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.
