uz 82b998117a Added a separate output module that is used to manage the output file.

output file was generated. Now the output is sent to either <inputstem>.i or
the file named in the -o option.

 2004-06-15 20:05:54 +00:00
cuz 3ac1a08baf Cleaned up the code used for handling jump labels and the label name. 
Fixed a problem that caused the optimizer not to detect that flags set by
a load are used, if the use is "hidden" behind an unconditional branch. This
caused the optimizer to remove the load.

 2004-06-07 21:16:49 +00:00
cuz aa39d98cbc When changing the reference to a jump label, do also replace the string 
argument for the instruction with the name of the new jump label. This
allows CodeEntriesAreEqual to work in all cases, and therefore optimizations
based on this function will also work more effectively (or at all).
