The common igen code was forked from the ppc long ago. The filter
module is still pretty similar in API, so we can unfork them with
a little bit of effort.
The filter.c module is still here because of the unique it_is API.
The common igen code doesn't seem to have an equiv API as this only
operates on two strings and not an actual filter object, and it's
easy enough to leave behind to unfork the rest.
|
|
The common igen code provides the same misc APIs as the ppc version,
so delete the ppc code and pull in the common one. There is one
minor difference: the ppc code has a unique dumpf function. The
common code switched to lf_printf for the same functionality, but
since that requires changes throughout the igen codebase, delay that
cleanup for now so we can merge the rest.
|
|
Switch to an ERROR macro and tweak the error signature to match the
common igen version in preparation for merging the two implementations.
|
|
We want to avoid conflicts with the common igen enums. This should
get migrated over to the common parsing logic, but for now, switch
the name to avoid redefinition.

This commit is a follow on to:
commit 182421c9d2eea8c4877d983a2124e591f0aca710

sim/ppc: fixes for arguments to printf style functions
where commit 182421c9d2ee addressed issues with printf format
arguments that were causing the compiler to give an error, this commit
addresses issues that caused the compiler to emit a warning.
This commit is mostly either changing the format string to match the
argument, or in some cases, excess, unused arguments are removed.

A random grab bag of minor fixes to enable -Werror for this port.
Cast address vars to long when the format was using %l.
Use %zu with sizeof operations.
Add const to a bunch of strings.
Trim unused variables.
Fix sizeof call to calculate target storage and not the pointer itself.

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.
