6 years agopoly_int: rtx constants
Richard Sandiford [Wed, 20 Dec 2017 12:51:36 +0000 (12:51 +0000)]
poly_int: rtx constants

This patch adds an rtl representation of poly_int values.
There were three possible ways of doing this:

(1) Add a new rtl code for the poly_ints themselves and store the
    coefficients as trailing wide_ints.  This would give constants like:

      (const_poly_int [c0 c1 ... cn])

    The runtime value would be:

      c0 + c1 * x1 + ... + cn * xn

(2) Like (1), but use rtxes for the coefficients.  This would give
    constants like:

      (const_poly_int [(const_int c0)
                       (const_int c1)
                       ...
                       (const_int cn)])

    although the coefficients could be const_wide_ints instead
    of const_ints where appropriate.

(3) Add a new rtl code for the polynomial indeterminates,
    then use them in const wrappers.  A constant like c0 + c1 * x1
    would then look like:

      (const:M (plus:M (mult:M (const_param:M x1)
                               (const_int c1))
                       (const_int c0)))

There didn't seem to be that much to choose between them.  The main
advantage of (1) is that it's a more efficient representation and
that we can refer to the cofficients directly as wide_int_storage.

Add a gen_int_shift_amount helper function

This patch adds a helper routine that constructs rtxes
for constant shift amounts, given the mode of the value
being shifted.  As well as helping with the SVE patches, this
is one step towards allowing CONST_INTs to have a real mode.

One long-standing problem has been to decide what the mode
of a shift count should be for arbitrary rtxes (as opposed to those
directly tied to a target pattern).  Realistic choices would be
the mode of the shifted elements, word_mode, QImode, a 64-bit mode,
or the same mode as the shift optabs (in which case what should the
mode be when the target doesn't have a pattern?)

For now the patch picks a 64-bit mode, but with a ??? comment.

[arm] PR target/83105: Minor change of default CPU for arm-linux-gnueabi

When GCC for ARM/linux is configured with --with-float=hard, or
--with-float=softfp the compiler will now die when trying to build the
support libraries because the baseline architecture is too old to
support VFP (older versions of GCC just emitted the VFP instructions
anyway, even though they wouldn't run on that version of the
architecture; but we're now more prickly about it).

This patch fixed the problem by raising the default architecture
(actually the default CPU) to ARMv5te (ARM10e) when we need to generate
HW floating-point code.

As has been spotted at https://gcc.gnu.org/ml/gcc-patches/2017-12/msg01289.html
we check the __AARCH64EB__ macro for aarch64 big-endian
detection in config/cpu/aarch64/opt/ext/opt_random.h.
That works just fine with GCC but the standardised ACLE[1] macro
for that purpose is __ARM_BIG_ENDIAN so there is a possibility
that non-GCC compilers that include this header are not aware
of this predefine.

So this patch changes the use of __AARCH64EB__ to
the more portable __ARM_BIG_ENDIAN.

Tested on aarch64-none-elf and aarch64_be-none-elf.

[arm] PR target/82975: Guard against reg_renumber being NULL in arm.h

In this bug we ICE when checking REGNO_OK_FOR_INDEX_P on arm during pre-IRA scheduling.
This is because REGNO_OK_FOR_INDEX_P ends up checking the reg_renumber array.
Before IRA reg_renumber is NULL and thus we segfault.

The fix is to guard the use of reg_renumber in the logic in TEST_REGNO in arm.h.
On aarch64, for example, we also guard against the reg_renumber == NULL case.
This fixes the ICE. I also remove the part of the comment that muses on when reg_renumber
is available as with this patch it should now be safe to use at any point.

Bootstrapped and tested on arm-none-linux-gnueabihf.

David Malcolm [Mon, 18 Dec 2017 19:23:30 +0000 (19:23 +0000)]
testsuite: add coverage for diagnostics relating to inlining (PR tree-optimization/83336)

In theory, the diagnostics subsystem can print context information on
code inlining when diagnostics are emitted by the middle-end, describing
the chain of inlined callsites that led to a particular warning,
but PR tree-optimization/83336 describes various issues with this.

An underlying issue is that we have very little automated testing for
this code: gcc.dg/tm/pr52141.c has a test, but in general, prune.exp
filters out the various "inlined from" lines.

The following patch adds test coverage for it for C and C++ via a new
testsuite plugin, which emits a warning from the middle-end; the test
cases use dg-regexp to verify that the "inlined from" lines are
emitted correctly, with the correct function names and source locations.

Doing so requires a change to prune.exp: the dg-regexp lines have to
be handled *before* the "inlined from" lines are stripped.

gcc/testsuite/ChangeLog:

Add a gen_int_shift_amount helper function

This patch adds a helper routine that constructs rtxes
for constant shift amounts, given the mode of the value
being shifted.  As well as helping with the SVE patches, this
is one step towards allowing CONST_INTs to have a real mode.

One long-standing problem has been to decide what the mode
of a shift count should be for arbitrary rtxes (as opposed to those
directly tied to a target pattern).  Realistic choices would be
the mode of the shifted elements, word_mode, QImode, or the same
mode as the shift optabs (in which case what should the mode
be when the target doesn't have a pattern?)

For now the patch picks the mode of the shifted elements,
but with a ??? comment.

Minor vn_reference_lookup_3 tweak

The repeated checks for MEM_REF made this code hard to convert to
poly_ints as-is.  Hopefully the new structure also makes it clearer
at a glance what the two cases are.

Add VEC_DUPLICATE_EXPR and associated optab

SVE needs a way of broadcasting a scalar to a variable-length vector.
This patch adds VEC_DUPLICATE_EXPR for when CONSTRUCTOR would be used
