Here is the run-user test report: // with local toolchains $ for arch in ppc ppc64 ppc64le; do make run-user XARCH=$arch | grep "status: "; done 165 test(s): 157 passed, 8 skipped, 0 failed => status: warning 165 test(s): 157 passed, 8 skipped, 0 failed => status: warning 165 test(s): 157 passed, 8 skipped, 0 failed => status: warning // with latest toolchains $ for arch in ppc ppc64 ppc64le; do make run-user XARCH=$arch CC=/path/to/gcc-13.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc | grep status; file nolibc-test; done 165 test(s): 157 passed, 8 skipped, 0 failed => status: warning nolibc-test: ELF 32-bit MSB executable, PowerPC or cisco 4500, version 1 (SYSV), statically linked, stripped 165 test(s): 157 passed, 8 skipped, 0 failed => status: warning nolibc-test: ELF 64-bit MSB executable, 64-bit PowerPC or cisco 7500, version 1 (SYSV), statically linked, stripped 165 test(s): 157 passed, 8 skipped, 0 failed => status: warning nolibc-test: ELF 64-bit LSB executable, 64-bit PowerPC or cisco 7500, version 1 (SYSV), statically linked, stripped Since the missing serial console enabling patch [1] for ppc32 has already gotten a Reviewed-by line from the ppc maintainer, now, the ppc defconfig aligns with the others', and it is able to simply move the nolibc-test-config related stuff to the next tinyconfig series. Based on v4 [2], beside removing several nolibc-test-config related patches, two bugs with the latest gcc 13.1.0 have been fixed. Changes from v4 --> v5: * tools/nolibc: add support for powerpc64 selftests/nolibc: add XARCH and ARCH mapping support selftests/nolibc: add test support for ppc64 selftests/nolibc: allow customize CROSS_COMPILE by architecture selftests/nolibc: customize CROSS_COMPILE for 32/64-bit powerpc Almost the same as v4. * tools/nolibc: add support for powerpc For 32-bit PowerPC, with newer gcc compilers (e.g. gcc 13.1.0), "omit-frame-pointer" fails with __attribute__((no_stack_protector)) but works with __attribute__((__optimize__("-fno-stack-protector"))) Using the later for ppc32 to workaround the issue. * selftests/nolibc: add test support for ppc Add default CFLAGS for ppc to allow build with the latest powerpc64-linux-gcc toolchain from https://mirrors.edge.kernel.org/pub/tools/crosstool/ * selftests/nolibc: add test support for ppc64le Align with kernel, prefer elfv2 ABI to elfv1 ABI when the toolchain support, otherwise, ABI mismatched binary will not run.
