which global variables would have name collisions if they were not mangled,
and use this info to mangle them iff they would collide.

works much better than it used to.

1. Avoid printing *(&globalvariable), instead print globalvariable alone
   as a special case.
2. Inline subexpressions into expressions as much as legal that preserves
   execution characteristics of expressions.  Now we get nice (but
   over-parenthesized, oh well) things like:

     ltmp_428_7 = spec__putc(((unsigned char )((bsBuff) >> 24)), (bsStream));

   instead of five seperate instructions (bsBuff & bsStream are globals).

* Reorder code in the file to make it more logically laid out.

llvm-svn: 2586

then printing it out, just print as we go.

inst_iterator.

llvm-svn: 2584

* Correct global variable references
* Fix loads & stores with zero indices
* Do not emit an else part of a branch if there is no code (no phi node
  and a fallthrough branch), makes code more readable to get:
  if (l2_cond240) {
    goto l13_bb10;
  }

with no else{} branch

  l3_reg109 = l81_this->field0;
Instead of:
  l3_reg109 = l81_this[0u].field0;

where possible

llvm-svn: 2579

* Clean up generated code to not emit basic block labels and goto
  instructions if they are unneccesary (for example, fall throughs)

llvm-svn: 2578

* Print a newline after a malloc instruction
* Convert unprintable characters to x_ instead of _x so that we don't
  generate identifiers that start with underscores

llvm-svn: 2577

llvm-svn: 2576

* Mangle names with only a prefix so that they are easier on the eyes.
* Put spaces around binary operators with low precedence to make them easier to read
* Don't prefix function names with &, although it's correct, it's unnecesary and
  easier to read without it.

llvm-svn: 2575

Remove lots of unneccesary arguments to methods

llvm-svn: 2574

Now indirect function calls work, except that function pointer types are not correct.

llvm-svn: 2573

* Print C strings correctly
* Expand C escape sequences nicely (ie \n \t, etc get generated instead of hex escapes)

llvm-svn: 2572

Handle global variables correctly.

llvm-svn: 2571

 * Use binary operator logic for shifts instead of cloning code
 * Unary not is '~' not '!'

llvm-svn: 2570

have some hope of working right.

Function calls do not try to emit an lvalue if they return void.

llvm-svn: 2569

It turns out that unnamed values DO NOT work at all, that's next on the list.
