Chris Lattner de9046af54 Implement splitting support for store, allowing us to compile: 
%f8 = type <8 x float>

define void @test_f8(%f8* %P, %f8* %Q, %f8* %S) {
	%p = load %f8* %P		; <%f8> [#uses=1]
	%q = load %f8* %Q		; <%f8> [#uses=1]
	%R = add %f8 %p, %q		; <%f8> [#uses=1]
	store %f8 %R, %f8* %S
	ret void
}

into:

_test_f8:
	movaps	16(%rdi), %xmm0
	addps	16(%rsi), %xmm0
	movaps	(%rdi), %xmm1
	addps	(%rsi), %xmm1
	movaps	%xmm0, 16(%rdx)
	movaps	%xmm1, (%rdx)
	ret

Chris Lattner f47015bc74 Fix a significant code quality regression I introduced on PPC64 quite 
a while ago.  We now produce:

_foo:
	mflr r0
	std r0, 16(r1)
	ld r2, 16(r1)
	std r2, 0(r3)
	ld r0, 16(r1)
	mtlr r0
	blr 

instead of:

_foo:
	mflr r0
	std r0, 16(r1)
	lis r0, 0
	ori r0, r0, 16
	ldx r2, r1, r0
	std r2, 0(r3)
	ld r0, 16(r1)
	mtlr r0
	blr 

for:

void foo(void **X) {
  *X = __builtin_return_address(0);
}

on ppc64.

Chris Lattner eedaf92fcf third time around: instead of disabling this completely, 
only disable it if we don't know it will be obviously profitable.
Still fixme, but less so. :)

 2007-12-06 07:47:55 +00:00
Chris Lattner b5fdfb9612 Actually, disable this code for now. More analysis and improvements to 
the X86 backend are needed before this should be enabled by default.

llvm-svn: 44657
 2007-12-06 07:44:31 +00:00
Chris Lattner 7c709a5d08 implement a readme entry, compiling the code into: 
_foo:
	movl	$12, %eax
	andl	4(%esp), %eax
	movl	_array(%eax), %eax
	ret

instead of:

_foo:
	movl	4(%esp), %eax
	shrl	$2, %eax
	andl	$3, %eax
	movl	_array(,%eax,4), %eax
	ret

As it turns out, this triggers all the time, in a wide variety of
situations, for example, I see diffs like this in various programs:

-       movl    8(%eax), %eax
-       shll    $2, %eax
-       andl    $1020, %eax
-       movl    (%esi,%eax), %eax
+       movzbl  8(%eax), %eax
+       movl    (%esi,%eax,4), %eax


-       shll    $2, %edx
-       andl    $1020, %edx
-       movl    (%edi,%edx), %edx
+       andl    $255, %edx
+       movl    (%edi,%edx,4), %edx

Unfortunately, I also see stuff like this, which can be fixed in the
X86 backend:

-       andl    $85, %ebx
-       addl    _bit_count(,%ebx,4), %ebp
+       shll    $2, %ebx
+       andl    $340, %ebx
+       addl    _bit_count(%ebx), %ebp

Evan Cheng 269dbd31d0 - Mark last use of a split interval as kill instead of letting spiller track it. 
This allows an important optimization to be re-enabled.
- If all uses / defs of a split interval can be folded, give the interval a
  low spill weight so it would not be picked in case spilling is needed (avoid
  pushing other intervals in the same BB to be spilled).

Gordon Henriksen 363b02003b Track dependencies when creating symlinks to LLVM libraries next 
to the ocaml bindings. This is required on Windows where 'ln -sf'
actually creates a copy. Thanks to Alain Frisch for noticing this.

Duncan Sands 38ef3a8ec7 Rather than having special rules like "intrinsics cannot 
throw exceptions", just mark intrinsics with the nounwind
attribute.  Likewise, mark intrinsics as readnone/readonly
and get rid of special aliasing logic (which didn't use
anything more than this anyway).

Duncan Sands 68b6f50938 Integrate the readonly/readnone logic more deeply 
into alias analysis.  This meant updating the API
which now has versions of the getModRefBehavior,
doesNotAccessMemory and onlyReadsMemory methods
which take a callsite parameter.  These should be
used unless the callsite is not known, since in
general they can do a better job than the versions
that take a function.  Also, users should no longer
call the version of getModRefBehavior that takes
both a function and a callsite.  To reduce the
chance of misuse it is now protected.

Evan Cheng 8494ee175c Fix a major performance issue with splitting. If there is a def (not def/use) 
in the middle of a split basic block, create a new live interval starting at
the def. This avoid artifically extending the live interval over a number of
cycles where it is dead. e.g.

bb1:
       = vr1204   (use / kill) <= new interval starts and ends here.
...
...
vr1204 =          (new def)   <= start a new interval here.
       = vr1204   (use)
