Fwd: [Bug web/82686] Debian sid powerpc64-unknown-linux-gnu 4.13.0-1-powerpc64 bootstrap breaks in stage3 with unexpected requirement for bdw-gc





Merely an FYI ... the word on the street is that GCC 8 will provide a
solid implementation of libquadmath to ppc64.  We also know that the
newer IBM Power line will have some hardware implementation for the
new 128-bit floating point type.  Not sure if anyone else is thrilled
by this but for me big sparc has been the only way to get that level
of floating point working.  Namely Solaris because libquadmath code is
all based on the original SunPro code that went into Solaris.

see http://src.illumos.org/source/xref/illumos-gate/usr/src/lib/libm/common/LD/sinl.c

see https://github.com/gcc-mirror/gcc/blob/master/libquadmath/math/sinq.c

In any case I hope to see this works cross platform on sparc and ppc64
and also perhaps on PA-Risc as I have a few superdomes on hand.

I have gcc-8-20180415 boot strapping now with the gcc 7.3.0 I had built
just yesterday :

Even better results on Solaris 10 sparc :

https://gcc.gnu.org/ml/gcc-testresults/2018-04/msg01455.html

Note that a better GNU make with modern glibc is needed to get past
 stage 1 and the patches are available :

http://lists.gnu.org/archive/html/bug-make/2018-04/msg00018.html

Works flawlessly on RHEL 7.4 x86_64 and PPC64 and SPARC64.

I should followup with gcc 8-beta results shortly.

Dennis

ps: is anyone else having fun with this or just me ?
