Hi, Willy
Here is the v5, purely include the ppc parts, with two critical fixups
for the latest gcc 13.1.0 toolchain, now, both run and run-user pass.
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.
Best regards,
Zhangjin Wu
