Evan Cheng f3e9a48584 Enable machine sinking critical edge splitting. e.g. 
define double @foo(double %x, double %y, i1 %c) nounwind {
  %a = fdiv double %x, 3.2
  %z = select i1 %c, double %a, double %y
  ret double %z
}

Was:
_foo:
        divsd   LCPI0_0(%rip), %xmm0
        testb   $1, %dil
        jne     LBB0_2
        movaps  %xmm1, %xmm0
LBB0_2:
        ret

Now:
_foo:
        testb   $1, %dil
        je      LBB0_2
        divsd   LCPI0_0(%rip), %xmm0
        ret
LBB0_2:
        movaps  %xmm1, %xmm0
        ret

This avoids the divsd when early exit is taken.

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.

Bruno Cardoso Lopes 4713b282ce - Add sugregister logic to handle f64=(f32,f32). 
- Support mips1 like load/store of doubles:

Instead of:
  sdc $f0, X($3)
Generate:
  swc $f0, X($3)
  swc $f1, X+4($3)

Bruno Cardoso Lopes 537e409c58 - Fix a small bug while handling target constant pools (one param was missing). 
- Add a smarter constant pool loading, instead of:

lui $2, %hi($CPI1_0)
addiu $2, $2, %lo($CPI1_0)
lwc1 $f0, 0($2)

Generate:

lui $2, %hi($CPI1_0)

Chris Lattner 68535f7603 reintroduce support for Mips "small" section handling. This is 
implemented somewhat differently than before, but it should have
the same functionality and the previous testcase passes again.

Daniel Dunbar 0f16ea5c30 Pass target triple string in to TargetMachine constructor. 
This is not just a matter of passing in the target triple from the module;
currently backends are making decisions based on the build and host
architecture. The goal is to migrate to making these decisions based off of the
triple (in conjunction with the feature string). Thus most clients pass in the
target triple, or the host triple if that is empty.

This has one important change in the way behavior of the JIT and llc.

For the JIT, it was previously selecting the Target based on the host
(naturally), but it was setting the target machine features based on the triple
from the module. Now it is setting the target machine features based on the
triple of the host.

For LLC, -march was previously only used to select the target, the target
machine features were initialized from the module's triple (which may have been
empty). Now the target triple is taken from the module, or the host's triple is
used if that is empty. Then the triple is adjusted to match -march.

The take away is that -march for llc is now used in conjunction with the host
triple to initialize the subtarget. If users want more deterministic behavior
from llc, they should use -mtriple, or set the triple in the input module.

Duncan Sands 0cf7f5d6d2 Revert commit 76707, it was breaking the llvm-gcc build 
on linux platforms.  The binutils assembler does not
recognize the "s" flag, see for example

updating a mips testcase to expect it.

Dan Gohman a5b9645c4b Split the Add, Sub, and Mul instruction opcodes into separate 
integer and floating-point opcodes, introducing
FAdd, FSub, and FMul.

For now, the AsmParser, BitcodeReader, and IRBuilder all preserve
backwards compatability, and the Core LLVM APIs preserve backwards
compatibility for IR producers. Most front-ends won't need to change
immediately.

This implements the first step of the plan outlined here:

Dan Gohman 1407484178 The list-td and list-tdrr schedulers don't yet support physreg 
scheduling dependencies. Add assertion checks to help catch
this.

It appears the Mips target defaults to list-td, and it has a
regression test that uses a physreg dependence. Such code was
liable to be miscompiled, and now evokes an assertion failure.
