    • i386: Fix ICEs on TImode signed overflow add/sub patterns [PR93376] · c124b345 
      The following testcase ICEs, because during try_combine of i3:
(insn 18 17 19 2 (parallel [
            (set (reg:CCO 17 flags)
                (eq:CCO (plus:OI (sign_extend:OI (reg:TI 96))
                        (const_int 1 [0x1]))
                    (sign_extend:OI (plus:TI (reg:TI 96)
                            (const_int 1 [0x1])))))
            (set (reg:TI 98)
                (plus:TI (reg:TI 96)
                    (const_int 1 [0x1])))
        ]) "pr93376.c":8:10 223 {*addvti4_doubleword_1}
     (expr_list:REG_UNUSED (reg:TI 98)
        (expr_list:REG_DEAD (reg:TI 96)
            (nil))))
and i2:
(insn 17 37 18 2 (set (reg:TI 96)
        (const_wide_int 0x7fffffffffffffffffffffffffffffff)) "pr93376.c":8:10 65 {*movti_internal}
     (nil))
the eq in there gets simplified into:
(eq:CCO (const_wide_int 0x080000000000000000000000000000000)
    (const_wide_int 0x80000000000000000000000000000000))
and simplify-rtx.c tries to simplify it by simplifying MINUS
of the two operands.
Now, i386 defines MAX_BITSIZE_MODE_ANY_INT to 128, because OImode
and XImode are used mainly as a placeholder for the vector modes;
these new signed overflow patterns are an exception to that,
but what they really need is just TImode precision + 1 (maybe 2 worst case)
bits at any time.

wide-int.h defines WIDE_INT_MAX_ELTS in a way that it contains one more
HWI above number of HWIs to cover WIDE_INT_MAX_ELTS, so on i386 that is
3 HWIs, meaning that TImode precision + 1/2 bits is still representable in
there.  Unfortunately, the way wi::sub_large is implemented, it needs
not just those 3 HWIs, but one HWI above the maximum of the lengths of
both operands, which means it buffer overflows, overwrites the following
precision in wide_int_storage and ICEs later on.  The need for 4 HWIs is
only temporary, because canonize immediately after it canonicalizes it
back to 3 HWIs only.

The patch is something suggested by Richard S., avoid using OImode
for this and instead use a partial int mode that is smaller.

    • libstdc++: Simplify makefile rule for largefile-config.h (PR91947) · 04681fca 
      The previous rule could leave an incomplete file if the build was
interrupted, which would then not be remade if make was run again.

This makes the rule more robust by writing to a temporary file and only
moving it into place as the final step. It also simplifies the rule so
that only the essential macro definitions are written to the file, not
the explanatory comments and commented out #undef lines.

Also, the macro for enabling LFS on Mac OS X 10.5 is now set
unconditionally, which is a bug fix from upstream autoconf.

	PR libstdc++/91947
	* include/Makefile.am (${host_builddir}/largefile-config.h): Simplify
	rule.
	* include/Makefile.in: Regenerate.

    • aarch64: Fix -mtrack-speculation for irreversible conditions [PR93341] · 2214053f 
      We can't yet represent the inverse of all conditions in rtl
(see g:865257c4), triggering an ICE in the pass
that handles -mtrack-speculation.  Since we don't expect these
insns to be optimised in any way, the easiest fix seemed to be
to add an insn that reverses the condition internally.

    • i386: Use bzhi for x & ((1 << y) - 1) or x & ((1U << y) - 1) [PR93346] · 9592f639 
      The bzhi patterns are quite complicated because they need to accurately
describe the behavior of the instruction for all input values.
The following patterns are simple and make bzhi recognizable even for
cases where not all input values are valid, because the user used
a shift, in which case the low 8 bit of the last operand need to be in
between 0 and precision-1.

into:

    • gotest: explicitly skip type descriptors · 92bea423 
      Type descriptors are normally weak and nm will report them as V,
so we will skip them when collecting the list of symbols.
But when not using GNU nm, they may be reported as D,
so also skip them in symstogo.

This fixes go/doc/check on Solaris.

    • analyzer: fix ICE due to sm-state origin being purged (PR 93382) · 591b59eb 
      The ICE in PR analyzer/93382 is a validation error.

The global variable "idx" acquires a "tainted" state from local array
n1[0].  When the frame is popped, the svalue for n1[0] is purged, but
the "taint" sm_state_map's entry for "idx" has a svalue_id referencing
the now-purged svalue.  This is caught by program_state::validate as an
assertion failure.

This patch fixes the issue by resetting the origin id within
sm_state_map entries for the case where the origin id has been purged.

gcc/analyzer/ChangeLog:
	PR analyzer/93382
	* program-state.cc (sm_state_map::on_svalue_purge): If the
	entry survives, but the origin is being purged, then reset the

    • analyzer: fix setjmp handling with -g (PR 93378) · fd9982bb 
      PR analyzer/93378 reports an ICE at -O1 -g when analyzing a rewind via
longjmp to a setjmp call with.

The root cause is that the rewind_info_t::get_setjmp_call attempts to
locate the setjmp GIMPLE_CALL via within the exploded_node containing
it, but the exploded_node has two stmts: a GIMPLE_DEBUG, then the
GIMPLE_CALL, and so erroneously picks the GIMPLE_DEBUG, leading to
a failed as_a <const gcall *>.

This patch reworks how the analyzer stores information about a setjmp
so that instead of storing an exploded_node *, it instead introduces
a "setjmp_record" struct, for use by both setjmp_svalue and
rewind_info_t.  Hence we store the information directly, rather than
attempting to reconstruct it, fixing the bug.

    • PR c++/92907 - noexcept does not consider "const" in member functions. · e1fd0408 
      Here the problem is that if the noexcept specifier is used in the context

leading to a bogus error.  g's const makes its 'this' const, so the first
overload of f should be selected.

In cp_parser_noexcept_specification_opt we inject 'this', but always
unqualified:

25738             inject_this_parameter (current_class_type, TYPE_UNQUALIFIED);
so we need to pass the function's qualifiers down here.  In
cp_parser_direct_declarator it's easy: use the just parsed cv_quals, in
cp_parser_late_noexcept_specifier look at the 'this' parameter to figure it
out.

    • cfgexpand: Update partition size when merging variables · 7c46e71d 
      cfgexpand sorts variables by decreasing size, so when merging a later
variable into an earlier one, there's usually no need to update the
merged size.

But for poly_int sizes, the sort function just uses a lexicographical
comparison of the coefficients, so e.g. 2X+2 comes before 0X+32.
Which is bigger depends on the runtime value of X.

This patch therefore takes the upper bound of the two sizes, which
is conservatively correct for variable-length vectors and a no-op
on other targets.

It's probably a bad idea to merge fixed-length and variable-length
variables in practice, but that's really an optimisation decision.
I think we should have this patch as a correctness fix either way.

This is easiest to test using the ACLE, but in principle it could happen
for autovectorised code too, e.g. when using OpenMP vector variables.
It's therefore a regression from GCC 8.

    • aarch64: Fix aarch64_expand_subvti constant handling [PR93335] · d80f0a8d 
      The two patterns that call aarch64_expand_subvti ensure that {low,high}_in1
is a register, while {low,high}_in2 can be a register or immediate.
subdi3_compare1_imm uses the aarch64_plus_immediate predicate for its last
two operands (the value and negated value), but aarch64_expand_subvti calls
it whenever low_in2 is a CONST_INT, which leads to ICEs during vregs pass,
as the emitted insn is not recognized as valid subdi3_compare1_imm.
The following patch fixes that by only using subdi3_compare1_imm if it is ok
to do so, and otherwise force the constant into register and use the
non-immediate version - subdi3_compare1.
Furthermore, previously the code was calling force_reg on high_in2 only if
low_in2 is CONST_INT, on the (reasonable) assumption is that only if low_in2
is a CONST_INT, high_in2 can be non-REG, but with the above changes even in
the else we might have CONST_INT and force_reg doesn't do anything if the
operand is already a REG, so this patch calls it unconditionally.
