Often the whole CFG does not need to be analyzed, for example,
when optimising a loop, only certain registers are of interest.
Perhaps there should be a bitmap argument to df_analyse to specify
which registers should be analyzed?
which registers should be analyzed?
NOTES:
Embedded addressing side-effects, such as POST_INC or PRE_INC, generate
both a use and a def. These are both marked read/write to show that they
both a use and a def. These are both marked read/write to show that they
are dependent. For example, (set (reg 40) (mem (post_inc (reg 42))))
will generate a use of reg 42 followed by a def of reg 42 (both marked
read/write). Similarly, (set (reg 40) (mem (pre_dec (reg 41))))
will generate a use of reg 42 followed by a def of reg 42 (both marked
read/write). Similarly, (set (reg 40) (mem (pre_dec (reg 41))))
generates a use of reg 41 then a def of reg 41 (both marked read/write),
even though reg 41 is decremented before it is used for the memory
address in this second example.
