6.33.16 MCORE Function Attributes
These function attributes are supported by the MCORE back end:
naked
This attribute allows the compiler to construct the requisite function declaration, while allowing the body of the function to be assembly code. The specified function will not have prologue/epilogue sequences generated by the compiler. Only basic
asm
statements can safely be included in naked functions (see Basic Asm). While using extendedasm
or a mixture of basicasm
and C code may appear to work, they cannot be depended upon to work reliably and are not supported.
