44460da591 Probe for flags before using them to try to help compiling with 
compilers that don't support those flags.  This hopefully will help
gcc 3.X compile this code.  http://llvm.org/PR3487

7a2e7e5c20 Revert the previous commit. It seems it didn't 
really solve the problem.  Also it changed the
name from libLLVMgold to LLVMgold (correcting
the name resulted in the original problem
suddenly reappearing).

between call frame setup/restore points.  Unfortunately, this regresses 
code size a bit, but at least it's correct now!

buffer after it creates the Module. Thus, we don't need to store this pointer
in claimed_file.

d24479730a New feature: add support for target intrinsics being defined in the 
target directories themselves.  This also means that VMCore no longer
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.

e5ab34e05d Avoids generating a legalization assert for the case where a vector type is legal 
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.

80d6977e90 Since I'm obliged to work with a development OS that currently doesn't 
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.

45e94d68d7 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.

f9c5c5c7a2 Reapply patch from r62553, with a fix to avoid looking for an ffi.h that isn't 
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!
