Chris Lattner 5166d35e5d Simplify code by removing InstLocalVarsVisitor, replacing it with a simple
inst_iterator.

Chris Lattner 30ad3a3238 * Clean up how PHI nodes are handled
* 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

Chris Lattner 48cd6330d7 Emit:
l3_reg109 = l81_this->field0;
Instead of:
  l3_reg109 = l81_this[0u].field0;

where possible

Chris Lattner 4933e7e02d * Print structures types correctly
* Clean up generated code to not emit basic block labels and goto
  instructions if they are unneccesary (for example, fall throughs)

Chris Lattner 132ba2a411 * Continue cleanup of type printing code
* 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

Chris Lattner eed155e6a0 Gut the type printing code so there is only one copy of it instead of 3

Chris Lattner c99a44eb25 * Remove dead "constant printing" code
* 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.

Chris Lattner 1532dbfead Remove gross "Operand" instance variable

Chris Lattner c897bddb17 Simplify and clean up function calls.
Now indirect function calls work, except that function pointer types are not correct.

Chris Lattner 2fca988a57 * Remove dead function
* Print C strings correctly
* Expand C escape sequences nicely (ie \n \t, etc get generated instead of hex escapes)

Chris Lattner af14c8d51f Make Getelementptr, load & store all work the right way.
Handle global variables correctly.

Chris Lattner 7fbd831ce5 Many random fixes:
* Use binary operator logic for shifts instead of cloning code
 * Unary not is '~' not '!'

Chris Lattner ec8243a8d4 Incorporate and purge function before and after printing them so unnamed values
have some hope of working right.

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

Chris Lattner 234ad49817 Factor out the code to print a value to ONE place.
It turns out that unnamed values DO NOT work at all, that's next on the list.
