target/ppc: code motion from translate_init.c.inc to gdbstub.c

Commit Message

Bruno Larsen (billionai) April 12, 2021, 7:04 p.m. UTC

As suggested by Fabiano Rosas, all the code related to gdb has been moved
from translate_init.c.inc file to the gdbstub.c file, where it makes more
sense

This comment has served its purpose for the RFC I think. You can drop it.

I don't think "cpu" adds much here. ppc_gdb_init gets the meaning across
just fine.

We still need to figure out where to move the vscr helpers so that both
TCG and !TCG code can see them. But we cannot build without TCG
currently anyway so I guess it's ok to leave the ifdef.

This one is not being used.

Where is the removal of this from translate_init.inc.c? You must have
left it unstaged in your tree.

Same here.

All the code and git related feedback as been done, with the exception of

Actually, since we're moving the helpers away, I think it's better to remove the ifdefs...
The helper-proto.h is here only for the vscr, so it's going away before we support the !tcg build anyway. Thoughts?

This function was actually created by me, wasn't in the translate_init.c.inc. Since we're moving gdb fuinctions to gdbstub.c, I thought it made sense to hide the logic behind how to register coprocessors correctly as well. that's why there is no removal of this function on the diff. Should I move it back to ppc_cpu_realize or is this a good plan?

Sure, that's reasonable.

Since we're moving gdb fuinctions to gdbstub.c, I thought it made sense to hide the logic behind how to register coprocessors correctly as well. that's why there is no removal of this function on the diff. Should I move it back to ppc_cpu_realize or is this a good plan?

Right, but you created the function by refactoring the existing code in
translate_init.c.inc so the diff still needs to contain the removal of
the gdb_register_coprocessor calls from that file.
