Hi,
This is a rewrite of the tag collision avoidance patch that Kugan had
written as a machine reorg pass back in February.
The falkor hardware prefetching system uses a combination of the
source, destination and offset to decide which prefetcher unit to
train with the load. This is great when

This patch makes strlen range computations more conservative.
Firstly if there is a visible type cast from type A to B before passing
then value to strlen, don't expect the type layout of B to restrict the
possible return value range of strlen.
Furthermore use the outermost enclosing array
Hi.
This is implementation of new built-in that can be used for more fine
tweaking of probability. Micro benchmark is attached as part of the PR.
Patch can bootstrap on ppc64le-redhat-linux and survives regression tests.

This minor clean-up avoids repeating the test for double reductions

The aim of this series is to:

* tree-vectorizer.h (stmt_vec_info): Move typedef earlier in file.
This patch adds a vec_info replacement for vinfo_for_stmt. The main
difference is that the new routine can cope with arbitrary statements,
so there's no need to call vect_stmt_in_region_p first.
The patch only converts calls that are still needed at the end of the
series. Later patches get rid
vectorizable_reduction has old code to cope with cases in which the
given statement belongs to a reduction group but isn't the first statement.
That can no longer happen, since all statements in the group go into the
same SLP node, and we only check the first statement in each node.
The point is
vect_free_slp_tree had:
gimple *stmt;
FOR_EACH_VEC_ELT (SLP_TREE_SCALAR_STMTS (node), i, stmt)
/* After transform some stmts are removed and thus their vinfo is gone. */
if (vinfo_for_stmt (stmt))
{
gcc_assert (STMT_VINFO_NUM_SLP_USES (vinfo_for_stmt (stmt)) > 0);
vect_is_slp_reduction and vect_is_simple_reduction had two instances
each of:
&& (is_gimple_assign (def_stmt)
|| is_gimple_call (def_stmt)
|| STMT_VINFO_DEF_TYPE (vinfo_for_stmt (def_stmt))
== vect_induction_def
The usual vectoriser dance to create new assignments is:
new_stmt = gimple_build_assign (vec_dest, ...);
new_temp = make_ssa_name (vec_dest, new_stmt);

This is missing the synchronized_pool_resource and
unsynchronized_pool_resource classes but is otherwise complete.
This is a new implementation, not based on the existing code in
, but memory_resource and
polymorphic_allocator ended up looking almost the same anyway.

As the title mentions, this patch generalizes the state propagation and
synchronization code. Note that while the patch makes reference to
large_vectors, they are not enabled in nvptx_goacc_validate_dims.
Therefore, only the worker case is exercised in this patch.

Chung-Lin had originally defined TARGET_SET_CURRENT_FUNCTION as part
of his gang-local variable patch. But I intend to introduce those
changes at a later time. Eventually the state propagation code will
utilize nvptx_set_current_function to reset the reduction buffer
