Jakob Stoklund Olesen ad89613b65 Only collect subreg extracting copies for later coalescing.
This also avoids fatal copies from physregs.

Dan Gohman a64a323564 Fix a bug in the code which re-inserts DBG_VALUE nodes after scheduling;
if a block is split (by a custom inserter), the insert point may be in a
different block than it was originally. This fixes 32-bit llvm-gcc
bootstrap builds, and I haven't been able to reproduce it otherwise.

Duncan Sands 82b21c086e The accumulator tail recursion transform claims to work for any associative
operation, but the way it's implemented requires the operation to also be
commutative.  So add a check for commutativity (and tweak the corresponding
comments).  This makes no difference in practice since every associative
LLVM instruction is also commutative!  Here's an example to show the need
for commutativity: the accum_recursion.ll testcase calculates the factorial
function.  Before the transformation the result of a call is
  ((((1*1)*2)*3)...)*x
while afterwards it is
  (((1*x)*(x-1))...*2)*1
which clearly requires both associativity and commutativity of * to be equal
to the original.

Nick Lewycky d54e2aba6c PrintFunctionNames is a plugin, it should pull in symbols from the clang binary

Jakob Stoklund Olesen e50d30d586 Emit COPY instructions instead of using copyRegToReg in InstrEmitter,
ScheduleDAGEmit, TwoAddressLowering, and PHIElimination.

This switches the bulk of register copies to using COPY, but many less used
copyRegToReg calls remain.

Jakob Stoklund Olesen de457896b6 Don't emit st(0)/st(1) copies as FpMOV instructions. Use FpSET_ST? instead.
Based on a patch by Rafael Espíndola.

Attempt to make the FpSET_ST1 hack more robust, but we are still relying on
FpSET_ST0 preceeding it. This is only for supporting really weird x87 inline
asm.

We support:

  FpSET_ST0
  INLINEASM

  FpSET_ST0
  FpSET_ST1
  INLINEASM

with and without kills on the arguments. We don't support:

  FpSET_ST1
  FpSET_ST0
  INLINEASM

nor

  FpSET_ST1
  INLINEASM

Just Don't Do It!

Chandler Carruth 17773fcd83 Lay the ground work for resoving PR7047. This doesn't actually fix it because
default arguments to template parameters don't have a DeclContext when
instantiated, and so we can't detect that we're in an instantiation context as
opposed to the definition context. However, it fixes the more commonly-occuring
cases in TMP code that use devolve to this type of tautology after
substitution.

Dan Gohman d7b5ce3312 Reapply bottom-up fast-isel, with several fixes for x86-32:
- Check getBytesToPopOnReturn().
 - Eschew ST0 and ST1 for return values.
 - Fix the PIC base register initialization so that it doesn't ever
   fail to end up the top of the entry block.

Jakob Stoklund Olesen be8d9b0bb8 An x86 function returns a floating point value in st(0), and we must make sure
it is popped, even if it is ununsed. A CopyFromReg node is too weak to represent
the required sideeffect, so insert an FpGET_ST0 instruction directly instead.

This will matter when CopyFromReg gets lowered to a generic COPY instruction.

Jim Ingham a56c800607 Add an "Avoid Frames matching this regular expression" to ThreadPlanStepInRange.
This relies on ThreadPlanStepOut working correctly, which it doesn't currently for Inlined functions, so this feature is only partially useful until we take care of Stepping Out of inlined functions.
Added an option to "thread step-in" to set the avoid regular expression.  This is mostly for testing, once the Setting code is redone, we'll move this to a general setting.

Craig Silverstein 4a5d086b50 Fix a crashing but trying to print a TemplateTemplateParmDecl
for code like this:
   template<template<typename T> class U> class V {};

The problem is that the DeclPrinter assumed all TemplateDecls
have a getTemplatedClass(), but template template params don't
(so we got a NULL dereference).  The solution is to detect if
we're a template template param, and construct the template
class name ('class U') specially in this case.
