From 27bfcd88f7e65c81b406afa85d81b060e2ea24e3 Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Wed, 25 Jan 2017 14:32:02 +0100 Subject: score: Delete _CPU_Context_Fp_start() Since the FP area pointer is passed by reference in _CPU_Context_Initialize_fp() the optional FP area adjustment via _CPU_Context_Fp_start() is superfluous. It is also wrong with respect to memory management, e.g. pointer passed to _Workspace_Free() may be not the one returned by _Workspace_Allocate().
