It looks like we still don't recognize class-scope non-template

This builds ontop of the vect_worthwhile_without_simd_p refactoring
done earlier. It was wrong in dropping the appearant double checks
for operation support since the optab check can happen with an

might not actually support the op

Hi,
I forgot to add -fdump-ipa-inline to options of

of the dumps it was looking for had a double space, so I removed it
too.

All allocators are required to have operator== so that should not be a
problem

Some newly introduced tests in
23_containers/unordered_map/cons/default.cc revealed that we are forcing
the allocator type to have a operator==.
It can be avoided by checking allocator_traits::is_always_equal.

Hi,
Some scan-assembler tests for SVE code generation were erroneously
split over multiple lines - meaning they became invalid. This patch
gets the tests working again by putting each test on a single line.
The extract_[1234].c tests are corrected to expect that extracted
32-bit values are moved

Hi,
I've corrected the quoting and moved everything on to one line.
Ok for master?
Thanks,

tests to little-endian targets.
From: Richard Sandifo
When we build the COMPONENT_REF of a formerly volatile local off
the FRAME decl we have to make sure to mark the COMPONENT_REF
as TREE_THIS_VOLATILE. While the GIMPLE operand scanner looks
at the FIELD_DECL this is not how volatile GENERIC refs work.

This patch allows GCC to constant fold (i | (i<<16)) | ((i<<24) | (i<<8)),
where i is an unsigned char, or the equivalent (i*65537) | (i*16777472), to
i*16843009. The trick is to teach tree_nonzero_bits which bits may be
set in the result of a multiplication by a constant given which bits are

If get_gcov_type() returns a 64-bit type, then 64-bit atomic operations in
hardware are required for the "atomic" method. Add a new method to force
atomic operations even if a library implementation (libatomic) must be used.
