2020-11-17binutils: reproducibility: reuse debug-prefix-map for stabsDenys Zagorui
powerpc 32bit Linux Kernel widely uses .stabs pseudo-op to produce debugging information in stabs format. Faced an issue that during Linux Kernel build with Yocto build system for 32bit powerpc platform resulting vmlinux contains absolute path in .stabstr section that cannot be remapped with -fdebug-prefix-map option. Yocto uses scripts/mkmakefile Linux Kernel build approach that allows to store all generated files outside of kernel source tree. With this approach each compilier invocation is performed with an absolute path to a file that will be compiled and this absolute path is recorded in init stab. There is no way to remap this path. Reuse remap_debug_filename api to make -fdebug-prefix-map flag aplicable for init stab.

2020-04-03nativesdk-binutils: correct path to ld.so.confJeremy Puhlman
The alternative ld.so patch is set up so the linker will search the nativesdk sysroot before searching the host filesystem. However the patch concatenates <sysroot>/etc and /etc/ld.so.conf leading to a path that does not exist: 3061991 openat(AT_FDCWD, "/buildtools/sysroots/x86_64-pokysdk-linux/etc/etc/ld.so.conf", O_RDONLY) = -1 ENOENT (No such file or directory) In native-nspr, the build uses -lpthread, which triggers a search for librt, but because of the above it drags in the system librt leading to errors as follows: /buildtools/sysroots/x86_64-pokysdk-linux/usr/lib/gcc/x86_64-pokysdk-linux/ 9.3.0/../../../../x86_64-pokysdk-linux/bin/ld: /lib64/librt.so.1: undefined reference to `__clock_getcpuclockid@GLIBC_PRIVATE' update concatenation to correctly construct the path to the nativesdk ld.so.conf [YOCTO #13853] Signed-off-by: Jeremy Puhlman <jpuhlman@mvista.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2020-04-01binutils: Do not build gold linker on mips/glibcKhem Raj
Using gnu_hash style is unsupported on gold for now therefore disable building gold on mips/glibc Certain applications poke for presence of gold linker and silently use it (webkit), therefore its best to disable building it Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2020-03-30binutils: Pregenerate autoconf filesKhem Raj
libtool patch will result in configure file regeneration, instead of doing that at build time, do it in patch itself, this avoids running autoconf before configure step. Since binutils needs specific version of autoconf ( which is 2.69 ) this will break on systems using newer or older verisons of autoconf in current state.

This is not a good idea and we have tests to detect it which failed: oe-selftest -r sstatetests.SStateTests.test_sstate_32_64_same_hash binutils-native already enables all targets so we can avoid issues by not setting this option in the native case.

2020-02-14binutils: Bail out if gold is used on 32/64 bit RISC-VKhem Raj

2020-01-22binutils: Fix relocation of ld.so.conf in nativesdk buildsRichard Purdie
We need binutils to look at our ld.so.conf file within the SDK to ensure we search the SDK's libdirs as well as those from the host system. There add a patch which passes in the directory to the code using a define, then add it to a section we relocate in a similar way to the way we relocate the gcc internal paths. This ensures that ld works correctly in our buildtools tarball. Standard sysroot relocation doesn't work since we're not in a sysroot, we want to use both the host system and SDK libs.

2019-09-06binutils-cross-testsuite: Create recipe for test suite executionNathan Rossi
Create the do_check task in a new recipe 'binutils-cross-testsuite'. This recipe is built within a target recipe (not -cross) to ensure correct testing against target specific libraries/etc. The do_check task is used to execute the binutils test suite for the cross target binutils. By default this executes tests for binutils, gas and ld. This can however be changed by setting CHECK_TARGETS to the desired test suite target (e.g. 'gas'). The binutils test suites do not require any target execution, as such the check task can be run without QEMU or a target device. However since the binutils tests do rely on a C compiler there is dependence on both gcc and libc in order to run the tests.

2018-10-09binutils: fix symlinksAchille Fouilleul
For nativesdk, symlinks created by do_install contain ${SDKPATHNATIVE}. This is a problem with SDKs that include nativesdk-binutils and nativesdk-gcc. When extracting such an SDK dangling symlinks are created, because relocate_sdk.py does not adjust symlinks. As a result gcc ends up calling the host binutils. Use the os.path.relpath function to obtain shorter relative paths, which do not contain ${SDKPATHNATIVE}.
