6 years agoThis PR shows that we get the load/store_lanes logic wrong for arm big-endian.
Kyrylo Tkachov [Tue, 20 Mar 2018 17:13:16 +0000 (17:13 +0000)]
This PR shows that we get the load/store_lanes logic wrong for arm big-endian.

It is tricky to get right. Aarch64 does it by adding the appropriate lane-swapping
operations during expansion.

I'd like to do the same on arm eventually, but we'd need to port and validate the VTBL-generating
code and add it to all the right places and I'm not comfortable enough doing it for GCC 8, but I am keen
in getting the wrong-code fixed.
As I say in the PR, vectorisation on armeb is already severely restricted (we disable many patterns on BYTES_BIG_ENDIAN)
and the load/store_lanes patterns really were not working properly at all, so disabling them is not
a radical approach.

The way to do that is to return false in ARRAY_MODE_SUPPORTED_P for BYTES_BIG_ENDIAN.

Bootstrapped and tested on arm-none-linux-gnueabihf.
Also tested on armeb-none-eabi.

     PR target/82518
     * config/arm/arm.c (arm_array_mode_supported_p): Return false for
     BYTES_BIG_ENDIAN.

     * lib/target-supports.exp (check_effective_target_vect_load_lanes):

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
    `make` and `make check`.

    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
