This is much faster than using a pointer to a ManagedStatic object accessed with
a function call. The greedy register allocator is 5% faster overall just from
the SlotIndex default constructor savings.

llvm-svn: 126925

The SlotIndex created by the default construction does not represent a position
in the function, and it doesn't make sense to compare it to other indexes.

llvm-svn: 126924

IndexListEntries have unique indexes, so it is not necessary to dereference
pointers to them.

llvm-svn: 126923

llvm-svn: 126922

This speeds up the greedy register allocator by 15%.
DenseMap is not as fast as one might hope.

parameter, save the instantiated default template arguments along with
the explicitly-specified template argument list. That way, we prefer
the default template template arguments corresponding to the template
template parameter rather than those of its template template argument.

This addresses the likely direction of C++ core issue 150, and fixes
PR9353/<rdar://problem/9069136>, bringing us closer to the behavior of
EDG and GCC.

http://llvm.org/bugs/show_bug.cgi?id=9349 I introduced a bug with the last fix and Ryuta Suzuki has corrected it.  And hopefully I committed Ryuta Suzuki's directions correctly this time.

// When stopped on breakppint 1, and then 2, we can get the line entries using
// SBFrame API SBFrame.GetLineEntry().  We'll get the start addresses for the
// two line entries; with the start address (of SBAddress type), we can then
// resolve the symbol context using the SBTarget API
// SBTarget.ResolveSymbolContextForAddress().
//
// The two symbol context should point to the same symbol, i.e., 'a' function.


Add two utility functions to lldbutil.py:

o get_stopped_threads(process, reason):

  return the list of threads with the specified stop reason or an empty list if not found

o get_stopped_thread(process, reason):

  return the first thread with the given stop reason or None if not found

Patch by Jyun-Yan You, with some minor adjustments and a testcase from me.

When only a single value has been seen, new PHIDefs are never needed.

llvm-svn: 126911

llvm-svn: 126910

llvm-svn: 126909

llvm-svn: 126907

We need to wait until we meet a PHIDef in its defining block before resurrecting
PHIKills in the predecessors.

This should unbreak the llvm-gcc-build-x86_64-darwin10-x-mingw32-x-armeabi bot.

Fix bug where bitwise-AND was being used and it should have been bitwise-OR.

David Greene changed CannotYetSelect() to print the full DAG including multiple
copies of operands reached through different paths in the DAG.  Unfortunately
this blows up exponentially in some cases.  The depth limit of 100 is way too
high to prevent this -- I'm seeing a message string of 150MB with a depth of
only 40 in one particularly bad case, even though the DAG has less than 200
nodes.  Part of the problem is that the printing code is following chain
operands, so if you fail to select an operation with a chain, the printer will
follow all the chained operations back to the entry node.

Patch by Ted Kremenek!

llvm-svn: 126895

Values that map to a single new value in a new interval after splitting don't
need new PHIDefs, and if the parent value was never rematerialized the live
range will be the same.
