Subject: [PATCH 05/11] libstdc++: Remove incorrect fabs overload
Date: Tue, 8 Jun 2021 14:11:39 +0200 [thread overview]
Message-ID: <3002364.OxmWWEHjG1@excalibur> (raw)
In-Reply-To: <270527782.u9WJ3AIrlG@excalibur>
[-- Attachment #1: Type: text/plain, Size: 1152 bytes --]
From: Matthias Kretz <kretz@kde.org>
fabs(int) returns double, this one didn't. This overload is not
specified in the Parallelism TS 2. Also remove the comment about labs
and llabs: it doesn't belong here.
Signed-off-by: Matthias Kretz <m.kretz@gsi.de>
libstdc++-v3/ChangeLog:
* include/experimental/bits/simd_math.h (fabs): Remove
fabs(simd<integral>) overload.
