llvm-svn: 37861
2007-07-03 23:04:11 +00:00
Owen Anderson b9a494aea3 Add functionality to value number GEP instructions. This also provides the infrastructure that will
be used for function calls.  NOTE: This does not yet do any transformation of GEPs or function calls.

Owen Anderson fc56043844 Remove BFtoLLVM. It was old, and a poor example because it didn't use best practices for making
a LLVM frontend in C++.  Maybe someday it will be rewritten..

Owen Anderson 6b958c72bd Make the unary operator case a bit faster, since casts are the only kind of unary operation.
llvm-svn: 37857
2007-07-03 19:01:42 +00:00
Owen Anderson 59bd053fc5 Add support for performing GVNPRE on cast instructions, and add a testcase for this.

2007-07-03 18:37:08 +00:00
Tanya Lattner 11f9d1b7ee 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.
llvm-svn: 37855

Anton Korobeynikov 510dfdaa0d Revert last change until issue reported by Owen, won't be fixed.

Dale Johannesen a8bf39ee31 New testcases for rev 37847 (PR's 1489 and 1505).
llvm-svn: 37848
2007-07-03 00:58:37 +00:00
Dale Johannesen a2b3c175db Fix for PR 1505 (and 1489). Rewrite X87 register
model to include f32 variants.  Some factoring
improvments forthcoming.

llvm-svn: 37846
2007-07-02 18:10:52 +00:00
Dan Gohman 9ff9908413 Add a basic test-case for passing and returning <4 x double> and
<8 x float> values on X86.

llvm-svn: 37845
2007-07-02 16:23:47 +00:00
Dan Gohman f9ae1c6001 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.

llvm-svn: 37844
2007-07-02 16:21:53 +00:00
Dan Gohman 533dd16a7f 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.

llvm-svn: 37843
2007-07-02 16:18:06 +00:00
Dan Gohman 9a70823375 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.

llvm-svn: 37842
2007-07-02 15:48:56 +00:00
Dan Gohman 11a4008a59 New test case. DAGCombiner should be able to fold -sin(-x)
in -enable-unsafe-fp-math mode.

llvm-svn: 37841
2007-07-02 15:43:20 +00:00
Dan Gohman 32c3c19bed Remove declarations for code no longer in the tree, to avoid confusion.
