SH64 operands consist of either a register or immediate value. The immediate value can be a constant or label reference (or portion of a label reference), as in this example:
movi 4,r2
pt function, tr4
movi (function >> 16) & 65535,r0
shori function & 65535, r0
ld.l r0,4,r0
Instruction label references can reference labels in either SHmedia or
SHcompact. To differentiate between the two, labels in SHmedia sections
will always have the least significant bit set (i.e. they will be odd),
which SHcompact labels will have the least significant bit reset
(i.e. they will be even). If you need to reference the actual address
of a label, you can use the datalabel modifier, as in this
example:
.long function
.long datalabel function
In that example, the first longword may or may not have the least significant bit set depending on whether the label is an SHmedia label or an SHcompact label. The second longword will be the actual address of the label, regardless of what type of label it is.
