These attributes are supported by the RL78 back end:
interrupt ¶brk_interruptThese attributes apply to functions.
They indicate that the specified function is an interrupt handler. The compiler generates function entry and exit sequences suitable for use in an interrupt handler when this attribute is present.
Use brk_interrupt instead of interrupt for
handlers intended to be used with the BRK opcode (i.e. those
that must end with RETB instead of RETI).
saddr ¶This attribute applies to variables.
The RL78 back end supports the saddr variable attribute. This
specifies placement of the corresponding variable in the SADDR area,
which can be accessed more efficiently than the default memory region.
