+Subject: [PATCH] sim/ppc: Fix linker error with -fno-common
+
+GCC 10 enables -fno-common by default. This resulted in a multiple
+definition linker error since global variables were declared and defined
+in a header file:
+
+ ld: ld-insn.o:sim/ppc/ld-insn.h:221: multiple definition of
+ `max_model_fields_len'; igen.o:sim/ppc/ld-insn.h:221: first defined here
+
+sim/ppc
+
+ * ld-insn.h (last_model, last_model_data, last_model_function,
+ last_model_internal, last_model_macro, last_model_static):
+ Delete.
+ (max_model_fields_len, model_data, model_functions,
+ model_internal, model_macros, model_static, models): Declare, but do not
+ define.
+ * ld-insn.c (last_model, last_model_data, last_model_function,
+ last_model_internal, last_model_macro, last_model_static,
+ max_model_fields_len, model_data, model_functions,
+ model_internal, model_macros, model_static, models): Define.
+
+(cherry picked from commit ad8464f799a4c96c7ab8bdfec3f95846cf54f9b0)
+---
+
+This patch is a trivial backport from the upstream commit mentioned above.
+Only the ChangeLog had to be adapted.
