* s-osinte-tru64.adb: Mark Asm statements Volatile to prevent warnings (seems a reasonable change anyway) Fixes new warnings * s-mastop-irix.adb: Add Volatile to Asm statements Suppresses warning, and seems appropriate in any case * s-osinte-vms.adb: Add Volatile to Asm statement * s-vaflop-vms-alpha.adb: Add Volatile to Asm statements * exp_code.ads, exp_code.adb (Asm_Input_Value): Note that Error can be returned. Add call to Check_Code_Statement git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@118329 138bc75d-0d04-0410-961f-82ee72b054a4
