2002-02-19  Philip Blundell  <pb@nexus.co.uk>

	PR 5185
	* config/arm/arm.h (THUMB_LEGITIMATE_CONSTANT_P): Accept anything
	if generating PIC.

	PR 5054
	* config/arm/arm.md (call_insn) [TARGET_THUMB]: Use
	arm_is_longcall_p rather than inspecting call-type cookie
	directly.
	(call_value_insn) [TARGET_THUMB]: Likewise.
