+Subject: [PATCH] LoongArch: Modify inconsistent behavior of ld with
+ --unresolved-symbols=ignore-all
+
+Remove duplicated check when producing executable files that reference external symbols
+defined in other files. RELOC_FOR_GLOBAL_SYMBOL will check it.
+
+Testcase is:
+resolv.c:
+int main(int argc, char *argv[]) {
+    return argc;
+}
+
+t.c:
+
+extern const struct my_struct ms1;
+static const struct my_struct *ms = &ms1;
+
+t.h:
+typedef struct my_struct {
+    char *str;
+    int i;
+} my_struct;
+
+Compiling and linking command with:
+gcc t.c -c ; gcc resolv.c -c
+gcc resolv.o t.o -o resolv -Wl,--unresolved-symbols=ignore-all
+
+Got error as:
+~/install/usr/bin/ld: t.o:(.data.rel+0x0): undefined reference to `ms1'
+collect2: error: ld returned 1 exit status
