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.
