	(ICACHE_CFLAGS, SEMANTICS_CFLAGS): New variables.
	(icache.o, semantics.o): Add new ICACHE_FLAGS & SEMANTICS_FLAGS.
	(sim-fpu.o, sim-bits.o, tconfig.h): New targets.
	* configure.in: Rename INLINE_LOCALS to PSIM_INLINE_LOCALS.  Add a
	check for sim/common/sim-fpu.c.  Output sim_fpu and sim_fpu_cflags.
	* configure: Regenerate.
	* device.h (device_find_integer_array_property): Match function definition.
	* gen-icache.c (print_icache_internal_function_declaration): Rename
	INLINE_ICACHE to PSIM_INLINE_ICACHE.
	* gen-idecode.c (print_idecode_run_function_header): Rename INLINE_IDECODE
	to PSIM_INLINE_IDECODE.
	* gen-semantics.c (print_semantic_function_header): Rename
	EXTERN_SEMANTICS to PSIM_EXTERN_SEMANTICS.
	* gen-support.c (print_support_function_name): Rename INLINE_SUPPORT to
	PSIM_INLINE_SUPPORT.
	* igen.c (print_function_name): Also escape `(' and `)'.
	(gen_semantics_h): Rename EXTERN_SEMANTICS to PSIM_EXTERN_SEMANTICS.
	(gen_semantics_c): Likewise.  Also output includes for "sim-fpu.h"
	* inline.h (INLINE_SIM_ENDIAN): Renamed INLINE_PSIM_ENDIAN.
	(EXTERN_SIM_ENDIAN): Renamed EXTERN_PSIM_ENDIAN.
	(STATIC_INLINE_SIM_ENDIAN): Renamed STATIC_INLINE_PSIM_ENDIAN.
	(INLINE_LOCALS): Renamed PSIM_INLINE_LOCALS.
	(EXTERN_SUPPORT): Renamed PSIM_EXTERN_SUPPORT.
	(INLINE_SUPPORT): Renamed PSIM_INLINE_SUPPORT.
	(EXTERN_SEMANTICS): Renamed PSIM_EXTERN_SEMANTICS.
	(INLINE_SEMANTICS): Renamed PSIM_INLINE_SEMANTICS.
	(EXTERN_IDECODE): Renamed PSIM_EXTERN_IDECODE.
	(INLINE_IDECODE): Renamed PSIM_INLINE_IDECODE.
	(EXTERN_ICACHE): Renamed PSIM_EXTERN_ICACHE.
	(INLINE_ICACHE): Renamed PSIM_INLINE_ICACHE.
	* options.c (options_inline): Fix names.
	* sim-endian-n.h: Change INLINE_SIM_ENDIAN to INLINE_PSIM_ENDIAN.
	* sim-endian.h: Likewise.
	* sim-main.h: New file.
