newlib/include/elf/sh.h
Joern Rennecke f9ef90e3ab 2003-03-03 Andrew Stubbs <andrew.stubbs@superh.com> 
opcodes:
	* sh-dis.c (print_insn_sh): Don't disassemble fp instructions in
	nofpu mode.  Add BFD type bfd_mach_sh4_nommu_nofpu.
	* sh-opc.h: Add sh4_nommu_nofpu architecture and adjust instructions
	accordingly.
bfd:
	* archures.c: Add bfd_mach_sh4_nommu_nofpu.
	* cpu-sh.c: Ditto.
	* elf32-sh.c: Ditto.
	* bfd-in2.h: Regenerate.
include/elf:
	* sh.h: Add EF_SH4_NOMMU_NOFPU.
gas:
	* config/tc-sh.c (md_parse_option): Add -isa=sh4-nofpu and
	-isa=sh4-nommu-nofpu options. Adjust help messages accordingly.
	(sh_elf_final_processing): Output BFD type sh4_nofpu if that is
	the most general type or the user specifically requested it.
	(md_assemble): Add a new error message for when an instruction
	is understood, but is not allowed due to an -isa option.
