2009-08-19Change ValueSymbolTable to use raw_svector_ostream for string concatenation.Daniel Dunbar

2009-08-19Change raw_svector_ostream to reserve the input buffer if necessary, Ted wasDaniel Dunbar
right. - This class turns out to be much more convenient to use if we do this; clients can make sure the buffer is always big enough if they care (since our current idiom tends to be to use a SmallString<256> for the input to this we should generally be avoiding an unnecessary malloc). Also, add a convenience raw_svector_ostream::str method which flushes the buffer and returns a StringRef for the vector contents. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79446 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-19Make SROA and PredicateSimplifier cope if TargetData is notDan Gohman
available. This is very conservative for now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79442 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-19Use hasDefinitiveInitializer() instead of testing the same thingDan Gohman
by hand, and fix a few places that were using hasInitializer() that appear to depend on the initializer value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79441 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-19Canonicalize indices in a constantexpr GEP. If Indices exceed theDan Gohman
static extents of the static array type, it causes GlobalOpt and other passes to be more conservative. This canonicalization also allows the constant folder to add "inbounds" to GEPs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79440 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-19Add an x86 peep that narrows TEST instructions to forms that useDan Gohman
a smaller encoding. These kinds of patterns are very frequent in sqlite3, for example. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79439 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-19Switch Twine::str() to use toVector(), which is now efficient.Daniel Dunbar
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79437 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79435 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-19Switch raw_svector_ostream to use the vector as the ostream buffer.Daniel Dunbar
- This avoids unnecessary malloc/free overhead in the common case, and unnecessary copying from the ostream buffer into the output vector. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79434 91177308-0d34-0410-b5e6-96231b3b80d8
2009-08-19Add SmallVector::{capacity,set_size}.Daniel Dunbar
- 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79433 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-19Add support for Neon VEXT (vector extract) shuffles.Bob Wilson
This is derived from a patch by Anton Korzh. I modified it to recognize the VEXT shuffles during legalization and lower them to a target-specific DAG node. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79428 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-19Fix gcc-4.4/fedora 11 by adding a sentinel value to SimpleValueType.Erick Tryzelaar
gcc-4.4 was optimizing away comparisons against SimpleValueType when it was compared to a value larger than the largest value in the enum. This patch works around it by adding one extra item to the enum so that these tests will now be valid. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79401 91177308-0d34-0410-b5e6-96231b3b80d8

2009-08-18raw_ostream: Reduce FormattedStream's reliance on raw_ostream's implementation.Daniel Dunbar
- Kill off begin(), end(), and iterator. It isn't clear what these mean. Instead provide getBufferStart(), which can be used with GetNumBytesInBuffer to the same effect. - Update ComputeColumn to take arguments for the buffer to scan, this simplifies the implementation of write_impl substantially. - This should also fix possible problems with the scanning pointer pointing outside of the current raw_ostream buffer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@79379 91177308-0d34-0410-b5e6-96231b3b80d8
