libcxx: Disable libunwind on all mips

2017-09-19T04:01:06+00:00

llvm libunwind is still not ported to mips Signed-off-by: Khem Raj

clang.bbclass: Prepend instead of appending to overrides

2017-09-10T08:40:49+00:00

Right now it becomes highest priority override which we dont want Signed-off-by: Khem Raj

classes: Do not replace armv7ve with armv7a anymore

2017-08-29T15:51:10+00:00

clang-5.0 supports the option now Signed-off-by: Khem Raj

clang: fix nativesdk build

2017-08-23T16:10:29+00:00

I could not manage to build nativesdk-clang, I encountered errors as follows: (trimmed for purpose) | ../gcc/x86_64-pokysdk-linux/6.3.0/ld:: | cannot find crt1.o: No such file or directory | cannot find crtbegin.o: No such file or directory | cannot find -lgcc | cannot find -lgcc_s After some investigation, I found it's caused by the llvm native tools could not compile with crosssdk toolchains. (special linking flags are needed) So we introduce a cmake-native class with a task to generate a native toolchain file, it will be used to build llvm native tools by passed with CROSS_TOOLCHAIN_FLAGS_NATIVE.

clang: Switch c++ default to gnu++14 standard

2017-08-12T20:13:53+00:00

Using cmdline options -std doesnt always work e.g. boost where it uses c++ driver (clang++) to invoke compilation but then passes '-x c' to choose the language for compilation Which ends in errors like below error: invalid argument '-std=c++14' not allowed with 'C' Therefore change the defaults in driver itself to use gnu++14 which is default with g++ from gcc7+ too.

clang++: Default to c++14 std

2017-08-12T17:27:23+00:00

latest gcc7 also defaults to c++14, some packages have started to use c++11 and newer features without specifying -std option and rightly so now that gcc defaults are c++14, applications can safely assume c++14 as default Signed-off-by: Khem Raj

llvm-libunwind: Delete

2017-07-31T16:20:22+00:00

build llvm libunwind along with libcxx Signed-off-by: Khem Raj

clang: Default to PIE when GCCPIE is set

2017-07-29T17:31:38+00:00

This matches with OE-Core expectations and we do not need to inject PIE flags manually via SECURITY_CFLAGS which does not always work Signed-off-by: Khem Raj

clang.bbclass: Add -pie -fPIE to SECURITY_PIE_CFLAGS explicitly

2017-07-21T14:50:40+00:00

gcc in core now is configured with these options but clang does not have a configuration level knob so we still need to pass it old way Signed-off-by: Khem Raj
