Dan Gohman 191f2e4dbd Change an argument from an Instruction* to a Value*, which is all 
that is needed here.

Gabor Greif 704524ae70 initial checkin for unittest to exercise Support/Casting.h 
this is still minimal on purpose, but I plan to migrate the ugly
hack under #ifdef DEBUG_CAST_OPERATORS into this file

Jim Grosbach 3680f70c9d Using BIC for immediates needs an extra bump for its complexity to get 
instruction selection to prefer it when possible. rdar://7903972

Jakob Stoklund Olesen 36d12c679d Beginning SplitKit - utility classes for live range splitting. 
This is a work in progress. So far we have some basic loop analysis to help
determine where it is useful to split a live range around a loop.

The actual loop splitting code from Splitter.cpp is also going to move in here.

Lang Hames a475ab7f02 Use run-length encoding to represent identical adjacent cells in the pressure 
and interval table. Reduces output HTML file sizes by ~80% in my test cases.

Also fix access of private member type by << operator.

Bruno Cardoso Lopes 160695fecb Fix PR7174, a couple o Mips fixes: 
- Fix a typo for PIC check during jmp table lowering
- Also fix the "first jump table basic block is not
considered only reachable by fall through" problem, use this
ad-hoc solution until I come up with something better.

Owen Anderson 81781220d2 Speculatively revert r108813, in an attempt to get the self-host buildbots working again. I don't see why this patch 
would cause them to fail the way they are, but none of the other intervening patches seem likely either.

Lang Hames a93fe2de3c Switched to rendering after allocation (but before rewriting) in PBQP. 
Updated renderer to use allocation information from VirtRegMap (if
available) to render spilled intervals differently.

Dale Johannesen 08645f1991 Don't hoist things out of a large switch inside a 
loop, for the reasons in the comments.  This is a
major win on 253.perlbmk on ARM Darwin.  I expect it
to be a good heuristic in general, but it's possible
some things will regress; I'll be watching.

Chris Lattner b792b463af sink the arm implementations of ASmPrinter and MCInstLower 
out of the AsmPrinter directory into libarm.  Now the
ARM InstPrinters depend jsut on the MC stuff, not on vmcore
or codegen.

Chris Lattner 64fffadad3 fix a layering problem by moving the x86 implementation 
of AsmPrinter and InstLowering into libx86 and out of the
asmprinter subdirectory.  Now X86/AsmPrinter just depends on
MC stuff, not all of codegen and LLVM IR.

Dan Gohman b5e918dc05 After a custom inserter, in a block which has constant instructions, 
update the current basic block in addition to the current insert
position, so that they remain consistent. This fixes rdar://8204072.

Owen Anderson 0edf6a1131 Change the implemented interfaces list on PassInfo from a std::vector to a manually implemented 
linked list.  This is a little slower and involves more malloc'ing, but these lists are
typically short, and it allows PassInfo to be entirely constant initializable.

Bob Wilson a7d44a1ab6 Save a copy of the unstripped libLTO.dylib in $SYM_DIR. Clean up the code 
for dealing with libLTO.dylib to put it all in one place and to allow
use of DISABLE_USR_LINKS.

Daniel Dunbar 6b4391aa69 MC/Mach-O: Silently ignore .file directives instead of error'ing out on 
them. They aren't important enough to abort the entire assembly, and failing
early makes testing more annoying.

Daniel Dunbar 9db7d0addd X86: Mark JMP{32,64}[mr] as requires 32-bit/64-bit mode. They are the same 
instruction, we only want to allow the one for the current subtarget.
 - This also fixes suffix matching for jmp instructions, because it eliminates
   the ambiguity between 'jmpl' and 'jmpq'.

Evan Cheng 7a135510e3 Teach computeRegisterProperties() to compute "representative" register class for legal value types. A "representative" register class is the largest legal super-reg register class for a value type. e.g. On i386, GR32 is the rep register class for i8 / i16 / i32; on x86_64 it would be GR64. 
This property will be used by the register pressure tracking instruction scheduler.

Jim Grosbach 8d3ba7349c Since ARM emits inline jump tables as part of the ConstantIsland pass, 
it should set the jump table encloding the EK_Inline. This prevents
a second, unused, copy of the table from being emitted after the function
body. PR6581.
