Always check the type of node. This prevents situations such as selecting 32-bit rotate target instruction for a 64-bit node when 64-bit pattern is missing.

Update generated files.

Revert this because the interface hasn't been updated yet.

llvm-svn: 41703

Fix typo.

llvm-svn: 41702

llvm-svn: 41700

Update GEP constructors to use an iterator interface to fix
GLIBCXX_DEBUG issues.

llvm-svn: 41697

Emit proper "secrel" directive, where possible. This fixes invalid asm syntax of debug info on mingw32. Also, cleanup 
some stuff.

Implement some constant folding in SelectionDAG and
DAGCombiner using APFloat.  Remove double versions
of constructor and getValue from ConstantFPSDNode.

Use std::map instead of a (potentially very sparse) array to track val# defined by copy from the other live range. Minor compile time win when number of val# is large.

llvm-svn: 41640

llvm-svn: 41639

Use APFloat interfaces for more references, mostly
of ConstantFPSDNode.

Comments added. It now generates V5TE multiply instructions. However, it is still necessary to model PUWLSH bits more clearly.

Added support to fold X86 load / store instructions. This allow rematerialized loads to be folded into their uses.

llvm-svn: 41599

llvm-svn: 41598

Add a variant of foldMemoryOperand to fold any load / store, not just load / store from / to stack slots.
