[Buildroot] [PATCH] gcc: bump 7.x series to 7.2.0

[Buildroot] [PATCH] gcc: bump 7.x series to 7.2.0

[Thomas Petazzoni]

All patches continue to apply with no changes. 7.2.0 is a bugfix
release of the 7.x branch.

The only change that is not a simple bump is that the 7.2.0 tarball is
now available xz-compressed instead of bz2-compressed.

I'm not sure whether we want this for master or next. I've built 71
toolchains with GCC 7.2.0 for toolchains.free-electrons.com, the vast
majority of them being then used to build and boot a Linux kernel +
minimal userspace under Qemu.

Unfortunately, the tag gcc-7_2_0-release has still not appeared in
git://gcc.gnu.org/git/gcc.git, so it's hard to see the amount of
changes between gcc 7.1.0 and gcc 7.2.0.

According to the release e-mail at
https://gcc.gnu.org/ml/gcc/2017-08/msg00129.html:

"""
GCC 7.2 is a bug-fix release from the GCC 7 branch
containing important fixes for regressions and serious bugs in
GCC 6.1 with more than 95 bugs fixed since the previous release.
"""

Perhaps the safest is to take this in next.

I suspect this fixes real issues I've seen, including inability to
build systemd due to a GCC7 bug
(https://bugs.busybox.net/show_bug.cgi?id=10136) and some other GCC7
issues I've seen internally. I'll rebuild with this applied and verify
and then comment on the systemd build bug.

Rethinking this: gcc 7.x is not the default gcc version currently used
in Buildroot, so I think bumping the 7.x series to 7.2.0 is quite safe
for the 2017.08 release.

However, I don't really mind, so I'll let others give their opinion on
this.

Best regards,

Thomas

 master is fine for me.

 This is not maintainable, at some point we'll have to change it into
BR2_TOOLCHAIN_GCC_AT_LEAST_6.

Hi Thomas,

building this Kodi defconfig with your patch works:

BR2_x86_64=y
BR2_x86_core_avx2=y
BR2_TOOLCHAIN_BUILDROOT_LOCALE=y
BR2_GCC_VERSION_7_X=y
BR2_TOOLCHAIN_BUILDROOT_CXX=y
BR2_INIT_NONE=y
BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_EUDEV=y
# BR2_PACKAGE_BUSYBOX is not set
BR2_PACKAGE_KODI=y
BR2_PACKAGE_KODI_ALSA_LIB=y
BR2_PACKAGE_KODI_BLUEZ=y
BR2_PACKAGE_KODI_LIBBLURAY=y
BR2_PACKAGE_KODI_LIBCEC=y
BR2_PACKAGE_KODI_LIBVA=y
BR2_PACKAGE_MESA3D=y
BR2_PACKAGE_MESA3D_DRI_DRIVER_I965=y
BR2_PACKAGE_MESA3D_OPENGL_EGL=y
BR2_PACKAGE_XORG7=y
BR2_PACKAGE_PYTHON=y
BR2_PACKAGE_PYTHON_PY_ONLY=y

Imho you can commit your patch to the master branch.

Agreed, but I've kept that for a future change. In the future, most gcc
tarballs will be .tar.xz, so what we'll have to special case are the
older versions, not the newer ones :)
