SYNTAX
FUNCTION
DESCRIPTION
arguments. (Note: pseudo operations cannot be used in assembly files.)
address formed from the sum rsrc1 + d. The value of the opcode modifier d must be in the range -64 and 63 inclusive.
This operation does not depend on the bytesex bit in the PCSW since only a single byte is stored.
defined only for 32-bit loads and stores.
modification of the addressed memory location (and the modification of cache if the location is cacheable). If the LSB
of rguard is 1, the store takes effect. If the LSB of rguard is 0, st8d has no side effects whatever; in particular, the LRU
and other status bits in the data cache are not affected.
