Looking at PR77308, one of the issues is that the bswap optimization 
phase doesn't work on ARM.  This is due to an odd check that uses
SLOW_UNALIGNED_ACCESS (which is always true on ARM).  Since the testcase
in PR77308 generates much better code with this patch (~13% fewer
instructions), it seems best to remove this check.

So far all target implementations of the separate shrink-wrapping hooks
use the DF LIVE info to figure out around which basic blocks the non-
volatile registers need to be saved.  This is done by looking at the
IN+GEN+KILL sets of the basic blocks.  However, that doesn't work for
registers that DF says are defined in the entry block, or used in the
exit block.

This patch introduces a local flag DF_SCAN_EMPTY_ENTRY_EXIT that says
no registers should be defined in the entry block, and none used in the
exit block.  It also makes try_shrink_wrapping_separate use it.  The
rs6000 port is changed to use IN+GEN+KILL for the LR component.

The transformations made by make_compound_operation apply
only to scalar integer modes.  The fix for PR70944 had enforced
that by returning early for vector modes at the top of the
function.  However, the function is supposed to be recursive,
so we should continue to look at integer suboperands even if
the outer operation is a vector one.

This patch instead splits out the non-recursive parts
of make_compound_operation into a subroutine and checks
that the mode is a scalar integer before calling it.
The patch was originally written to help with the later
conversion to static type checking of mode classes, but it
also happened to reenable optimisation of things like
vec_duplicate operands.

Note that the gen_lowparts in the PLUS and MINUS cases
were redundant, since new_rtx already had mode "mode"
at those points.

When one uses ld.gold to build gcc, the thread sanitizer doesn't work,
because gold is more conservative when applying TLS relaxations than
ld.bfd. In this case a missing initial-exec attribute on a declaration
causes gcc to assume the general dynamic model. With ld.bfd this gets
relaxed to initial exec when linking the shared library, so the missing
attribute doesn't matter. But ld.gold doesn't perform this optimization
and this leads to crashes on tsan instrumented binaries.

See: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78294

The CONCAT handling in emit_group_load chooses between doing
an extraction from a single component or forcing the whole
thing to memory and extracting from there.  The condition for
the former (more efficient) option was:

	  if ((bytepos == 0 && bytelen == slen0)
	      || (bytepos != 0 && bytepos + bytelen <= slen))

On the one hand this seems dangerous, since the second line
allows bit ranges that start in the first component and leak
into the second.  On the other hand it seems strange to allow
references that start after the first byte of the second
component but not those that start after the first byte
of the first component.  This led to a pessimisation of
things like gcc.dg/builtins-54.c for hppa64-hp-hpux11.23.

This patch simply checks whether the reference is contained
within a single component.  It also makes sure that we do
an extraction on anything that doesn't span the whole
component (even if it's constant).

If the size passed in to rtx_addr_can_trap_p was zero, the frame
handling would get the size from the mode instead.  However, this
too can be zero if the mode is BLKmode, i.e. if we have a BLKmode
memory reference with no MEM_SIZE (which should be rare these days).
This meant that the conditions for a 4-byte access at offset X were
stricter than those for an access of unknown size at offset X.

This patch checks whether the size is still zero, as the
SYMBOL_REF handling does.

vect_transform_loop has to reduce three iteration counts by
the vectorisation factor: nb_iterations_upper_bound,
nb_iterations_likely_upper_bound and nb_iterations_estimate.
All three are latch execution counts rather than loop body
execution counts.  The calculations were taking that into
account for the first two, but not for nb_iterations_estimate.

this and to add a bit more commentary about what is going on.

Needed this to test the effect of the SVE patches on other targets.

gcc/
	* config/pdp11/pdp11.c: Include dbxout.h.

From-SVN: r242474

The old code still built thanks to the brackets in the definition
of XVECEXP.

gcc/
	* config/arc/arc.c (arc_loop_hazard): Add missing brackets.

From-SVN: r242473

The test assumes short is always smaller than int, and therefore does not 
expect a warning when the logical operands are of type short and int.

This isn't true for the avr - shorts and ints are of the same size, and
therefore the warning triggers for the above case also.

Fix by explicitly typedef'ing __INT32_TYPE for int and __INT16_TYPE__ for short
if the target's int size is less than 4 bytes.

	* c-c++-common/Wlogical-op-1.c: Use __INT{16,32}_TYPE__ instead
