Similar to PR70098, which is about integers in floating point registers, we can have the completely analogous problem with vector registers as well now that we allow integers in vector registers. So, this patch solves it in the same way. This only works for targets with direct move. To recap: register allocation can decide to put an integer mode value in a floating point or vector register. If that register is used in a bd*z instruction, which is a jump instruction, reload can not do an output reload on it (it does not do output reloads on any jump insns), so the float or vector register will remain, and we have to allow it here or recog will ICE. Later on we will split this to valid instructions, including a move from that fp/vec register to an int register; it is this move that will still fail (PR70098) if we do not have direct move enabled.

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
