Sudakshina Das [Mon, 19 Mar 2018 18:50:32 +0000 (18:50 +0000)]
[PR81647][AARCH64] Fix handling of Unordered Comparisons in aarch64-simd.md

This patch fixes the inconsistent behavior observed at -O3 for the unordered
comparisons. According to the online docs (https://gcc.gnu.org/onlinedocs
/gcc-7.2.0/gccint/Unary-and-Binary-Expressions.html), all of the following
should not raise an FP exception:
- UNGE_EXPR
- UNGT_EXPR
- UNLE_EXPR
- UNLT_EXPR
- UNEQ_EXPR
Also ORDERED_EXPR and UNORDERED_EXPR should only return zero or one.

The aarch64-simd.md handling of these were generating exception raising
instructions such as fcmgt. This patch changes the instructions that are
emitted in order to not give out the exceptions. We first check each
operand for NaNs and force any elements containing NaN to zero before using
them in the compare.

Example: UN<cc> (a, b) -> UNORDERED (a, b)
  | (cm<cc> (isnan (a) ? 0.0 : a, isnan (b) ? 0.0 : b))

The ORDERED_EXPR is now handled as (cmeq (a, a) & cmeq (b, b)) and
UNORDERED_EXPR as ~ORDERED_EXPR and UNEQ as (~ORDERED_EXPR | cmeq (a,b)).

libgo: add runtime/pprof/internal/profile.gox to noinst_DATA

    Also add noinst_DATA to CHECK_DEPS; it's not needed in practice since
    `make` will build noinst_DATA, but it's logically required and will
    make a difference if any of the noinst_DATA sources change between

    Tony Reix figured out why omitting packages from noinst_DATA didn't
    seem to matter: because if gccgo can't find foo.gox, it will fall back
    to reading the export data in foo.o, and foo.o will exist because

In order for std::less<T*> etc. to meet the total order requirements of
[comparisons] p2 we need to cast unrelated pointers to uintptr_t before
comparing them. Those casts aren't allowed in constant expressions, so
only cast when __builtin_constant_p says the result of the comparison is
not a compile-time constant (because the arguments are not constants, or
the result of the comparison is unspecified). When the result is
constant just compare the pointers directly without casting.

This ensures that the function can be called in constant expressions
with suitable arguments, but still yields a total order even for
otherwise unspecified pointer comparisons.

For std::less<void> etc. add new overloads for pointers, which use
std::less<common_type_t<T*,U*>> directly. Also change the generic
overloads to detect when the comparison would call a built-in relational

Fix ICE for missing header fix-it hints with overlarge #line directives (PR c/84852)

PR c/84852 reports an ICE inside diagnostic_show_locus when printing
a diagnostic for a source file with a #line >= 2^31:

  #line 7777777777
  int foo (void) { return strlen(""); }

where we're attempting to print a fix-it hint at the top of the file
and underline the "strlen" (two "line spans").

The
  #line 7777777777
won't fix within the 32-bit linenum_type, and is truncated from
  0x1cf977871
to
   0xcf977871
i.e. 3482810481 in decimal.

Such a #line is reported by -pedantic and -pedantic-errors, but we
shouldn't ICE.

The ICE is an assertion failure within layout::calculate_line_spans,
where the line spans have not been properly sorted.

The layout_ranges are stored as int, rather than linenum_type,
giving line -812156815 for the error, and line 1 for the fix-it hint.

However, line_span uses linenum_type rather than int.

line_span::comparator compares these values as int, and hence
decides that (linenum_type)3482810481 aka (int)-812156815 is less
than line 1.

This leads to this assertion failing in layout::calculate_line_spans:

1105       gcc_assert (next->m_first_line >= current->m_first_line);

since it isn't the case that 1 >= 3482810481.

The underlying problem is the mix of types for storing line numbers:
in parts of libcpp and diagnostic-show-locus.c we use linenum_type;
in other places (including libcpp's expanded_location) we use int.

I looked at using linenum_type throughout, but doing so turned into
a large patch, so this patch fixes the ICE in a less invasive way
by merely using linenum_type more consistently just within
diagnostic-show-locus.c, and fixing line_span::comparator to properly
handle line numbers (and line number differences) >= 2^31, by using
a new helper function for linenum_type differences, computing the
difference using long long, and using the sign of the difference
(as the difference might not fit in the "int" return type imposed
by qsort).
