This patch enhances mixed condition pattern detection to work with

In over-widening pattern we expect the last statement to be a type

Hi,
As described in PR 51269, the vectorizer adjusts number of prologue loop
iterations according to cost model, but never uses the result. This happens
because the result is not returned from the function that computes it, and

Well, it seems to be different what everybody else does and it's
highly redundant for a whole bunch of lines.
But, it solves my diff issue and the overly long lines as well.
Your patch changes both dump-file

Hi!
The following testcase ICEs, because gsi_end_p (*gsi) and thus
there is no stmt after it from which to copy over the location.
As can be seen in the PR, we could do ugly hacks to retrieve locus
from previous stmt
Hi,
This patch changes the default vector size for auto-vectorization on
ARM NEON to 128 bits. This new version is a result of a discussion
with Richard and Ramana.
wwwdocs changes will follow shortly.
Bootstrapped and tested on arm-linux-gnueabi. The testsuite changes
were also checked on
Hi,
The first part was already reviewed several months ago, but I am
resubmitting it along with -mvectorize-with-neon-double documentation.
OK to commit?
Thanks,
Ira

Hi,
This patch adds a check in vect_operation_fits_smaller_type () that a
widening statement has a stmt_vec_info, i.e., that it is a loop
statement.
Bootstrapped and tested on powerpc64-suse-linux.
Committed.

Hi,
In vectorization of reduction we use a dummy def_type when getting a
copy of a vector operand. Therefore, instead of just using a constant
operand from a previous copy, we try to create a copy of it, causing
the failure. This patch adds a call to vect_is_simple_use () to get a
correct

Hi,
This patch adds another missing check for SLP reduction detection: we
should check that a statement in a reduction chain has either one use
inside the loop, or two uses: in the reduction phi node and the loop exit
phi node.
Bootstrapped and tested on powerpc64-suse-linux.
Applied to trunk.
When last week a testcase using mmap was posted with a copy of some old
(and wrong) list of targets supporting mmap, I noticed what mess we have
here. To fix this, I've introduced a new effective-target keyword mmap
and use it in all testcases.
Two minor changes to the tests were required:

prevent unrolling via command line switch?

Hi,
The vectorizer performs the following alias checks for data-refs with
unknown dependence:
((store_ptr_0 + store_segment_length_0) = load_ptr_0)
|| (load_ptr_0 + load_segment_length_0) = store_ptr_0))
where segment_length is data-ref's step in the loop multiplied by the
loop's number of
Hi,
This patch tries to reduce over-promotion of vector operations that
could be done with narrower elements, e.g., for
char a;
int b, c;
short d;
b = (int) a;
c = b 2;
d = (short) c;
we currently produce six vec_unpack_lo/hi_expr statements for
char-int conversion and then two
