Was not checking the first register in the register list.

Get the source register that isn't tied to the destination register correct,
even when the assembly source operand order is backwards.

that depends on MBlazeCodeGen. This is a layering violation that should really
be fixed.

For correctness, disable this for now.

Use the getIdentifier() method of the token, not getString(), otherwise
we keep the quotes as part of the symbol name, which we don't want.

consistency with other targets.

Note: These patterns only works in some cases because
many times the load sd node is bitcasted from a load
node of a different type.

determine if the value is negative and flip the sign accordingly.

options to llvm-build, so the all-targets etc. components are defined properly.

llvm-svn: 144255

handle defining the "magic" target related components (like native,
nativecodegen, and engine).
 - We still require these components to be in the project (currently in
   lib/Target) so that we have a place to document them and hopefully make it
   more obvious that they are "magic".

llvm-svn: 144253

change the generated library .a file name once we fully switch over, but
simplifies how we treat these targets without requiring more special casing
(since their library group name and the codegen library name currently map to
the same "llvm-config" style component name).

llvm-svn: 144251

 - Gives us a place to hang target specific metadata (like whether the target has a JIT).

llvm-svn: 144123

No functional change intended.

llvm-svn: 144122

Add support for trimming constants to GetDemandedBits. This fixes some funky
constant generation that occurs when stores are expanded for targets that don't
support unaligned stores natively.

llvm-svn: 144102

When this field is true it means that the load is from constant (runt-time or compile-time) and so can be hoisted from loops or moved around other memory accesses

llvm-svn: 144100

implements unaligned loads and stores with assembler macro-instructions
ulw, usw, ulh, ulhu, ush, and this patch emits corresponding instructions
instead of these macros. Since each unaligned load/store is expanded
into two corresponding loads/stores where offset for second load/store is
modified by +3 (for words) or +1 (for halfwords).

callee's responsibility to sign or zero-extend the return value.  The additional
test case just checks to make sure the calls are selected (i.e., -fast-isel-abort
doesn't assert).
