Hi Richard
I just found that modifying match.pd may be a better way since for
forwprop-19.c, VEC_PERM_EXPR exists in all gimple until 235t.optimize with
current trunk code, that leave us no pass to ‘scan-tree-dump-not’.

That's not a problem per se, consistency is just immensely helpful if we

Hi,
There is a functionality as const_anchor in cse.cc. This const_anchor
supports to generate new constants through adding small gap/offsets to
existing constant. For example:
void __attribute__ ((noinline)) foo (long long *a)
{
*a++ = 0x2351847027482577LL;
*a++ = 0x2351847027482578LL;
}
T
The old stack stack was performed before the stack was dropped,
which would cause the detection tool to report a memory leak.
The current stack check scheme is as follows:
'-fstack-clash-protection':
1. When the frame->total_size is smaller than the guard page size,
the stack is dropped accord

Yes in principle zero extract should always be positive a
The following makes sure to reduce a multi-vector SLP reduction
accumulator to a single vector using vector operations if
easily possible (if the number of lanes in the vector type is
a multiple of the number of scalar accumulators).
Bootstrapped on x86_64-unknown-linux-gnu, testing in progress.

Epilogue vectorization is not set up to re-use a vectorized
accumulator consisting of more than one vector. For non-SLP
we always reduce to a single but for SLP that isn't happening.
In such case we currenlty miscompile the epilog so avoid this.

[Jakub, this is a cleaned up version of what we iterated on earlier
this summer. It contains additional smarts to propagate NAN signs on
entry. I'd like a nod before committing.]
This is the range-op entry for floating point PLUS_EXPR. It's the
most intricate range entry we have so far, because
op1_op2_relation can be called for relops (bool = a < b) as well as
regular binary operators (z = a + b). This patch adds the overloaded
method for floating point results.

The expression in (with { ... } is used like a statement expression
which means control flow that leaves it is not allowed. The following
explicitely diagnoses 'return' and fixes up the few cases that crept
into match.pd (oops). Any such return will prematurely end matching
the current expression

Just to note I was confused and DECL_FIELD_OFFSET can indeed be
different (but then are guaranteed to be constant), so the patch
looks correct.
