f58d4dec98 Oops, can't unwind to the entry block (entry block may have no preds).

fc82fabe00 Add an unwind_to field to basic blocks, making them Users instead of Values. 
This is the first checkin for PR1269, the new EH infrastructure.

that instruction as its "last use". This fixes PR1925.

9d34c4d678 fix a bug Anders ran into where scalarrepl would crash when promoting 
a union containing a vector and an array whose elements were smaller than
the vector elements.  this means we need to compile the load of the 
array elements into an extract element plus a truncate.

b09916bdfb Make X86TargetLowering::LowerSINT_TO_FP return without creating a dead 
stack slot and store if the  SINT_TO_FP is actually legal.  This allows
us to compile:

double a(double b) {return (unsigned)b;}

to:

_a:
	cvttsd2siq	%xmm0, %rax
	movl	%eax, %eax
	cvtsi2sdq	%rax, %xmm0
	ret

instead of:

_a:
	subq	$8, %rsp
	cvttsd2siq	%xmm0, %rax
	movl	%eax, %eax
	cvtsi2sdq	%rax, %xmm0
	addq	$8, %rsp
	ret

crazy.

d0ba2a9c14 Compile x86-64-and-mask.ll into: 
_test:
	movl	%edi, %eax
	ret

instead of:

_test:
        movl    $4294967295, %ecx
        movq    %rdi, %rax
        andq    %rcx, %rax
        ret

It would be great to write this as a Pat pattern that used subregs 
instead of a 'pseudo' instruction, but I don't know how to do that
in td files.

684ed3d987 While hunting for two hanging tests, 
(on solaris10, which are:
  CodeGen/PowerPC/frounds.ll
  Transforms/InstCombine/2008-02-23-MulSub.ll)

I needed a tool to figure out which one is the guilty.

To this end I have added a verbosity
option to the test/Makefile.

It can be invoked thus:

gmake check TESTSUITE=CodeGen/PowerPC VERBOSE="-v -v"

(The number of "-v"s specifies the verbosity level.
 Instead of "-v" other aliases can be specified,
 please consult the dejagnu docs for info.)

At level >= 2 following line is logged for each
test, before running it:

ABOUT TO RUN: <test>.ll

c886c460e4 This is possible: 
vr1 = extract_subreg vr2, 3
...
vr3 = extract_subreg vr1, 2
The end result is vr3 is equal to vr2 with subidx 2.

0254e7033a Fix isNegatibleForFree to not return true for ConstantFP nodes 
after legalize.  Just because a constant is legal (e.g. 0.0 in SSE) 
doesn't mean that its negated value is legal (-0.0).  We could make
this stronger by checking to see if the negated constant is actually
legal post negation, but it doesn't seem like a big deal.

a59d469e9b Merge current work back to tree to minimize diffs and drift. Major highlights 
for CellSPU modifications:

- SPUInstrInfo.td refactoring: "multiclass" really is _your_ friend.
- Other improvements based on refactoring effort in SPUISelLowering.cpp,
  esp. in SPUISelLowering::PerformDAGCombine(), where zero amount shifts and
  rotates are now eliminiated, other scalar-to-vector-to-scalar silliness
  is also eliminated.
- 64-bit operations are being implemented, _muldi3.c gcc runtime now
  compiles and generates the right code. More work still needs to be done.
