UltraSPARC User’s Manual
most significant bit of the mask (not the entire register) corresponds to the most
significant part of the rs1 register. The data is stored in little-endian form in mem-
ory if the ASI name has a “_LITTLE” suffix; otherwise, it is big-endian.
Note: If the byte ordering is little-endian, the byte enables generated by this
instruction are swapped with respect to big-endian.
Traps:
fp_disabled
mem_address_not_aligned
data_access_exception
PA_watchpoint
VA_watchpoint
illegal_instruction
(when
i
= 1, no immediate mode is supported. This is not checked if
there is a
data_access_exception
for a non-STDFA opcode).
