Step 2: Make plug compatible shell script to replace gccas binary.

llvm-svn: 33787
 2007-02-02 15:50:58 +00:00
Reid Spencer 22dbfb626f For PR1152: 
Step 1: Copy gccas functionality to opt. This endows opt with a new
-std-compile-opts option to get the set of optimization passes that
gccas used. It also adds -disable-inlining and -disable-opt which
both apply only if -std-compile-opts is given. The -strip-debug option
was also removed. It just makes sure that "-strip" gets done early and
is mostly there for compatibility with gccas. Finally, a new
-verify-each option will cause the verify pass to be run after each pass.

2. Fix indentation
3. Renumber the instruction opcodes after the Shift became a binary operator.

llvm-svn: 33777
 2007-02-02 02:30:19 +00:00
Reid Spencer 2341c22ec7 Changes to support making the shift instructions be true BinaryOperators. 
This feature is needed in order to support shifts of more than 255 bits
on large integer types.  This changes the syntax for llvm assembly to
make shl, ashr and lshr instructions look like a binary operator:
   shl i32 %X, 1
instead of
   shl i32 %X, i8 1
Additionally, this should help a few passes perform additional optimizations.
