needs to know about every target's list of intrinsics.  Future work
will include converting the PowerPC target to this interface as an
example implementation.

but when legalizing the operation, we split the vector type and generate a library
call whose type needs to be promoted. For example, X86 with SSE on but MMX off, 
a divide v2i64 will be scalarized to 2 calls to a library using i64.

support GraphViz, I've been using the foo->dump() facility.  This
patch is a minor rewrite to the SelectionDAG dump() stuff to make it a
little more helpful.  The existing foo->dump() functionality does not
change; this patch adds foo->dumpr().  All of this is only useful when
running LLVM under a debugger.

Don't bother hoisting out a "cheap" instruction if all of its uses are PHIs. LICM "cheap" instructions are not particularly beneficial to start with. This will just end up making the copies harder to coalesce.

llvm-svn: 63728

For now, only hoist re-materilizable instructions. LICM will increase register pressure. We want to avoid spilling more instructions if it's possible.

there.

This changes the interpreter to use libffi. After this patch, the interpreter
will barely be able to call any external functions if built on a system without
libffi installed (just enough to pass 'make check' really). But with libffi,
we can now call any function that isn't variadic or taking a struct or vector
parameter (but pointer to struct is fine). Patch by Alexei Svitkine!
