* musl: Do not pass -frounding-math for nowKhem Raj2020-02-211-0/+7
| | | | | | clang/master hangs (can you believe) while compiling musl on armv7ve Signed-off-by: Khem Raj <raj.khem@gmail.com>
* packagegroup: be lenient about CLANGSDK settingRoss Burton2019-12-022-2/+2
| | | | | | | | | | | As CLANGSDK defaults to '1', users who have not read the README may think that setting it to '0' would disable adding Clang to the SDK. Little do they know that you need to *unset* the value for this to work (as bool('0') -> True). Change the logic to use bb.utils.contains(), so that '0' is not true.

* clang: Add variable CLANGSDK to control including clang in SDKKhem Raj2019-09-253-14/+4
| | | | | | | | | | | | | | CLANGSDK ?= "1" is default which means clang will be included into SDK if one is using clang only for full build and dont intend to distribute it as cross compiler SDK then set CLANGSDK = "" in local.conf or in another config metadata file Signed-off-by: Khem Raj <raj.khem@gmail.com>
* busybox: Update non-const patch to remaining patternsKhem Raj2019-09-112-7/+55
| | | | | | | | | | | This was noticed when /bin/ash crashed that there are more instances of this optimization which causes same kind of failures in few other applets As a side benefit busybox compiled with clang works totally fine on riscv64 now Signed-off-by: Khem Raj <raj.khem@gmail.com>
* musl: Do not use clang for musl package on ppc64Khem Raj2019-09-021-0/+1
| | | | | | | Fails to build with builtins which are only in compiler-rt but compiler-rt needs C library to build. Catch-22 Signed-off-by: Khem Raj <raj.khem@gmail.com>
* musl: Use gcc for riscv64 for nowKhem Raj2019-08-141-0/+1
| | | | | | | system boot but not all the way to command prompt so we need to debug it eventually Signed-off-by: Khem Raj <raj.khem@gmail.com>
* busybox: Use gcc for riscv64 for nowKhem Raj2019-08-121-0/+1
| | | | | | It crashes when compiled with clang Signed-off-by: Khem Raj <raj.khem@gmail.com>

* musl: Use gcc to compile alwaysKhem Raj2019-07-111-0/+1
| | | | | | | | | clang needs built-ins from compiler-rt to build musl and compiler-rt needs a full toolchain to build which means we have a catch-22 on x32 with clang/musl, for now use gcc to compile musl to break the jinx Signed-off-by: Khem Raj <raj.khem@gmail.com>
* busybox: Use gcc to compile on x86Khem Raj2019-03-031-0/+1
| | | | | | | i386 inline assembly runs out of registers on clang so for now let gcc be used Signed-off-by: Khem Raj <raj.khem@gmail.com>
* compiler-rt: Define AR, NM and RANLIB to point to llvm wrappersKhem Raj2019-02-141-0/+1
| | | | | | helps with LTO enabled cross builds Signed-off-by: Khem Raj <raj.khem@gmail.com>
* clang: Enable a cross version of clang-tidyKhem Raj2019-01-311-0/+1
| | | | | | define CLANG_TIDY_EXE which is used by some build systems e.g. cmake Signed-off-by: Khem Raj <raj.khem@gmail.com>

* clang,nativesdk-packagegroup-sdk-host: Recognise risc-vKhem Raj2018-12-271-1/+0
| | | | | | | This helps build SDKs for risc-v when meta-clang is in layer mix even though clang for risc-v may not fully work yet Signed-off-by: Khem Raj <raj.khem@gmail.com>
* busybox: Do not build in thumb2 mode.Khem Raj2018-12-091-0/+1
| | | | | | | There is a bug in busybox which is found by clang, we need to fix busybox but until them just dont use thumb2 ISA for busybox Signed-off-by: Khem Raj <raj.khem@gmail.com>
* systemd: Drop systemd bbappendKhem Raj2018-12-091-4/+0
| | | | | | Not needed after meson migration Signed-off-by: Khem Raj <raj.khem@gmail.com>
* packagegroup-core-standalone-sdk-target: Make clang runtime as RRECOMMENDSKhem Raj2018-09-091-1/+1
| | | | | | | As suggested in Issue #23 this will make sure we can override it with BAD_RECOMMENDATIONS Signed-off-by: Khem Raj <raj.khem@gmail.com>

* libcxx: Merge libcxxabi needs into libcxxKhem Raj2017-07-311-1/+0
| | | | | | | | | This is preferred way of building libc++ and it also means we do not need musl specific tweaks since top level build from llvm already know musl and make right choices Signed-off-by: Khem Raj <raj.khem@gmail.com>

* ncurses: fix build errors in some clang configurationsDaniel McGregor2017-02-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | ncurses' configure script strips the arguments from $CC when checking if -c and -o can be used together. Clang then doesn't have a default sysroot argument to use, so it checks the host for the existence of certain feature headers in libc. These checks fail, and it assumes that clang can't handle -o and -c together. Example config.log snippet: configure:2524: checking whether arm-poky-linux-gnueabi-clang understands -c and -o together configure:2540: arm-poky-linux-gnueabi-clang -c conftest.c -o conftest2.o >&5 In file included from conftest.c:1: In file included from /usr/include/stdio.h:27: In file included from /usr/include/features.h:399: /usr/include/gnu/stubs.h:7:11: fatal error: 'gnu/stubs-32.h' file not found # include <gnu/stubs-32.h> ^ 1 error generated. configure:2543: $? = 1 configure:2562: result: no Signed-off-by: Daniel McGregor <daniel.mcgregor@vecima.com>

* Remove -mmusl and -muclibcKhem Raj2016-04-011-0/+3
| | | | | | | | | | | | | | | | | | | | | | | These options were introduced in OE-Core to support multi libc SDKs and added with Author: Richard Purdie <richard.purdie@linuxfoundation.org> Date: Sat Jul 25 14:48:21 2015 +0100 toolchain-scripts: For non-glibc, pass compiler options to ensure the correct libc selection gcc-cross-canadian-<arch> is only built once. It needs to target all the different libcs, not just the currently selected one. This change ensures that if another libc is used, the compiler correctly selects the right one. [YOCTO #8025] (From OE-Core rev: da2e92e256054b137a1646fdad1fe1a47ba3215a) Clang however acts based on crosscompiler name and does not have option to controlled multi libc scene Signed-off-by: Khem Raj <raj.khem@gmail.com>
