riscv: add asm/unistd.h UAPI header
|
|
|
|
|
|
|
|
|
|
Marcin Juszkiewicz reported issues while generating syscall table for riscv
|
|
|
|
|
using 4.20-rc1. The patch refactors our unistd.h files to match some other
|
|
|
|
|
architectures.
|
|
|
|
|
|
|
|
|
|
- Add asm/unistd.h UAPI header, which has __ARCH_WANT_NEW_STAT only for 64-bit
|
|
|
|
|
- Remove asm/syscalls.h UAPI header and merge to asm/unistd.h
|
|
|
|
|
- Adjust kernel asm/unistd.h
|
|
|
|
|
|
|
|
|
|
So now asm/unistd.h UAPI header should show all syscalls for riscv.
|
|
|
|
|
|
|
|
|
|
<asm/syscalls.h> may be restored by

UAPI header asm/syscalls.h was merged into UAPI asm/unistd.h header,
|
|
|
|
|
which did resolve issue with missing syscalls macros resulting in
|
|
|
|
|
glibc (2.28) build failure. It also broke glibc in a different way:
|
|
|
|
|
asm/syscalls.h is being used by glibc. I noticed this while doing
|
|
|
|
|
Fedora 30/Rawhide mass rebuild.
|
|
|
|
|
|
|
|
|
|
The patch returns asm/syscalls.h header and incl. it into asm/unistd.h.
|
|
|
|
|
I plan to send a patch to glibc to use asm/unistd.h instead of
|
|
|
|
|
asm/syscalls.h
|
|
|
|
|
|
|
|
|
|
In the meantime, we use __has_include__, which was added to GCC 5, to
|
|
|
|
|
check if <asm/syscalls.h> exists before including it. Tested with
|
|
|
|
|
build-many-glibcs.py for riscv against kernel 4.19.12 and 4.20-rc7.

* sysdeps/unix/sysv/linux/riscv/flush-icache.c: Check if
|
|
|
|
|
<asm/syscalls.h> exists with __has_include__ before including it.
