[AArch64] Used prefer aliases SXTL(2) and UXTL(2)
The SSHL and USHL instructions are used with a shift operand of zero to
sign and zero-extend integer vectors into wider modes.
GCC makes extensive use of them to "unpack" vectors.
AArch64 defines a shorthand alias for that case. Instead of writing:
SSHLL <Vd>.<Ta>, <Vn>.<Tb>, 0
we can write
SXTL <Vd>.<Ta>, <Vn>.<Tb>
Similar for the unsigned versions and the high-part versions (SSHL2 -> SXTL2).
This makes the assembly of vectorised functions a bit more readable.

Fix phi backedge detection in backprop (PR85989)
This PR is a nasty wrong code bug due to my fluffing a test for a
backedge in gimple-ssa-backprop.c. Backedges are supposed to be
from definitions in the statement we're visiting to uses in statements
that we haven't visited yet. However, the check failed to account for
PHIs in the current block that had already been processed, so if two
PHIs in the same block referenced each other, we'd treat both
references as backedges.
In more detail:
The first phase of the pass goes through all statements in an arbitrary
order, making optimistic assumptions about any statements that haven't
been visited yet. The second phase then calculates a correct
(supposedly maximal) fixed point.
Although the first phase order is arbitrary in principle, we still use
the CFG rpo to cut down on the backedges. This means that the only
thing that's truly arbitrary is the order that we process the PHIs
in a block. Any order should be OK and should eventually give the
same results. But we have to follow whatever order we pick,
and the pass wasn't doing that.

Inline strcmp with small constant strings
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83026
missing strlen optimization for strcmp of unequal strings
The design doc for PR78809 is at:
https://www.mail-archive.com/gcc@gcc.gnu.org/msg83822.html
this patch is for the second part of change of PR78809 and PR83026:
B. for strncmp (s1, s2, n) (!)= 0 or strcmp (s1, s2) (!)= 0
B.1. (PR83026) When the lengths of both arguments are constant and
it's a strcmp:
* if the lengths are NOT equal, we can safely fold the call
to a non-zero value.
* otherwise, do nothing now.
B.2. (PR78809) When the length of one argument is constant, try to replace
the call with a __builtin_str(n)cmp_eq call where possible, i.e:
strncmp (s, STR, C) (!)= 0 in which, s is a pointer to a string, STR is a
string with constant length, C is a constant.
if (C <= strlen(STR) && sizeof_array(s) > C)
{
replace this call with
__builtin_strncmp_eq (s, STR, C) (!)= 0
}
if (C > strlen(STR)
{
it can be safely treated as a call to strcmp (s, STR) (!)= 0
can handled by the following strcmp.
}
strcmp (s, STR) (!)= 0 in which, s is a pointer to a string, STR is a
string with constant length.
if (sizeof_array(s) > strlen(STR))
{
replace this call with
__builtin_strcmp_eq (s, STR, strlen(STR)+1) (!)= 0
}
later when expanding the new __builtin_str(n)cmp_eq calls, first expand them
as __builtin_memcmp_eq, if the expansion does not succeed, change them back
to call to __builtin_str(n)cmp.

x86: Re-enable partial_reg_dependency and movx for Haswell
r254152 disabled partial_reg_dependency and movx for Haswell and newer
Intel processors. r258972 restored them for skylake-avx512. For Haswell,
movx improves performance. But partial_reg_stall may be better than
partial_reg_dependency in theory. We will investigate performance impact
of partial_reg_stall vs partial_reg_dependency on Haswell for GCC 9. In

Haswell in GCC 8.

Because the wide character types are neither signed integer types nor

of the correct size and the lowest rank (which is not necessarily the
underlying type). Reuse the helpers for enumeration types to select the
correct integer.
The refactoring of __make_unsigned_selector and __make_signed_selector

[AArch64] Improve LDP/STP generation that requires a base register
This patch generalizes the formation of LDP/STP that require a base register.
In AArch64, LDP/STP instructions have different sized immediate offsets than
normal LDR/STR instructions. This part of the backend attempts to spot groups
of four LDR/STR instructions that can be turned into LDP/STP instructions by
using a base register.
Previously, we would only accept address pairs that were ordered in ascending
or descending order, and only strictly sequential loads/stores. In fact, the
instructions that we generate from this should be able to consider any order
of loads or stores (provided that they can be re-ordered). They should also be
able to accept non-sequential loads and stores provided that the two pairs of
addresses are amenable to pairing. The current code is also overly restrictive
on the range of addresses that are accepted, as LDP/STP instructions may take
negative offsets as well as positive ones.
This patch improves that by allowing us to accept all orders of loads/stores
that are valid, and extending the range that the LDP/STP addresses can reach.

* libgnat/a-direct.adb, libgnat/a-direct.ads (Name_Case_Equivalence):
Add implementation.
(Start_Search): Modify to use Start_Search_Internal
(Start_Search_Internal): Add to break out an extra flag for searching
case insensative due to the potential for directories within the same
OS to allow different casing schemes.
* sysdep.c (__gnat_name_case_equivalence): Add as a default fallback
for when the more precise solution fails.
