Subject: * Remove obselete code for unsized arrays
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=2761e9f076bbe6c961629aece62db4b836a41ef8;p=oota-llvm.git

* Remove obselete code for unsized arrays
* Add new function printTypeAtLeastOneLevel used to...
* Print the symbol table *WITH SYMBOLIC TYPES*.  Now we get:
       %tree = type { int, %tree*, %tree* }
  in the type definition section of the disassembled output instead of
       %tree = type { int, \2*, \2* }
  the different for the health benchmark and power are simply amazing.
