1ddf684f4c Major bug fix though it happened rarely (only on a compare after an 
integer overflow):
We need to use %icc and not %xcc for comparisons on 32-bit or smaller
integer values.

52e1c7001e Regression test for bug in reg. allocation that was using %xcc instead 
of %icc even for 32-bit and smaller comparisons.

20fcdbc808 Apparently, the "regType" and "regClass" used in the Sparc backend are not both 
correct: empirically, "regType" is wrong for a number of registers. Thus, one
can only rely on the "regClass" to figure out what kind of register one is
dealing with.

This change switches to using only "regClass" and adds a few extra DEBUG() print
statements and a few clean-ups in comments and code, mostly minor.

8dd0e2fb27 * Force all "don't care" bits to 0 so that there are absolutely no unset bits in 
the TableGen descriptions; all unset bits are thus errors.
* As a result, found and fixed instructions where some operands were not
  actually assigned into the right portion of the instruction.

009e42dd43 * If compiling on X86 or Sparc, automagically enable the JIT for that arch 
* Setting ENABLE_X86_JIT or ENABLE_SPARC_JIT on the `make' command-line will
  force the inclusion of that JIT on a different architecture
* If neither JIT is enabled (e.g., compiling on a different architecture), the
  -march option will not be available to LLI.
* As a side effect of the $ARCH variable, the Sparc LLI can now link just a bit
  faster by not including the x86 library.

ec0f8a8150 Removed the CPPFLAGS and CFLAGS variables since the -DHAVE_CONFIG_H messes 
up the test suite.  Since all the LLVM software assumes that config.h exists,
we can just do away with it for now.

84f4ef26b8 Force fixed-size but large alloca objects to the dynamically allocated 
area to avoid using up precious stack space within the 4095 offset limit
from %fp.  Such objects that would themselves live at a large offset
were being put there already so this is a simple change.

5ce2683cd2 (1) Major bug fix: DecomposeArrayRef() replaces its argument instr. and 
deletes it, but we were merrily trying to fix the operands of that
    instruction anyway!  Instead, fix the replacement instruction.

(2) An Improvement: Check for and extract global values in all operands,
    not just in known pointer operands.  For example, they can occur in
    call arguments, and probably other unforeseeable places as well.
    This also eliminates the special-case handling of Load and Store.

daa346c89a A def. operand of a machine instruction may be an ordinary Value*, 
not just an Instruction*, at least in one unfortunate case:
the first operand to the va_arg instruction.
Modify ValueToDefVecMap to map from Value*, not Instruction*.
