Every such optimization should add its requirements for profiled values to

|
insn_values_to_profile function. This function is called from branch_prob

There are currently two versions, RTL-based and tree-based. Over time
|
|
|
|
|
the RTL-based version may go away.
|
|
|
|
|
|
|
|
|
|
In the RTL-based version, the measured data is appended as REG_VALUE_PROFILE
|
|
|
|
|
note to the instrumented insn. The argument to the note consists of an
|
|
|
|
|
EXPR_LIST where its members have the following meaning (from the first to
|
|
|
|
|
the last):
|
2003-07-30 21:23:34 +02:00
|
|

|
|
|

|
|
-- type of information gathered (HIST_TYPE*)
|
|
|
|
|
-- the expression that is profiled
|
2005-03-29 13:45:51 +02:00
|
|
|
|
-- list of counters starting from the first one.
|
|
|
|
|
|
|
|
|
|
In the tree-based version, the measured data is pointed to from the histograms
|
|
|
|
|
field of the statement annotation of the instrumented insns. It is
|
|
|
|
|
kept as a linked list of struct histogram_value_t's, which contain the
|
|
|
|
|
same information as above. */

else

Note that when b = 0, no error will occur and x = a; this is correct,
|

as result of such operation is undefined.

Read or write of mem[address], where the value of address changes usually
|
|
|
|
|
by a constant C != 0 between the following accesses to the computation; with
|
|
|
|
|
-fspeculative-prefetching we then add a prefetch of address + C before
|
|
|
|
|
the insn. This handles prefetching of several interesting cases in addition
|
|
|
|
|
to a simple prefetching for addresses that are induction variables, e. g.
|
|
|
|
|
linked lists allocated sequentially (even in case they are processed
|
|
|
|
|
recursively).

TODO -- we should also check whether there is not (usually) a small
|
|
|

difference with the adjacent memory references, so that we do
|
|
|
|
|
not issue overlapping prefetches. Also we should employ some
|
|
|
|
|
heuristics to eliminate cases where prefetching evidently spoils
|
|
|
|
|
the code.

There are other useful cases that could be handled by a similar mechanism,

|
|
|
|
for example:
|
|
|
|
|
|
|
|
|
|
for (i = 0; i < n; i++)
|
|
|
|
|
...
|
|
|
|
|
|
|
|
|
|
transform to (for constant N):
|
|
|
|
|
|
|
|
|
|
if (n == N)
|
|
|
|
|
for (i = 0; i < N; i++)
|
|
|
|
|
...
|
|
|
|
|
else
|
|
|
|
|
for (i = 0; i < n; i++)
|
|
|
|
|
...
|
|
|
|
|
making unroller happy. Since this may grow the code significantly,
|
|
|
|
|
we would have to be very careful here. */
