Subject: Ping #2: [PATCH 0/9] PowerPC: Patches to enable changing the long double default to IEEE 128-bit on little endian PowerPC 64-bit Linux systems
Date: Fri, 16 Oct 2020 10:37:39 -0400 [thread overview]
Message-ID: <20201016143739.GA29167@ibm-toto.the-meissners.org> (raw)
In-Reply-To: <20200924202036.GA28437@ibm-toto.the-meissners.org>
Ping (#2) the following 9 patches to add support for building a GCC toolchain
where the default long double is IEEE 128-bit floating point instead of the IBM
extended double floating point.
The first patch was revised with input from Joesph Myers. I will list that
patch in this list. Most of these patches are independent of each other, so if
there are problems with some of the patches, please look at the other patches
after that patch:
Patch #1: Map built-in long double functions to an alternate name if long
double is IEEE 128-bit.
https://gcc.gnu.org/pipermail/gcc-patches/2020-October/555855.html
Patch #2: Update error messages about mixing __float128 and __ibm128 to deal
with long double being IEEE 128-bit:
https://gcc.gnu.org/pipermail/gcc-patches/2020-September/554767.html
Patch #3: Rework libgcc 128-bit floating point conversion support:
https://gcc.gnu.org/pipermail/gcc-patches/2020-September/554768.html
Patch #4: Add support in libgcc to convert between IEEE 128-bit and the three
Decimal types:
https://gcc.gnu.org/pipermail/gcc-patches/2020-September/554770.html
Patch #5: Fix some tests that break if long double is IEEE 128-bit:
https://gcc.gnu.org/pipermail/gcc-patches/2020-September/554772.html
Patch #6: Map the 'q' built-ins to 'l' built-ins if long double is IEEE
128-bit:
https://gcc.gnu.org/pipermail/gcc-patches/2020-September/554773.html
Patch #7: Update the power10 built-in functions for IEEE 128-bit support to
support long double if long double is IEEE 128-bit:
https://gcc.gnu.org/pipermail/gcc-patches/2020-September/554774.html
Patch #8: Change tests that use an explicit '__ieee128' keywork to use the
keyword we document ('__float128'):
https://gcc.gnu.org/pipermail/gcc-patches/2020-September/554775.html
Patch #9: If long double is IEEE 128-bit, use the pack_ibm128 built-in instead
of the pack_longdouble built-in in libgcc:
https://gcc.gnu.org/pipermail/gcc-patches/2020-September/554776.html
