Chris Lattner 93a95ae8a9 force clients of MachineFunction::getMachineMemOperand to provide a
MachinePointerInfo, propagating the type out a level of API.  Remove
the old MachineFunction::getMachineMemOperand impl.

Bill Wendling dfc2c51d12 It's better to have the arrays, which would trigger the creation of stack
protectors, to be near the stack protectors on the stack. Accomplish this by
tagging the stack object with a predicate that indicates that it would trigger
this. In the prolog-epilog inserter, assign these objects to the stack after the
stack protector but before the other objects.

Jim Grosbach 734738d3bd Remove too-strict assertion. We may want the vreg copy of the physical register
to be of a different register class. For example, in Thumb1 if the live-in is
a high register, we want the vreg to be a low register. rdar://8224931

Bill Wendling 207855cff9 Introducing the "linker_weak" linkage type. This will be used for Objective-C
metadata types which should be marked as "weak", but which the linker will
remove upon final linkage. For example, the "objc_msgSend_fixup_alloc" symbol is
defined like this:

       .globl l_objc_msgSend_fixup_alloc
       .weak_definition l_objc_msgSend_fixup_alloc
       .section __DATA, __objc_msgrefs, coalesced
       .align 3
l_objc_msgSend_fixup_alloc:
        .quad   _objc_msgSend_fixup
        .quad   L_OBJC_METH_VAR_NAME_1

This is different from the "linker_private" linkage type, because it can't have
the metadata defined with ".weak_definition".

David Greene 5c8aa950fe Ok, third time's the charm. No changes from last time except the CMake
source addition.  Apparently the buildbots were wrong about failures.

Add some switches helpful for debugging:

-print-before=<Pass Name>

Dump IR before running pass <Pass Name>.

-print-before-all

Dump IR before running each pass.

-print-after-all

Dump IR after running each pass.

These are helpful when tracking down a miscompilation.  It is easy to
get IR dumps and do diffs on them, etc.

To make this work well, add a new getPrinterPass API to Pass so that
each kind of pass (ModulePass, FunctionPass, etc.) can create a Pass
suitable for dumping out the kind of object the Pass works on.

Chris Lattner de4845c163 Switch the code generator (except the JIT) onto the new DebugLoc
representation.  This eliminates the 'DILocation' MDNodes for 
file/line/col tuples from -O0 -g codegen.

This remove the old DebugLoc class, making it a typedef for DebugLoc,
I'll rename NewDebugLoc next.

I didn't update the JIT to use the new apis, so it will continue to
work, but be as slow as before.  Someone should eventually do this
or, better yet, rip out the JIT debug info stuff and build the JIT
on top of MC.

David Greene 434bd8551d Let's try this again. Re-apply 100143 including an apparent missing
<string> include.  For some reason the buildbot choked on this while my
builds did not.  It's probably due to a difference in system headers.

Chris Lattner 9b97a73ded Rip out the 'is temporary' nonsense from the MCContext interface to
create symbols.  It is extremely error prone and a source of a lot
of the remaining integrated assembler bugs on x86-64.

This fixes rdar://7807601.

Bob Wilson 80d23705e6 Stop trying to merge identical jump tables. This had been inadvertently
disabled for several months (since svn r88806) and no one noticed.  My fix
for pr6543 yesterday reenabled it, but broke the ARM port's code for using
TBB/TBH.  Rather than adding a target hook to disable merging for Thumb2 only,
I'm just taking this out.  It is not common to have identical jump tables,
the code we used to merge them was O(N^2), and it only helps code size, not
performance.

Bob Wilson d1ec31dca5 Fix pr6543: svn r88806 changed MachineJumpTableInfo::getJumpTableIndex() to
always create a new jump table.  The intention was to avoid merging jump
tables in SelectionDAGBuilder, and to wait for the branch folding pass to
merge tables.  Unfortunately, the same getJumpTableIndex() method is also
used to merge tables in branch folding, so as a result of this change
branch tables are never merged.  Worse, the branch folding code is expecting
getJumpTableIndex to always return the index of an existing table, but with
this change, it never does so.  In at least some cases, e.g., pr6543, this
creates references to non-existent tables.

I've fixed the problem by adding a new createJumpTableIndex function, which
will always create a new table, and I've changed getJumpTableIndex to only
look at existing tables.

Chris Lattner 11d53c129f rearrange MCContext ownership. Before LLVMTargetMachine created it
and passing off ownership to AsmPrinter.  Now MachineModuleInfo
creates it and owns it by value.  This allows us to use MCSymbols
more consistently throughout the rest of the code generator, and
simplifies a bit of code.  This also allows MachineFunction to 
keep an MCContext reference handy, and cleans up the TargetRegistry
interfaces for AsmPrinters.
