Subject: [PATCH v2 00/12] tools/nolibc: shrink arch support
Date: Sat, 8 Jul 2023 23:25:37 +0800 [thread overview]
Message-ID: <cover.1688828139.git.falcon@tinylab.org> (raw)
Hi, Willy
This is v2 of the "tools/nolibc: shrink arch support" [1].
This v2 has no core code logic change, but applies some suggestions from
Willy and Thomas, one is using post-whitespaces instead of post-tab,
another is restructuring the arch support directory and files [2].
Like musl, this v2 creates <ARCH> directory for every arch and splits
the old arch-<ARCH>.h to <ARCH>/{crt.h, sys.h} and at the same time,
splits the old arch.h to crt_arch.h and sys_arch.h. at last, only need
to include crt_arch.h in crt.h and sys_arch.h in sys.h respectively, and
no longer need to include arch.h in the other common headers:
crt.h <-- crt_arch.h <-- <ARCH>/crt.h
sys.h <-- sys_arch.h <-- <ARCH>/sys.h
It is based on the 20230705-nolibc-series2 branch of nolibc repo [3]. It
should be applied after the v6 __sysret helper series [4] and the v4
min config support series [5].
Here is the test report for all of the supported architectures:
arch/board | result
------------|------------
arm/vexpress-a9 | 142 test(s) passed, 1 skipped, 0 failed.
arm/virt | 142 test(s) passed, 1 skipped, 0 failed.
aarch64/virt | 142 test(s) passed, 1 skipped, 0 failed.
ppc/g3beige | not supported
ppc/ppce500 | not supported
i386/pc | 142 test(s) passed, 1 skipped, 0 failed.
x86_64/pc | 142 test(s) passed, 1 skipped, 0 failed.
mipsel/malta | 142 test(s) passed, 1 skipped, 0 failed.
loongarch64/virt | 142 test(s) passed, 1 skipped, 0 failed.
riscv64/virt | 142 test(s) passed, 1 skipped, 0 failed.
riscv32/virt | 0 test(s) passed, 0 skipped, 0 failed.
s390x/s390-ccw-virtio | 142 test(s) passed, 1 skipped, 0 failed.
Changes from v1 --> v2:
* tools/nolibc: rename arch-<ARCH>.h to <ARCH>/arch.h
tools/nolibc: split arch.h to crt.h and sys.h
Restruct the arch support directory and files.
Fix up the errors reported by scripts/checkpatch.pl.
* tools/nolibc: sys.h: remove the old sys_stat support
Rebase on the new arch support directory and files.
* tools/nolibc: crt.h: add _start_c
Move #include "compiler.h" in the common crt.h too.
* tools/nolibc: arm/crt.h: shrink _start with _start_c
tools/nolibc: aarch64/crt.h: shrink _start with _start_c
tools/nolibc: i386/crt.h: shrink _start with _start_c
tools/nolibc: x86_64/crt.h: shrink _start with _start_c
tools/nolibc: mips/crt.h: shrink _start with _start_c
tools/nolibc: loongarch/crt.h: shrink _start with _start_c
tools/nolibc: riscv/crt.h: shrink _start with _start_c
tools/nolibc: s390/crt.h: shrink _start with _start_c
Rebase on the new arch support directory and files.
Use post-whitespaces instead of post-tab.
Best regards,
Zhangjin
