However it's not safe for ilp32 on RV64, but we didn't support that yet, so I think this fix is good enough now :) Diff: --- libgloss/riscv/internal_syscall.h | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) diff --git a/libgloss/riscv/internal_syscall.h b/libgloss/riscv/internal_syscall.h index 1f1f42f5d6ca..080c8c847e04 100644 --- a/libgloss/riscv/internal_syscall.h +++ b/libgloss/riscv/internal_syscall.h @@ -63,7 +63,7 @@ __internal_syscall(long n, int argc, long _a0, long _a1, long _a2, long _a3, lon } static inline long -syscall_errno(long n, int argc, long _a0, long _a1, long _a2, long _a3, long _a4, long _a5) +_syscall_errno(long n, int argc, long _a0, long _a1, long _a2, long _a3, long _a4, long _a5) { long a0 = __internal_syscall (n, argc, _a0, _a1, _a2, _a3, _a4, _a5); @@ -73,4 +73,8 @@ syscall_errno(long n, int argc, long _a0, long _a1, long _a2, long _a3, long _a4 return a0; } +#define syscall_errno(N, ARGC, A0, A1, A2, A3, A4, A5) \ + _syscall_errno(N, ARGC, (long)A0, (long)A1, (long)A2, \ + (long)A3, (long)A4, (long)A5) + #endif
