Rewrite SPU overlay handling code. Put overlay calls stubs in the

[binutils.git] / bfd / ChangeLog

2008-01-28  Alan Modra  <[email protected]>

	Rewrite SPU overlay handling code.  Put overlay calls stubs in the
	overlays where possible.  Use a faster call stub, or optionally at
	compile time, a more compact stub.  Double size of _ovly_buf_table
	so that low bit of _ovly_table.buf can be used as a "present" bit.
	Reserve an extra _ovly_table entry for index zero.

	add new ones.
