As a side-effect, the patch fixes the REV handling for diff==1,

always actually drop it. This patch fixes it.
But that on its own is too pessimistic, it turns out, and we generate

Don't treat zero-sized ranges as overlapping
Most GCC ranges seem to be represented as an offset and a size (rather
than a start and inclusive end or start and exclusive end). The usual
test for whether X is in a range is of course:
x >= start && x < start + size
or:
x >= start && x - start < size
which means that an empty range of size 0 contains nothing. But other
range tests aren't as obvious.
The usual test for whether one range is contained within another
range is:
start1 >= start2 && start1 + size1 <= start2 + size2
while the test for whether two ranges overlap (from ranges_overlap_p) is:
(start1 >= start2 && start1 < start2 + size2)
|| (start2 >= start1 && start2 < start1 + size1)
i.e. the ranges overlap if one range contains the start of the other
range. This leads to strange results like:
(start X, size 0) is a subrange of (start X, size 0) but
(start X, size 0) does not overlap (start X, size 0)
Similarly:
(start 4, size 0) is a subrange of (start 2, size 2) but
(start 4, size 0) does not overlap (start 2, size 2)
It seems like "X is a subrange of Y" should imply "X overlaps Y".
This becomes harder to ignore with the runtime sizes and offsets
added for SVE. The most obvious fix seemed to be to say that
an empty range does not overlap anything, and is therefore not
a subrange of anything.
Using the new definition of subranges didn't seem to cause any
codegen differences in the testsuite. But there was one change
with the new definition of overlapping ranges. strncpy-chk.c has:
memset (dst, 0, sizeof (dst));
if (strncpy (dst, src, 0) != dst || strcmp (dst, ""))
abort();
The strncpy is detected as a zero-size write, and so with the new
definition of overlapping ranges, we treat the strncpy as having
no effect on the strcmp (which is true). The reaching definition
is the memset instead.
This patch makes ranges_overlap_p return false for zero-sized
ranges, even if the other range has an unknown size.

Widening optab cleanup
widening_optab_handler had the comment:
/* ??? Why does find_widening_optab_handler_and_mode attempt to
widen things that can't be widened? E.g. add_optab... */
if (op > LAST_CONV_OPTAB)
return CODE_FOR_nothing;
I think it comes from expand_binop using
find_widening_optab_handler_and_mode for two things: to test whether
a "normal" optab like add_optab is supported for a standard binary
operation and to test whether a "convert" optab is supported for a
widening operation like umul_widen_optab. In the former case from_mode
and to_mode must be the same, in the latter from_mode must be narrower
than to_mode.
For the former case, find_widening_optab_handler_and_mode is only really
testing the modes that are passed in. permit_non_widening must be true
here.
For the latter case, find_widening_optab_handler_and_mode should only
really consider new from_modes that are wider than the original
from_mode and narrower than the original to_mode. Logically
permit_non_widening should be false, since widening optabs aren't
supposed to take operands that are the same width as the destination.
We get away with permit_non_widening being true because no target
would/should define a widening .md pattern with matching modes.
But really, it seems better for expand_binop to handle these two
cases itself rather than pushing them down. With that change,
find_widening_optab_handler_and_mode is only ever called with
permit_non_widening set to false and is only ever called with
a "proper" convert optab. We then no longer need widening_optab_handler,
we can just use convert_optab_handler directly.
The patch also passes the instruction code down to expand_binop_directly.
This should be more efficient and removes an extra call to
find_widening_optab_handler_and_mode.

Add gen_(const_)vec_duplicate helpers
This patch adds helper functions for generating constant and

it is then easier to use:
(const:M (vec_duplicate:M X))
for a broadcast of X, even if the number of elements in M isn't known

constant and non-constant duplicates in the same way.
In the target code, the patch uses gen_vec_duplicate instead of
gen_rtx_VEC_DUPLICATE if handling constants correctly is potentially
useful. It might be that some or all of the call sites only handle
non-constants in practice, in which case the change is a harmless

Prevent invalid register mode changes in combine
This patch stops combine from changing the mode of an existing register
in-place if doing so would change the size of the underlying register
allocation size, as given by REGMODE_NATURAL_SIZE. Without this,
many tests fail in adjust_reg_mode after SVE is added. One example
is gcc.c-torture/compile/
20090401-1.c.

diagnostics: get rid of *_at_rich_loc in favor of overloading
Adding a fix-it hint currently involves changing e.g.:
error_at (token->location,
"unknown type name %qE; did you mean %qs?",
token->value, hint);
to:
gcc_rich_location richloc (token->location);
richloc.add_fixit_replace (hint);
error_at_rich_loc (&richloc,
"unknown type name %qE; did you mean %qs?",
token->value, hint);
to make the change from taking a location_t to a rich_location *.
This patch renames the "*_at_rich_loc" diagnostic entrypoints to use
the same function names for rich_location * as for location_t,
via overloading, to simplify the above change to just changing from:
error_at (token->location,
"unknown type name %qE; did you mean %qs?",
token->value, hint);
to:
gcc_rich_location richloc (token->location);
richloc.add_fixit_replace (hint);
error_at (&richloc,
"unknown type name %qE; did you mean %qs?",
token->value, hint);
thus saving space (and typing) and usually avoiding the need to reindent
the "error_at" invocation.
With this change, 0 is no longer acceptable as a location_t to these
entrypoints, as e.g.:
../../src/gcc/auto-profile.c:855:37: error: call of overloaded
'inform(int, const char [18])' is ambiguous
inform (0, "Not expected TAG.");
^
In file included from ../../src/gcc/auto-profile.c:35:0:
../../src/gcc/diagnostic-core.h:88:13: note: candidate:
'void inform(location_t, const char*, ...)'
extern void inform (location_t, const char *, ...) ATTRIBUTE_GCC_DIAG(2,3);
^~~~~~
../../src/gcc/diagnostic-core.h:89:13: note: candidate:
'void inform(rich_location*, const char*, ...)'
extern void inform (rich_location *, const char *, ...) ATTRIBUTE_GCC_DIAG(2,3);
^~~~~~
Such locations now need to be spelled out as UNKNOWN_LOCATION,
rather than 0.
I considered making the API take a rich_location & rather than a
rich_location *, but doing so would mean replacing
diagnostic_set_info
and
diagnostic_set_info_translated
with a constructor for diagnostic_info, which was a more invasive
change. Maybe in the future.

Subject: [PATCH] rs6000: Fix crash with big stack clash interval (PR82674)
If the user asks for a stack clash probe interval of 64kB, we currently
generate a "stdu rX,-65536(r1)" instruction. That instruction does not
exist (the offset is a 16-bit signed number). If the offset is too big
we should force it into a register and generate a "stdux rX,rY,r1"

Remove DImode expansions for 1-bit shifts
A left shift of 1 can always be done using an add, so slightly adjust rtx
cost for DImode left shift by 1 so that adddi3 is preferred in all cases,
and the arm_ashldi3_1bit is redundant.
DImode right shifts of 1 are rarely used (6 in total in the GCC binary),
so there is little benefit of the arm_ashrdi3_1bit and arm_lshrdi3_1bit
patterns. The generated code is better and faster without these shifts
as it allows early expansion, optimization and better register allocation.
