| |
If target is bpf, there is no __loongarch__ definition, __BITS_PER_LONG defaults to 32, __NR_nanosleep is not defined:
#if defined(__ARCH_WANT_TIME32_SYSCALLS) || __BITS_PER_LONG != 32 #define __NR_nanosleep 101 __SC_3264(__NR_nanosleep, sys_nanosleep_time32, sys_nanosleep) #endif
Check __TARGET_ARCH_loongarch to include arch specified bitsperlong.h, then __BITS_PER_LONG is 64, __NR_nanosleep can also be defined to fix the following build errors:
clang -g -Werror -D__TARGET_ARCH_loongarch ... -target bpf -c progs/test_vmlinux.c ... progs/test_vmlinux.c:24:18: error: use of undeclared identifier '__NR_nanosleep' if (args->id != __NR_nanosleep) ^ progs/test_vmlinux.c:42:12: error: use of undeclared identifier '__NR_nanosleep' if (id != __NR_nanosleep) ^ progs/test_vmlinux.c:60:12: error: use of undeclared identifier '__NR_nanosleep' if (id != __NR_nanosleep) ^ 3 errors generated. make: *** [Makefile:572: tools/testing/selftests/bpf/test_vmlinux.bpf.o] Error 1 make: Leaving directory 'tools/testing/selftests/bpf'
