Subject: 	* elf32-spu.c (mark_functions_via_relocs): Don't assume that
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=911f096e1a0b04d82d059a42e459b15503c285ce;p=binutils-gdb.git

	* elf32-spu.c (mark_functions_via_relocs): Don't assume that
	the "->start" pointer reaches to function origin, so that we
	can handle functions split over more than two sections.
	(build_call_tree): Likewise.
	(pasted_function): Don't attempt to set fun->start back to the
	function origin, just go back one section.
