package/gcc: remove version 6.5
gcc 9.1 is around, gcc 8.3 is the default version, so drop 6.5 in order to reduce the gcc choice. Keep gcc 5.5 since it still used by beaglebone_qt5_defconfig. Signed-off-by: Romain Naour <romain.naour@smile.fr> Signed-off-by: Peter Korsgaard <peter@korsgaard.com>2019.08.x

Subject: [PATCH] gcc: xtensa: don't force PIC for uclinux target
|
||||
|
||||
xtensa-uclinux uses bFLT executable file format that cannot relocate
|
||||
fields representing offsets from data to code. C++ objects built as PIC
|
||||
use offsets to encode FDE structures. As a result C++ exception handling
|
||||
doesn't work correctly on xtensa-uclinux. Don't use PIC by default on
|
||||
xtensa-uclinux.

|

When building against uClibc with wchar support disabled, WCHAR_MIN and

WCHAR_MAX are not defined leading to compilation errors.
|

Fix it by only including the wchar code if available.

|
||||
Subject: [PATCH] Make MicroBlaze support DWARF EH (old Xilinx patch, needed
|
||||
for glibc build).
|
||||
|
||||
This patch, taken from
|
||||
<https://git.busybox.net/buildroot/tree/package/gcc/5.4.0/840-microblaze-enable-dwarf-eh-support.patch>
|
||||
and with a few formatting cleanups and an update for the removal of
|
||||
gen_rtx_raw_REG, enables DWARF EH support for MicroBlaze.
|
||||
|
||||
This is needed for building glibc with a compiler that includes shared
|
||||
libgcc; right now all glibc builds for MicroBlaze are failing with my
|
||||
bot for lack of this support. (It's dubious if we should have glibc
|
||||
ports at all where required support is missing in FSF GCC.)
|
||||
|
||||
Tested building glibc with build-many-glibcs.py. I have *not* done
|
||||
any other testing or any execution testing for MicroBlaze.

||||
