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.

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.

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 Commit: ab3c204aee88f08481f1f63825d0e94b082ef84e https://github.com/crosstool-ng/crosstool-ng/commit/ab3c204aee88f08481f1f63825d0e94b082ef84e Author: Alexey Neyman Date: 2018-05-21 (Mon, 21 May 2018) Changed paths: A packages/gcc/8.1.0/0019-ARC-Add-multilib-support-for-linux-targets.patch M samples/arc-arc700-linux-uclibc/crosstool.config M samples/arc-arc700-linux-uclibc/reported.by R samples/arc-archs-linux-uclibc/crosstool.config R samples/arc-archs-linux-uclibc/reported.by A samples/arc-multilib-linux-uclibc/crosstool.config A samples/arc-multilib-linux-uclibc/reported.by M scripts/build/arch/arc.sh Log Message: ----------- Merge pull request #970 from abrodkin/topic-uclibc-multilib Add support and sample for uclibc multilib toolchain for ARC Compare: https://github.com/crosstool-ng/crosstool-ng/compare/ea53be7529f4...ab3c204aee88 **NOTE:** This service been marked for deprecation: https://developer.github.com/changes/2018-04-25-github-services-deprecation/ Functionality will be removed from GitHub.com on January 31st, 2019.
