Browse Source 
* config/ia64/ia64.c (ia64_vms_init_libfuncs): New function.
	(ia64_output_function_prologue): Only write .prologue if --with-gnu-as.
	(ia64_initialize_trampoline): If not using GAS, declare trampoline
	as global.
	* config/ia64/ia64.h (ASM_APP_ON, ASM_APP_OFF): Add vers for not GAS.
	(ASM_OUTPUT_DEBUG_LABEL): Likewise.
