--- Comment #4 from Alan Modra <amodra at gmail dot com> --- You could do that, but smaller stack frames is one of the nice features of the ELFv2 ABI! What I called the "quick and dirty" fix seems to be the way to go, as the scheme I had in mind to avoid a new INCOMING_REG_PARM_STACK_SPACE target macro only works with very old versions of gcc..
