2021-06-12sim: rx: replace cycle-stats with common profile settingsMike Frysinger1-1/+1
The common sim-profile option controls whether to keep track of runtime execution (like cycle count), so switch the rx-specific cycle-stats option over to that.
2021-05-16sim: switch config.h usage to defs.hMike Frysinger1-1/+3
The defs.h header will take care of including the various config.h headers. For now, it's just config.h, but we'll add more when we integrate gnulib in. This header should be used instead of config.h, and should be the first include in every .c file. We won't rely on the old behavior where we expected files to include the port's sim-main.h which then includes the common sim-basics.h which then includes config.h. We have a ton of code that includes things before sim-main.h, and it sometimes needs to be that way. Creating a dedicated header avoids the ordering mess and implicit inclusion that shows up otherwise.
2021-02-08sim/rx: avoid pointer arithmetic on void * pointersAndrew Burgess1-4/+8
Pointer arithmetic on void * pointers results in a GCC warning. Avoid the warning by casting the pointer to its actual type earlier in the function. sim/rx/ChangeLog: * mem.c (mem_put_blk): Rename parameter, add cast from parameter type to local type. Remove cast later in the function. (mem_get_blk): Likewise. * mem.h (mem_put_blk): Rename parameter to match definition. (mem_get_blk): Likewise.
2021-02-08sim/rx: mark some functions as staticAndrew Burgess1-1/+1
Some functions that should be marked static. sim/rx/ChangeLog: * fpu.c (check_exceptions): Make static. * gdb-if.c (handle_step): Likewise. * mem.c (mem_put_byte): Likewise.
2021-02-08sim/rx: fill in missing 'void' for empty argument listsAndrew Burgess1-2/+2
Ensure we have 'void' inside empty argument lists. This was causing several warnings for the rx simulator. sim/rx/ChangeLog: * cpu.h (trace_register_changes): Add void parameter type. * err.c (ee_overrides): Likewise. * mem.c (mem_usage_stats): Likewise. (e): Likewise. * reg.c (stack_heap_stats): Likewise. * rx.c (pop): Likewise. (poppc): Likewise. (decode_opcode): Likewise. * syscalls.c (arg): Likewise.
2021-01-01Update copyright year range in all GDB filesJoel Brobecker1-1/+1
This commits the result of running gdb/copyright.py as per our Start of New Year procedure... gdb/ChangeLog Update copyright year range in copyright header of all GDB files.

gdb/ChangeLog: Update copyright year range in all GDB files.
2019-01-01Update copyright year range in all GDB files.Joel Brobecker1-1/+1
This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.

2017-01-01update copyright year range in GDB filesJoel Brobecker1-1/+1
This applies the second part of GDB's End of Year Procedure, which updates the copyright year range in all of GDB's files. gdb/ChangeLog: Update copyright year range in all GDB files.

gdb/ChangeLog: Update year range in copyright notice of all files.
2014-01-01Update Copyright year range in all files maintained by GDB.Joel Brobecker1-1/+1
2013-01-01Update years in copyright notice for the GDB files.Joel Brobecker1-1/+1
Two modifications: 1. The addition of 2013 to the copyright year range for every file; 2. The use of a single year range, instead of potentially multiple year ranges, as approved by the FSF.
