97135e1ee5 Factor out the code for determining when symblic addresses 
require RIP-relative addressing and use it to fix a bug
in X86FastISel in x86-64 PIC mode, where it was trying to
use base/index registers with RIP-relative addresses. This
fixes a bunch of x86-64 testsuite failures.

d751c64a67 If we have a function with an unreachable statement such that the ending debug 
information is in an unreachable block, then it's possible that the high/low pc
values won't be set for the dwarf information. E.g., this function:

void abort(void) __attribute__((__noreturn__));
void dead_beef(void) __attribute__ ((noreturn));

int *b;

void dead_beef(void) {
  *b=0xdeadbeef;
  abort();
}

has a call to "@llvm.dbg.region.end" only in the unreachable block:

define void @dead_beef() noreturn nounwind  {
entry:
	call void @llvm.dbg.func.start(...)
	call void @llvm.dbg.stoppoint(...)
...
	call void @abort( ) noreturn nounwind 
	unreachable

return:		; No predecessors!
	call void @llvm.dbg.stoppoint(...)
	call void @llvm.dbg.region.end(...)
	ret void
}

The dwarf information emitted is something like:

0x00000084:     TAG_subprogram [5]  
                 AT_name( "dead_beef" )
                 AT_external( 0x01 )
                 AT_prototyped( 0x01 )
                 AT_decl_file( 0x01 )
                 AT_decl_line( 0x08 )

Note that this is *not* the best fix for this problem, but a band-aid for an
gaping wound. This code needs to be changed when we revamp our debugging
information.

0598866c05 Large mechanical patch. 
s/ParamAttr/Attribute/g
s/PAList/AttrList/g
s/FnAttributeWithIndex/AttributeWithIndex/g
s/FnAttr/Attribute/g

This sets the stage 
- to implement function notes as function attributes and 
- to distinguish between function attributes and return value attributes.

This requires corresponding changes in llvm-gcc and clang.

b5b6ec6488 FastISel: For calls, prefer using the callee's address as a constant 
over having it in a register. And wait until after checking type
legality before requesting that the callee address be placed in a
register. Also, fix support for calls with void return type.

This speeds up fast-isel isel time by about 15% and reduces
instruction counts by about 3% overall on certain testcases. It also
changes many indirect calls to direct calls.

095cc29f32 Define CallSDNode, an SDNode subclass for use with ISD::CALL. 
Currently it just holds the calling convention and flags
for isVarArgs and isTailCall.

And it has several utility methods, which eliminate magic
5+2*i and similar index computations in several places.

CallSDNodes are not CSE'd. Teach UpdateNodeOperands to handle
nodes that are not CSE'd gracefully.

d18a462bdd The version of AtomicSDNode::AtomicSDNode used (only) for 
cmp-and-swap reversed the Cmp and Swap arguments; comments
make it clear this is unintentional.  Unfortunately, the

PPC is OK.

From inspection of the Alpha code I think it is OK, but
if somebody has that platform please check it out.  I
cannot test on that platform.

4a03775777 For whatever the reason, x86 CallingConv::Fast (i.e. fastcc) was not passing scalar arguments in registers. This patch defines a new fastcc CC which is slightly different from the FastCall CC. In addition to passing integer arguments in ECX and EDX, it also specify doubles are passed in 8-byte slots which are 8-byte aligned (instead of 4-byte aligned). This avoids a potential performance hazard where doubles span cacheline boundaries.

3df24e667f Create HandlePHINodesInSuccessorBlocksFast, a version of 
HandlePHINodesInSuccessorBlocks that works FastISel-style. This
allows PHI nodes to be updated correctly while using FastISel.

This also involves some code reorganization; ValueMap and
MBBMap are now members of the FastISel class, so they needn't
be passed around explicitly anymore. Also, SelectInstructions
is changed to SelectInstruction, and only does one instruction
at a time.

e00a8a2a2e Split the ATOMIC NodeType's to include the size, e.g. 
ATOMIC_LOAD_ADD_{8,16,32,64} instead of ATOMIC_LOAD_ADD.
Increased the Hardcoded Constant OpActionsCapacity to match.
Large but boring; no functional change.

This is to support partial-word atomics on ppc; i8 is
not a valid type there, so by the time we get to lowering, the
ATOMIC_LOAD nodes looks the same whether the type was i8 or i32.
The information can be added to the AtomicSDNode, but that is the
largest SDNode; I don't fully understand the SDNode allocation,
but it is sensitive to the largest node size, so increasing
that must be bad.  This is the alternative.
