I committed a patch to libgo to update the library to the first
release candidate of the upcoming Go 1.8 release. This is a big
update, mostly a straight copy of the code in the master Go library.
I made the following changes to the Go frontend to correspond to
changes in the runtime library:
* Change map assignment to use mapassign and assign value directly.
* Change string iteration to use decoderune, faster for ASCII strings.
* Change makeslice to take int, and use makeslice64 for larger values.
* Add new noverflow field to hmap struct used for maps.
There are two known problems that I simply commented out of test code
until they can be fixed:
* Commented out test in go/types/sizes_test.go that doesn't compile.
* Commented out reflect.TestStructOf test for padding after zero-sized field.
As usual with these sorts of updates the patch is too large to send to
the mailing list. I've appended the changes to the gccgo-specific
parts of the code.
Bootstrapped and ran Go testsuite on x86_64-pc-linux-gnu. I would not
be terribly surprised if this breaks Solaris. I'll try to check that
out shortly.

Same on Solaris. However, before I even get there, I hit
make[4]: *** No rule to make target 'golang_org/x/net/lif/lif.lo', needed by 'libgo.la'. Stop.
Fixed like this:

Thanks. I committed this patch, which I think should fix the problem.
Bootstrapped and ran Go testsuite on x86_64-pc-linux-gnu.

This seems to need a version of defs_solaris.go that works with the
constants and structs living in syscall.

Hi Ian,
> This seems to need a version of defs_solaris.go that works with the
> constants and structs living in syscall.
I've made some progress here: I need to check <sys/sockio.h> for
SIOCGLIF* ioctls, and <net/if_types.h> for the IFT_* constants. I've
updated configure.in and sysinfo.c accordingly, and adapted
defs_solaris.go as well. However, I still run into a number of errors:

The structs aren't exported yet, need handling in mksysinfo.sh, too, I

Why? GCC 6.x shipped with libgo.so.9, so I don't see anything wrong
on 7.x shipping libgo.so.10.

In the past, the libgo version number has always matched the Go version,
not the gcc release.
The libgo for Go 1.7 and Go 1.8 are not the same. If someone wanted to
build gccgo for Go 1.7 using an old commit
maybe for testing or comparison purposes, the libgo version would not
identify which one it was because
libgo.so.10 could be either Go 1.7 or 1.8. Maybe nobody cares about
doing that. It's not a huge deal to me but
it would be a point of confusion.
GCC 6.x was Go 1.6.

I committed this patch to fix the remaining build problems on Solaris.
Bootstrapped and ran some of the Go tests on i386-sun-solaris11 and
x86_64-pc-linux-gnu.

I do usually update the version number for each major import (and I do
usually forget to do it the first time around). I committed this
patch to mainline.
