for pointing this out!

fcd60a010b The code emitter generator only supports targets with 32-bit instruction
words.  There is no way for one of these targets to have a > 32-bit immediate!

551ccae044 Changes For Bug 352
Move include/Config and include/Support into include/llvm/Config,
include/llvm/ADT and include/llvm/Support. From here on out, all LLVM
public header files must be under include/llvm/.

2b27b88716 This was a good idea, but until this does not break the build of
lib/Target/Sparc, we should not use it.

d7efef9d14 The CodeEmitterGenerator used to consider ANY uninitialized field as being an
operand (unless it's annul or predict).  Now we only consider fields to be
operands if they are uninitialized AND used in the "Inst" field.

f6e5217b54 Fixed a bug: outputting name of variable instead of its value.
Also, placed DEBUG() guards around debug information so that the generated file
is much smaller and hence should be faster to preprocess/compile.

7eac4766b1 This optimization greatly enhances efficiency of creating new instructions by
masking and shifting operands directly into their place in the instruction,
instead of the old-fashioned way of ORing in each bit separately.

48aa824279 Stop using the `Offset' variable, as we are cycling through the bits of a field
initializer and the loop index variable already carries the offset information
that we need.

cbfde0a612 * Now outputting a static function getBinaryCodeForInstr() (JIT-accessible)
* For debugging purposes:
  + output the predefined bit pattern of the instruction
* Fixed inefficiency: only load an operand from MachineInstr once
* Bug fix: did not advance bit index when seeing named bit-fields "annul", "cc"
  and "predict"
* Added a catch-all for non-supported instructions at the end of switch stmt.
