 Is there any info on optimizers that take advantage of profiler
information? That is, the compiler creates some code that generates
profiler information, then the code is run, then the compiler is
run again, and it used the generated profiler information to
generate better code.
 Is there any info on optimizers that take advantage of runtime
assertions? This can help with anti dependencies, but it may have
other advantages; for instance, if an integer is guaranteed to be
within a certain range, then some operations on it may be cheaper,
 If statement A has a def-use chain to statement B, does it follow
that statement B has a use-def chain to statement A? Is this an
"if and only if" relation? I've checked the Dragon book, but it
seems to have no opinion on this.
Thanks for any help,
[Multiflow had a profiler-based optimizer and I'm sure that others do, too.
