Chris Lattner 39f18e545e Teach codegen to lower llvm.powi to an efficient (but not optimal) 
multiply sequence when the power is a constant integer.  Before, our
codegen for std::pow(.., int) always turned into a libcall, which was
really inefficient.

This should also make many gfortran programs happier I'd imagine.

llvm-svn: 92388
 2010-01-01 03:32:16 +00:00
Chris Lattner 5967840a5f Make this more likely to generate a libcall.

Chris Lattner 8330daf733 add a few trivial instcombines for llvm.powi. 
llvm-svn: 92383
 2010-01-01 01:52:15 +00:00
Chris Lattner 71cf7c256f update this. To take the next step, llvm.powi should be generalized to work 
on integers as well and codegen should lower them to branch trees.

Chris Lattner 0c59ac3f41 When factoring multiply expressions across adds, factor both 
positive and negative forms of constants together.  This 
allows us to compile:

int foo(int x, int y) {
    return (x-y) + (x-y) + (x-y);
}

into:

_foo:                                                       ## @foo
	subl	%esi, %edi
	leal	(%rdi,%rdi,2), %eax
	ret

instead of (where the 3 and -3 were not factored):

_foo:
        imull   $-3, 8(%esp), %ecx
        imull   $3, 4(%esp), %eax
        addl    %ecx, %eax
        ret

this started out as:
    movl    12(%ebp), %ecx
    imull   $3, 8(%ebp), %eax
    subl    %ecx, %eax
    subl    %ecx, %eax
    subl    %ecx, %eax
    ret

This comes from PR5359.

Chris Lattner fed3397654 reuse negates where possible instead of always creating them from scratch. 
This allows us to optimize test12 into:

define i32 @test12(i32 %X) {
  %factor = mul i32 %X, -3                        ; <i32> [#uses=1]
  %Z = add i32 %factor, 6                         ; <i32> [#uses=1]
  ret i32 %Z
}

instead of:

define i32 @test12(i32 %X) {
  %Y = sub i32 6, %X                              ; <i32> [#uses=1]
  %C = sub i32 %Y, %X                             ; <i32> [#uses=1]
  %Z = sub i32 %C, %X                             ; <i32> [#uses=1]
  ret i32 %Z

Chris Lattner 9b493028df rename "elements" of metadata to "operands". "Elements" are

 2009-12-31 01:22:29 +00:00
Chris Lattner 8cb6c3476d Optimize MDNode to coallocate the operand list immediately 
after the MDNode in memory.  This eliminates the operands
pointer and saves a new[] per node.

Note that the code in DIDerivedType::replaceAllUsesWith is wrong
and quite scary.  A MDNode should not be RAUW'd with something
else: this changes all uses of the mdnode, which may not be debug
info related!  Debug info should use something non-mdnode for
declarations.

Chris Lattner 30ae06be14 do not bother reuniquing mdnodes whose operands drop to null. Doing 
so can be a huge performance issue when tearing down modules and mdnodes

Chris Lattner 94b9c5a73b now that instruction metadata is only parsed in one place, eliminate the

Chris Lattner 241264ee32 When doing v1->RAUW(v2), don't do anything to metadata. We don't know 
why one was replaced with the other.  Even in the specific case of 
debug information, it doesn't make sense to transfer the location over,
this will just result in jumbled loc info.

Chris Lattner b9c8651b8c add a layer of accessors around the Value::SubClassData member, and use 
a convention (shadowing the setter with private forwarding function) to
prevent subclasses from accidentally using it.

This exposed some bogosity in ConstantExprs, which was propaging the
opcode of the constant expr into the NUW/NSW/Exact field in the
getWithOperands/getWithOperandReplaced methods.

Chris Lattner 2f2aa2b067 This is a major cleanup of the instruction metadata interfaces that 
I asked Devang to do back on Sep 27.  Instead of going through the
MetadataContext class with methods like getMD() and getMDs(), just
ask the instruction directly for its metadata with getMetadata()
and getAllMetadata().

This includes a variety of other fixes and improvements: previously
all Value*'s were bloated because the HasMetadata bit was thrown into
value, adding a 9th bit to a byte.  Now this is properly sunk down to
the Instruction class (the only place where it makes sense) and it
will be folded away somewhere soon.

This also fixes some confusion in getMDs and its clients about 
whether the returned list is indexed by the MDID or densely packed.
This is now returned sorted and densely packed and the comments make
this clear.

This introduces a number of fixme's which I'll follow up on.
