Subject: [PATCH 0/4] Fixes for `const_double_zero' use + VAX iterator simplification
Date: Fri, 8 Jan 2021 01:50:01 +0000 (GMT) [thread overview]
Message-ID: <alpine.LFD.2.21.2101072204040.1637534@eddie.linux-mips.org> (raw)
Hi,
This patch series fixes an issue with `const_double_zero' use causing a
build failure reported with the `pdp11-aout' target by Martin Liška:
<https://gcc.gnu.org/pipermail/gcc-patches/2020-December/561896.html>
superseding an earlier proposal discussed here:
<https://gcc.gnu.org/pipermail/gcc-patches/2020-December/561972.html>.
I have decided to split the fix into pieces so as to have targets bits as
separate changes in order to make possible backports easier.
In the course of investigation I have noticed a VAX iterator attribute I
have recently introduced duplicates the standard `mode' attribute
unnecessarily so I have decided to remove it along with the fix; it has a
syntactic dependency on 3/4, so it has to be a part of the series.
See individual changes for detailed descriptions.
These changes have been regression-tested with the `vax-netbsdelf' target
and verified manually with the `pdp11-aout' target. For 4/4 I have also
verified that no change has been made to target library code produced.
OK to apply?
Maciej
