The general syntax is the following: - -@smallexample -%modifier(symbol) -@end smallexample - -@table @code -@cindex symbol modifiers - -@item %dsp8 -@itemx %dsp16 - -These modifiers override the assembler's assumptions about how big a -symbol's address is. Normally, when it sees an operand like -@samp{sym[a0]} it assumes @samp{sym} may require the widest -displacement field (16 bits for @samp{-m16c}, 24 bits for -@samp{-m32c}). These modifiers tell it to assume the address will fit -in an 8 or 16 bit (respectively) unsigned displacement. Note that, of -course, if it doesn't actually fit you will get linker errors. Example: - -@smallexample -mov.w %dsp8(sym)[a0],r1 -mov.b #0,%dsp8(sym)[a0] -@end smallexample - -@item %hi8 - -This modifier allows you to load bits 16 through 23 of a 24 bit -address into an 8 bit register. This is useful with, for example, the -M16C @samp{smovf} instruction, which expects a 20 bit address in -@samp{r1h} and @samp{a0}. Example: - -@smallexample -mov.b #%hi8(sym),r1h -mov.w #%lo16(sym),a0 -smovf.b -@end smallexample - -@item %lo16 - -Likewise, this modifier allows you to load bits 0 through 15 of a 24 -bit address into a 16 bit register. - -@item %hi16 - -This modifier allows you to load bits 16 through 31 of a 32 bit -address into a 16 bit register. While the M32C family only has 24 -bits of address space, it does support addresses in pairs of 16 bit -registers (like @samp{a1a0} for the @samp{lde} instruction). This -modifier is for loading the upper half in such cases.
