778ad67a26 Make the unary operator case a bit faster, since casts are the only kind of unary operation.

ba084e17fd Add support for performing GVNPRE on cast instructions, and add a testcase for this.

cbbc232425 We really should not have this version number in SO many makefiles. This should also probably change to svn instead of cvs, but leaving it for now.

7af19491d3 Fix for PR 1505 (and 1489). Rewrite X87 register 
model to include f32 variants.  Some factoring
improvments forthcoming.

965e6efe24 Add a basic test-case for passing and returning <4 x double> and 
<8 x float> values on X86.

eb46e6e629 Vector results may be returned in XMM0 and XMM1, not just XMM0. With 
the recent lowering changes, this allows types like <4 x double> to
be returned, using two vector registers.

68f0cbccfb Replace ExpandScalarFormalArgs and ExpandScalarCallArgs with the newly 
refactored getCopyFromParts and getCopyToParts, which are more general.
This effectively adds support for lowering illegal by-val vector call
arguments.

5fe8266d04 Teach GetNegatedExpression to negate 0-B to B in UnsafeFPMath mode, and 
visitFSUB to fold 0-B to -B in UnsafeFPMath mode. Also change visitFNEG
to use isNegatibleForFree/GetNegatedExpression instead of doing a subset
of the same thing manually.

This fixes test/CodeGen/X86/negative-sin.ll.
