Evan Cheng 34806b1fa4 If two-address def is dead and the instruction does not define other registers, and it doesn't produce side effects, just delete the instruction.

Evan Cheng 107b06c4b9 Teach LSR sink to sink the immediate portion of the common expression back into uses if they fit in address modes of all the uses.

pointer types.

Chris Lattner bef6b2098e rename a function to indicate that it checks for profitability as well
as legality.  Make load sinking and gep sinking more careful: we only
do it when it won't pessimize loads from the stack.  This has the added
benefit of not producing code that is unanalyzable to SROA.

Bill Wendling 5191934371 We need to propagate the debug location information even when dealing with the

Misha Brukman 0f35659b9a * Fixed spelling
* Linters now return their information instead of printing it, to
  enable easier unittesting

Dan Gohman e7fe80fcf9 Fix a bug that David Greene found in the DAGCombiner's logic
that checks whether it's safe to transform a store of a bitcast
value into a store of the original value.

Chris Lattner 70946da73a switch the macroinfo argument lists from being allocated off the heap
to being allocated from the same bumpptr that the MacroInfo objects 
themselves are.

This speeds up -Eonly cocoa.h pth by ~4%, fsyntax-only is barely measurable.

Misha Brukman 5e5503f5da Keep the newline character at the end of the lines whose trailing whitespace we
are deleting; otherwise, everything ends up on a single line.

Misha Brukman f2e5bd8d22 Only strip the newline character at the end of the lines that we're considering
for length and for trailing whitespace; otherwise, the whitespace themselves
will also be removed.

Bill Wendling 4d38d7272e We have logic in there to emit a default debugging label at the beginning of a
function. Emitting another label after the prologue messes up the debugging. We
are doing that because the first DebugLoc object it sees is different from the
previous, which was nothing. Check for this situation, and don't emit one if
it's the first.

Evan Cheng 8a9481d50d Fix strange logic in CollectIVUsers used to determine whether all uses are
addresses, part 1. This fixes an obvious logic bug. Previously if the only
in-loop use is a PHI, it would return AllUsesAreAddresses as true.

Chris Lattner 7c981a79f7 allocate and dellocate objc decl list through AST Context instead of
with new/delete.  With disable-free, this reduces the number of 4/8 byte
mallocs from 4793/1541 to 865/456 and also drops other sizes as well.

This is a very small perf win, nothing major.

Ted Kremenek b087942765 Greatly simplify the logic in ExplodedGraphImpl::TrimGraph. Now we just do a
vanilla reverse-BFS followed by a forward-DFS instead of resulting to strange
histrionics (whose purpose I can no longer remember) in the reverse-BFS stage.
This fixes an assertion failure in BugReporter due to edge cases where no root
was being hit in the reverse-BFS phase.
