7.2.4 RLIST
The RLIST (register list) directive gives a name to a set of general-purpose registers.
Syntax
name RLIST {list-of-registers}
where:
name is the name to be given to the set of registers. name cannot be the same as
any of the predefined names listed in Predefined register and coprocessor
names on page 3-9.
list-of-registers
is a comma-delimited list of register names and/or register ranges. The
register list must be enclosed in braces.
Usage
Use RLIST to give a name to a set of registers to be transferred by the LDM or STM
instructions.
LDM and STM always put the lowest physical register numbers at the lowest address in
memory, regardless of the order they are supplied to the LDM or STM instruction. If you
have defined your own symbolic register names it can be less apparent that a register list
is not in increasing register order.
Use the -checkreglist assembler option to ensure that the registers in a register list are
supplied in increasing register order. If registers are not supplied in increasing register
order, a warning is issued.
Example
Context RLIST {r0-r6,r8,r10-r12,r15}
