Subject: [PATCH] Add rudimentary FR-V support.
Date: Fri, 14 Nov 2003 21:24:00 -0000	[thread overview]
Message-ID: <1031114212437.ZM11691@localhost.localdomain> (raw)

I've just committed the patch below.

	* config.in (FRV_LINUX_TARGET): Add.
	* configure.in (sys/user.h): Don't check for this header; it's
	not used.
	(frv*linux*): Add rudimentary support for FR-V Linux.
	* linux-target.c (PEEKUSER_POKEUSER_REGINFO, NUM_REGS, PC_REGNUM)
	(sign_extend, greg_offset_and_size, fpreg_offset_and_size)
	(noreg_offset_and_size, reginfo) [FRV_LINUX_TARGET]: Define.
	* configure, Makefile.in: Regenerate.
