| * | Use 'chmod a-x' instead of 'chmod -x'Alexey Neyman2018-09-266-8/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a subtle difference when executable bit is a part of the umask. And at least some versions (Debian/stretch) fail if the resulting mode would've been different if not for the umask setting. Fixes #998. Although, with such chmods/umasks it is likely that some package installation will break anyway. But I'll leave it until somebody complains. Signed-off-by: Alexey Neyman <stilor@att.net>

This error was detected by GCC's -Wmisleading-indentation when switching to build-time generation of lexer/parser. scripts/kconfig/symbol.c: In function ‘sym_check_print_recursive’: scripts/kconfig/symbol.c:1150:3: warning: this ‘if’ clause does not guard... [-Wmisleading-indentation] if (stack->sym == last_sym) ^~ scripts/kconfig/symbol.c:1153:4: note: ...this statement, but the latter is misleadingly indented as if it were guarded by the ‘if’ fprintf(stderr, "For a resolution refer to Documentation/kbuild/kconfig-language.txt\n"); ^~~~~~~ I could simply add {...} to surround the three fprintf(), but I rather chose to move the hint after the loop to make the whole message readable.

| * | ARC: Update Linux samplesAlexey Brodkin2018-05-214-12/+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>
| * | ARC: Disable CONFIG_ARC_HAS_ATOMICS in uClibc if building without -matomicsAlexey Brodkin2018-05-211-1/+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>

| * | ARC: Add multilib support for Linux in GCCAlexey Brodkin2018-05-211-0/+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.
