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

llvm-svn: 37778
 2007-06-28 20:06:38 +00:00
David Greene cbc8ddf81a Add support for building with _GLIBCXX_DEBUG. New configure option 
--enable-expensive-checks allows the developer to enable runtime
checking that can greatly increase compile time.  Currently it only
turns on _GLIBCXX_DEBUG.  Other expensive debugging checks added later
should be controlled by this configure option.

This patch also updates llvm-config with a --cppflags option to inform
llvm-gcc how to build itself so that it is compatible with an llvm that
was built with _GLIBCXX_DEBUG.

Dan Gohman a866514528 Generalize MVT::ValueType and associated functions to be able to represent 
extended vector types. Remove the special SDNode opcodes used for pre-legalize
vector operations, and the special MVT::Vector type used with them. Adjust
lowering and legalize to work with the normal SDNode kinds instead, and to
use the normal MVT functions to work with vector types instead of using the
two special operands that the pre-legalize nodes held.

This allows pre-legalize and post-legalize DAGs, and the code that operates
on them, to be more consistent. Pre-legalize vector operators can be handled
more consistently with scalar operators. And, -view-dag-combine1-dags and
-view-legalize-dags now look prettier for vector code.
