a43a3f2379 When doing v1->RAUW(v2), don't do anything to metadata. We don't know 
why one was replaced with the other.  Even in the specific case of 
debug information, it doesn't make sense to transfer the location over,
this will just result in jumbled loc info.

cafe9bba32 add a layer of accessors around the Value::SubClassData member, and use 
a convention (shadowing the setter with private forwarding function) to
prevent subclasses from accidentally using it.

This exposed some bogosity in ConstantExprs, which was propaging the
opcode of the constant expr into the NUW/NSW/Exact field in the
getWithOperands/getWithOperandReplaced methods.

3990b121cf This is a major cleanup of the instruction metadata interfaces that 
I asked Devang to do back on Sep 27.  Instead of going through the
MetadataContext class with methods like getMD() and getMDs(), just
ask the instruction directly for its metadata with getMetadata()
and getAllMetadata().

This includes a variety of other fixes and improvements: previously
all Value*'s were bloated because the HasMetadata bit was thrown into
value, adding a 9th bit to a byte.  Now this is properly sunk down to
the Instruction class (the only place where it makes sense) and it
will be folded away somewhere soon.

This also fixes some confusion in getMDs and its clients about 
whether the returned list is indexed by the MDID or densely packed.
This is now returned sorted and densely packed and the comments make
this clear.

This introduces a number of fixme's which I'll follow up on.

b241b37031 Rewrite the function-local validation logic for MDNodes (most of r91708). 
Among other benefits, this doesn't leak the SmallPtrSet, has the verifier
code in the verifier pass, actually does the verification at the end,
and is considerably simpler.

003a09c68d Substantially optimize APFloat::toString() by doing a single large divide to 
cut the significand down to the desired precision *before* entering the
core divmod loop.  Makes the overall algorithm logarithmic in the exponent.

There's still a lot of room for improvement here, but this gets the
performance back down to acceptable-for-diagnostics levels, even for
long doubles.
negligible, even on long doubles.

04b091a782 handle equality memcmp of 8 bytes on x86-64 with two unaligned loads and a 
compare.  On other targets we end up with a call to memcmp because we don't
want 16 individual byte loads.  We should be able to use movups as well, but
we're failing to select the generated icmp.

8047d9a6be move an optimization for memcmp out of simplifylibcalls and into 
SDISel.  This optimization was causing simplifylibcalls to 
introduce type-unsafe nastiness.  This is the first step, I'll be 
expanding the memcmp optimizations shortly, covering things that
we really really wouldn't want simplifylibcalls to do.

0f706ab789 Move the extern symbol declarations outside of 
DynamicLibrary::SearchForAddressOfSymbol and force them to have "C"
linkage. 

Interestingly, GCC treats the block-scoped "extern" declarations we
previously had as if they were extern "C" declarations (or, at least,
were in the global namespace), so that GCC bug papered over this LLVM
bug. Clang and EDG get the linkage correct; this new variant seems to
work for both GCC and Clang.

b5d568cc70 Provide dbgs(), a circular-buffering debug output stream. By default it 
simply passes output to errs().  If -debug-buffer-size=N is set N > 0,
dbgs() buffers its output until program termination and dumps the last N
characters sent to it.  This is handy when debugging very large inputs.

e59011e7d9 Add circular_raw_ostream, which buffers its output in a circular queue

situations such as debug output logging where a signal handler can take
care of flushing the buffer at program termination.

6a38182471 stop pattern matching 16-bit zero's of a register to MOV16r0, 
instead use the appropriate subreggy thing.  This generates identical
code on some large apps (thanks to Evan's cross class coalescing
stuff he did back in july).  This means that MOV16r0 can go away
completely in the future soon.

c5818fb837 Partially revert r91626. Materializing extra functions to determine whether 
they're available_externally broke VMKit, which was relying on the fact that
functions would only be materialized when they were first called.  We'll have
to wait for http://llvm.org/PR5737 to really fix this.

I also added a test for one of the F->isDeclaration() calls which wasn't
covered by anything else in the test suite.

aadadb3973 Fix the Convert to scalar to not insert dead loads in the store case. The 
load is needed when we have a small store into a large alloca (at which 
point we get a load/insert/store sequence), but when you do a full-sized
store, this load ends up being dead.

This dead load is bad in really large nasty testcases where the load ends
up causing mem2reg to insert large chains of dependent phi nodes which only
ADCE can delete.  Instead of doing this, just don't insert the dead load.

This fixes rdar://6864035

3cf4d90f3d revert r89298, which was committed without a testcase. I think 
the underlying PHI node insertion issue in SSAUpdate is fixed.

4c1e3da0cd fix PR5837 by having SSAUpdate reuse phi nodes for the 
'GetValueInMiddleOfBlock' case, instead of inserting 
duplicates.

A similar fix is almost certainly needed by the machine-level
SSAUpdate implementation.

b109b5c148 give instcombine some helper functions for matching MIN and MAX, and 
implement some optimizations for MIN(MIN()) and MAX(MAX()) and 
MIN(MAX()) etc.  This substantially improves the code in PR5822 but
doesn't kick in much elsewhere.  2 max's were optimized in 
pairlocalalign and one in smg2000.

3bf6815556 enhance x-(-A) -> x+A to preserve NUW/NSW. 
Use the presence of NSW/NUW to fold "icmp (x+cst), x" to a constant in
cases where it would otherwise be undefined behavior.

Surprisingly (to me at least), this triggers hundreds of the times in
a few benchmarks: lencode, ldecode, and 466.h264ref seem to *really*
like this.

8ed9f51663 Table-driven disassembler for the X86 architecture (16-, 32-, and 64-bit 
incarnations), integrated into the MC framework.  

The disassembler is table-driven, using a custom TableGen backend to 
generate hierarchical tables optimized for fast decode.  The disassembler 
consumes MemoryObjects and produces arrays of MCInsts, adhering to the 
abstract base class MCDisassembler (llvm/MC/MCDisassembler.h).

The disassembler is documented in detail in

- lib/Target/X86/Disassembler/X86Disassembler.cpp (disassembler runtime)
- utils/TableGen/DisassemblerEmitter.cpp (table emitter)

You can test the disassembler by running llvm-mc -disassemble for i386
or x86_64 targets.  Please let me know if you encounter any problems
with it.

- function-localness is designated via lowest bit in SubclassData
- getLocalFunction() descends MDNode tree to see if it is consistently function-local

Add verification of MDNodes to checks that MDNodes are consistently function-local.

fda60d35c2 Fix libstdc++ build on ARM linux and part of PR5770. 
MI was not being used but it was also not being deleted, so it was kept in the garbage list. The memory itself was freed once the function code gen was done.

Once in a while the codegen of another function would create an instruction on the same address. Adding it to the garbage group would work once, but when another pointer was added it would cause an assert as "Cache" was about to be pushed to Ts.

For a patch that make us detect problems like this earlier, take a look at

http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20091214/092758.html

With that patch we assert as soon and the new instruction is added to the garbage set.

400073d546 On recent Intel u-arch's, folding loads into some unary SSE instructions can 
be non-optimal. To be precise, we should avoid folding loads if the instructions
only update part of the destination register, and the non-updated part is not
needed. e.g. cvtss2sd, sqrtss. Unfolding the load from these instructions breaks
the partial register dependency and it can improve performance. e.g.

movss (%rdi), %xmm0
cvtss2sd %xmm0, %xmm0

instead of
cvtss2sd (%rdi), %xmm0

An alternative method to break dependency is to clear the register first. e.g.
xorps %xmm0, %xmm0
cvtss2sd (%rdi), %xmm0

c226fe3c3e Pass the error string directly to llvm_unreachable instead of the residual 
(0 && "error").  Rough consensus seems to be that g++ *should* be diagnosing
this because the pointer makes it not an ICE in c++03.  Everyone agrees that
the current standard is silly and null-pointer-ness should not be based on
ICE-ness.  Excellent fight scene in Act II, denouement weak, two stars.

108934c65d Instruction fixes, added instructions, and AsmString changes in the 
X86 instruction tables.

Also (while I was at it) cleaned up the X86 tables, removing tabs and
80-line violations.

This patch was reviewed by Chris Lattner, but please let me know if
there are any problems.

* X86*.td
	Removed tabs and fixed 80-line violations

* X86Instr64bit.td
	(IRET, POPCNT, BT_, LSL, SWPGS, PUSH_S, POP_S, L_S, SMSW)
		Added
	(CALL, CMOV) Added qualifiers
	(JMP) Added PC-relative jump instruction
	(POPFQ/PUSHFQ) Added qualifiers; renamed PUSHFQ to indicate
		that it is 64-bit only (ambiguous since it has no
		REX prefix)
	(MOV) Added rr form going the other way, which is encoded
		differently
	(MOV) Changed immediates to offsets, which is more correct;
		also fixed MOV64o64a to have to a 64-bit offset
	(MOV) Fixed qualifiers
	(MOV) Added debug-register and condition-register moves
	(MOVZX) Added more forms
	(ADC, SUB, SBB, AND, OR, XOR) Added reverse forms, which

	(XADD, CMPXCHG, XCHG) Added non-locked forms
* X86InstrSSE.td
	(CVTSS2SI, COMISS, CVTTPS2DQ, CVTPS2PD, CVTPD2PS, MOVQ)

3de8249078 Turn off critical edge splitting for landing pads. The introduction of a 
non-landing pad basic block as the successor to a block that ends in an
unconditional jump will cause block folding to remove the added block as a
successor. Thus eventually removing it AND the landing pad entirely. Critical
edge splitting is an optimization, so we can safely turn it off when dealing
with landing pads.

0c826d98b3 Slightly generalize transformation of memmove(a,a,n) so that it also applies 
to memcpy. (Such a memcpy is technically illegal, but in practice is safe
and is generated by struct self-assignment in C code.)

bceddbdc91 Introduce EVT::getHalfSizedIntegerVT() for use in ExpandUnalignedStore() in 
LegalizeDAG.cpp. Unlike the code it replaces, which simply decrements the simple
type by one, getHalfSizedIntegerVT() searches for the smallest simple integer
type that is at least half the size of the type it is called on. This approach
has the advantage that it will continue working if a new value type (such as
i24) is added to MVT.

Also, in preparation for new value types, remove the assertions that
non-power-of-2 8-bit-mutiple types are Extended when legalizing extload and
truncstore operations.

70d0ef1459 In LowerEXTRACT_VECTOR_ELT, force an i32 value type for PEXTWR instead of 
incrementing the simple value type of the 16-bit type, which would give the
wrong type if an intemediate MVT (such as i24) were introduced.
