Gabor Greif de2fb05246 Give sentinel traits the right to determine the policy where the sentinel is kept. 
This should result in less indirect memory accesses, less dead writes and tighter code.

Dan Gohman cc329b567d When using MachineInstr operand indices on SDNodes, the number 
of MachineInstr def operands must be subtracted out. This bug
was uncovered by the recent x86 EFLAGS optimization. Before
that, the only instructions that ever needed unfolding were
things like CMP32rm, where NumDefs is zero.

Nate Begeman 920438ef1d Fix a thinko in the JIT where the address of a GV was only recorded in the map 
on failure to resolve it.
Do not abort on failure to resolve an external symbol when using dlsym stubs,
  since the symbol may not be in the JIT's address space.  Just use 0.
Allow dlsym stubs to differentiate between GlobalVars and Functions.

Steve Naroff d1b64be776 Partial fix for <rdar://problem/6645157> [clang on Xcode; regression]: error: instance variable 'someField' is private. 
A recent regression caused by http://llvm.org/viewvc/llvm-project?rev=65912&view=rev.

This commit isn't fully baked. Nevertheless, it should cause Xcode to compile again. Will speak with Fariborz offline.

Mike Stump 95435674f9 Move more of blocks codegen out of CodeGenModule and into the

don't want to know anything about blocks not be confused by the
overloaded use of the term block or nor want to see all the blocks
goop.

Steve Naroff 3f49feeed5 Finish up some fixes related to <rdar://problem/6497631> Message lookup is sometimes different than gcc's. 
- Disallow casting 'super'. GCC allows this, however it doesn't make sense (super isn't an expression and the cast won't alter lookup/dispatch).
- Tighten up lookup when messaging 'self'.

codegen, until such time as codegen is complete enough to turn on with
-fblocks.

Daniel Dunbar 5637208a88 Driver: More Option implementation. 
- Add Options.def file, collects option information.

 - Actual option instantiation is handled lazily by OptTable to allow
   the driver to not need to instantiate all options.

Gabor Greif a954a99c40 "Ghostify" embedded sentinels. This is a real win in all cases 
because less bytes are allocated and subobject construction is gone.
For reference how it works, see BasicBlock.h.
Btw. it is very assuring to see that somebody has invented
this ilist-embedded sentinel technique before me :-)

Chris Lattner 8322dc809e make the token lexer allocate its temporary token buffers for

Chris Lattner 9631e1871e Switch attributes to be allocated from the declcontext bump pointer just like 
decls.  This reduces the number of calls to malloc on cocoa.h with pth and
-disable-free from 15958 to 12444 times (down ~3500).

Chris Lattner 1a84994c46 allocate MultiKeywordSelector's out of a bump pointer allocator instead of malloc. 
This has two advantages 1) no more leaking them, 2) fewer calls to malloc.

This changes us from calling malloc 3685/1390/883/2974/1185 times respectively on
16/20/24/28/32 byte objects when parsing cocoa.h with pth and -disable-free to
calling it 2816/1020/702/2903/1168 times each respectively.

Chris Lattner 4192bce91b add a special case for codegen that improves the case where we have 
multiple sequential cases to a) not create tons of fall-through basic blocks
and b) not recurse deeply.  This fixes codegen on 100K deep cases, and improves
codegen on moderate cases from this:

        switch i32 %tmp, label %sw.epilog [
                i32 1000, label %sw.bb
                i32 1001, label %sw.bb1
                i32 1002, label %sw.bb2
                i32 1003, label %sw.bb3
                i32 1004, label %sw.bb4
...
sw.bb:          ; preds = %entry
        br label %sw.bb1

sw.bb1:         ; preds = %entry, %sw.bb
        br label %sw.bb2

sw.bb2:         ; preds = %entry, %sw.bb1
        br label %sw.bb3

sw.bb3:         ; preds = %entry, %sw.bb2
        br label %sw.bb4

to:

        switch i32 %tmp, label %sw.epilog [
                i32 1000, label %sw.bb
                i32 1001, label %sw.bb
                i32 1002, label %sw.bb
                i32 1003, label %sw.bb
                i32 1004, label %sw.bb
sw.bb:  ;; many preds

Chris Lattner 34a2209177 Change Parser::ParseCaseStatement to use an iterative approach to parsing 
multiple sequential case statements instead of doing it with recursion.  This
fixes a problem where we run out of stack space parsing 100K directly nested
cases.

There are a couple other problems that prevent this from being useful in 
practice (right now the example only parses correctly with -disable-free and
doesn't work with -emit-llvm), but this is a start.

I'm not including a testcase because it is large and uninteresting for 
regtesting.

Sebastian, I would appreciate it if you could scrutinize the smart pointer 
gymnastics I do.
