For pointer reductions we need to convert the initial value to
the vector component integer type.
Re-bootstrap and regtest running on x86_64-unknown-linux-gnu.
I've ran into this latent bug on the force-slp branch.
Richard.
* tree-vect-loop.cc (get_initial_defs_for_reduction): Convert
When we have a non-grouped access we bogously multiply by zero.
This shows most with single-lane SLP but also happens with
the multi-lane splat case.

Hi!
The optimize_range_tests_to_bit_test optimization normally emits a range
test first:
if (entry_test_needed)
{
tem = build_range_check (loc, optype, unshare_expr (exp),
false, lowi, high);
if (tem ==
On s390 the following tests fail

Vector testcase (C++ only) for the missing add case:
```
#define vector4 __attribute__((vector_size(4*sizeof(int
void unopt(vector4 int *v) {
vector4 int t = *v;
vector4 int t1 = t + 8;

Previously effective target fortran_real_c_float128 never

testcase:
```
namespace __cxxabiv1

extern "C" int __cxa_thread_atexit(void (__thiscall* dtor)(void*), void* obj,

The combiner attempts to optimize a zero-extension of a logical right shift
using zero_extract. We already utilize this optimization for those cases
that result in a single instructions. Let's add a insn_and_split
pattern that also matches the generic case, where we can emit an
optimized sequence
The lshr3_zero_extend_4 pattern targets bit extraction
with zero-extension. This pattern represents the canonical form
of zero-extensions of a logical right shift.
The same optimization can be applied to sign-extensions.
Given the two optimizations are so similar, this patch converts
the existing
The pattern lshrsi3_zero_extend_2 extracts the MSB bits of the lower
32-bit word and zero-extends it back to DImode.
This is realized using srliw, which operates on 32-bit registers.
The same optimziation can be applied to sign-extensions when emitting
a sraiw instead of the srliw.
Given these
We already optimize a sign-extension of a right-shift by 31 in
si3_extend. Let's add a test for that (similar to
zero-extend-1.c).

* gcc.target/riscv/sign-extend-1.c: New test.

Looks like the testcase should also be skipped for mingw/cygwin too.

So I was going for the elf semantics here but Mach-O semantics says the
function is NOT replacable unless it was weak.
Anyways this is just a dg-skip-if for darwin and I will add it with a note
saying

Hi,
Since r9-4728 the powerpcspe support had been removed, this
follow-up patch is to remove the remaining pieces in testsuite.
Regtested on powerpc64-linux-gnu P8/P9 and
powerpc64le-linux-gnu P9 and P10.
I'm going to push this soon if no objections.
BR,

gcc/testsuite/ChangeLog:
Hi,
This patch enables overlapped by-piece operations. On rs6000, default
move/set/clear ratio is 2. So the overlap is only enabled with compare
by-pieces.
Bootstrapped and tested on powerpc64-linux BE and LE with no
regressions. Is it OK for the trunk?
Thanks
