Bug#907507: coreutils: /bin/dd throws a sig fault in mutex_optimistic_spin+0x164/0x1b0
Package: coreutils Version: 8.26-3 Severity: normal Dear Maintainer, *** Reporter, please consider answering these questions, where appropriate *** * What led up to the situation? Attempt to kill -9 $pid for a process running dd * What exactly did you do (or not do) that was effective (or ineffective)? Could not kill the process as it seemed hung. I pulled the USB memory stick out of the machine. * What was the outcome of this action? At some point later the process died as "killed" and the shell prompt was visible. * What outcome did you expect instead? Expect a normal process to stop when CTRL-C or a kill -9 is issued.

Bug#895452: libquadmath and quadmath.h do not exist on ppc64
I will test gcc-8-20180415 and see what results I get.
Bug#895452: libquadmath and quadmath.h do not exist on ppc64
New GCC bigid is being flipped around by Jakub Jelinek ( Red Hat ) who claims this issue is fixed for ppc64 in GCC version 8 that does not exist anywhere. Not even in the git repo. I am trying to figure out what is going on here. see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82686 see https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85440 What a mess .. seems like a new secret gcc codebase exists somewhere and no one can see it.

Bug#895452: some progress bootstrap completes for gcc 7.3.0
Managed a bootstrap that didn't blow up. At the moment the assembly output from a trivial test shows that the IBM extended precision long double type is the default unless one actually asks for the IEEE754-2008 128-bit datatype. dclarke@nix:~/pgm/C/ieee754$ PATH=/usr/local/build/gcc-7.3.0_linux_4.15.0-2-powerpc64_ppc64.005/gcc:$PATH xgcc -I/usr/local/build/gcc-7.3.0_linux_4.15.0-2-powerpc64_ppc64.005/gcc/include -m64 -g -Wl,-rpath=/usr/local/lib -mcpu=970 -maltivec -mfull-toc -mregnames -mabi=ieeelongdouble -S -o ld.s ld.c xgcc: warning: using IEEE extended precision long double cc1: warning: using IEEE extended precision long double dclarke@nix:~/pgm/C/ieee754$ grep "quad" ld.s | grep "0x" .quad 0x4000921fb54442d1,0x8469898cc51701b8 That data is correct. dclarke@nix:~/pgm/C/ieee754$ PATH=/usr/local/build/gcc-7.3.0_linux_4.15.0-2-powerpc64_ppc64.005/gcc:$PATH xgcc -I/usr/local/build/gcc-7.3.0_linux_4.15.0-2-powerpc64_ppc64.005/gcc/include -m64 -g -Wl,-rpath=/usr/local/lib -mcpu=970 -maltivec -mfull-toc -mregnames -mabi=ibmlongdouble -S -o ld.s ld.c xgcc: warning: using IBM extended precision long double cc1: warning: using IBM extended precision long double dclarke@nix:~/pgm/C/ieee754$ grep "quad" ld.s | grep "0x" .quad 0x400921fb54442d18,0x3ca1a62633145c06 That is a whole other beast of a different colour. dclarke@nix:~/pgm/C/ieee754$ PATH=/usr/local/build/gcc-7.3.0_linux_4.15.0-2-powerpc64_ppc64.005/gcc:$PATH xgcc -I/usr/local/build/gcc-7.3.0_linux_4.15.0-2-powerpc64_ppc64.005/gcc/include -m64 -g -Wl,-rpath=/usr/local/lib -mcpu=970 -maltivec -mfull-toc -mregnames -S -o ld.s ld.c dclarke@nix:~/pgm/C/ieee754$ grep "quad" ld.s | grep "0x" .quad 0x400921fb54442d18,0x3ca1a62633145c06 dclarke@nix:~/pgm/C/ieee754$ So the default is the IBM type.

Please could you check that again with a native build and a cross build, if you have access to a ppc64 platform? I am working on it. I need to get past some new silly dependency that makes little sense given that the bootstrap fails in stage 3 of all places : https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82686 So I should ( in theory ) be able to build the gc code in place and in the tree in the same manner as gmp, mpfr, mpc and isl. So I am working on that but it just isn't working. In any case I'll get the sources from http://www.hboehm.info/gc/ and keep hacking at this on ppc64. Dennis
