2840a1b4ee For 16 and 32-bit multiplies, use the IMUL instruction instead of the MUL instruction. 
This allows us to not force the use of the EAX/AX registers!

0619cdf430 Added a hack that takes the path relative to the home directory into account 
if a home directory is provided by the environment.

a53d83603e The modifications to LD_LIBRARY_PATH now add the specified paths to the 
beginning of LD_LIBRARY_PATH as opposed to simply replacing it.
This allows users to use LD_LIBRARY_PATH when running tests (useful for
when they have installed their own version of GCC).

365e583866 * Changes to make NodeType be private to DSNode. 
* Add new MultiObject flag to DSNode which keeps track of whether or not
  multiple objects have been merged into the node, allowing must-alias info
  to be tracked.

a734842f8a Rename many instructions to their Intel asm-compatible names. This 
involves removing the [bwl] suffixes from instruction names, as well
as some other distinguishing marks (32/64/80 on fp insns, _i suffixes, etc.)

Lowercase all instr. names as well for consistency's sake.

beb320af87 Add Initialization and Finalization methods for the Printer pass, 
to print various things on a module-by-module basis (currently, only the
former is used).

Don't print < > around names. The assembler can't take it.

Print pseudoinstructions only as comments. The poor little assembler can't
take that, either.

19420e8daf lib/Target/Sparc/Sparc.cpp: 
Move LowerAllocations, PrintFunction, and SymbolStripping passes, and
  the corresponding -disable-strip and -d options, over here to the SPARC
  target-specific bits of llc. Rename -d to -dump-asm.

tools/llc/Makefile:
 Reindent. Add x86 library so that llc compiles again.

tools/llc/llc.cpp:
 Remove support for running arbitrary optimization passes. Use opt instead.
 Remove LowerAllocations, PrintFunction, and SymbolStripping passes, as noted
  above.
 Allow user to select a backend (x86 or SPARC); default to guessing from
  the endianness/pointer size of the input bytecode file.
 Fix typos.
 Delete empty .s file and exit with error status if target does not support
  static compilation.

floating-point constants or as references to stack-allocated variables.
