dcea16313d Indirect tail call has to go through a call preserved register since it's after callee register pops. X86 isel lowering is using EAX / R11 and it was somehow adding that to function live out. That prevented the real function return register from being added to the function live out list and bad things happen. 
This fixes 483.xalancbmk (with tail call opt).

c4b94e02af Rewrite FP constant handling in DEBUG_VALUE yet 
again, so it more or less handles long double.
Restore \n removed in latest MC frenzy.

12ce0de462 Added support for X86 instruction prefixes so llvm-mc can assemble them. The 
Lock prefix, Repeat string operation prefixes and the Segment override prefixes.
Also added versions of the move string and store string instructions without the
repeat prefixes to X86InstrInfo.td. And finally marked the rep versions of
move/store string records in X86InstrInfo.td as isCodeGenOnly = 1 so tblgen is
happy building the disassembler files.

90cfc130d6 Fix a gross typo: ARMv6+ may or may not support unaligned memory operations. 
Even if they are suported by the core, they can be disabled
(this is just a configuration bit inside some register).

Allow unaligned memops on darwin and conservatively disallow them otherwise.

b834f5d13d MC/X86 AsmParser: Handle absolute memory operands correctly. We were doing 
something totally broken and parsing them as immediates, but the .td file also
had the wrong match class so things sortof worked. Except, that is, that we
would parse
  movl $0, %eax
as
  movl 0, %eax
Feel free to guess how well that worked.

f0356fe140 Kill ModuleProvider and ghost linkage by inverting the relationship between 
Modules and ModuleProviders. Because the "ModuleProvider" simply materializes
GlobalValues now, and doesn't provide modules, it's renamed to
"GVMaterializer". Code that used to need a ModuleProvider to materialize
Functions can now materialize the Functions directly. Functions no longer use a
magic linkage to record that they're materializable; they simply ask the
GVMaterializer.

Because the C ABI must never change, we can't remove LLVMModuleProviderRef or
the functions that refer to it. Instead, because Module now exposes the same
functionality ModuleProvider used to, we store a Module* in any
LLVMModuleProviderRef and translate in the wrapper methods.  The bindings to
other languages still use the ModuleProvider concept.  It would probably be
worth some time to update them to follow the C++ more closely, but I don't
intend to do it.

Fixes http://llvm.org/PR5737 and http://llvm.org/PR5735.

to take a MachineFunction to match.

Next, move the X86 code that create a PICBase symbol to
X86TargetLowering::getPICBaseSymbol from 
X86MCInstLower::GetPICBaseSymbol, which was an asmprinter specific 
library.  This eliminates a 'gross hack', and allows us to
implement X86ISelLowering::getPICJumpTableRelocBaseExpr which now
calls it.

This in turn allows us to eliminate the 
X86AsmPrinter::printPICJumpTableSetLabel method, which was the
only overload of printPICJumpTableSetLabel.

is currently smashed into the mcsymbol name, but otherwise this is
much cleaner.

071c62fad0 Rearrange handling of jump tables. Highlights: 
1. MachineJumpTableInfo is now created lazily for a function the first time
   it actually makes a jump table instead of for every function.
2. The encoding of jump table entries is now described by the
   MachineJumpTableInfo::JTEntryKind enum.  This enum is determined by the
   TLI::getJumpTableEncoding() hook, instead of by lots of code scattered
   throughout the compiler that "knows" that jump table entries are always
   32-bits in pic mode (for example).
3. The size and alignment of jump table entries is now calculated based on
   their kind, instead of at machinefunction creation time.

Future work includes using the EntryKind in more places in the compiler,
eliminating other logic that "knows" the layout of jump tables in various
situations.

This #if 0's out 3 unit tests, because gtest requires RTTI information.

a10756ee65 Re-implement the main strength-reduction portion of LoopStrengthReduction. 
This new version is much more aggressive about doing "full" reduction in
cases where it reduces register pressure, and also more aggressive about
rewriting induction variables to count down (or up) to zero when doing so
reduces register pressure.

It currently uses fairly simplistic algorithms for finding reuse
opportunities, but it introduces a new framework allows it to combine
multiple strategies at once to form hybrid solutions, instead of doing
all full-reduction or all base+index.

e45ab8a0a9 For aligned load/store instructions, it's only required to know whether a 
function can support dynamic stack realignment. That's a much easier question
to answer at instruction selection stage than whether the function actually
will have dynamic alignment prologue. This allows the removal of the
stack alignment heuristic pass, and improves code quality for cases where
the heuristic would result in dynamic alignment code being generated when
it was not strictly necessary.

74bfe21b50 Now that we have everything nicely factored (e.g. asmprinter is not 
doing global variable classification anymore) and hookized, sink almost
all target targets global variable emission code into AsmPrinter and out
of each target.

Some notes:

1. PIC16 does completely custom and crazy stuff, so it is not changed.
2. XCore has some custom handling for extra directives.  I'll look at it next.
3. This switches linux/ppc to use .globl instead of .global.  If .globl is
   actually wrong, let me know and I'll fix it.
4. This makes linux/ppc get a lot of random cases right which were obviously
   wrong before, it is probably now a bit healthier.
5. Blackfin will probably start getting .comm and other things that it didn't
   before.  If this is undesirable, it should explicitly opt out of these
   things by clearing the relevant fields of MCAsmInfo.

This leads to a nice diffstat:
 14 files changed, 127 insertions(+), 830 deletions(-)

aac138e84d Cleanup handling of .zerofill on darwin: 
1. TargetLoweringObjectFileMachO should decide if something
   goes in zerofill instead of having every target do it.
2. TargetLoweringObjectFileMachO should assign said symbols to
   the right MCSection, the asmprinters should just emit to the
   right section.
3. Since all zerofill stuff goes through mcstreamer anymore,
   MAI can have a bool "haszerofill" instead of having the textual
   directive to emit.

eb231ce51d The most significant encoding bit of GPR:$src or GPR:$dst was over-specified in 
the various MOV (register) instructions (16-bit Thumb), including tBRIND (the
indirect branch).  Instead of '1', it should be specified as '?', because GPR
only specifies the register class, which includes both hi-and-lo registers.

the other one.

9898671a74 Split the TargetAsmParser "ParseInstruction" interface in half: 
the new ParseInstruction method just parses and returns a list of
target operands.  A new MatchInstruction interface is used to

This requires new/deleting all the operands, but it also gives 
targets the ability to use polymorphic operands if they want to.

mode.

069e100f9a Don't fold insufficiently aligned ldr/str into ldm/stm instructions. 
An unaligned ldr causes a trap, and is then emulated by the kernel with
awesome performance. The darwin kernel does not emulate unaligned ldm/stm
Thumb2 instructions, so don't generate them.

This fixes the miscompilation of Multisource/Applications/JM/lencod for Thumb2.

Generating unaligned ldr/str pairs from a 16-bit aligned memcpy is probably
also a bad idea, but that is beyond the scope of this patch.

2. Change a bunch of targets to call makeNameProper with a smallstring,
   making several of them *much* more efficient.
3. Rewrite Mangler::makeNameProper to not build names and then prepend
   prefixes, not use temporary std::strings, and to avoid other crimes.

- SplitString is a StringRef::split variant for more than 2 elements with the
  same behaviour as getToken.

e5dacc55ad Use a 32-bit and with implicit zero-extension instead of a 64-bit and if it 
has an immediate with at least 32 bits of leading zeros, to avoid needing to
materialize that immediate in a register first.

FileCheckize, tidy, and extend a testcase to cover this case.

This fixes rdar://7527390.

71c25b7d7b Re-instate MOV64r0 and MOV16r0, with adjustments to work with the 
new AsmPrinter. This is perhaps less elegant than describing them
in terms of MOV32r0 and subreg operations, but it allows the
current register to rematerialize them.

7e0d64a49c Pattern top-level operators don't need to be restricted to a 
single user. The _su forms are intended for non-top-level nodes.

4b0345be30 Select an OR with immediate as an ADD if the input bits are known zero. This allow the instruction to be 3address-fied if needed.

95eb2eeea6 Implement a feature (-vector-unaligned-mem) to allow targets to 
ignore alignment requirements for SIMD memory operands.  This
is useful on architectures like the AMD 10h that do not trap on
unaligned references if a status bit is twiddled at startup time.

d686c8e73f "In order to ease automatic bindings generation, it would be helpful if boolean values were distinguishable from integers. The attached patch introduces "typedef int LLVMBool;", and uses LLVMBool instead of int throughout the C API, wherever a boolean value is called for."

a77169dbeb Fix http://llvm.org/PR5729: x86-64 tail calls were putting their targets into 
R11, and then asserting that the target was in R9.  Since R9 isn't reserved for
the target anymore, and is used as an argument, this patch changes the
assertion.

306b4cafc1 Fix a critical bug in 64-bit atomic operation lowering for 32-bit. The results of the cmpxchg8b instructions are being thrown away when it branches back to the top of the checking loop. This means the loop always compares against the old value and this can result in a dead lock.
