Dan Gohman 7867793aff Add new TargetLowering code to provide the final register type that an 
illegal value type will be transformed to, for code that needs the
register type after all transformations instead of just after the first
transformation.

Factor out the code that uses this information to do copy-from-regs and
copy-to-regs for various purposes into separate functions so that they
are done consistently.

Lauro Ramos Venancio b2c3a67015 Fix a bug in my previous patch. 
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.

Owen Anderson 7dae8efcf2 Use cached information that has already been computed to make clean() simpler and faster. This is a small speedup on most cases.

Dan Gohman 7139a48057 Use getVectorTypeBreakdown in FunctionLoweringInfo::CreateRegForValue
