Sure. You can even see VFP floating point registers with GDB 7.4.1 that comes with eCos Gnutools 4.6.3 provided that GDB server supports them. Only, for the time being eCos floating point support is not yet committed to CVS so you shall have to apply the patches from eCos' Bugzilla http://bugs.ecos.sourceware.org/show_bug.cgi?id=1001607 I will appreciate feedback.
