compiler: lower expression types in lowering pass

    Ensure that array types with complicated length expressions are
    handled correctly by lowering expression types in the lowering pass.

    This required some adjustment of constant expression types to not
    report too many errors for circular constant expressions.  We now
    record error types in the Named_constant type.  If we find the
    circularity due to lowering the Named_constant, we use that location
    for the error message; this retains the error location we used to use.

[AArch64] Fix sve/extract_[12].c for big-endian SVE

sve/extract_[12].c were relying on the target-independent optimisation
that removes a redundant vec_select, so that we don't end up with
things like:

    dup v0.4s, v0.4s[0]
    ...use s0...

But that optimisation rightly doesn't trigger for big-endian targets,
because GCC expects lane 0 to be in the high part of the register
rather than the low part.

SVE breaks this assumption -- see the comment at the head of
aarch64-sve.md for details -- so the optimisation is valid for
both endiannesses.  Long term, we probably need some kind of target
hook to make GCC aware of this.

But there's another problem with the current extract pattern: it doesn't
tell the register allocator how cheap an extraction of lane 0 is with
tied registers.  It seems better to split the lane 0 case out into
its own pattern and use tied operands for the FPR<-SIMD case,
so that using different registers has the cost of an extra reload.
I think we want this for both endiannesses, regardless of the hook
described above.

Also, the gen_lowpart in this pattern fails for aarch64_be due to
TARGET_CAN_CHANGE_MODE_CLASS restrictions, so the patch uses gen_rtx_REG
instead.  We're only creating this rtl in order to print it, so there's
no need for anything fancier.

6 years agoFix LRA subreg calculation for big-endian targets
Richard Sandiford [Tue, 30 Jan 2018 09:45:58 +0000 (09:45 +0000)]
Fix LRA subreg calculation for big-endian targets

LRA was using a subreg offset of 0 whenever constraints matched
two operands with different modes.  That leads to an invalid offset
(and ICE) on big-endian targets if one of the modes is narrower
than a word.  E.g. if a (reg:SI X) is matched to a (reg:QI Y),
the big-endian subreg should be (subreg:QI (reg:SI X) 3) rather
than (subreg:QI (reg:SI X) 0).

But this raises the issue of what the behaviour should be when the
matched operands occupy different numbers of registers.  Should the
register numbers match, or should the locations of the lsbs match?
Although the documentation isn't clear, reload went for the second
interpretation (which seems the most natural to me):

      /* On a REG_WORDS_BIG_ENDIAN machine, point to the last register of a
         multiple hard register group of scalar integer registers, so that
         for example (reg:DI 0) and (reg:SI 1) will be considered the same
         register.  */

So I think this means that we can/must use the lowpart offset
unconditionally, rather than trying to separate out the multi-register
case.  This also matches the LRA handling of constant integers, which
already uses lowpart subregs.

The patch fixes gcc.target/aarch64/sve/extract_[34].c for aarch64_be.

[AArch64] Fix gcc.target/aarch64/subs_compare_[12].c

This patch fixes the testsuite failures gcc.target/aarch64/subs_compare_1.c and subs_compare_2.c
The tests check that we combine a sequence like:
        sub     w2, w0, w1
        cmp     w0, w1

into
        subs    w2, w0, w1

This is done by a couple of peepholes in aarch64.md.

Unfortunately due to scheduling and other optimisations the SUB and CMP
can come in a different order:
        cmp     w0, w1
        sub     w0, w0, w1

And the existing peepholes cannot catch that and we fail to combine the two.
This patch adds a peephole that matches the CMP as the first insn and the SUB as the second
and outputs a SUBS.  This is almost equivalent to the existing peephole that matches SUB first and CMP second
except that it doesn't have the restriction that the output register of the SUB has to not be one of the input registers.
Remember "sub w0, w0, w1 ; cmp w0, w1" is *not* equivalent to: "subs  w0, w0, w1"
but "cmp w0, w1 ; sub w0, w0, w1" is.

So this is what this patch does. It adds a peephole for the case above and one for the SUB-immediate variant
(because the SUB-immediate is represented as PLUS-of-negated-immediate and thus has different RTL structure).

Bootstrapped and tested on aarch64-none-linux-gnu.

    * config/aarch64/aarch64.md: Add peepholes for CMP + SUB -> SUBS
    and CMP + SUB-immediate -> SUBS.
