However this\nisn't causing any guest-visible problems, because defining the\ntarget_stat64 struct and TARGET_HAS_STRUCT_STAT64 affects these\nsyscalls:\n TARGET_NR_stat64\n TARGET_NR_lstat64\n TARGET_NR_fstat64\n TARGET_NR_fstatat64\n TARGET_NR_newfstatat\n\nFor loongarch64 the only one of those we provide is newfstatat,\nand that is actually a separate QEMU bug, because the kernel does\nnot provide that syscall for this architecture. No real guest\ncode will be using a syscall that doesn't exist in the ABI.\n\n(Some of these syscalls are present in the loongarch64 \"ABI1.0\",\nbut that ABI was never accepted in the upstream kernel, and\nQEMU does not model that ABI, only the \"ABI2.0\".)\n\nStop defining TARGET_HAS_STRUCT_STAT64 anyway, for consistency\nwith the kernel and to avoid confusion.\n\nNote:\nCommit message suggested by Peter Maydell \n\nSigned-off-by: Gyorgy Tamasi \nTested-by: Gyorgy Tamasi \nReviewed-by: Pierrick Bouvier \nReviewed-by: Peter Maydell \nSigned-off-by: Helge Deller \n---\n linux-user/syscall_defs.h | 2 +-\n 1 file changed, 1 insertion(+), 1 deletion(-)","diff":"diff --git a/linux-user/syscall_defs.h b/linux-user/syscall_defs.h\nindex 679af640c0..6967306be4 100644\n--- a/linux-user/syscall_defs.h\n+++ b/linux-user/syscall_defs.h\n@@ -2005,7 +2005,7 @@ struct target_stat {\n abi_uint __unused5;\n };\n \n-#if !defined(TARGET_RISCV64)\n+#if !defined(TARGET_RISCV64) && !defined(TARGET_LOONGARCH64)\n #define TARGET_HAS_STRUCT_STAT64\n struct target_stat64 {\n abi_ullong st_dev;\n","prefixes":["PULL","04/14"]}
