Cool. Thanks a ton. Actually I am using an older version (rather old)
of the compiler currently. And hence when I read through the code, I did
not have the comments. After seeing your mail, I checked the gcc 3.0
sources and there it is pretty clearly mentioned that after
the call to last jump_optimize, we do not have the CFG information.
Just curious, why is it that the memory is free'd pretty late in the
process? Why is it not free'd immediately? Why the function
free_basic_block_vars is called after final?
