These function attributes are supported by the C-SKY back end:
Use of these options requires the
command-line option to enable support for the necessary interrupt stack instructions. They are ignored with a warning otherwise. See C-SKY Options
asmstatements can safely be included in naked functions (see Basic Asm ). While using extended
asmor a mixture of basic
asmand C code may appear to work, they cannot be depended upon to work reliably and are not supported.
