Subject: usefulness of NO_ARGS_ARRAY
Date: Thu, 15 Apr 2010 18:13:49 -0400 [thread overview]
Message-ID: <yxq8w8ogy8y.fsf@fencepost.gnu.org> (raw)
NO_ARGS_ARRAY is currently only used on 32bit x86 non-MS Windows machines.
It's doubtful that the few instructions saved make any difference on
modern machines...
NO_ARGS_ARRAY assumes that function arguments are passed on the stack,
but that is not true when using the -mregparam option, or when the
compiler decides to change the calling convention (like gcc-4.5 can
when using -flto).
Do we still want to keep NO_ARGS_ARRAY?
