124 ; 16- and 32-bit nops can be defined as normal instructions without
125 ; any problems. nops take no operands, so nops longer than 32
126 ; bits cannot be defined as normal insns since that would result in
127 ; decodable bits beyond cgen's 32-bit boundary. As a result, we
128 ; have to use macros and other real insns to create 48- and 64-bit nops.
130 ; In addition, since the names of the nops that will be created as part
131 ; of future insn sets are not known at this time, the assembler needs a
132 ; fixed set of nop names that it can use for automatic nop insertion.
133 ; The idea is that no matter what those insns are called, we don't want
134 ; to have to change the C code in the assemblers vliw grouping validation
135 ; and nop insertion routines. We therefore have to create macros for
136 ; all nops to map the macro names which are known to the assembler to the
137 ; names of the real nop insns.
