PR libstdc++/78420 Make std::less etc. yield total order for pointers

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
operator with pointer operands, and dispatch that case to the
corresponding specialization for void pointers.

David Malcolm [Wed, 14 Mar 2018 13:58:13 +0000 (13:58 +0000)]
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).

Palmer Dabbelt [Tue, 13 Mar 2018 18:35:06 +0000 (18:35 +0000)]
RISC-V: Add and document the "-mno-relax" option

RISC-V relies on aggressive linker relaxation to get good code size.  As
a result no text symbol addresses can be known until link time, which
means that alignment must be handled during the link.  This alignment
pass is essentially just another linker relaxation, so this has the
unfortunate side effect that linker relaxation is required for
correctness on many RISC-V targets.

The RISC-V assembler has supported an ".option norelax" for a long time
because there are situations in which linker relaxation is a bad idea --
the canonical example is when trying to materialize the initial value of
the global pointer into a register, which would otherwise be relaxed to
a NOP.  We've been relying on users who want to disable relaxation for
an entire link to pass "-Wl,--no-relax", but that still relies on the
linker relaxing R_RISCV_ALIGN to handle alignment despite it not being
strictly necessary.

This patch adds a GCC option, "-mno-relax", that disable linker
relaxation by adding ".option norelax" to the top of every generated
assembly file.  The assembler is smart enough to handle alignment at
assemble time for files that have never emitted a relaxable relocation,
so this is sufficient to really disable all relaxations in the linker,
which results in significantly faster link times for large objects.

This also has the side effect of allowing toolchains that don't support
linker relaxation (LLVM and the Linux module loader) to function
correctly.  Toolchains that don't support linker relaxation should
default to "-mno-relax" and error when presented with any R_RISCV_ALIGN
relocation as those need to be handled for correctness.

6 years ago[SLP/AArch64] Fix unpack handling for big-endian SVE
Richard Sandiford [Tue, 13 Mar 2018 15:13:37 +0000 (15:13 +0000)]
[SLP/AArch64] Fix unpack handling for big-endian SVE

I hadn't realised that on big-endian targets, VEC_UNPACK*HI_EXPR unpacks
the low-numbered lanes and VEC_UNPACK*LO_EXPR unpacks the high-numbered
lanes.  This meant that both the SVE patterns and the handling of
fully-masked loops were wrong.

The patch deals with that by making sure that all vec_unpack* optabs
are define_expands, using BYTES_BIG_ENDIAN to choose the appropriate
define_insn.  This in turn meant that we can get rid of the duplication
between the signed and unsigned patterns for predicates.  (We provide
implementations of both the signed and unsigned optabs because the sign
doesn't matter for predicates: every element contains only one
significant bit.)

Also, the float unpacks need to unpack one half of the input vector,
but the unpacked upper bits are "don't care".  There are two obvious
ways of handling that: use an unpack (filling with zeros) or use a ZIP
(filling with a duplicate of the low bits).  The code previously used
unpacks, but the sequence involved a subreg that is semantically an
element reverse on big-endian targets.  Using the ZIP patterns avoids
that, and at the moment there's no reason to prefer one over the other
for performance reasons, so the patch switches to ZIP unconditionally.
As the comment says, it would be easy to optimise this later if UUNPK
turns out to be better for some implementations.

6 years ago[AArch64] Add a tlsdesc call pattern for SVE
Richard Sandiford [Tue, 13 Mar 2018 15:12:59 +0000 (15:12 +0000)]
[AArch64] Add a tlsdesc call pattern for SVE

tlsdesc calls are guaranteed to preserve all Advanced SIMD registers,
but are not guaranteed to preserve the SVE extension of them.
The calls also don't preserve the SVE predicate registers.

The long-term plan for handling the SVE vector registers is CLOBBER_HIGH,
which adds a clobber equivalent of TARGET_HARD_REGNO_CALL_PART_CLOBBERED.
The pattern can then directly model the fact that the low 128 bits are
preserved and the upper bits are clobbered.

However, it's too late now for that to be included in GCC 8, so this
patch conservatively treats the whole vector register as being clobbered.
This has the obvious disadvantage that compiling for SVE can make NEON
code worse, but I don't think there's much we can do about that until
CLOBBER_HIGH is in.

rs6000: sysv: Don't pass SFmode in varargs in FPRs

This makes the float32-basic.c testcase work on sysv (32-bit Linux).

"float" is promoted to "double" for varargs.  The ABI also only defines
the use of double precision in varargs.  But _Float32 is not promoted.
Since there is no way of passing single-precision float in FPRs we
should pass SFmode in GPRs (or memory) instead.  This is similar to
the 64-bit ABI.

There still are situations where we have stale LOG_LINKS.  This causes
combine to try two-insn combinations I2->I3 where the register set by
I2 is used before I3 as well.  Not good.
