Bug#852091: gcc-6: Binaries compiled with gccgo on m68k crash (unaligned access)
Source: gcc-6
Version: 6.3.0-3
Severity: normal
Tags: patch
User: debian-...@lists.debian.org
Usertags: m68k
Hi!
The attached patch is a backport of the fix provided by upstream to fix
gccgo on m68k [1]. I have added this patch to gcc-6_6.3.0-3, rebuild the
package and verified gccgo now produces working binaries.
Of course, if upstream decides to backport this patch to gcc-6, it won't
be necessary to carry this patch in gcc-6. But in case that doesn't happen,
here's a patch verified to be working to be applied instantly.
Thanks,
Adrian

Bug#852104: g++-7 fails to include standard include path
Package: g++-7
Version: 7-20170118-1
Severity: important
The latest gcc-7 experimental snapshot appears to be missing
'/usr/include/g++/7' from the standard include search paths, and as a
result can't compile anything using any stl headers, e.g.:
#include
int main() {}
fails to compile with:
test.cpp:1:10: fatal error: iostream: No such file or directory
#include
^~
compilation terminated.
Running cpp-7 -E -x c++ -v gives me:

Package: g++-7
Version: 7-20170118-1
Severity: important
The latest gcc-7 experimental snapshot appears to be missing
'/usr/include/g++/7' from the standard include search paths, and as a
result can't compile anything using any stl headers, e.g.:
#include
int main() {}
fails to compile with:
test.cpp:1:10: fatal error: iostream: No such file or directory
#include
^~
compilation terminated.
Running cpp-7 -E -x c++ -v gives me:

Bug#852153: gcc-6/mips: backport option to disable madd4 instructions and set it default
Package: src:gcc-6
Version: 6.3.0-3
Hi, gcc-7 has added a new option to disable madd.fmt/msub.fmt etc instructions,
as
1. For the MIPS standard, these instructions are unfused, while on Loongson,
they are fused. With these instructions enabled, some software
may failed to
run on Loongson.
2. With some test, these instructions won't take significant
performance boost.
So, we decide to disable these instructions at all.
In this patch, we also:
1. generate fused madd4 instructions when -march=loongson3a used.
2. add a new option: -mlxc1-sxc1.
