2018-06-05Disable context functions for ThumbAlexey Neyman1-0/+1
They're written in ARM dialect, and `ldmia r14, {r14, pc}` is not accepted in T2 encoding. GCC8 changed the list of multilibs for arm-*, which now includes a variant with CPU that supports T2 but not A1 encoding. Signed-off-by: Alexey Neyman <stilor@att.net>

Add support and sample for uclibc multilib toolchain for ARC
2018-05-21ARC: Update Linux samplesAlexey Brodkin4-12/+2
There's no point in keeping samples which are in its essense just a sub-set of multilib toolchain. But still we'd like to cover quite unusual but really existing case - ARC750, i.e. ARC700 with MMU but without so-called atomic instructions (LLOCK/SCOND). To support this HW variation we need: 1) Compile all target binaries without "-matomics" or even better "-mno-atomics" so that's even future-proof (as we may decide to enable "-matomics" by default for Linux targets which is a recommented setup). 2) Configure libc such that it uses Linux-kernel-assisted implementation of atomic operation via "arc_usr_cmpxchg" syscall, see https://cgit.uclibc-ng.org/cgi/cgit/uclibc-ng.git/commit/?id=b985fa069187e4c5a7ee84213d9fbead2f219ce5 Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>
2018-05-21ARC: Disable CONFIG_ARC_HAS_ATOMICS in uClibc if building without -matomicsAlexey Brodkin1-1/+1
In case we build for ARC core which has no support of atomic ops among other things we need to configure libc to use Linux kernel helper to emulate HS atomic ops. This is done with disabling of CONFIG_ARC_HAS_ATOMICS in uClibc. Currently we __remove__ this option from .config but this makes no sense as its default state is "y" so we need to explicitly disable it instead. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com>

2018-05-21ARC: Add multilib support for Linux in GCCAlexey Brodkin1-0/+76
We never bothered to build multilibbed Linux toolchains for ARC and so we ended-up with no support of multilib for arc*-*-linux-* targets in GCC. That is now fixed in upstream by the following commit: https://gcc.gnu.org/git/?p=gcc.git;a=commit;h=0eacfbcb2bf1834294f468a2bb41fe5d5e8d3883 Once the fix mentioned above is applied on top of GCC 8.1.0 we may easily build multilibbed uClibc toolchain for ARC. Note sice Glibc port for ARC is still in review process we cannot build any Glibc toolchains for ARC with pure upstream components, for that we eiter need Glibc sources from our Github repo or apply a set of patches on top of Glibc 2.27 - we'll try to address this later though.

2018-05-16ARC: Don't mention in multilib not yet supported CPUsAlexey Brodkin1-0/+35

curl and wget are needed as a build dependency so that the auto configuration will see them and set the relevant configuration options. Otherwise, we end up with a ct-ng that can't download anything. However, curl and wget are not strict runtime dependencies, and we don't need both, so list them as Recommends: curl | wget for the binary package.
