869b2b2c23 Move the entries for 64-bit CMP, IMUL, and a few others into the correct 
tables so that they are eligible for reload/remat folding. And add
entries for JMP and CALL.

ca8035e356 Remove RSTRegClass case from loadRegFromStackSlot 
and storeRegToStackSlot.  Evan and I concluded this
should never be needed and it appears to be true.
(It if is needed, adjustment would be needed for
long double to work.)

5bda9e49ec Fix PR1666, SPASS with the CBE and 254.gap with the CBE. 
GCC optimizes away things like ptr < NULL  to false.  To "fix" this,
have the CBE emit casts of pointers to intptr_t when doing relational
pointer comparisons.

9e3d3abd93 Remove the assumption that FP's are either float or 
double from some of the many places in the optimizers
it appears, and do something reasonable with x86
long double.
Make APInt::dump() public, remove newline, use it to
dump ConstantSDNode's.
Allow APFloats in FoldingSet.
Expand X86 backend handling of long doubles (conversions
to/from int, mostly).

85dbe1a1d2 Initial support for multi-result patterns: 
1.
[(set GR32:$dst, (add GR32:$src1, GR32:$src2)),
 (modify EFLAGS)]
This indicates the source pattern expects the instruction would produce 2 values. The first is the result of the addition. The second is an implicit definition in register EFLAGS.
2.
def : Pat<(parallel (addc GR32:$src1, GR32:$src2), (modify EFLAGS)), ()>
Similar to #1 except this is used for def : Pat patterns.

b0869ed44d It's not safe to rematerialize MOV32r0 etc. by simply cloning the original 
instruction. These are implemented with xor which will modify the conditional
code. They should be rematerialized as move instructions.

Use APFloat in UpgradeParser and AsmParser.
Change all references to ConstantFP to use the
APFloat interface rather than double.  Remove

(There are still way too many places APFloat is
just a wrapper around host float/double, but we're
getting there.)

6994040a95 This is the patch to provide clean intrinsic function overloading support in LLVM. It cleans up the intrinsic definitions and generally smooths the process for more complicated intrinsic writing. It will be used by the upcoming atomic intrinsics as well as vector and float intrinsics in the future. 
This also changes the syntax for llvm.bswap, llvm.part.set, llvm.part.select, and llvm.ct* intrinsics. They are automatically upgraded by both the LLVM ASM reader and the bitcode reader. The test cases have been updated, with special tests added to ensure the automatic upgrading is supported.

73a902b228 Mark the SSE and MMX load instructions that 
X86InstrInfo::isReallyTriviallyReMaterializable knows how to handle
with the isReMaterializable flag so that it is given a chance to handle
them. Without hoisting constant-pool loads from loops this isn't very
visible, though it does keep CodeGen/X86/constant-pool-remat-0.ll from
making a copy of the constant pool on the stack.

b1576f56c8 Change the x86 assembly output to use tab characters to separate the 
mnemonics from their operands instead of single spaces. This makes the
assembly output a little more consistent with various other compilers
(f.e. GCC), and slightly easier to read. Also, update the regression
tests accordingly.

d300622eba Re-apply 40504, but with a fix for the segfault it caused in oggenc: 
Make the alignedload and alignedstore patterns always require 16-byte
alignment. This way when they are used in the "Fs" instructions, in which
a vector instruction is used for a scalar purpose, they can still require
the full vector alignment. And add a regression test for this.
