2009-10-22 20:23:43 +00:00
Jeffrey Yasskin 6b80e6e2b7 Add a ValueMap<ValueOrSubclass*, T> type. ValueMap<Value*, T> is safe to use 
even when keys get RAUWed and deleted during its lifetime. By default the keys
act like WeakVHs, but users can pass a third template parameter to configure
how updates work and whether to do anything beyond updating the map on each
action.

It's also possible to automatically acquire a lock around ValueMap updates
triggered by RAUWs and deletes, to support the ExecutionEngine.

Chris Lattner 0ffe0e096d split raw_os_ostream out to its own header and implementation file. This 
means that raw_ostream no longer has to #include <iosfwd>.  Nothing in llvm
should use raw_os_ostream.h, but llvm-gcc and some unit tests do.

Daniel Dunbar 825e955e40 Add SmallVector::{capacity,set_size}. 
- These allow clients to make use of the extra elements in the vector which
   have already been allocated, without requiring them to be value initialized.

 2009-08-17 00:14:11 +00:00
Erick Tryzelaar 19f63b2e4d Modify APFloat to take a StringRef instead of a c string. 
This also adds unit tests to APFloat that mainly tests the
string handling of APFloat, but not much else of it's api.

Daniel Dunbar b49994ad7e Twines: Support numeric conversion directly (uitostr, etc). 
- Provides static constructors for doing number to string conversions without
   using temporaries.

 - There are several ways to do this, I think given the Twine constraints this
   is the simplest one.

 - One FIXME for fast number -> hex conversion.

 - Added another comment on one last major bit of perf work Twines need, which
   is to make raw_svector_ostream more efficient.

llvm-svn: 77445
 2009-07-29 07:08:44 +00:00
Daniel Dunbar 19e7076ddd Update Triple to use StringRef/Twine based APIs. 
- This is now shorter, simpler, safer, and more efficient, what a deal.

 2009-07-26 03:31:47 +00:00
Daniel Dunbar 56563f33f7 Add StringRef::{slice, split}, two convenient string operations which are simple

Jeffrey Yasskin f4e1db1722 Add a missing ilist_node.h #include to SparseBitVector, and add a very short 
test for it. The test is by no means complete, but it tests the problem I was
fixing.
